PROFILE COMPANY
1.1 Background of Indah Water Konsortium(IWK) Sdn Bhd
Indah Water Konsortium, a wholly-owned company of the Minister of Finance
Incorporated, is Malaysia's national sewerage company which has been entrusted with the
task of developing and maintaining a modern and efficient sewerage system for all
Malaysians.
In 1994, the Federal Government awarded the company the concession for nationwidesewerage services which prior to that, was under the responsibility of local authorities.
Since then, Indah Water has taken over the sewerage services from local authorities in all
areas except the States of Kelantan, Sabah, Sarawak and the Majlis Perbandaran Johor Bahru.
A modern and efficient sewerage system is vital for the country so as to ensure that
wastewater is treated before being discharged into our rivers. This will help preserve the
country's waste resources, protect public health and provide a cleaner and safer environment.
In June 2000, as testimony of the Government's seriousness in ensuring that a proper and
efficient sewerage system will be successfully put in place and maintained, the Government,
through the Minister of Finance Incorporated, took over the entire equity in Indah Water from
its previous private owners.
Indah Water is now well-positioned to undertake the vital task of ensuring that Malaysians
today and in the future will be able to enjoy a clean and healthy environment through a
proper and well-maintained sewerage system.

2.0 Main Text
2.1 Indah Water Services
There are mainly two types of sewerage systems/services in Malaysia. The
premises' sewerage systems are either connected to a public sewage treatment plant or
have an individual septic tank.
IWK is mainly responsible for operating and maintaining the public sewage
treatment plants and network of underground sewerage pipelines.
The services are rendered through the company's 18 Unit Offices/Customer
Service Centres located throughout the country, except Johor Bahru, Kelantan, Sabah
and Sarawak. Customers can also pay their Sewerage Services Bills at these centres.

2.2 Connected Service
Connected sewerage service customers have sewage outlets that are directly linked to
a sewage treatment plant via an underground network of sewer pipes. IWK is responsible for
the operations and maintenance of all public sewage treatment plants. Public sewage
treatment plants are plants which have been handed over to the Government (National Water
Services Commission, Ministry of Energy, Green Technology & Water) by the Developer.

Premise with connected sewerage service/system has one rectangular metal cover,
which is called an inspection chamber and usually located outside the premises compound
either at the side, rear or front. In the inspection chamber are sewage outlets from the
premises' toilets, bathrooms and kitchen that are connected to the public sewerage pipelines
to the public sewage treatment plant. If there is any blockage, the checking and clearing of
the blockage will be done via the inspection chamber.
However, in the case of bungalow houses, there are usually more than one inspection
chambers depending on the number of toilets and kitchen in the house. If the house has 5
toilets and one kitchen, there will be 6 inspection chambers located outside the premises
compound instead of just one inspection chamber. More often than not, owners of bungalow
houses tend to think that the inspection chambers are septic tanks. (Septic tanks are usually
arranged in series and not located in various places outside the premises' compound)
Another frequent confusion with this type of system is the differentiation between
internal or private and public sewerage pipes. Many users are unaware of their ownership and
responsibility to repair or replace broken pipes and remove clogged pipes between the
inspection chamber and the public sewerage pipes or manhole at their own expense. IWK is
mainly responsible for the maintenance of the public sewerage pipes.
2.3 Individual Septic Tank
Malaysia's most common form of sewerage system is the individual septic tank (IST).
There are an estimated 1.2 million premises with individual septic tanks in the country.

Premises with a proper individual septic tank (Malaysian Standards - MS 1228) has 3 to 4
rectangular metal covers and is usually located outside the premises compound either at the
side, rear or front. The septic tank only provides partial treatment of the sewage that flows
into it and needs to be desludged on a regular basis, approximately once in two years, to
ensure that it functions efficiently. IWK provides this important and mandatory scheduled
desludging service to government premises.

2.4 Refurbishment
One of Indah Water's vital services is refurbishment. The rehabilitation work on
existing plants with same capacity and or treatment processes will enhance the effectiveness
and efficiency of such plants in addition to improving the aesthetics. The process entails
fairly-complex works ranging from civil engineering aspects of safety, security, cleanliness
and aesthetics, to the highly-complex skilled mechanical and electrical serviceability of the
plants. Currently, over 5,408 public sewage treatment plants and pump stations are
undergoing total refurbishment.
Refurbishment work involves the tidying up of treatment plants and pump stations
with improved aesthetics and security; the repairing, replacing and testing of pumps, float
switches and associated valves and pipeworks; the repairing, replacing and testing of
treatment process equipment; the desludging of plants including holding tanks; the repairing,
replacing and testing of High Voltage and Low Voltage electrical services including electrical
wiring, control panels, lightning protection, etc; the sampling of effluents to ensure applicable
environmental standards are met; and the inspection, repairing and/or replacement of critical
sewer pipework.

It takes anywhere between three to 24 months to refurbish a plant.
Assuming one plant is fully refurbished in a day, it would take over 14 years to refurbish all
of Malaysia's public sewage treatment plants. However, Indah Water aims to complete all
refurbishment on a priority basis within six years.

3.1 Introduction to green technology
Global environmental issues, such as climate change and deforestation, have emerged
as new challenges to people throughtout the world. Many countries with aims to become a
low-carbon society through green growth achieved via green technologies and green
industries which enhance eco-efficiency while minimizing adverse environmental impacts.
Green Technology is the development and application of products, equipment and
systems used to conserve the natural environment and resources, which minimize and reduces
the negative impact of human activities.
Criteria of Green Tech products, equipments or systems:
It minimizes the degradation of the environment;
It has zero or low green house gas (GHG) emission;
It is safe for use and promotes healthy and improved environment for all forms of life;
It conserves the use of energy and natural resources; and
It promotes the use of renewable resources.
3.2 National Energy Balance
National Energy Balance (NEB) is design to illustrate the energy supply and demand
balance reflecting the Reference Energy System of the country. The energy balance is a
presentation of the basic supply and demand data for all fuels in a manner, which shows the
main fuels being separately distinguished and expressed in a common energy unit. Both of
these characteristics will allow the comparison of contribution each fuel makes to theeconomy and their interrelationships through the conversion from one fuel to another. NEB
was carried out to cover a broad area in energy disciplines such as supply and demand sector
in this country based on the standard format recommended by the United Nations. NEB will
present time series statistical data on the supply, transformation and demand of commercial
energy sources as well as providing a comprehensive support for integrated energy planning.
Data providers for the compilation of NEB consists of relevant government agencies, power
utilities, independent power producers (IPPs), private oil companies, as well as the cement
and iron and steel manufacturers.

3.3 Waste Water Treatment
Industrial wastewater treatment covers the mechanisms and processes used to treat
waters that have been contaminated in some way by anthropogenic industrial or commercial
activities prior to its release into the environment or its re-use. Most industries produce some
wet waste although recent trends in the developed world have been to minimize such
production or recycle such waste within the production process. However, many industries
remain dependent on processes that produce wastewaters.
