Technical Specifications 1. Background:

The geographical location of Maharashtra is bounded between latitude 16.4o to 22.1o N and longitude 72.6o to 80.9o E. The geographical area of Maharashtra state is 307.71 Thousands Km2 which is @ 9.4% of the total geographical area of India. Major river basins in the state are the Krishna river with its major tributary as Bhima, Godavari, Tapi, West flowing rivers of Konkan strip and small portion of Narmada river on north. The Krishna, Godavari, Tapi and Narmada basins do not wholly lie in Maharashtra but territory of Maharashtra is formed of the regions of their sub-basins. Maharashtra State Water Policy (July, 2003) envisages that the water resources of the state shall be planned, developed and managed via a multi-sector approach at the river basin and sub basin scale. The policy states that the distress in water availability during deficit period shall be shared equitably amongst the different sectors of water use and also amongst upstream and downstream users. The rainfall in each basin varies with respect to space and time to great extent. 1.1. West flowing rivers south of Tapi (Rivers of Konkan strip): Number of rivers originates from Sahyadri and flow westward to Arabian sea through Konkan Strip. Damanganga, Surya, Vaitarana, Ulhas, Karla, Kundalika, Kal, Savitri, Vashishthi, Shastri, Gad, Karli, Tillari and Terekhol are prominent rivers. These rivers are of shorter length holding fair amount of water during monsoon but run totally dry during summer months. The incidences of natural calamities such as land erosion, salt water intrusion, land subsidence etc. are often in Konkan. The total length of rivers in Konkan is @ 1609 Km. The annual rainfall in Konkan is between 2000 to 3500 mm. The rainfall is very intense during June to September. Surya, Vaitarna, Modak sagar, Tansa, Bhatsa, Tillari are Major dams in Konkan area. Panvel, Nagothane, Pen, Chiplun, Mahad are flood prone towns. The Mahad experienced heavy floods in 1923, 1976, 1989 and 1994. Mithi river flooded in July 2005. Mumbai city, Thane, Raigad and Ratnagiri districts were affected by flooding in 2005. On July 26, 2005, 944 mm rainfall was recorded in 24 hours at Santakruz in Mumbai. 1.2. Tapi and Narmada Rivers: Tapi and Narmada are the two west flowing rivers coming from Madhya Pradesh state and flowing down to Gujrat state through Maharashtra. Narmada River forms 54 km long common boundary along northern border. Purna, Bori, Aner, Panjra are the tributaries of Tapi and Pedhi, Katepurna, Mum and Nalganga are the tributaries of Purna. Tapi River in Maharashtra is 208 Km.The Katepurna, Wan, Chandrabhaga, Purna, Chankapur, Girna, Hatnoor are major dams in Tapi basin. Akola, Jalgaon are flood prone cities in Tapi basin. Annual average rainfall varies from 700 -1000 mm in most part of the basin. Devganga, Devnad, Udai are tributaries of Narmada in state. Jalgaon and Dhule are drought prone area. 1.3. Godavari River: Godavari the longest river in Maharashtra (968 Km) originates at Tryambakeshwar in Nashik District and enters Andhra Pradesh near Dharmabad in Nanded District. It again flows for about 48 Km along southern boundary of Gadchiroli distict andin enters Andhra Pradesh. On south Darna, Pravara, Sindhphana, joins Godavari. Purna joins from north. The Nanded is the flood prone city in Godavari. Also Nashik, Kopargaon, Newasa, Sangamner, Paithan are flood prone cities/towns. Gangapur, Mula, Bhandardara, Jayakwadi, Yeldari, Siddheshwar, Lower Dudhna, Lower Terna, Manjra are major dams in Godavari. Manjra river originates in Beed District and flows through Latur and enters into Karnataka and Andhra Pradesh. It joins Godavari in Nanded District. This river portion of Godavari covers mostly Marathwada region. The districts namely Aurangabad, Jalna, Beed, Latur, Osmanabad, Nanded,Nashik, Parbhani etc. normally suffers drought. In Vidarbha region, confluence of Pranhita (Wardha and Wainganga are major tributaries) with Godavari is near Sironcha. Length of Wainganga in Maharashtra is 476 Km. The Chulband, Human, Dina, Khobragadi join Wainganga from eastern side however Kanhan and Wardha joins it from western side. In Vidarbha region, Wainganga (Bhandara district and Bramhapuri taluka (Chandrapur)), confluence of Wardha and Penganga (Chandrapur proper) are flood prone. Khadakpurna Upper Peinganga, Upper Wardha, Pench, Bawanthadi, Itidoh, Gosikhurd are major dams in Vidarbha region. The districts namely Buldhana, Akola etc. normally suffers drought in Vidarbha. 1.4. Krishna and Bhima River basin: North-south flowing Krishna and South-east flowing Bhima are major rivers of south Maharashtra. Krishna rises near Mahabaleshwar. The Krishna is 282 km long in the state. On west it is joined by Koyna, Venna, Panchaganga while Yerala joins it from east. Bhima river rises near Bhimashankar in Pune district and flows through Pune and Solapur district. Ghod, Man, Pawana, Neera and Sina are the main tributaries that join Bhima. The length of Bhima in Maharashtra is 451 Km. It joins Krishna on the Karnataka-Andhra Pradesh boundary near Raichur. Krishna, Panchganga, Warna, Mula Mutha, Bhima are flood prone rivers. The Sangli, Kolhapur, Patan, Karad, Kurundwad in Krishna and Pune, Shirur, Daund, Pandharpur are flood prone cities/towns in Bhima river basin. Dhom, Dhom Balkawadi, Kanher, Urmodi, Tarli, Koyna, Warna, Dudhganga in Krishna and Panshet, Warasgaon, Temghar, Mulshi, Pawana, Chaskaman, Dimbhe, Manikdoh, Pimpalgaon Joge, Ghod, Ujjani, Nira Deoghar, Bhatghar, Veer,

