I am pleased to present Pengurusan Air Selangor Sdn Bhd’s (Air Selangor) first Performance Report for the activities from 2011 to 2015. The report sets out the services provided by our subsidiary companies, namely Syarikat Bekalan Air Selangor Sdn Bhd (SYABAS), PNSB Water Sdn Bhd (previously Puncak Niaga Sdn Bhd), Konsortium ABASS Sdn Bhd (ABASS) and Konsortium Air Selangor Sdn Bhd (KASB); to our customers over the past five years.

Our activities are driven by our ongoing commitment to provide value for money water services to customers. We recognise that we need to continuously improve to ensure that our customers receive excellent services. However, we know there is more we can do and everyone in Air Selangor is committed to maintaining our recent improvements.

There have been a number of key initiatives in the year to improve communication with our customers. Information on water conservation, services and billings are printed at the back of the water bill in the form of an illustration. In addition, alert messages are disseminated electronically through Facebook, Twitter and smart

phone application “MySYABAS” as well as “WhatsApp” Messenger Service groups. These social media platforms have been particularly useful in keeping customers up-to-date whenever there are unplanned water supply interruptions.

Our on-going investment in water pipe leak detection and repair has enabled us to manage the leakages through District Metering Zones (DMZ) and Pressure Management Zones (PMZ) to gradually reduce the Non- Revenue Water (NRW) from 34% to 25% by 2025. As at December 2015, the NRW had been reduced to 32%.

We have a planned capital investment programme to deliver the investment required to provide our customers with improved services, particularly in minimising water interruptions and providing adequate water supply. However, these plans will only be implemented upon obtaining approval from the National Water Services Commission (SPAN).

I hope that you will find the report both interesting and informative. Next year, we’ll report on the progress of the planned capital investments.

OVERVIEW OF WATER SERVICES INDUSTRY

The water services industry in Selangor, Kuala Lumpur and Putrajaya underwent a restructuring exercise in 2015. The acquisition and consolidation of the water concession companies were undertaken by Pengurusan Air Selangor Sdn Bhd (Air Selangor), a wholly owned company of the Selangor State Government.

Air Selangor acquired four concession companies, namely Syarikat Bekalan Air Selangor Sdn Bhd (SYABAS), Puncak Niaga (M) Sdn Bhd (PNSB), Konsortium ABASS Sdn Bhd (ABASS) and Konsortium Air Sealngor Berhad (KASB). The acquisition of Syarikat Pengeluar Air Sg Selangor Sdn Bhd (SPLASH) is targeted to be completed towards the end of 2016.

After successful consolidation of all the water concession companies, Air Selangor will be the sole water supply service operator providing holistic water services from raw water abstraction and treatment to the distribution of treated water to consumers, including customer services and billings in Selangor, Kuala Lumpur and Putrajaya.

Air Selangor will be operating under the regulatory framework of the Water Services Industry Act, 2006 (WSIA) and Lembaga Urus Air Selangor (LUAS) Enactment, 1999 respectively under the regulation of the National Water Services Commission (SPAN) and Selangor Water Management Authority (LUAS).

Air Selangor operates & maintains 27,800 kilometres of water pipes, which is equivalent to the flight distance for two return trips from Kuala Lumpur to Mecca (6,977 km one way)

* Total No. of Employees: 4,198

WATER TREATMENT PROCESSES

The fully conventional water treatment system comprises vital processes, such as aeration, coagulation and flocculation, sedimentation/clarification, filtration, disinfection and pH adjustment.

Sg. Rumput and Kepong WTP were upgraded in 2007 to advanced ultrafiltration membrane system. Raw water is filtered through the ultra-membrane filtration system to remove suspended particle, colloids and bacteria without the addition of any coagulants.

The water clarification process is by Actiflo-Settler, a compact unit with a high degree of operating flexibility. It uses micro sand as the catalyst to expedite the clarification process with facilities to recover the sand used. This system enables the clarification process time to be reduced from point of coagulation to outlet of the settling tank.

The principle of floatation is based on the transfer of particles to the surface of a liquid through attachment of micro-bubbles to the particle surfaces.

HOW DO WATER METERS WORK?

A water meter is a mechanical device with a series of internal gears. These gears move as water flows through the meter, recording your usage. This process is similar to how an automobile odometer records the mileage as the tyres rotate.  All meters are factory calibrated to industry standards prior to being shipped, and last 10 to 15 years. After that time, they can begin to wear, allowing more water to flow through the period than is actually recorded with the result being an underbilled customer.

