TERMS OF REFERENCE FOR PELAN INDUK SISTEM SALIRAN (MASTERPLAN) BAGI PENGURUSAN AIR RIBUT (STORMWATER) DI DAERAH KUALA LANGAT, DARUL EHSAN

1.0 INTRODUCTION

The planning of stormwater systems has moved significantly away from traditional concrete lined channels emanating from the depression era. Considerable use has been made of retarding basins to mitigate increased flood peaks due to urbanisation and massive land opening for development activities. Grassed floodways have largely replaced concrete channels to slow flow velocities and provide greater visual appeal and passive recreation areas. Additionally, over recent years there has been an attempt to intercept a range of non-point source pollutants including agricultural and domestic waste, general litter, sediment, and nutrients etc., utilising stormwater Best Management Practices (BMPs) including gross pollutant traps, water quality and quantity control ponds, swales and rain water harvesting system. There is also an increasing awareness of the ecological values of watercourses and the need to maintain and enhance these values.

An effective water quantity and quality management strategy for area involves managing good development practices as well as construction and post- construction activities. Under these conditions, control of water quantity and quality shall be undertaken at source, in addition to stormwater treatment prior to discharge to receiving water. The water quantity and quality management relating to construction activities involves the use of erosion and sediment control techniques during the construction phase. The general management philosophy involves the minimisation of erosion by diverting runoff from undisturbed catchments around work areas, rapidly revegetating disturbed areas, and trapping eroded sediment from disturbed sites.

For the post-development phase, the water quality enhancement can be achieved by controlling the pollution loads at source to minimise the amount of pollution entering the drainage system. It is based on the premise that it is generally easier and more cost-effective to control pollution at source rather than removing pollution from within the drainage system. Further, stormwater treatment measures alone may not be able to reduce pollutants to pre-development levels. Two broad categories of source control exist, namely physical techniques and education. Treatment measures of stormwater runoff shall be identified at established urban areas to remove pollutants in order to enhance the quality of discharges to receiving waters. Ranges of stormwater BMPs are available which aim to improve the quantity and quality of post development LAMPIRAN D stormwater runoff. There are two major types of BMPs, namely retention systems (e.g. wet basins, construction wetlands etc.) and infiltration systems (e.g. infiltration basins, trenches etc.).

Jabatan Pengairan Dan Saliran Negeri Selangor requires engineering consultancy services to prepare a Pelan Induk Sistem Saliran Bagi Pengurusan Air Ribut Untuk Mengatasi Banjir Di Daerah Kuala Langat, Selangor Darul Ehsan.

2.0 BACKGROUND

The Kuala Langat District is a district of Selangor, . It is situated in the southwestern part of Selangor. It covers an area of 858 square kilometres, and had a population of 213,876 at the 2010 Census (exclude foreign). It is bordered by the district of and Petaling to the north and to the east. Its southern border forms part of Selangor's border with the state of Negeri Sembilan. The Strait of Malacca forms its western border. Among the major towns in Kuala Langat are , , Teluk Datok, and an island .

The has a total catchment area of approximately 1815 km2. It lies within latitudes 2o 40’M 152” N to 3o 16’M 15” and longitudes 101o 19’M 20” E to 102o 1’M 10” E. The catchment is illustrated in Figure 3.2. The main river course length is about 141 km mostly situated around 40 km east of Kuala Lumpur. There are two reservoirs, the Langat Reservoir and the Reservoir respectively. The Langat Reservoir, built in 1981 has a catchment area of 54 km2 while the Semenyih Reservoir, built in 1982 with the purpose to supply domestic and industrial water has a catchment area of 41 km2. For the Langat Reservoir, it is also used to generate power supply at moderate capacity for the population within the Langat Valley.

Insufficient or inefficeint drainage system, no proper discharge outlets to the main river system, dilapilated condition of existing drain and incorrect drainage gradient cause the flash flooding occur regularly during heavy downpour.

In order to alleviate the flooding problems within the area, Jabatan Pengairan dan Saliran Selangor requires engineering consultancy services for preparation of stormwater management and drainage master plan study for Kuala Langat district The study proposed by the consultant has to take into consideration the implementation of Urban Stormwater Mangement Manual (MSMA).

