The role of a tidal control gate is to regulate and prevent saline water (sea water) from entering upstream river areas, which can sometimes flow up to 10 kilometers depending on the river's water level, potentially affecting water use for agriculture. Additionally, tidal control gates also function to manage and discharge excess water that could cause flooding in the surrounding areas directly into the sea.

The operation of tidal control gates can be carried out in several ways. Here are some of the methods implemented at JPS:

i. Manual (hand wheel)
This method uses human effort, where the operator manually turns a 'hand wheel' on a 'gearbox' to open and close the tidal control gate.

ii. Semi-Auto (push button)
In this method, the operator must be on-site at the tidal control gate to open and close it by pressing a push button switch.

iii. Automation
The gate is controlled automatically through a pre-set program.

iv. Supervisory Control and Data Acquisition (SCADA)
The gate is controlled both automatically and remotely from a distance through a pre-set program.

The role of a dual-function control gate is to regulate water levels for both agricultural irrigation systems and flood drainage systems.

For agricultural irrigation, the control gate is closed to store water, especially during the dry season, and opened to release water for crop irrigation as needed. For flood drainage, the gate is opened to release water downstream. If the water level downstream is high, the control gate is kept closed to prevent water from flowing upstream.

A drainage pump house serves to transfer water from upstream areas to downstream areas to prevent flooding when water reaches flood levels.

A drainage pump house operates automatically when the water level in the reservoir or catchment reaches a specified threshold.

An irrigation pump house provides appropriately sized pumps based on the area of crops in a location. The pumps operate to supply water according to the agricultural needs of the area.

An irrigation pump house operates to supply water according to agricultural needs at a specific location, manually and seasonally.

Usually, portable pumps are installed when a flood occurs. However, in areas that frequently experience flooding, portable pumps are installed permanently for a longer period to reduce the impact of floods.

The Environmentally Friendly Drainage Manual (MSMA) is a guideline for engineers to plan urban drainage infrastructure using the concept of quantity and quality control at the source. This method is introduced to prevent flash floods, mud floods, and river pollution.

The MSMA document can be obtained for free by downloading it from the following web link: https://www.water.gov.my/jps/resources/PDF/MSMA2ndEdition_august_2012.pdf

ESCP is an Erosion and Sediment Control Plan implemented before land works begin. It aims to prevent soil erosion at construction sites and control sediment deposition into rivers and water bodies.

ESCP is required for all land works exceeding 1 hectare. For projects subject to an Environmental Impact Assessment (EIA), the ESCP must be prepared by a Professional Engineer with a Practice Certificate (PEPC) and a Certified Professional in Erosion and Sediment Control (CPESC) or equivalent.

It is recommended to construct quantity control structures for managing stormwater as follows:

i. Development Area < 1 hectare – Individual On-Site Detention Pond (OSD)
ii. Development Area 1 - 5 hectares – On-Site Detention Pond (OSD)
iii. Development Area 5 - 10 hectares – Dry Detention Pond
iv. Development Area > 10 hectares – Wet Detention Pond

The BMPs recommended in MSMA for quality control after development completion include trash traps, bioretention systems, swales, wetlands, and detention ponds

The design capacity requirements for flood detention ponds consider a major drainage system with a 100-year Average Recurrence Interval (ARI).

All BMPs for sediment control should be designed to capture 90% of sediment discharged from the construction site. Sediment traps should be designed with a 10-year ARI and detention capacity as specified in Table 10 of MS 2526-12:2014 Part 12 Erosion and Sediment Control.

Rainwater Harvesting (RWH) involves collecting rainwater from building rooftops or other specially constructed structures. The benefits of rainwater harvesting include:

i. Utilizing water resources towards sustainable development, especially in urban areas. This system can be applied for domestic, industrial, commercial, and agricultural uses.

ii. Providing an alternative water source for non-potable uses such as toilets and firefighting, which can help reduce treated water bills.

iii. Improving river management by reducing the flow rate to drainage systems, thereby decreasing erosion rates.

The Environmentally Friendly Drainage Master Plan (PISMA) is a master plan for drainage in a specific area that includes an analysis of the drainage system considering both existing and future land use. PISMA contains a drainage master plan for quantity and quality control in stormwater management. It also includes recommendations for addressing flash flood issues and stormwater pollution.

Maintenance of On-Site Detention (OSD) and detention ponds falls under either JPS (Department of Irrigation and Drainage) or PBT (Local Authorities), depending on the determination of the state government.