Gunjawani are major dams in Bhima basin. The Krishna and Bhima basin experienced heavy floods in 2005 and 2006 year which caused heavy loss to lives and property. The Water Resources Department (WRD) of Government of Maharashtra (GoM) is entrusted with the surface water resources planning, development and management. A large number of major, medium and minor water resources development projects (reservoirs and weirs) have been constructed in Maharashtra. In Maharashtra around 1650 large multipurpose dams exists in above mentioned five river basins. More than 100 dams are gated. Though, the reservoirs in Maharashtra are not specifically provided with flood cushion, they have moderated flood peaks to considerable extent by proper reservoir operations. The reservoirs are multipurpose including hydropower, irrigation, domestic and industrial uses and are operated with rigid schedules as single entities based on the historical hydro-meteorological data and experience gained. These methods are often not adequate for establishing optimal operational decisions, especially where integrated operation of multiple reservoirs for flood management is contemplated. In addition, manual data observation and transmission results in a considerable time lag, between data observed in field and its communication to decision making level which sometime leaves little time, for flood forecasts. The Ministry of Water Resources (MoWR), Government of India (GoI) has implemented Hydrology Project Phase II (HPII), which was a follow-on to the Hydrology Project-I (HP-I). During HP1, the Hydrological Information System (HIS) was developed for the entire state of Maharashtra and the data is monitored manually 1-2 times a day. 1.5. Real time DSS Installed for Krishna Bhima Basin in HPII: Under HP-II project, Real time data acquisition system (RTDAS) is installed and commissioned for Krishna and Bhima basin of the state. Real time decision support system consisting of real time stream flow forecasting and integrated reservoir operation system for Krishna and Bhima basin is also developed to manage the floods and operate reservoirs optimally for multiple uses. The conventional Hydro meteorological network (HIS) developed in HPI, consisting of rainfall stations, river gauge stations, full climate stations, reservoir water level stations, spillway gates of reservoirs in Krishna Bhima basin is upgraded by installing different kinds of electronic sensors, data collection platform, solar panel, solar charger, batteries etc., and employing VSAT, GSM communication system to convey data in real time mode at an interval of 15 min to VSAT Master station/data center at Pune. This real time data and 72 hrs quantitative precipitations forecast on 9 km X 9 km grid, received from RIMES Bankok and NCMRWF, New Delhi is input for decision support system developed in HPII. The real time DSS developed is now facilitating reservoir operators to act on time and prepare stakeholders for the floods. The water level, inflow and outflow forecast for reservoirs, forecast of river water level and flow is helping in taking the decisions for optimal operation of reservoirs well in advance. In addition, the reservoir operation system is facilitating in the optimization of the storages for ensuring flood cushion and improving agricultural productivity. 1.6. Scope of Proposed Work in General: 1.6.1.The State of Maharashtra is now further proposing to upgrade RTDAS of Krishna Bhima basin installed and commissioned in HPII by providing water level and flow measurement sensor at head of selected canals, spillway gate sensors for remaining dams, discharge measurement sensors at head of major selected drinking water/industrial water supply pipeline from reservoirs, automated pan evaporation sensors at major reservoirs and few automated rainfall stations and automated river water level and river discharge stations as a gap filling if needed. The ADCP’s will also be part of present assignment. The automated water quality monitoring stations needs to be installed for few hot spots identified in the basin. As far as possible these additional sensors will be integrated with existing system if site situation permits to save the cost of DCP, communication equipment etc. Few selected major dams, spillway gates will be equipped with supervisory control equipment. These equipment for computerized remote control system and software will help in operation of spillway gates remotely in case of emergency flood situation if manual operation fails. Computerized remote control system for Flood Regulation for dams will utilize the reservoir inflow forecast available through real time flood forecasting and reservoir operation system already developed by Consultants in HPII. The State has also proposed to monitor water level and discharge of main canal (Ujjani) as a pilot, by providing RTDAS comprising canal water level and canal discharge stations located at cross regulators; distributary head, escapes and any such important monitoring points. The Ujjani canal data will be transmitted to Real Time DSS Center Pune by employing GSM communication system. The RTDAS comprising real time hydro meteorological network of rainfall stations, river gauging stations, full climate stations, reservoir water level stations, gate sensors for spillway gates will also be installed for rivers south of Panchganga in Maharashtra. This data will be transmitted to Real Time DSS Center Pune by employing VSAT/GSM communication system. The entire RTDAS needs to be operated and maintained for 7 years. Also existing RTDAS in Krishna and Bhima basin comprising 249 stations with RTDSS at Pune needs to be maintained further for 3 years after present four year O and M contract expires. Further for entire state, Ground Station Antenna with allied equipment and softwares will be installed at RTDSS Center Pune, which will acquire and provide input of earth observation products viz. rainfall and climate from satellites and will be an important input for IWRM of Godavari basin, RTDSS of Krishna Bhima, Early flood warning system of Konkan area, Drought monitoring and flood forecasting system for rivers of

