1. Introduction

1.1 Project Background

The purpose of the Kunming Qingshuihai Water Supply Project

(hereinafter referred to as “The Project”) is to ease the recent tension of water

supply in Kunming. It plans to divert 104 million cubic meter water from the

Xiao Jiang River basin in Dongchuanying of Xundian County in northern

Kunming to the Jinzhongshan reservoir in Songming County, serving as water

supply for the New Airport Development Zone and the East Development Zone.

On December 3, 2004, KMG gave its consent to the implementation fo the

Project through K.Z.F.[2004] No.61 Written Reply on Planning Report of

Kunming Water Supply Project, thereafter, China Water Conversation and

Hydropower Science academy and Yunan Provincial Water Conservation and

Hydropower Investigation and Design Institute conducted the Environment

Impact Assess for the Project.

The projected construction duration of the Project is five and half years

(from early 2008 to June 2013). The Environmental Impact Assessment Report

on the Project (hereinafter referred to as “EIA”) requires environmental

monitoring during the entire construction and operational period, mitigation of

the impact on the project affected area, examination of the effectiveness of

applied mitigation measures, and prompt adjustments of responding measures

based on analytical results of monitoring reports.

In June of 2010, the Kunming Water Supply Group Qingshuihai Water

Sources Development and Construction Branch Company(hereinafter calls as

"the Employer”) contracted Yunnan University to prepare the Environment

Monitoring Report for the Project during the construction period. As of

February of 2012, Yunnan University has Subcontracted with Kunming Xishan

4

District Environmental Monitoring Institute (XEMI) to conduct five times of

environment monitoring on construction activities from the year of 2010 to

2012 (twice per year for the year 2010 and 2011, once in the first half of 2012)

and it has submitted the Environmental Monitoring Report to the Employer.

Based on monitoring results, the Employer informed contractors to make

rectifications within a certain time limit regarding environmental issues during

construction period. Therefore, the environmental impacts during the

construction period have been effectively minimized.

Because the Project was basically completed in July of 2012, all

management responsibilities of reservoirs, water conveyance facilities as well

as related equipments was transferred to the new established project operation

unit—Kunming QingYuan Water Supply Co., Ltd. Therefore, this report is

mainly about the monitoring of the environmental recovery after completion of

the Project. Based on the site surveys and by combining Technical Report of

Monitoring for Kunming Qingshuihai Water Supply Project (from 2010 to

2012), and the monitoring report of May of the year 2013, make a assessment

on the environmental restoration after completing the project. According to the

analysis of previous monitoring reports, we provide corresponding improving

suggestions. This report will provide a theoretical context for further

minimizing environmental impact of project construction.

1.3 Project Components

The Project comprises the diversion of water from 4 locations on the upper

reaches of tributary streams to the Xiaojiang River. The Project consists of the

water sources component and the conveyance works component:

A：Water sources component

The water sources component includes six dams of Shiqiaohe river,

Banqiaohe river, Xintianhe river, Tabizi Spring and Jinzhongshan. Water will

be transferred through a network of tunnels and channels to the Qingshuihai

reservoir. From Qingshuihai reservoir, the water will be transferred through a

combination of pipes and tunnels to two existing reservoirs. The main receiving

reservoirs will be the existing Jinzhongshan Reservoir (to be enlarged by a new

dam, about 600 m upstream from the old dam in Songming County) and

Songhuaba Reservoir (an existing reservoir) to the north / northeast of the

6

present Kunming City. Specifications for these planned works are shown in

Table 1-2.

The Kunming Municipal Government (KMG) is the Executing Agency for

the Project. The Project Leading Group (PLG) has been set up, with the

responsibility of policy guidance and high-level coordination during

implementation. Headed by the Vice Mayor, the PLG comprises representatives

9

from the Kunming Financial Bureau, Kunming Development Reform

Commission, related agencies, and county governments. The PLG meets as

required and will be maintained until project completion.

The PMO has been established within Kunming Development and Reform

Commission. It serves as the secretariat for the PLG and is responsible for

coordinating the implementation of project activities. The specific duties of the

PMO include: (i) ensure adequate interdepartmental cooperation and

interagency coordination, (ii) monitor the progress of project implementation,

and (iii) coordinate communication and interaction among ADB, KWSG and

agencies concerned.

