Chapter 1 outlines the problem
statement, objective and scope of work. The background of the study area
is described in Chapter 2. This chapter presents the location,
topography, climate and landuse of the study area. Chapter 3 reviews
previous studies carried out in the study area by other consultants.
Chapter 4 reports the data collection works being carried out to acquire
the data. Chapter 5 describes the existing drainage system. This chapter
highlights the present condition and the evaluation of the existing

Background of Study
:
Bandar Bukit Kayu
Hitam is Kedah's main border town on the Malaysia-Thailand Border. It is
managed under the jurisdiction of Majlis Daerah Kubang Pasu (MDKP). The
Department of Irrigation and Drainage, Kedah (DID Kedah) had receives
many reports and complaints from local residents and industrial
investors due to the flash flood problems. Flooding frequently occurs
since year 2006 and the latest occurred on 7th March 2012. A total
rainfall depth of 168 mm over a 2 hours period has been recorded at
Bukit Kayu Hitam Rainfall Station (MADA’s Station) for this event. It
involves the upstream area of the catchment which includes Black Forest
Golf & Country Club and its surrounding area.
DID Kedah suspected that the
overflow from the detention pond located inside golf club cannot cater
to the peak flow from the rainfall event, hence cause flooding further
downstream. As a consequence, this area is rather flood prone especially
during heavy downpour. In order to solve the flooding issue, DID Kedah
requires the service of an established consultant who is familiar with
stormwater design in Malaysia using the Urban Stormwater Management
Manual for Malaysia (MSMA) by the Department of Irrigation and Drainage
(DID) Malaysia, to conduct feasibility study and subsequently produce
the mitigation plan to overcome the problem.
It is on such approaches that
The Department of Irrigation and Drainage, Kedah (DID Kedah) is inviting
Perunding Pinang Sdn. Bhd. (hereafter refers to as the consultant) to
prepare Kajian Kejuruteraan dan Rekabentuk Terperinci Bagi Rancangan
Tebatan Banjir, Bukit Kayu Hitam, Kedah Darul Aman. This four month
study was awarded on 1st October 2012.
Objectives of Study :
The primary goal of this work is
to implement stormwater management system so that the impact of
urbanization on stormwater environment that affects the livelihood of
urban community could be reduced tremendously through eco-friendly
stormwater management facilities. In order to achieve this, the work
shall meet the specific objectives of urban stormwater management are as
follows;
i. To implement stormwater
facilities that give up to date solution for the flooding, drainage and
stormwater management problems in the existing built-up areas in order
to reduce the adverse effects of flooding on people and property and to
protect the existing and proposed development by implementation of an
integrated stormwater management by providing an appropriate level of
affordable flood protection to community expectations.
ii. To upgrade the effectiveness
of the existing stormwater infrastructure network within the project
area in a way that meets the needs of the community and where possible,
by providing and maintaining stormwater management infrastructure at an
acceptable quality of service, taking into account environmental effects
and public expectations.
iii. To provide control
structures against excessive sediment and floatable rubbish in
watercourses to acceptable levels by managing the catchment activities
using at source control measures to prevent any acceleration of the rate
of erosion from generated from developed areas, on land and in stream
channels.
iv. To construct stormwater
collection and conveyance systems from a catchment to its receiving
waters that curtail minimal impact to the surrounding areas by managing
and improving the quality of stormwater runoff from urbanized catchment
and its pollution loads in order to reduce the adverse effects of
non-point source contamination on the receiving water environment and by
eliminate point source pollutions discharges where possible to
stormwater systems and receiving water in order to reduce the adverse
effects of point-source contamination.
Scope of Work :
Pursuant to the objectives as
outlined above, the scope of work is drawn to describe the structured
mechanism on how the project should be executed, as well as providing
details on the issues and the associated areas to be addressed. The
scope of work covers various components with activities ranging from
data collection, identification of issues, planning and preparation of
supporting documents. The scope of works shall include but not be
confined to the following:
i. Engineering Surveys and
Geotechnical Investigation
ii. Hydrological and Hydraulic
Analysis
iii. Detailed Planning and
Design
iv. Channel/Pond Bank and Slope
Protection Works
v. Working Drawings and Tender
Documents
vi. Drainage/Pond/River Reserve
and Land Acquisition Plans
vii. Operation and Maintenance
Manual
viii. Use of Local Materials
ix. Training for JPS Staff