Vidarbha (VainGanga, Painganga) and Tapi river in particular and further studies in general. This system will also be operated and maintained further for 7 years. The existing real time DSS center Pune will also receive data of Godavari basin (Marathwada region), Konkan rivers and also network of rivers south of Panchganga river, Ujjani canal network in real time mode needing upgrading the capacity of servers and allied equipment and facilities at real time data center Pune. 1.6. 2. The State has proposed to implement Integrated Water Resources Management for Godavari basin up to Jayakwadi dam. However RTDAS comprising real time hydro meteorological network of rainfall stations, river gauging stations, full climate stations, reservoir water level stations, rainfall and evaporation sensor for major reservoirs, gate sensors for spillway gates, water level sensors at head of selected canal, sensors for major industrial or municipal water supply pipe lines from selected reservoirs will be installed for entire Godavari i.e. up to Babhali barrage. As a pilot a major dam will be provided with supervisory control to operate spillway gates remotely in case of emergency. The ADCP’s will also be part of present assignment. The WALMI Aurangabad is developing IWRM system/model and this model is under development through consultants appointed separately through another contract. The reservoir inflow forecast derived through model will be used as input for computerized remote control system/supervisory control system of spillway gates. The proposed RTDAS will provide input for IWRM model. The automated water quality monitoring station needs to be installed for a hot spot identified in the basin as a pilot. This data will be collected at existing real time decision support system center at Pune installed and commissioned in HPII. However this data will also be available at Aurangabad sub center online in real time mode for modelling for drought monitoring and flood forecasting work/IWRM work. Necessary servers, computers, display systems with allied equipment will be part of this work. The RTDAS with this sub center needs to be operated and maintained for 7 years. The Godavari basin is also having existing RTDAS for few reservoirs, comprising of automated reservoir water level stations, automated rainfall stations in catchments of reservoirs and also few automated river water level stations. These stations needs to be inspected in detail in view of equipment specifications, their robustness, compatibility and their possible integration in to present system proposed for installation. This existing RTDAS will have to be operated and maintained further for seven years. 1.6.3. The State is proposing to implement real time flood forecasting and reservoir operation system and drought monitoring for Godavari basin portion (Vainganga Painganga rivers) of Vidarbha region. RTDAS comprising real time hydro meteorological network of rainfall stations, river gauging stations, full climate stations, reservoir water level stations, rainfall and evaporation sensor for major reservoirs, gate sensors for spillway gates, water level sensors at head of selected canal, sensors for major industrial or municipal water supply pipe lines from selected reservoir (Pench Reservoir) will be installed for Godavari river of Vidarbha region.

