D. Current Development
•
Systematic planning and development of
Sewerage Infrastructures in Sarawak commenced
under Ninth Malaysia Plan(from 2006)
•
Main Emphases are on :
(a) Provision of a Centralized Sewerage System
for Kuching City
(b) Provision of a Centralized Sewerage System
for Miri City
(c) Provision of Septic Sludge Treatment Plants
for major towns
(d) Formulation of Centralized Sewerage System
Master Plans for major towns
11
Kuching City Centralised Sewerage System
Masterplan (2003)
Centralized Sewerage System in Kuching City (Package 1)
-Proposed 67,000 PE with Trunk Sewer for 270,000 PE
13
Key Features of Kuching Centralised Sewerage
System Package 1 Which Will Set the Direction
for Future Centralised Sewerage Infrastructure
Development In Sarawak
•
True gravity flow – one pump station
•
Micro-Tunneling extensively used
•
Modular Construction of Treatment Plant
•
Inclusion of Property Connections in the Contract
14
Shaft Construction in Progress
15
Tunneling with 1.5 m diameter Tunnel Boring Machine (TBM)
in progress at Manhole T12 (Trunk Sewer)
16
1.5 m diameter Connecting MH-T6 to MH-T7A Under Sarawak River
17
Miri Centralised Wastewater Management System Phase 1
 Main Components:
a) Centralised Sewage
Treatment Plant
(100,000PE module)
b) Sewer Network
 Trunk Sewer (0.6m to
1.8m dia.)–15km
 Local Sewer (0.225m
to 0.45m dia.)–51km
c) Property Connection 3,000 properties
 Status :

Survey and Design Stage
(target to call tender by
February 2016)
Septic Sludge Treatment Plants
 To enable Scheduled Desludging of septic tanks
and package plants to improve their treatment
efficiency.
 Existing three plant : Matang, Sibu and Miri.
 Priority Towns: Sarikei/Bintangor, Sri
Aman/Betong, Kapit and Limbang.
 Mechanism: SSD builds and operates the plant.
Local councils desludge and send sludge to the
plant for treatment. Local councils collect through
council rates and pay for the operation of the
plant.

Master Plan Studies
Cities and municipalities currently with Central
Sewerage Master Plans are :
Kuching (2003), Sibu (2009) and Miri (2009). Bintulu
Sewerage Master Plan is completed by Bintulu
Development Authority (1980’s).
Priority towns for Master Plan Studies are:
Samarahan, Mukah and Sarikei/Bintangor.

E. Future Direction
Project Financing
 Capital Expenditure by Government
 Operating Expenditure by Users
21
Institutional Arrangement
 Department
shall plan, implement and
operate new public centralised sewerage
systems.
 Local authorities will still operate existing
treatment
systems
rationalised.
until
these
are
22
Public Acceptance/Rejection
 Individual Septic Tanks are generally acceptable
to the public and it costs them nothing.
 We need awareness programs and public relation
exercise to change this mindset.
 We have to move the mindset of the general
public from “sanitation and public health” to
“water resource and environmental protection”.
23
Our Success will depend on:
 Efficient Management and Public Relation:
 Construction Stage (traffic management and
property damages)
 Connection Stage (enter private properties)
 Operation and Maintenance Stage (billing)
