Notwithstanding these efforts, no warranty or guarantee, express, implied or statutory is made as to the accuracy, reliability, suitability or results of the methods or recommendations.

The use of this Manual requires professional interpretation and judgment. Appropriate design procedures and assessment must be applied, to suit the particular circumstances under consideration. The government shall have no liability or responsibility to the user or any other person or entity with respect to any liability, loss or damage caused or alleged to be caused, directly or indirectly, by the adoption and use of the methods and recommendations of this Manual, including but not limited to, any interruption of service, loss of business or anticipatory profits, or consequential damages resulting from the use of this Manual.

The manual became invaluable references for both practising as well as officers newly posted to an unfamiliar engineering environment. The challenges are also wider covering issues of environment and its sustainability.

Recognising this, the Department decided that it is timely for the DID Manual be reviewed and updated. Continuing the spirit of our predecessors, this Manual is not only about the fundamentals of related engineering knowledge but also based on the concept of sharing experience and knowledge of practising engineers. This new version now includes the latest standards and practices, technologies, best engineering practices that are applicable and useful for the country.

Within each Volume is a wide range of related topics including topics on future concerns that should put on record our care for the future generations. This DID Manual is developed through contributions from nearly professionals from the Government as well as private sectors who are very experienced and experts in their respective fields.

It has not been an easy exercise and the success in publishing this is the results of hard work and tenacity of all those involved.

The Manual has been written to serve as a source of information and to provide guidance and reference pertaining to the latest information, knowledge and best practices for DID engineers and personnel.

The Manual would enable new DID engineers and personnel to have a jump-start in carrying out their duties. This is one of the many initiatives undertaken by DID to improve its delivery system and to achieve the mission of the Department in providing an efficient and effective service.

This Manual will also be useful reference for non-DID Engineers, other non-engineering professionals, Contractors, Consultants, the Academia, Developers and students involved and interested in water-related development and management.


Just as it was before, this DID Manual is, in a way, a record of the history of engineering knowledge and development in the water and water resources engineering applications in Malaysia. There are just too many to name and congratulate individually, all those involved in preparing this Manual. Most of them are my fellow professionals and well-respected within the profession.

I wish to record my sincere thanks and appreciation to all of them and I am confident that their contributions will be truly appreciated by the readers for many years to come. Lim Chow Hock, Ir.

Mixed-flow and axialflow are most commonly used for both irrigation pumping and flood control. Paddy field irrigation pump operates continuously during the planting season while flood drainage pump operates intermittently whenever the inflow water is excessive and during flood.

Lately, Archimedean screw pumps have also been installed in view of its capability in handling large volume of water over a wide range of flow rates without clogging. However, civil works is expected to be expensive as it takes up substantial floor space on installation. Pumps of various design configurations are as shown in Figures 1. Hitherto, more compact and integral electrical submersible pump-sets have gained popularity over the conventional long-shaft-driven pumps in view of its simplicity in installation work and it needs minimal superstructure.

Construction of the pumping station can either be wet pit or dry pit, but wet-pit installation is commonly adopted. Typical arrangement of the wet-pit and dry-pit installation pumping station is as shown in Fig.

Attempts have been made to incorporate the state-of-the-art technology in control and monitoring to the newly built pumping stations for remote monitoring and control. They are mobilized either to supplement water for irrigation or to dewater in flooded area. Hydraulic submersible pump-sets are commonly used as they are easy to handle, operate and install, and require minimum civil work in installation.

Normally they are skid-mounted as shown in Figures 1. As an alternative, portable electrical pump-sets complete with independent canopy-type generating set have been included for its quietness in operation. However, a competent person should be assigned in operating the generating-set. They are subjected to high wearing rate due to the abrasiveness of the solid material being handled, they are either rubber-lined or double-walled, or pinahan with wear resistant material such as Ni-Hard Martensitic kewanyan irons.


They are made very rugged and simple with large clearances. Pump design is of volute, single stage, single-suction type and has a closed single curvature, non-clogging, overhung, radial curved-vane runner.

Stuffing box, which provides a seal around the runner shaft when it enters the pump casing, is flushed with clear water continually in preventing sand from getting into it. Table below shows types of pumps for various specific speeds. Yes, at higher Ns. Pumps of low specific speed will pindaham a relatively flat curve capacity pindauan high specific speed pumps will exhibit a steeper curve.

The system pindahzn curve can pindxhan represented graphically by combining the static head and system friction head as shown below. Pumps may be arranged to operate independently with individual delivery system or to operate in parallel in a single delivery pipeline. However, when operated in parallel, because of the additional resistance incurred it is unlikely to achieve the theoretical increase in flow rate.

Where kdwangan quantities of discharge are required at high heads, multiple pumps in series may be used. However, such system is rarely common in DID application. A control based on water level in the pump sump or in the discharge canal is commonly used as a control constant for irrigation and drainage applications.

The automatic level-responsive kewnagan control is designed for a pump-up mode in filling up the pinfahan to the designed full supply level for irrigation purpose or b pump-down mode in keeping the sump water level under a certain level for flood control. For reliable automatic control, especially in land drainage pumping station, due consideration shall be given to the consequences of the failure of any station components in the design stage.

All practical provisions should be made for continual station operation under such component failure conditions. Critical components may be provided in duplicate as standby and additional pumping unit shall be provided.

For larger pumping stations, standby generating-set may be provided as an alternative source of power supply in the event of power outage. Monitoring features shall include i status indication of plant operating conditions ii alarm monitoring of plant parameters for malfunctioning and out-of-limit conditions and iii automatic protective shutdown devices for faulty operating conditions and set-limit conditions.

Alternating pump starting will help in equalizing pump wear and minimizing the starting frequency of each particular pump.

To maintain the flexibility in operation and to adopt piindahan demand variation, preferably sufficient number of same capacity pumping unit should be provided. Considering reserve capacity of the pumping installation, sometimes an additional same capacity unit may be installed as standby to cater for emergency use particularly for storm water pumping installations.