2.2 General Technical Concept

2.2.1 Capacity and Implementation Constraints Currently, the State of Maharashtra is managing the existing hydro-meteorological network developed through HP I and HPII extremely well. The State currently outsources some of the task of hydro-meteorological data collection. The State has also had to make arrangements to pick up the data from the various automated and non-automated stations, subject the data to quality control and then store the data. With the implementation of this RTDAS, the relay of information from the remote stations to the office and data center will no longer be performed manually, though manual data collection will still be required in the event the failure of the transmission of data or otherwise been interrupted. The State of Maharashtra has decided to continue to contract out services for the maintenance of

this network which includes the collection of all data, with the eventual destination being the data center at Pune, Nagpur with sub centers at Aurangabad, Jalgaon and Thane. The State will develop a position within the organization that will serve as a specialized in all facets of the real time data acquisition system. This specialized organization will be responsible for managing the contract of real time data acquisition system (RTDAS). The State of Maharashtra will likely incorporate this expertise within a group of State Government Engineers and Technicians. These State staff will be critical in assuring the viability and sustainability of the RTDAS. This expertise may then be transferred in phases to field offices that are involved in the flood management and management of water resources of the state. A great portion of the effort to operate and maintain the RTDAS network will however be performed by the Supplier.

2.2.2 General Approach The concept of implementation on which the present technical specifications and special conditions are based intends to combine the advantages of modern Data Collection Platform (DCP), data storage, processing and data communication technologies with the requirements of high availability and sustainability required by such an important project. Preference will be given to robust, reliable technology. Some data collection sites are located in very remote areas and should require annual maintenance only, so the selection of equipment and civil design will consider this aspect. The cost of servicing a real time hydrologic network will exceed the cost of the purchase several times over the life of the network. It is, therefore, of central importance that the State of Maharashtra RTDAS network will have the greatest possible reliability, thus minimizing the maintenance to the extent possible. Special protection against environmental factors is often justified, even at high initial costs. Wherever possible, the Supplier should combine data from stations or sensors in close proximity using wireless, unlicensed radio transmissions to a single point, then employing VSAT or GSM data communications from a single location. For instance, there are numerous locations where a rain gauge will be located within the proximity of a reservoir water level sensor, and/or gate opening sensor. These sensors should be combined within a single station which will eliminate the costs of VSAT or GSM transmitters and the recurring costs associated with these devices. Unlicensed wireless communication devices are required to be certified for use in India by the competent authority. Maintenance is an integral part of any system and a system that has the challenges of unattended operation in remote, exposed areas stresses the need for a well thought out approach to maintenance. The corrective maintenance will be required for data collection issues, whether they may be component failures or due to environmental issues. To minimize corrective maintenance and to increase the performance of the monitoring network, a well-organized preventative maintenance plan is highly recommended. The preventative maintenance is required for all system components as well as the infrastructure in place to house the electronic data collection components. It is recognized that the maintenance of a monitoring network is often grossly underestimated as well as underperformed task. This leads to reduced life expectancy of the equipment and possibly the collection of misleading data during the period of operation. A strong maintenance plan will be the foundation for sustaining the State of Maharashtra’s monitoring network operation over the expected lifetime of the technology, which is considered to be 10-15 years. Data communication will either be VSAT and/or GSM, based on the crucial nature of the data and/or availability of GSM. The Supplier will be responsible for making all licensing arrangements for the sites requiring VSAT /GSM. The Technical Specifications consist of the installation of the real time data acquisition system for river basins in Maharashtra. This includes a VSAT Master station, which shall be able to receive data from appropriate Indian satellite. This shall include the design, manufacture, factory testing, deliver to site, installation (including the associated interface wiring/termination), commissioning and site acceptance testing, supply of mandatory spares, training and documentation. Data Collection Platforms (DCP), monitoring system hardware and software shall interface and be fully integrated and tested with the new VSAT Master station to be provided and established. The Ground Station Antenna to receive earth observation products of rainfall and climate with allied equipment and relevant software needs to be installed at Pune. The requirements are given below in respect of each major component of the system. The Supplier shall ensure that the fundamental requirements stated in this document are not compromised.