The IA is Kunming Water Supply Group Co. Ltd. (KWSG), which is a

limited liability company incorporated under the 2004 PRC Company Law. The

KWSG is responsible for operating and managing project facilities, direct daily

project management, construction supervision, preparation of progress reports

to the PMO for submission to ADB, and strategic planning for water supply and

management services and operations. KWSG is well organized, with experience

of implementing World Bank and JBIC loan projects. A project implementation

unit (PIU) has been established in the KWSG and is responsible for undertaking

detailed implementation activities. KWSG will retain the services of design

institutes, procurement agencies, and construction supervision companies to

assist with implementation activities.

1.5 Implementation of Environment Monitoring Program

Internal environmental monitoring consists of two types. The first type

requires field sampling and lab analysis that is undertaken by a licensed

environmental institute, for such environmental parameters as water quality, air

quality and noise levels. The second type refers to visual inspections of such

10

things as soil erosion, restoration of vegetation, solid waste disposal and so on.

The field sampling and lab analysis has been conducted, according to the

environmental monitoring program as stipulated in the SEIA, by the Xishan

District Environmental Monitoring Institution (XEMI) under contract to the IA.

Field inspections have been undertaken by the on-site environmental engineer

of the contractor, Environmental Management Office（EMO）officers and

PMO officers on a regular basis.

External monitoring is undertaken by Kunming Xishan District

Environmental Monitoring Institution. Yunnan University is responsible for

reports preparation, and responsible for advising the PMO, IA and construction

contractors on the environmental protection in construction activity.

The implementation status of the environmental monitoring program, as

proposed in the SEIA, is presented in the right column of the Table 1-5. The

detailed results of field sampling and lab analysis are presented in the ensuing

chapter. In summary, the environmental monitoring program has to date been

implemented properly.

1.6 Implementation of Environmental Responsibility Scheme

An environmental management system, consisting of inspection,

monitoring, reporting, and initiating corrective actions or measures, was set up

prior to project implementation. In the design stage, PMO and IA passed the

EMP to the design institutes for incorporating mitigation measures into the

detailed designs of each subproject. The EMP was reviewed and confirmed at

the end of the detailed design, and was finally passed to selected contractors. To

ensure that contractors will comply with the EMP’s provisions, PMO and IA

prepared and provided the following specification clauses for incorporation into

the bidding documents: (i) a list of environmental items to be budgeted by the

11

bidders in their proposals; and (ii) environmental clauses for contract conditions

and specifications.

An EMO was established by the IA prior to the start of the project

implementation. It is charged with the responsibility of coordinating and

supervising the EMP implementation. The EMO is headed a deputy general

manager of the IA. The IA has also recruited an environmental officer who also

serves as the focal point for grievance redress. Meanwhile, the PMO has drawn

the expertise from the Kunming environmental protection bureau in supervising

the environmental management system.

Yunnan University has contracted the Environmental Protection

Monitoring Station of Xishan District of Kunming （hereinafter referred to as

Xishan Institution）to conduct one environmental monitoring in The first half

of 2013. The results of the monitoring were shown in chapter five. The

implementation of the environmental responsibility scheme is shown in Table

offices of these five project points have not been withdrawn yet. Workers in

other works have all been withdrawn, and the temporary construction built in

the duration of construction have been demolished in most parts of work points,

except work points of 1#, 2# and 5#.

During the construction of the Project, the ground above Daping Tunnel

sank, the exit sections of Haidang Tunnel and Yujiazhuang Tunnel had the

phenomenon of subsurface filtration, and Dashuidong Tunnel collapsed and had

the phenomenon of subsurface filtration, the main reason for such problems are

the geological conditions of these areas were poor. But these problems have

been properly solved.

3. Implementation of Environmental Protection Program

3.1 Targets of Environment Management Program

The objective of establishing an EMP is not only to propose appropriate

mitigation measures, but also to recommend establishment of institutions or

mechanisms to monitor and ensure compliance with environmental regulations

and implementation of the proposed mitigation measures. Such institutions and

mechanisms will seek to ensure continuously improving environmental

protection activities during preconstruction, construction, and operation in order

to prevent, reduce, or mitigate adverse impacts. The EMP drew on the

individual EIA reports and on the PPTA discussions and agreements with the

relevant government agencies.

