Bintulu and Kuching Sewerage System

Bintulu Sewerage System

Bintulu Sewerage System is a Centralized Sewerage System, and it is the only town in Sarawak that uses this system. Now Kuching City is also constructing the same centralize system. However, Bintulu is facing problems in managing the system. As reported in the Borneo Post, March 26, 2010, Kidurang assemblyman has called on the authority to set up a "special task force" to manage the system. This is due to the overflowing manholes at many places. The overflowing sewerage is actually raw sewage coming straight from the toilets and bath rooms of the houses and shops. Many estates do not have septic tank anymore and the waste water are directly connect into the pipe system that carry the discharge into the oxidation pond.

Kuching City Sewerage System

Kuching city had been declared as "Bandaraya" since 1988, and furthermore to improve the environmental quality and the image of the city as a "Healthy City", and "Bandaraya Lestari" , a centralized sewerage system is now underconstruction see Figure below:

This system collects wastewater from kitchens, bathrooms, wash areas (greywater) and toilets (Blackwater) to be channelled through an underground pipes system into a sewerage treatment plant. The plant treats the wastewater before discharging back into the environment with an acceptable quality.

You said, "This is due to the overflowing manholes at many places. The overflowing sewerage is actually raw sewage coming straight from the toilets and bath rooms of the houses and shops."

The question to ask is: Why does the manhole overflow? The most probable reason is that pipes have collapsed because of bad construction. I recently completed works for a CCTV company which does CCTV work on underground sewerage pipes. The number of subsidence which should have been re-excavated and re-laid is unbelievable.
Many repair works that should have been done were not done. the problem you are complaining of is imminent in Kota Kinabalu.
I had tried getting the contractor and JKR Sabah to get it repaired before the defect liability period is over but nothing has been done to date.

4. Logical Framework for Integrated River Basin Management

4.1 Introduction The logical framework approach (LFA) was first adopted by U.S. AID in the early 1970s. The framework provides a set of designing tools that, when used creatively, can be used for planning, designing, implementing and evaluating projects (the entire project cycle). The purpose of LFA is to undertake participatory, objectives-oriented planning that spans the life of project or policy work to build stakeholder's team commitment and capacity, through a series of workshops. The technique requires stakeholders to come together in a series of workshops to set priorities and plan for implementation and monitoring. This achieved by structuring the main elements of project in a matrix (the logical framework) which summarizes the project, highlighting logical linkages between intended inputs, planned activities and expected results and records the underlying assumption. See Figure 4.1, for the content of framework matrix and how to read the LFA. 4.2 Steps in Logic

River Basins in Sabah

Figure 1 Rivers and Points Annual Rainfall at Sabah (After Sabah Water Resources Master Plan, 1995) The best source of information about river basins in Sabah is from the "Sabah Water Resources Master Plan", which can be seen at http://www.did.sabah.gov.my/ . The river basins are can be grouped as those that discharging the flow to the west coast, north coast, and to the east coast. Some rivers that go to west coast are: Sg. Mayog/Babogon Sg. Papar Sg. Padas Some rivers that go to the north coast are: Sg. Bandau Sg. Bangan/Kinorom Sg. Bengkoko/Pitas Some rivers that go to the east coast are: Sg. Liwagu Sg. Kinabatangan Sg. Tawau Sg. Merotai Besar The Figure 1 shows the points annual rainfalls and rivers in Sabah.
