F. Retention and Detention Pond<br />
The application of MASMA standards in SJER will result in a greater<br />
emphasis on providing retention and detention ponds or lakes to<br />
improve water quality, minimize flooding and improve the quality of the<br />
environment. The water in the ponds or lakes can be used to dilute rivers<br />
especially during dry season.<br />

KEY DIRECTION<br />
The need for sustainable sewerage system in SJER.<br />
All new housing development to be connected to the ecofriendly<br />
centralized sewerage system (CSS).<br />
All land made available for Sewerage Treatment Plants must<br />
be primarily reserved and designated for public purposes.<br />
Silt traps should also be constructed in many tributaries especially at the<br />
new development areas.<br />
H. Guidelines for Sustainable Storm Water Drainage & Flood Mitigation<br />
• Install trash racks or screens to trap debris/litter;<br />
• Allow for buffer strips and grass swales to protect water source<br />
from contamination by nearby development precinct.;<br />
A. Existing Sewerage System<br />
Sewerage waste in the District of Johor Bahru comes from both public<br />
and private sewerage plants, individual septic tanks (IST), primitive<br />
systems (villages and illegal squatters) and untreated discharge<br />
from households. As Indah Water Konsortium is only responsible for<br />
maintaining public treatment plants, many other forms of treatment<br />
plants are currently not properly maintained.<br />
• Install GPT and oil/grease traps in major drains at strategic<br />
locations;<br />
• Install series of bio-retention /infiltration porous systems for storm<br />
water to get back into the ground;<br />
• Install buried drainage pipes to cater for major storm; and<br />
• Install water collection equipment, storage and pump for recycle<br />
storm water as non-potable water.<br />
Sewerage Treatment Plant at Taman Suria Johor Bahru<br />
For land under development which has a gradient of less than 30º<br />
but greater than 25º, geo-technical analysis, analysis on contour and<br />
drainage pattern and an EIA study should be included. All hill slopes<br />
have to be closely turfed after cutting.<br />
<strong>14</strong>.9 Sewerage<br />
The Department of Sewerage Southern Region (JPP) is the government<br />
agency responsible for the management of sewerage in the District<br />
of Johor Bahru. Meanwhile operation and maintenance services is<br />
carried out by a concession company, Indah Water Konsortium (IWK).<br />
The process of taking over maintenance work has been carried out<br />
progressively by JPP since 1995. Untill now only the areas under the City<br />
Council of Johor Bahru and areas outside of Municipality Councils have<br />
not been taken over.<br />
