Guidelines of Water Application

A. APPLICATION OF WATER SOURCE

The owners or the developers, through the consultants appointed by them, can submit the application to SYABAS by forwarding the following documents :

Letters of Appointment from the owners or developers and confirmation letters as registered consultant engineers with SYABAS;  

Water demand calculations in accordance with SYABAS' requirements stipulated in Table 1;

A copy of approval letter and Development Order from the relevant Local Authority;  

Key and Location Plans;  

Site Plans (1 : 10, 000) preferably using the Street Directory Maps and certified by a professional Land Surveyor;

Site plans with contour lines at 5 m interval and proposed platform levels of the proposed development (in meter or feet ODL).  

For daily demand less than 225,000 litres, these documents shall be submitted directly to the respective district office of SYABAS.

 

B. SUBMISSION FOR THE CONCEPTUAL DESIGNS

For daily demand exceeding 4.5 million liters and is to be developed phase by phase, the conceptual designs for the whole areas must be submitted to SYABAS.

Two (2) sets of Conceptual Design Report containing the following information shall be submitted:

General descriptions of the Project;

Water demand schedules in accordance with the types of development for the whole areas;

Water demand schedules in accordance to each phase and type of development, together with the year in which each phase is to be developed;

Supply zone from the reservoir for each phase must be indicated;

Hydraulic calculations for peak flow from the source to reservoirs, incoming mains, the levels and sizes of suction tanks, pumping mains, the levels and sizes of reservoirs and the residual heads in the pipes for a particular supplied zone;

Brief descriptions and schematic diagrams which showed the whole water supply systems including nodes, outflow from each node, lengths and sizes of pipes.

Note: For factories where the water demands cannot be ascertained, use 75, 000 lpd (16, 500 gpd) for each hectare of land; If building categories/demands do not appear in Table 1, please liaise with the Planning and Development Department for further information.

 

C. SUBMISSION FOR THE DETAILED DESIGN OF WATER SUPPLY SYSTEMS

The detailed design shall be in accordance with each phase of development.

Three (3) sets of report for the detailed design of water supply systems containing the following information :

General descriptions of each phase;

Water demand schedules in accordance with the types of development, peak, average and fire flows design calculations, pumping systems, levels and sizes of the reservoirs calculations;

Detailed layout plans showing main reticulations and coloured according to the types and sizes of pipes, locations; types; sizes; BWL / TWL of reservoirs and suction tanks together with pump houses;

Detailed layout plans showing the locations, side and top elevations, cross-section of inflow; outflow; overflow and discharge pipes, valve locations, level measuring instruments, air-circulation systems and ladders for reservoirs together with security fencing;

For hydraulic calculations of reticulation systems, the following information shall be provided:

a) Pipe Details;

b) Node Details

A copy of SYABAS' Standard Specification shall be attached;

The Consultant must submit to the Planning and Development Department of SYABAS, in the form of CD-R, all drawings related to water supply systems for a particular development pending approval. The said drawings shall include the following:

Layout Plans for Reticulation Systems;

Layout Plans for Reservoirs, Suction Tanks and Pump Houses;

Detailed of Reservoirs, Suction Tanks and Pump Houses;

Layout Plans for incoming pipe works including sectional views;

Standard Drawings;

Data used in hydraulic calculations of reticulation systems.

The Professional Engineers appointed by the owners or the developers shall certify all drawings, calculations and work specification and shall be registered with SYABAS.

 

D. SUBMISSION FOR THE DESIGN OF PUMPING SYSTEMS AND BREAK PRESSURE TANKS

Two (2) sets of the design of pumping systems shall be submitted to the Mechanical and Electrical Department of SYABAS within four (4) months after the detailed design of reticulation systems had been approved. One (1) copy shall be submitted to the Planning and Development Department of SYABAS.

Each proposed design and installation must consist of:

Pumping systems design calculations;

Pumping mains design calculations;

Break pressure tanks design calculations;

Detailed drawing of pumping systems, i.e. layout for pump houses, suction tanks and reservoirs;

Data and technical information on all mechanical equipment;

List of spare parts.

The design and calculation reports shall be prepared by the Mechanical Consultant and certified by a registered Professional Mechanical Engineer;

Prior approval from the Mechanical and Electrical Department of SYABAS shall be obtained before commencing any work on site;

One (1) set of electrical wiring systems for pump houses shall be submitted to the Mechanical and Electrical Department of SYABAS.

 

E. SUBMISSION OF TELEMETRY SYSTEM

Telemetry system is needed for pumping system that exceeds 2.5 million lpd or 4.5 million liters for reservoir.

The telemetry system must be similiar to the current system as at SYABAS. For updated information on this system, please liaise with the Telemetry Unit of SYABAS.

One (1) complete set of the telemetry system must be submitted to the Telemetry Unit of SYABAS and the installation shall be done by SYABAS.