4. Functional Requirements

Transition to automated observations with real time data communication can lead to a discontinuity in the measurement record if the process is not specified and managed carefully. The benefits of automation with real time data communication include cost effectiveness, high frequency data, better ability to detect problems with measurements, faster access to data, consistency and objectiveness in measurement, and ability to perform automatic quality monitoring. All selected sites should conform to the extent practical to WMO guidelines. The new real time data collection network sites have been proposed by the State of Maharashtra. The State will be responsible for obtaining permission to use property. River stage and reservoir water elevation including gate openings, reservoir evaporation, canal water elevation and discharge, drinking or industrial flow will be logged every 15 minutes and transmit using both self-timed and random (event) transmission as allowed by ISRO.

5. Technical Specifications 5.1 Classification of Remote Stations There are six categories of stations that will be the real time hydrologic data collection network for the State of Maharashtra. These categories have been devised to make the needs of this specification more straightforward. The ten categories of stations are listed below. Category I Existing Cooperator Stations Category II Automated Rainfall Stations Category III Automated Full Climate Stations Category IV Automated River Water Level (stage) and River Discharge Stations Category V Automated Reservoir Water Level and Outflow Discharge Stations Category VI Automated Measurements of Spillway Gate Opening Category VII Automated Canal Water Level (stage) and Canal Discharge Stations Category VIII Automated rainfall and Pan Evaporation Stations Category IX Automated Industrial/Drinking flow measurement stations Category X Automated water quality monitoring stations 5.2 Real time Hydrologic Data Collection Network: These remote stations are described as follows:

5.2.1 Category I – Existing Co operator Stations This category consists of Automatic Rainfall Stations and Auto Weather Stations (AWS) that are operated by IMD, CWC and ISRO. Data from these stations that are of interest to the hydrological assessment in river basins will be collected by the VSAT Mater station located at the data center at Nagpur, Aurangabad, Jalgaon and Pune as per the basins. The Supplier is not responsible for the operation and maintenance of these stations, but only programming the VSAT Master Station to collect the data from their respective data centers, and then pass it on to the DSS. A list of these stations is provided in Appendix A under Category I stations. The Supplier will need to coordinate with the operating Supplier to get the decoding specifications so that the data can be received, decoded and made available to the DSS. There will be no civil works required by the Supplier for these stations.

5.2.2 Category II – Automated Rainfall Stations This category describes either new or upgraded data collection stations that will measure precipitation and transmit this data to data center at Nagpur and Pune as per the basins. Some of these stations will use VSAT data communications while other stations will use the GSM data communications. All rain gauges will be tipping bucket type gauges. There are no requirements to measure frozen precipitation. The automated rainfall stations will be often times remotely located. The State of Maharashtra will provide the civil works related to preparing the site. The Supplier will provide all accessories required to secure the DCP and radio and any other accessories needed for mounting the DCP or sensors. The Supplier will provide small building/gauge house (plan area @ 5 Sqm and 3m height) to mount the data logger, VSAT modem, antenna, batteries, solar charger and polyphasor. The building must be water proof and sealed against the infestation of insects and rodents. The building will be contained within a fence for additional security. The rain gauge will be mounted 0.8 to 1m above the ground and will be located in such a way where the WMO guidelines on exposure are followed (i.e. structures, trees cannot be closer than twice the difference between the orifice height and the height of the object).

5.2.3 Category III – Automated Full Climate Stations The State of Maharashtra is proposing to install automated FCS either at new locations or upgrade the selective existing FCS to provide automatic measurement with data communication for the following parameters:

Temperature Relative Humidity Wind Speed Wind Direction Precipitation Solar Radiation Barometric pressure

The DCP will be able to use these parameters and compute derived parameters such as minimum/maximum thresholds, wind run and other parameters that are calculated from the existing network. These parameters will be used to compute the evaporation at climatic station. The specifications for these sensors are provided in the Equipment Specifications of this document. The sensors shall follow WMO guidelines for the placement of such sensors. The AFCS will need to be located adjacent to the existing FCS without interfering with the measurements of the FCS or the AFCS. The existing FCS will continue to be maintained and monitored by the State, while the AFCS will be installed and maintained by the Supplier.