Companies interested in participating in JPS tenders/quotations must ensure they are registered with the Construction Industry Development Board Malaysia (CIDB) and have obtained the Contractor Registration Certificate (PPK) and the Government Procurement Certificate (SPKK) in the relevant grade, category, and specialization, as well as the Bumiputera Status Certificate (STB) issued by the Contractor Service Centre, Ministry of Entrepreneur Development and Cooperatives, if applicable. Companies should also ensure that these registration certificates are still valid.

Common specializations required for drainage and irrigation works include CE21, CE06, and CE40. Companies can check tender advertisements on the MyProcurement website - https://myprocurement.treasury.gov.my/ and the official website of the Department of Irrigation and Drainage Malaysia - https://www.water.gov.my/.

Flash flood is defined as a rapid rise in water levels caused by intense rainfall, resulting in flooding within a short period.

Short-Term: Carry out cleaning work for blocked drainage in the affected areas.

Long-Term: Implement Flood Mitigation Plan (RTB) projects to reduce flooding problems.

Information and monitoring of rainfall warnings and current water levels can be accessed via http://publicinfobanjir.water.gov.my.

The Flood Hazard Map is a map created using hydrodynamic modeling that shows the extent and depth of flooding based on specific recurrence intervals (ARI). In the context of JPS, this map is a key resource for assessing and translating flood risk when developing policies and strategies for flood management. It helps in:

i. Identifying potential flood mitigation project locations.

ii. Recognizing areas and locations affected by floods across the country.

iii. Estimating the impact and evaluating flood damage.

iv. Raising awareness and preparedness among residents to reduce flood losses.

v. Assessing and selecting flood evacuation centers.

The uses of the Flood Hazard Map include:

i. Planning flood mitigation structures.

ii. Analyzing flood hazard maps by integrating information from the Department of Statistics to determine the number of residents affected by flooding.

iii. Assisting the Department of Urban and Rural Planning in developing development plans through the National Structure Plan.

iv. Creating flood evacuation maps.

v. Developing flood insurance index maps.

vi. Preparing flood risk maps.

The RTB project implements flood mitigation initiatives as part of JPS's efforts to reduce flood risk to residents.

Flood mitigation is a method for addressing flooding caused by river overflow, while urban drainage deals with flash floods in urban areas.

The guidelines applied for river sand mining applications are the "Guidelines for River Sand Extraction Amendments 2012."

The guidelines applied for any development applications involving rivers are the "Guidelines for Development Involving Rivers and River Reserves."

The scope of work involved in the JPS river conservation program includes:

i. Excavation work, including the removal of silt, deepening, and clearing obstructions, debris, solid waste, trees, and other materials in the river.

ii. Grass cutting and cleaning of riverbanks.

iii. Stabilization of riverbanks.

iv. Maintenance of immovable assets.

The public can apply to use river reserve land for agricultural purposes by submitting a letter of application along with the location details to the District and Land Office.

Yes, you can. The applicant must submit a request to JPS, and the road must be constructed according to JPS/JKR specifications.

The length of the coastline experiencing erosion throughout Malaysia is 1,347.6 km. The erosion is divided into three categories:

Category 1: Critical (erosion exceeding 4m per year) = 55.4 km

Category 2: Significant (erosion between 1m and 4m per year) = 375.9 km

Category 3: Not Serious (erosion less than 1m per year) = 916.3 km

The development setback limits in coastal areas according to the National Coastal Erosion Study (NCES) 2015 are:

i. For coastlines experiencing Category 1 erosion = 60m from Mean High Water Spring (MHWS)/High Water Line
ii. For coastlines experiencing Category 2 erosion = 30m from Mean High Water Spring (MHWS)/High Water Line
iii. For coastlines experiencing Category 3 erosion = 20m from Mean High Water Spring (MHWS)/High Water Line
iv. For coastlines with mangrove forests = 400m from the seaward edge of the mangrove forest (Development is not allowed if the mangrove forest area is gazetted as a permanent forest reserve under the National Forestry Act 1984)

Generally, sand mining activities are not permitted in areas located less than 1.5 km from the Mean Low Water Line or 10 meters in water depth measured from the Lowest Astronomical Tide, whichever is further from the shoreline.

Applications can be submitted in writing to the Director of the Management Services Division, Department of Irrigation and Drainage Malaysia or by email to uruspsm@water.gov.my.