3.2 Implementation of Mitigation Measures

The important aspects of the implementation of mitigation measures are

highlighted as follow:

1) Environmental Clauses in Civil Works Contracts

All civil works contracts contain provisions on workers and community,

environmental protection and protection of physical and cultural relics. The

environmental clauses are summarized as below.

Workers’ and Community Safety

The contractor will take precautionary measures to ensure workers’ safety.

Protective devices will be worn at all times for any person entering the

construction site. Safety training shall be undertaken for workers and staff. In

case of bodily harm to any worker, the contractor will have full responsibility

for medical care and compensation according to PRC labor law. The contractor


2

will also be responsible for any bodily harm and property damage caused by

construction activities on site or in the vicinities, including land occupation.

The contractor is required to strengthen safety management, especially in

regard to the use of flammables, explosives, toxic and corrosive substances.

Before the start of construction, the contractor shall submit to the independent

construction supervision agency an emergency preparedness and response plan.

Environmental Protection

The contractor shall comply with all relevant laws and regulations on

environmental protection, and will take precautionary measures to minimize any

potential impact on the environment. It will be responsible for restoring and

rehabilitating the environment to its original state at its own costs. An

environmental management plan (EMP) with mitigation measures will be

prepared and submitted to the construction supervision agency for approval

before the commencement of construction.

The contractor will treat and dispose its construction wastewater, sewage

from workers’ camps and solid wastes properly so as not to cause any damage

to the environment, drinking water sources and public health. The disposal of

spoils and solid wastes shall not obstruct flood ways and risk public safety. All

slopes shall be protected with retention walls, proper drainage systems and

vegetation to avoid geological hazards. Noise, dust, air emissions, wastewater

and waste oils will be controlled to minimize annoyance to local communities.

Natural and Cultural Relics

All physical and cultural relics discovered at the construction sites are

owned by the state. The contractor will report any such discoveries immediately

to the local relics protection authority and in the meantime immediately inform

the construction supervision agency. The contractor shall take effective

measures to protect the unearthed physical and cultural relics. The contractor


3

will be held responsible for any loss of damage to the discovered relics, and

prosecuted for any delayed and fraudulent reporting.

2) Pollution control measures proposed by Technical Report (2007) of

Monitoring for the Project

Spoil Disposal: Sixty five spoil disposal sites have been located

throughout the Project construction area for the disposal of a net total (after uses

for fill) of 2.2115 million m3 of excavated spoil. The SEPP provides a detailed

analysis of all erosion sources as mitigation measures to prevent or control

them. It includes setting principles and erosion control prescriptions for spoil

dumps. These have been incorporated into the EMP.

Erosion Damage: Erosion potential from all construction sites, including

preparation of resettlement areas and road making, was estimated at about

75,000 m3. A comprehensive Soil Erosion Prevention Report (SEPR) had been

prepared. It provides a detailed analysis of all erosion sources with mitigation

measures to prevent or control them. It includes erosion control prescriptions for

borrow pits and quarries, dam and infrastructure construction, and construction

work areas and camps. These have also been incorporated into the EMP. To

date, contractors have taken measures to control soil erosion. Soil erosion

measures during construction include minimizing land surface disturbance and

exposure and use of settlement ponds. Upon completion of construction, all the

construction sites will be re-vegetated with trees and grasses.

Construction Wastewater: Wastewater produced during the construction

period come from washing aggregates, pouring and curing concrete, as well as

oil-containing wastewater from machinery repairs. The major pollutant in

construction wastewater is suspended solids. Settlement ponds are used to retain

the sediments in the construction wastewater before they are discharged into


4

rivers. The settlement ponds are cleaned when they are filled up with sediments.

Tires of construction vehicles are cleaned with spray water before they leave the

construction site. And the oil-water separators used for treating oil wastewaters.

Recycled water has been used to spray for dust control. All sludge was removed

from site.

Domestic Wastewater: Daily living wastewater produced by the

construction staff is about 440 m3. Deep latrines and seepage pits have been

installed in the each camp. After Project completion, the sites will be closed

only after waste has been effectively treated or removed, in order to minimize

pollution in the rivers.

Gaseous Air Pollution: Construction will consume about 8,925 tons of

diesels, releasing significant amounts of gaseous SOx, CO and NOx. The major

sources of air emissions are construction equipment and construction vehicles.

The vehicles delivering granular or fine materials to the sites were covered with

tarpaulin sheets. Vehicle speeds are controlled on construction sites. Equipment

was maintained to a high standard to ensure efficient running and fuel-burning.