A stainless steel or FRP instrument box will be provided by the Supplier to mount the DCP, VSAT/GSM transmitter, batteries, solar charger, and lightening discharge protection device. The antenna and solar panel can be mounted on one of the poles supporting the stainless steel instrument box. The instrument box must be waterproof. Connections to the box must be performed in such a way as to prevent insects and other pests from entering the box. The Supplier will provide all civil works for these stations including the building for housing the equipments.

5.2.4 Category IV – Automated River Water Level (stage) and River Discharge Stations This category describes either new or upgraded data collection stations that will measure river stage and transmit this data to data center at Nagpur or Pune as case may be. Some of these stations will use VSAT data communications while other stations will use the GSM/GPRS data communications. The Supplier will provide all civil works for these stations, including a gauge house to protect the equipments from theft as well as environmental effects such as insect/rodent infestations or water intrusion. The water level measurement technology will either be made from a bubbler system, radar sensor or a stilling well/float encoder principal. River Water level recording stations will require a gauge house, defined as a suitable building/gauge house to provide the protection of the equipments from both the environment and tampering.

5.2.5 Category V – Automated Reservoir Water Level and Outflow Discharge Stations This category describes data collection stations that will measure reservoir water elevation and transmit this data to data center. Some of these stations will use VSAT data communications while other stations will use the GSM data communications. The Supplier will provide all civil works for these stations, including a gauge house (where it is not available) to protect the equipments from theft as well as environmental effects such as insect/rodent infestations or water intrusion. The water level measurement technology will be a Radar system, bubbler system or a stilling well/float encoder principal. The data of spillway gate, canal water level and discharge station near dam and/or drinking/industrial flow measurement sensor need to be combined together if possible and common DCP and communication system may be used.

5.2.6 Category VI – Automated Measurements of spillway Gate Opening This category describes the requirement for sensors placed on gates such as spillway gates to measure gate openings. The measured gate opening will be used along with water elevation to determine accurate discharge past the gates. The Supplier shall also be required to collect the information necessary to calculate discharge past the gates in real time, though this calculation can be made as part of computations in the data center immediately upon receipt of the data from either VSAT or GSM. In some situations, the outflows might be measured directly in off-take canals downstream of the dam. The Supplier shall propose measurement options for gauging such flows as an alternative to monitoring gate sensors. The Supplier shall be responsible for all civil works related to the installation of the sensor, though plans for civil works must be approved by the Purchaser prior to the acquisition, installation and commissioning of the sensor. Regardless of the sensor solution, the flows past the gates must be accurate to within 5% of the actual flow.

5.2.7 Category VII Automated Canal Water Level (stage) and Canal Discharge Stations: The discharge past the canal gates at head of main canal or at cross regulator or at head of regulatory can be measured by providing gate sensors and level sensors at upstream and downstream of gates or the Supplier shall propose measurement options for gauging such flows as an alternative to monitoring gate sensors (e.q. providing side looking ADCP) or combination of level sensor and movable ADCP). The Supervisory controls work for pilot canal needs provision for gate motorization, supervisory equipment, DG set, inverter etc. apart from above mentioned sensors. This data will be communicated to data center using GSM communication.

5.2.8 Category VIII Automated Rainfall and Pan Evaporation Station: At major reservoirs, pan evaporation needs to be measured. The rainfall data is also required to calculate pan evaporation. Therefore station shall combine rainfall sensor and pan evaporimeter. This data will be communicated to data center using VSAT communication.

5.2.9 Category IX: Automated Industrial/Drinking flow measurement: To measure the water supplied for drinking or industrial purpose from reservoir, the sensors measuring flow through pipes/closed conduits needs to be installed. This data needs to be communicated to data center through VSAT or GSM communication.

5.2.10 Category X: Automated Water Quality Monitoring Stations: Appropriate water quality monitoring stations will have sensors to measure water quality in real time for various parameters for identified hot spots in each basin. The data needs to be communicated to data center through VSAT or GSM communication.