The essential features of each alternative such as size, costs, benefits, and positive and negative attributes should be compared in summary form for presentation to DID for decision-making.

4.7 Development of Stormwater Management Master Plan

A Stormwater Management Plan (SMP) can be described as a framework for action. The Plan is intended to provide direction for stormwater management within a catchment and/or sub-catchments. The Plan shall provide a framework for achieving this aim by identifying sustainable stormwater programs and solutions which can be implemented as a cooperative approach by stormwater managers and the stakeholders. The primary outcome of the stormwater management planning is to propose management actions which are tailored to the identified stormwater issues for the existing and future development.

A SMP shall be prepared, by incorporating the integrated stormwater management approaches, which shall comprise drainage system plans, longitudinal sections, detailed of proposed structures and stormwater quality LAMPIRAN D improvement devices, supporting hydrological and hydraulic data and calculations, and other information as necessary to adequately define the components of Master Plan and the basis of its analysis and conceptual/schematic design.

Structural and non-structural BMPs are recognized as the most effective and practical measures to reduce or prevent pollutants from reaching water bodies and to control the quantity of runoff from a site. In preparation of the Master Plan, the Consultant shall examine both structural and non-structural control measures. The Consultant shall identify "at source" controls to be recommended in the study area. The consultant shall propose drainage systems or other physical structures, such as detention and retention, infiltration basins, pretreatment devices, and swales, to manage stormwater.

Natural streams and rivers within study areas shall be delineated for conservation with recommended reserve widths. The objectives of "at-source" controls will be to enable river cross-sections to be maintained without the need for widening to cater for increased discharge due to the development concerned. Lining the stream/river banks should only be proposed for the purpose of slope protection at specific locations, where necessary. Besides technical considerations, the Consultant shall take into account other constraints such as social and land problems in the preparation of the Master Plan.

The Consultant shall also develop the stormwater utilization plan, where the plan shall outline details of rainwater/stormwater utilization to promote the resource for non- potable uses specific for the catchment. The plan when implemented shall contribute to reduce water demand pressures on the public water supply system. The plan shall identify the type and location of stormwater storage facilities, use categories of stormwater sources and the procedures to be adhered for such usage.

The Consultant shall also prepare proposals for the landscaping, beautification and recreational development of the drainage corridors, bund reserves as well as reserves for other drainage and stormwater facilities and associated works within the study area. The plan shall include a cost estimate of all the proposed works.

4.8 Cost Estimates and Benefits

The Consultant shall prepare and submit cost estimates for the implementation of all the proposed works including a qualitative and quantitative analysis of benefits. The scope of work under this section includes preparation of budget estimates for effective stormwater management and the identification of sources of income to cover the construction costs as recommended in this study. Expenses to be studied include LAMPIRAN D consultancy fees, capital expenditures, land acquisition, O&M expenses and administration costs.

4.9 Prepare Plan Implementation Program

The questions of when the plan elements are to be implemented, who has the primary responsibility for implementing them, and how the implementation is to be carried out, including financing, should be addressed by the Consultant. For plans prepared on a catchment basis, implementation may need to be carried out on a jurisdictional or sectoral basis by a number of different Local Authorities. The number of implementers can vary widely depending on the size and complexity of the SMP.

The elements of the recommended plan should be prioritised into relative order and the expected time for implementation of each element stated. Prioritisation should be determined based on the following factors: i. the operation of certain components of the stormwater management system may be dependent on the existence of other components;

ii. higher priority should be given to those elements of the recommended plan that are likely to provide the greatest benefit in relation to the stated objectives; iii. some elements may not be implemented if action is not taken immediately or at some other appropriate time to capitalise on special circumstances or opportunities.

Special opportunities that could have a bearing on the implementation of a plan, such as possible sources of financing, should be identified.

4.10 Training and Briefings

During the course of the Services, DID may attach one or more counter-part engineers for on-the-job training with the Consultant for this Study and the Consultant shall accommodate this request.