High-horsepower equipment was installed with tail gas purifier. Atmospheric

monitoring was carried out during the construction period. A regular inspection

and certification system has been initiated to make sure that exhaust gases

complied with emission standards.

Dust: Construction sites will produce fugitive dust from material storage

areas, waste dump sites, concrete mixing and excavation sites. Material

stockpiles and concrete mixing equipment was equipped with dust shrouds. The

operators regularly maintained the shrouds to ensure their effective operation.

For both construction sites and construction roads, water spraying for the

suppression of dust was standard site management practice.


5

Noise: Noise was generated by construction machinery (excavators,

bulldozers, conveyers, concrete mixers) and transport vehicles. Works were

scheduled according to the noise rating of the machinery used and the distance

to sensitive receptors to achieve Emission Standard of Environment Noise for

Boundary of Construction (GB12523-2011). Noise impacts for transport

vehicles were reduced by attention to road surfaces near village areas and the

erection of temporary noise barriers.

Household refuse: In the five and half years of construction, a total of 6000

tons of waste were be generated. The accumulation of waste will have serious

impact on worker’s health. Thus, each construction camp was equipped with

dustbins, which will be regularly sprayed with pesticides, to reduce flies. In the

course of transporting domestic garbage and construction materials, loads were

sealed or covered, to avoid spillage en route.

Construction Wastes: Construction and demolition wastes could have

adverse impacts on surrounding environments. The solid wastes that could not

be collected at the waste dump, and could not discarded in a way which will

damage farmland or the surrounding environment. Solid waste were stored and

(2) Analysis of monitoring results

It can be known from table 4-1; the water quality of all the other

locations is up to Class II under GB3838-2002 Environmental Quality

Standard of Surface Water, except Qingshuihai (the middle spot of

Qingshuihai, Haiwei and Maichong) and Tabizi Spring.

In accordance with the water quality monitoring data of each

location during the environmental assessment phase subject to the

Written Report of the Project, and water quality monitoring data of 2012

provided by Xundian Environment Protection Bureau towards each

location in October 2012, and data of this phase, work out the water

quality conditions of each location before construction period, during

construction, and after the construction, all of which are shown in Table

By comparing the water quality conditions before construction (the

year of 2006, 2007) and during construction (2012), it can be concluded

that the water quality of Qingshuihai Reservoir maintains at Class II both

before and after construction; the water quality of Xintianhe Reservoir

maintains at Class III, the water quality of Banqiaohe Reservoir remains

at Class IV, and the water quality of Tabizi Spring changes from Class V

into Class III. It can be easily seen that the construction of the project

exerts no influences on the water quality of each location; in adverse, due

to the implementation of the construction, the impact of non-point source

pollution on the water quality of Tabizi Spring has decreased, so as to

make the water quality of Tabizi Spring turns into Class III in 2012.


27

Up to June 2013, the Project enters into completion phase. It can be

known by a comparison of the water quality before construction and after

construction that except for the change from Class II into Class III in

Qingshuihai Reservoir, and no water sample collected owning to

consecutive drought in Xinhetian Reservoir, water quality at the rest four

locations have improved , namely, water quality Class of Jinzhongshan

Reservoir, Shiqiaohe Reservoir , Tabizi Spring, and Banqiaohe Reservoir

all have turned into Class II from Class IV, Class III, Class III and Class

IV respectively.

Main reasons of the above are: catchment area of these reservoirs is

relatively small; the water quality is easily to be effected by the rainfall in

dry and rainy seasons, and rainy season didn’t come when the monitoring

was conducted in 2005, drought and little rainfall in 2012, while the

rainfall during the monitoring period in 2013 is sufficient. Since the water

source of Tabizi Spring is groundwater, and the water quality has little to

do with the rainfall, the water quality of 2013 varied little from that of

2012. It can be seen from the comparisons over the years that the

implementation of the project exerts little impacts on the water quality of

the surrounding surface water.

During construction period of the Project, wastewater treatment

measures have been taken at each site and camp to avoid impacts on the

surrounding surface water, so the water quality of the surrounding surface

water maintains stable.