5.3 Telemetry The data communications employed on RTDAS network will use a combination of VSAT communication and GSM radio communications. VSAT satellite communications will be placed at sites which are of highest priority for real time data communication and/or that do not have available communication from GSM. All stations have had in in-situ radio path survey, where a mobile phone signal was detected, and/or a line-of-sight path to the VSAT confirmed. It will be the responsibility of the Supplier to confirm radio path and mobile network coverage. The recommended data communication technology is finalized tentatively. Telecommunications and data collection platforms can be expensive combining sensors from measurement points into single data collection platforms and radio transmitter to reduce the cost of the network is the key. The use of unlicensed spread-spectrum radios or other technology is an example of a means to move sensor data to a single data collection platform.

A continuous earth wire of required size should be laid along with the cables the cost of which should not be claimed by the contractor. The cables shall be bent with radius not less 16 times dia. of the cable. The cable entering the switchgears required to have sharp bends shall be provided with connecting chambers. The cables shall be one length and no joints will be allowed. The portion of these cables to be erected on wall shall follow the following procedure. The position of cable saddles will have clearance 50 cms between the saddles.

Diesel Generators and AMF panels Diesel Generators to be provided with AMF panels of suitable capacity for operation of gates and the Local control System. In case of Dams with existing DG sets, AMF panels to be provided for automatic switchovers in case of loss of mains power

Local Dam control Software Remote Control system at Dam will collect the data from various existing /new sensors like Gate position

sensors, Level sensors, limit switches and transmit the same to Dam control software. Dam Control Software will continuously monitor & display Upstream/Downstream Level, Spillway Gate openings, Inflow, Discharges through Spillway gates, flow monitoring stations, level monitoring stations, percentage Storage, Live storage, Gross Storage, Time to reach FRL & MWL. This historical data will be continuously logged in to Computer for further analysis & display. Dam control software will receive commands from Master SCADA centre, in the form of set points for discharge base/ level based/ gate opening based operations and also the flood conditions required for Dam operation.

Gate Operation for Spillway: Automatic Mode:

The gates will be operated automatically from the commands received from Master SCADA centre. The operation of gates will be strictly as per the reservoir operation schedule and gate operation schedule approved by the competent authorities. While operating spillway gates, situation in the river downstream of the Dam will be taken into consideration. In the event, when any gate causes mechanical or electrical failure, an alarm will be generated for non-functionality of the particular gate. Semi-Automatic Mode:

The facility to operate gates as per the current instructions from the authorities by over-riding the automatic operation is provided in the Dam control software. This option has following various modes of operation-

Set level mode Gate openings mode Discharge mode Anticipatory mode

Set Level Mode:

In this mode of operation, operator can enter the particular reservoir water level to be maintained automatically and period for retaining the set level in the reservoir by releasing excess water. This operation is over-ride to the reservoir operation schedule set-out. Gate openings mode:

In this mode of operation, operator can set opening for particular gate for defined time period and gate will be adjusted to the desired gate opening. After expiry of the time period, gate will be automatically set to its original position or as per the requirement of situation in automatic mode of operation. Discharge mode:

In this mode of operation the operator can set the discharge rate and quantum of water to be released or the discharge rate for the defined period and Dam control software system will calculate and adjust the opening of gates to let out the desired flow. After completion of time period the system will automatically reposition the gate to its original position or as per the demands of situation in automatic mode. Manual Mode:

The spillway / Canal gates can be operated in manual mode for flood / discharge regulation. In this case, the Dam control software will act as monitoring system and operation will be carried out by the engineer / operator at site. This facility is provided for regulation of flood/canal discharges even when the some component of the remote control system is not functioning properly. Event log:

Each and every event at the Dam site will be logged by the software system along with the password of the operator in encrypted form. The data collected from the field stations, calculated by the system will also be logged in the

Environment Conditions Operating Temperature : - 5 to + 500 C Storage Temperature : - 40 to + + 700C Relative Humidity : Up to 100 %

system along with the date and time stamp at predefined time interval. This data will be used to refine the operation and analysis. Master SCADA software Master SCADA software will be compatible to third party flood management and decision support software for integration to integrated reservoir management system. Master SCADA software will receive information from all the local dam control software and also send control commands in the form of set points for discharges, levels, gate opening etc. The Master SCADA will receive the data from flood management software and after authorized commands from operators will issue control commands to Dams. The SCADA software shall be compatible to the existing RTDAS and RTDSS software installed. The SCADA software will be up scalable. Data and Web server specifications
