The regular oilcontamination areas shall also be segregated and discharge from these areas shall becollected in catch basins to be joined in oily water sewer. Oily water sewer shall consist ofcarbon steel sewer, funnel points, clean outs, RCC catch basins, RCC manholes, ventpipes, flame arrestor etc.
2.3 Contaminated Rainwater Sewer (CRWS)
The areas which are contaminated due to floor wash drains etc. inside unit boundariesshall be demarcated. Contaminated areas collected in catch basin shall be drainedthrough CRWS while un-contaminated areas, normally at periphery of the units shall bedrained through ditches covered with grating.
CRWS shall consist of undergound carbon steel sewer with corrosion protection, funnelpoints, clean outs, RCC catch basins, RCC manholes, vent pipes, flame arrestor etc.
Open ditches of units should have a bypass either to the CRWS or to storm water, drainsof offsite.
This system collects surface drainage from areas containing hydrocarbon - bearingequipment. This water must pass through a treatment facility before being discharged intoan uncontaminated system or natural body of water e.g. river or a stream.
2.4 Closed Blow Down (CBD) sewer
This system picks up drains around boilers and steam drums and is run as a separatesystem preferrably to the battery limit.
The system shall be designed as per P&ID and the effluent collected from equipmentsthrough funnel points and underground piping system shall be connected to theunderground CBD drum.
2.5 Amine Blow Down (ABD) sewer
The amine blow down system (ABD) shall be designed as per P&ID.
The effluent shall be collected from equipments through above ground points into closefunnels connected to underground system. The main header shall be connected to theunderground Amine sump / drum.
2.6 Fire Water Sytem
This system consists of a fire hydrant network around a process unit or equipment, withbranches as required for hydrants or monitors to protect the unit in case of fire.
This is a close loop system starting from Firewater storage and pump to the specificlocation of hydrants and monitors. This is always kept under a predetermined workingpressure level.
2.7 Potable Water System

2.9 Underground Electrical and Instrument ducts
In the beginning of a project, the decision to route the major electrical and instrumentconduits - above ground in the piperack or buried below grade shall be taken.
In case underground route is selected, electrical and instrument engineers shall beconsulted for the optimum layout of ducts by the plant layout engineer.
Where conduits enter the unit through a pull box and cables come above ground forrouting upto the terminal points, the space shall be kept free of piping, equipment orassociated maintenance access.
3.0 KEY WORDS3.1 Catch Basin
This device is used to collect surface drainage with an outlet liquid seal and sediment trap.
The sketch UGP9 illustrates a typical catch basin feature and UGP17 illustrates a typicallocation of catch basins.
The maximum area coverage of a catch basin is approx 150 sqm. ie. 12mx12m or15mx10m.
The area covered by a catch basin should be of square configuration, as far as possible.
The catch basin should be located in the middle of the area as far as possible.
Slope of pavement 1 in 100, e.g. HPP (Ridge of catch basin area = 100.00) and LPP (atcatch basin peripherial drain = 99.85)
No catch basins or manholes should be located within 15m radius of heaters.
No vent pipes should be located within 15m of the heaters.
Area drainage around heater areas shall be done by pavement sloping towards openditches. Each catch basin shall be connected to manhole and shall be provided with fireseal.
3.2 Sealed Manholes
Sealed manholes shall be provided at
a. Unit battery limit and
b. Junction of sewers and at change in size of main header.
These devices are provided so that the unit area is isolated from any fire in offsitearea/sewer.
Within the unit area, sealed manholes in main headers should be provided in suchlocations so that each sub-unit within the unit is isolated from the other areas. In case, thisdemarcation is difficult, one sealed manhole for every 30m length of main sewer in the unitshall be provided.
Sealed manhole with bent pipes seal type shall be used for carbon steel pipes upto size16" NB and for greater than dia 16" NB and for all diameters of RCC pipes doublecompartment type manholes should be used.
3.3 Invert elevation
This term, usually associated with any underground line, refers to the elevation of theinside bottom of the line. Because of the wide range of materials used in the undergroundpiping system / drainage system with varying wall thickness, it is the constant that is usedto set the elevation on construction drawings.
The starting invert level of CRWS shall be normally 750mm below HPP (High Point ofPaving)