Meanwhile, it can be inferred from Table 5-2 that the current water

quality of Qingshuihai reservoir after construction is worse than that

before construction, which now is Class III. The major reasons are: Since

December, 2012, Qingshuihai Reservoir started to receive water from

banqiaohe Reservoir, Xintianhe Reservoir, Shibanqiaohe Reservoir and

Tabizi Spring, entered into primary impoundment period, for which the


28

water body is in a process of blending, the water quality needs a

stabilization-oriented process. At the same time, due to the reservoir

capacity of Qingshuihai Reservoir, less vibration of water quality resulted

from rainfall. As a result, the influences of dry and rainy seasons on the

water quality of Qingshuihai Reservoir are relatively small than other

water sources.

In conclusion, the implementation of this project has exerted little

influences on the surface water; the decrease of water quality has been

caused by the water quality of the upstream after the water diversion

project started to work.

4.2 Clean-ups of the camps upon completion of the construction

By June 30, 2013, the construction of the project has been completed,

all contractors removed. There leaves administrative staff who are

responsible for collecting data in construction sites, namely 1#

construction camp of Banqiaohe, 2# construction camp of Shiqiaohe,

Qingshuihai section next to 6# Maichong tunnel entrance, distribution

gate of 23# Tongxin Reservior, 24# Jinzhongshan Reservior) while other

construction sites have all be removed.

Based on the conditions of site survey, most of the removed camps

have cleared up and smoothed the temporary lands that were occupied but

have not greened and restore them for farming; only the lands of 22#

construction camps of Gegentang Tunnel exit and Yangtianchong open

channel have been returned for farming. The four camps, 13#, 15#, 18#,

20# did not cleared up the sites when removed, which exerted certain

influences on the environment.

The personnel of Qingshuihai Reservoir beside Haiwei Village did

not remove the camp buildings after removal. As the reservoir water of

Qingshuihai is not intensive owing to many years of drought, it will

submerge the remaining buildings and have certain impact on the water

quality of Qingshuihai when the water storage is increased.

After the removal, the seven construction camps (namely, 8#, 9#,

10#, 13#, 15#, 18#,20# ) did not clear up the solid wastes generated

during the construction period, which polluted the environment.

5. Conclusion and recommendation

5.1Conclusion

（1）Monitoring of water quality

As of June 30, 2013, the environment monitoring during

construction period of Qingshuihai water supply project has been

implemented for half and five years. Project engineering construction in

the current monitoring has been completed and this monitoring is

conducted focusing on the environment of surface water.

Most contractors well kept their promise of protecting environment

during construction period, and mitigation measures of environmental

protection and environment monitoring measures have been carried out

effectively. The surface water beside most construction sites was not

influenced by the construction and water quality is up to the Class II

under GB3838-2002 Environmental Quality Standard of Surface Water.

The reasons why the water quality of Qingshuihai reservoir

decreased from II before the construction to III are mainly as follows:

factors such as large amounts of overland runoff in rainy seasons and

unstable water quality in the primary water storage period.

（2）Recovery of temporary occupied lands of construction camps

upon completion of the construction

The project has been completed and contractors have all removed

from the construction sites. Most temporary lands of camps have been

cleared up when contractors removed. However, some camps (namely, 8#,

9#, 10#, 13#, 15#, 18#, 20#) have not been dealt with when the

contractors removed and there left solid wastes and household refuse


32

generated during the construction period, which exerts some impacts on

the around environment.

5.2 Recommendation

Subject to the site survey of each construction camp by the research

group and taking the environment monitoring results into consideration,

the following mitigation measures about the Project (from August, 2012

to June, 2013 ) are put forward:

（1）When all site offices are removed, it is required that temporary

occupied lands should be cleared up and restored for farming;

（2）The camps that have been removed and cleared up the sites

shall recover or return ecological vegetation of the temporary

construction lands for farming;

（3）The camps that have been removed but not cleared up the sites,

shall clear up and remove the solid wastes among which building wastes

shall be assigned to a qualified unit for removal; at the same time,

leveling the lands and ecological recovery shall be conducted.

（ 4）Construct side slope for all the built roads to reinforce

protection, and plant vegetation in planting slope when necessary to

prevent natural disaster such as mud and rock flow and landslide, etc.

（5）Pay close attention to the landform evolution around the

subsidence area of Dapingdi Tunnel Exit to prevent the expansion of

subsidence area as the result of continual construction which shall

aggravate the impacts. When the condition is allowed, it is desirable to

backfill the subsidence area as soon as possible and recovery the

vegetation of this area.
