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.

9/18

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.

10/18

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.

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.
