1 1.0 INTRODUCTION 2.0 SCOPE Page 1 of The objective of the manual is to have a standardized procedure of taking over water supply systems from developers by the districts. 1.2 To enable consultants and developers to know the procedures undertaken by SYABAS and what is expected of them. 1.3 To facilitate the process of taking over the completed water supply systems constructed by developers. 1.4 To ensure that completed water supply systems taken over are built according to the approved plan and is of good quality. 2.1 The manual covers the quality control during construction stage followed by the taking over processes for civil, mechanical & electrical and telemetry works as follows :- 3.0 GENERAL POLICY a) Taking over of External Permanent Water Supply System b) Quality Control of Internal Plumbing System c) Taking over of Mechanical & Electrical and Telemetry System 3.1 Role and Responsibility The role and responsibility of each party involved in the implementation of external water supply system is listed below:- i) Authority Given to SYABAS District a. Districts approve external plan submission for water demand less than 50,000 lpd within three (3) weeks. b. Districts approve all internal plumbing plan approval for buildings less than 6 storeys within three (3) weeks.

2 Page 2 of 6 c. Districts to oversee and monitor all construction works of all projects, irrespective of the size of development. d. Districts have the right to access, monitor, check and inspect all ongoing works based on approved plans executed by developers during construction stage, and upon satisfaction with the quality of works, take over the completed water supply systems. e. Districts are in-charge of operation and maintenance of the completed water supply system after taking over from developers. ii) Authority Given to SYABAS Development Department (H.Q.) a. Development Department approves plan submission on external water supply system for water demand more than 50,000 lpd within three (3) weeks. b. Development Department approves all internal plumbing plan approval for high rise buildings more than 6 storeys within three (3) weeks. c. All approved plans will be forwarded to the districts for supervision purpose. d. SYABAS development section will carry out surprise independent check for quality control based on approved plan at project site. iii) Role of SYBAS Audit Department (H.Q.) a. To ensure quality control, audit Department may carry out independent site auditing on water supply system of ongoing development projects built by developers and to check whether it complies to approved plans. iv) Role of SYABAS Committee on Standard, Material and Product (H.Q.) a. SYABAS Committee on Standard, Material and Product approve the use of materials and products for SYABAS water supply installations. b.

Developer is required to ensure no construction work shall commence without the water supply system plans already approved by SYABAS. b. To appoint Professional Engineer registered with Board of Engineers Malaysia from SYABAS recommended list of consultants who are familiar with SYABAS technical requirements on water supply system. (A list of consultants is available from SYABAS office for reference). c. To engage the same consultant to carry out design works and supervision of work. d. The developer must engage consultant supervisor to do supervision of works based on the following category :- i). Supervision for civil works on pipeline, reservoir and pump house shall be as follows:- For housing development in progress at any stage less than 100 units or equivalent to 33,000 gallon per day intermittent supervision by one full time technician. For housing development in progress at any stage between units or equivalent between 33, ,000 gallon per day full time supervision by one full time technician. For housing development in progress at any stage between 500 1,000 units or equivalent between 165, ,000 gallon per day supervision by one full time civil engineer and one technician. For housing development in progress at any stage more than 1,000 units or equivalent more than 330,000 gallon per day supervision by one full time civil engineer and two technicians.

Supervision for works involving mechanical & electrical and telemetry systems shall be by a qualified electrical or mechanical engineer and be engaged when works are being carried out at project site. e. Developer through its consultant must submit the curriculum vitae of consultant supervisor who should have more than 5 years experience related to water supply works and must be approved by SYABAS. Any works found at site without the consultant supervisor as required, can be rendered as not acceptable and lead to SYABAS not taking over the external water supply system. f. To appoint a contractor registered with CIDB or PKK with relevant sub head related to water supply works. g. To engage a registered plumber, with registration from Jabatan Kawalselia Air Selangor. h. Any water supply system completed without approved plan by SYABAS and works not supervised by consultant will not be taken over by SYABAS. i. Developer is responsible to repair and make good any defects during the defects liability period which in general is 36 months after the date of taking over ( but is subjected to details in SYABAS s letter to REDHA ref. No(6201) dlm.syabas 22/1/315 dated 8 November 2006 on the defect liability period. Developer is also responsible to repair and make good any latent defects which appear after defects liability period due to negligence, inferior quality of materials and shoddy workmanship. j. Developer is required to deposit a bank guarantee against defects as a condition to the taking over of water supply system by SYABAS. Bank guarantee value will be based on 5% of SYABAS estimated value of construction cost of the water supply system involved, including civil and M & E works. k. Developers are expected to complete the permanent water supply system on time for their own development. No temporary water supply will be considered. For big development projects, developer needs to plan and develop a complete water supply system for phased development to be handed over to SYABAS in stages.

5 Page 5 of 6 l. Developers are required to allow access at their respective project site and assist SYABAS staff to carry out site inspection on ongoing works as directed. m. The developer has to make sure that stealing of water does not take place at project site. vi) Role of Consultant a. To prepare a quality assurance plan b. To supervise all works through its site representative c. To ensure all works are built according to approved drawings and specifications d. To prepare bimonthly progress reports and works programmes. e. Consultant shall take full responsibility for all proper study, design, authority approval, specification, construction drawings, supervision, material inspection, testing and commissioning. f. Consultant will not be relieved of its design obligation and supervision even after the water supply system is taken over by SYABAS. 3.2 General Conditions a. The quantity of water for construction supply and testing purposes can be given in 2 stages:- Stage 1: For construction supply, the meter installed at site shall be small (generally not more than 25 mm diameter). Water for construction supply will be used for construction, leakage and pressure testing and general cleaning purposes Stage 2: For pump testing and flushing purposes, the meter can be increased to full bore diameter, for example 100 mm diameter (generally) depending on water requirement of the water supply system. Water for sterilization and flushing and pumping system test shall be obtained after connection to the existing mains has been carried out. b.