Lift the meter counter cover.

The meter counter displays 8 digits, 4 digits in white and 4 digits in red.

The reading on the meter counter shows the consumer’s total water consumption is 748.1910m3 and therefore the bill is issued as 748m3.

Consumer Account Number consists of 13 digitsFirst 2 digits indicate the “District Code”Subsequent 10 digits denote the “Consumer Account Number”The 13th. digit is the “Check Digit”

HOW TO READ WATER METER?

WATER ACCOUNT NUMBER?

Malaysia’s water consumption is typically 230 litres per day per person as compared to Europe’s 160 litres per day, Singapore’s 150 litres per day and Thailand’s 180 litres per day

On average, most water pipes in Selangor and Kuala Lumpur are more than 30 years old.

About 49% of pipes are mild steel, 23% asbestos cement, 13% Unplasticised Polyvinyl Chloride (uPVC) and 15% a mixture of various type of pipes. The frequent leaks and burst pipes problems are from the old asbestos pipes.

Another initiative to reduce NRW has been to identify illegal connection of water supply, namely at construction sites, abattoirs, high-rise properties etc.

As at December 2015, 682 illegal connection cases were resolved through legal actions amounting RM2.2 million. There are 1,295 cases amounting to RM9.2 million still being pursued by Legal Department.

On average, the NRW had gradually reduced to 32% or 1.5 million m3 per day as at December 2015.

For the past five years, NRW losses due to water theft registered over 12,000 m3 worth RM 32 million from more than 3,000 cases.

WATER LOSSES? WE LOSE WATER IN A NUMBER OF WAYS

WATER THEFT

Did you know?One can be infected by water borne diseases due to improper or illegal connection of pipes

Water Pipe Leakages

Water Meter

Illegal Connection / Water Theft

On average, there are 211 leaked pipes a day. The pipes are repaired immediately upon receiving feedback from the public at large or identified through internal monitoring systems.

In cases of frequent burst pipes, a replacement programme is put in place to replace the pipes which are old and economically not worth repairing. The cost for replacing 1 kilometre of damaged or old pipe is close to RM1 million.

Old water meters, which are more than 10 years old, is one of the causes of inaccurate water usage readings.

Occasionally, water meter not installed based on specifications could also cause inaccurate water usage readings.

In 2015, 997 cases of water theft were detected with losses worth RM2.1 million for 6.4 million m³ of water.

A dedicated team has been formed to detect illegal connections on a full time basis.

WATER METER REPLACEMENT

From 2011 to 2015, 1,159,894 water meters were replaced, comprising 44% (511,798) 10 years old water meters and 56% (648,096) faulty water meters.

Life span of water meter is typically 10 years old, which needs replacement

OUR CUSTOMER RELATIONSHIP SERVICES

The Call Centre operates 24 hours a day and 7 days a week on 3-work shifts with a pool of 60 agents supported by Call Logging and Telephony System.

In March and April 2014, a long dry spell resulted in water rationing that affected many consumers. Hence, there were numerous calls received enquiring and requesting for water supply. The highest number of calls received was on 6 April 2014 with 14,688 calls.

In 2015, the incoming calls were reduced to 1.2 million or an average of 3,379 calls per day mainly on water interruptions due to pipe bursts and leaks.

As part of the initiative to provide early warning to affected consumers during temporary water interruptions and prevent congestion of the telephony system, the Customer Service Department embraced social media, namely ‘Facebook’ and ‘Twitter’ in 2009, created ‘Whatsapp’ messenger group as well as ‘MySyabas’ smart phone application in 2014 to provide status update to residents associations, opinion leaders and community leaders.

To date, 32,332 consumers had downloaded the ‘MySyabas’ application to view scheduled and unscheduled water interruptions, check billing information, media releases and submit enquiries/complaints.

MIGRATION

From 2011, over 400,000 domestic premises have been successfully migrated to individual meters.

As of todate, there are 1,232 bulk meters in condominiums and 18 bulk meters in low-cost flats which have not been migrated.

For 2016, it is targeted that 90 bulk meters with 25,000 units of domestic premises will be migrated to individual meters.

Migration Programme was initiated in 2007 to assist residential buildings and gated communities’ Joint Management Bodies (JMB) or Management Corporations (MCs) in the collection of Water Bill payments from individual unit owners or occupants and alleviate the problem of bulk meter water supply disconnections due to mounting water bill arrears.
