ISSUE :
Melaka drought at the end of January 2014,
when the level of Sg Melaka found to decrease
from the normal level (2.5m).
IMPACT :
 This causes the supply of 48 MLD raw water
to the Bertam WTP affected.
 12 Feb 2014, Bunded Storage dried &
affected the operational of Sebukor WTP (77
MLD) need to be stopped. The plant ceased
operations for 11 hours.
 Durian Tunggal Dam & Jus Dam level that
continued decreased.

CASE STUDY II
RAW WATER QUALITY DETERIORATION IN MERLIMAU
Unstable Water Resources Quality
ISSUE :
21 June 2014, the Merlimau WTP has been closed due to raw water
pH is too low. This WTP closure has caused some areas in Jasin
District disrupted water supplies, including the north, Jasin, whole
Merlimau including Sungai Rambai and Serkam.
COMPREHENSIVE ACTION

Water supply has been extended from the district of the Kolam
Bemban & Umbai.

Water Supply is also taken from Syarikat Air Johor (SAJ) at
Sungai Rambai (Ledang) and Chohong(Tangkak).

Some work system changes made ​with pipe connection to the
existing pipe to the affected areas.
Setting Up A Task Force
KEYS INITIATIVES
 Raw Water Piping From Outfall Sg Kesang To Lanchang Intake
 Proposal System Improvement Of Chin Chin WTP

CASE STUDY III:
EMPOWERING OPERATING
SYSTEM WATER SUPPLY OF MELAKA
18 July 2014: Start of operations DAF II WTP has been
strengthening and empowering operational water
distribution system in Melaka.
EVIDENCE OF IMPLEMENTATION:
 By operating the DAF II WTP, the water supply can be
extended to Sg. Udang. Therefore, this can reduce the
dependency on Bertam WTP.
 The flexibility of this interconnectivity, can take advantage
of to supply water to the area Merlimau.
RESULTS:
Overall, the available performance interconnectivity Melaka
was 100%
