<strong>14</strong>.6 Water Supply<br />
Table <strong>14</strong>.7: Existing SJER Water Supply<br />
A. Introduction<br />
Treatment Plant<br />
Water Supply (mld)<br />
The current supply of water is adequate in meeting the needs of SJER,<br />
with a reserve of about 100%.<br />
Heavy industries in Pasir Gudang, new industries in Nusajaya and other<br />
industrial areas, as well as the associated population increase will<br />
require that the water supply system (comprising the source, headworks,<br />
transmission, and storage and distribution network) be augmented<br />
significantly.<br />

KEY DIRECTION<br />
UI 4 : Ensure a reliable source of high quality water and preserve<br />
existing water catchments areas that serve SJER.<br />
B. Water Demand<br />
Demand for water within the SJER in the year 2005 was in the region of<br />
537 million litres per day, as illustrated below.<br />

D. Non-Revenue Water (NRW)<br />
Within SJER, Non Revenue Water (NRW) is very significant. NRW is the<br />
difference between the total volume produced by water treatment<br />
plants and total volume of water legally used. This difference in volume<br />
is generally due to the following:<br />
■ Leakage in distribution pipes, faulty valves and water wastage<br />
due to improper pipe fittings, as well as burst pipes;<br />
■ Operation of fire hydrants and flushing of main pipes;<br />
■ Illegal pipe connection, for instance, tapping illegally from fire<br />
hydrant; and<br />
■ Meter vandalism.<br />
In relation to the above, SAJH has taken various steps to improve<br />
security by putting up fences. SAJH has implemented various programs<br />
to upgrade the old pipes since 1995 and reduced NRW from 47% in<br />
1992 to 27% in year 2000. SAJH has forecast that NRW in the region will<br />
reduce to between 25%-20% in 2010.<br />
C. Water Resources<br />
Syarikat Air Johor Holdings Berhad (SAJH) is the body responsible for the<br />
supply of treated water in SJER. There are six treatment plants, which<br />
supply 858 million litres of treated water per day to consumers in SJER.<br />
Raw water is sourced from three rivers namely Sungai Layang, Sungai<br />
Johor and Sungai Pulai.<br />
E. Existing Water Requirements<br />
From the analysis shown, there is a surplus of water of <strong>14</strong>9.9 million litre<br />
per day. to cater for immediate needs and development pressure.<br />