The invert level at outlet point of CRWS and OWS shall be normally 1500mm below FGL.
3.4 Cleanout
A cleanout is a piping connection in a sewer system that is located at grade level forinspections or for cleaning the system.
3.5 Vent Pipes
Vent pipes shall be located along piperack columns or building columns and should betaken 2m above the building parapet or last layer of pipes on a piperack.
3.6 Valve Pit / Maintenance pit for flanges and instruments.
When the underground system needs valves for isolation and instruments for control, thenormal practice is to enclose these valves and instruments in a RCC pit with cover. Thesevalves and instruments in a pit can be operated as well as maintenance work can be donewith ease.
4.0 PIPING ARRANGEMENT - UNDERGROUND4.1 The overall Plot Plan allocates the space for the major underground services in the
beginning of the project.
The cooling water supply from cooling water pump discharge to the various units as wellas the cooling water return from the various units to the top of cooling tower is routed in asimple, straight orientation at a suitable depth avoiding any major road crossings.
A typical cooling water and potable water system is illustrated in sketch UGP1.
Cooling water cross over piping is illustrated in sketch UGP2.
Cooling water lines to heat exchangers are typically illustrated in sketch UGP3.Cooling water lines to pumps for various cooling requirements is illustrated in sketchUGP4.
4.2 The potable water system supplies to various units and a branch is taken to theemergency eyewash and safety shower station as illustrated in sketch UGP5.
4.3 Fire water system protects each piece of equipment by providing water through hydrants,monitors or deluge spray systems.
Each process unit will have its own underground firewater piping loop system.
4.4 A typical hydrant and monitor installations are illustrated in sketch UGP7 and a typical fire-monitor is shown in sketch UGP8.
4.5 Normally, chemical process units will have multiple drain systems designed to collect allcorrosive or toxic chemical waste as well as surface drainage around the equipment.
Drain / sewer system in a plant can be categorised as :
- Uncontaminated storm water
- Contaminated storm water
- Oily water sewer
- Chemical and process sewer
- Sanitary sewer
- Blowdown system

- Uncontaminated storm water system generally collects all service water from equipmentareas, access ways, roadways to equipment. This collection is done through area drains,catch basins, roof rain water downcomers.
- Contaminated storm water system collects surface drainage from areas containinghydrocarbon processing equipment. This system water must pass through a treatmentfacility before being discharged into an uncontaminated system or natural body of waterviz. river or a stream connected to a river.
- Oily water sewer system collects waste, drips, leaks from equipment and piping in noncorrosive process equipment area. The designer should identify all the specific drainpoints in consultation with the process engineer.
- Chemical and process sewer system recovers acid or chemical drains from equipment /piping as well as surface drainage by providing curbing and drain sump around suchequipment.
- Sketch UGP19 depicts a typical process drains - closed system.
- Sketch UGP21 illustrates a typical cross-section of a closed or chemical drain system.- Sanitary sewer system collects raw waste from lavatories and is either connected to the
municipal battery limit or routed to a septic tank.
- Blowdown system picks up drains around boilers amd steam drums and is run as aseparate system. It is permissible to connect the bowdown system to a sewer box in oilywater sewer system downstream of drainage from a furnace.
4.6 Trench Piping
Occasionally, drain piping or process piping should be run below grade but not buried.
Sketch UGP6 illustrates two insulated lines A and B running below grade to a drain tank.The top of the trench is covered with grating but could be covered with RCC slabdepending on the traffic load estimated in the area.
The width of trench should allow adequate clearance to valves and drains as required.
4.7 A typical catch basin is illustrated in sketch UGP9.
A typical sewer box or manhole is illustrated in sketch UGP10.
A typical Dyked area drain sump is illustrated in sketch UGP11.
A typical lift station by vertical pump is illustrated in sketch UGP12.4.8 A process area for the purpose underground drainage is subdivided into block areas with
high point ridge and low point catch basins / pits.
The low point catch pits are connected to manholes.
The manholes are interconnected by sloping piping and led to the battery limit valve pit andfinally discharged into the treatment pond.
Sketch UGP13-14, UGP15-16, UGP17 illustrates the details of the subdivision of theprocess area into blocks with explanatory notes.
Sketch UGP18 illustrates how to handle oily water and storm water system.
4.9 Closed drain system is illustrated by various sketch UGP19-20, UGP21, UGP22.4.10 The underground electrical and instrument cables passing under a road or paved area is
taken through ducts embeded in lean concrete. Sketch UGP23 shows a typicalarrangement of such underground cabling details.
