MSMA is a comprehensive manual issued by Department of Irrigation and Drainage (DID) Malaysia in 2000. It is a how-to-do-it guide on how Urban Drainage should be practiced in Malaysia. MSMA stands for “Manual Saliran Mesra Alam” (Manual for Environmentally friendly drainage).

According to Charles A. Doswell, a flash flood can be defined as an event where the rising water occurs during or a matter of a few hours after the associated rainfall. If the damaging water level increases occur more than a few hours after the rainfall, the event is considered to be a flood and not a flash flood.

DID in general appreciates information on the causes as well as sources of river pollution. However, DID is not the enforcement authority on pollution control. Please refer the problems to the Department of Environment (DOE) or the Natural Resources and Environment Board (NREB).

These information are published annually by our Hydrology and Water Resource Division which is located on the 9th Floor, Wisma Saberkas, Kuching. On-line information on rainfall and major river levels in the State are available at  https://ihydro.sarawak.gov.my/iHydro/en/index.jsp

DID is not responsible for your domestic or industrial water supply, DID is only responsible for irrigation water supply for the farmers. Please contact the relevant authorities such as Kuching Water Board (Kuching City), Sibu Water Board (Sibu Town), LAKU (Miri, Bintulu and Limbang) or the Public Works Department (for rural and other areas) who will bill you for your water supply.

Both DID and the appropriate local authority are responsible for drainage. In general the local authority is responsible for the construction and maintenance of the local drainage system which is mainly of secondary drains. DID Sarawk is responsible for the main trunk drains and the rivers which may flow within and outside the local authority areas.

Floodings caused by choked drains and culverts fall under the responsibility of the local authority. Floodings caused by overspilling of rivers due to inadequate capacity is normally the responsibility of DID.

You may contact our PRO, email jps@sarawak.gov.my or telephone 6082-243241.

The "Sarawak River Board" is responsible for the management of the Gazetted Rivers in the State, however DID is responsible in all engineering aspects.

The main Programmes are:
i.   Water Management and Implementation of Drainage and Irrigation Projects
ii.  Urban Flood Mitigation
iii. River and Coastal Engineering
iv. Hydrology and Water Resources
v.  Implementation of Rural Roads

DID Sarawak is a State Government Agency. However, we are answerable to both the State and Federal Government as we are allocated with both State and Federal Funds.

Please refer this matter to the appropriate local authority responsible for the maintenance of these drains.
