D. Existing Requirements<br />
SJER lacks a modern sewerage system and most households rely on<br />
individual septic tanks in the city of Johor Bahru. This is main source of<br />
pollution for many of the rivers in SJER and measures need to be taken<br />
to resolve this issue.<br />

E. Projection of Land Required for Sewerage Treatment Plan<br />
The future sewerage treatment system shall be mechanical and a total<br />
land area of 195 acres will be required by the year 2025.<br />

F. Proposal For Eco-Friendly Sewerage Treatment<br />
The proposed sewerage treatment system for SJER combines both<br />
primary and biological treatment in order to ensure effluent complies<br />
with Standard A of the Environmental Quality Regulations (Sewage<br />
and Industrial Effluent), 1979 and Class 1 of the National Water Quality<br />
Standard before being discharged into any rivers or water bodies.<br />
The Up Flow Anaerobic Sludge Blanket/Continuous Sequencing Batch<br />
Reaction (UASB/CSBR) treatment system shall be adopted for primary<br />
treatment.<br />
The UASB reactor is an anaerobic biological treatment system requiring<br />
no energy to operate. The sewage is anaerobically digested with<br />
potential Biological Oxygen Demand (BOD) reductions of 50% to 70%.<br />
Methane gas generated from the process shall be stored to be used to<br />
generate power for the plant.<br />
