Syarikat Bekalan Air Selangor Sdn Bhd (SYABAS) in Malaysia is the sole water distribution company supplying water to industrial and domestic users in the state of Selangor and the federal territories of Kuala Lumpur and Putrajaya. SYABAS relies heavily on a network of TBox remote telemetry units (RTU) relaying information to their SCADA system to provide real-time monitoring and control of their water distribution network that delivers water to

their 2million customers.

Controlling and monitoring Malaysia’s largest water distribution network

CASE STUDY

About water services in MalaysiaThe Malaysian government aims to have 99% of

its population served by clean and treated water

by 2020. In achieving this vision, the Malaysian

government set the following objectives:

• Everyone will have access to safe, adequate

and affordable water supply, hygiene and

sanitation.

• The provision of sufficient water will ensure

national food security and promote rural

development.

• There will be provision of sufficient water to

spur and sustain economic growth within the

context of a knowledge-based economy and

e-commerce.

• The water environment will be protected

to preserve water resources (both surface

water and groundwater) and natural flow

regimes, bio-diversity and the cultural

heritage, along with mitigation of water-

related hazards.

Due to the vast area it covers across ten districts

and its network of thousands of pump houses

and reservoirs, SYABAS, assisted by Servelec

Technologies’ TBox devices, is at the forefront

of using remote telemetry technology to control

and monitor their distribution network.

The SCADA SystemSYABAS has a purpose built Operation Control Centre (OCC) based at its Kuala Lumpur headquarters, which is home to its central SCADA system. The operation of the system relies on a mixture of TBox remote telemetry units installed in over 200 pump houses and reservoirs, each connected to the OCC by 3G cellular communications and transferring data using the DNP3 protocol. The SCADA system and TBox devices support key features including:

• Independent automatic pumping control at pump houses.

• Manual control override from the SCADA master station.

• Communication between TBox RTUs and the OCC.

• SMS alarms to operations personnel directly from the TBox RTUs.

• Scheduled email reports to designated personnel directly from the TBox RTUs.

• Secondary web visualization in each TBox RTUs via a web browser.

• Secondary data historization using data logging in TBox RTUs.

The above features provide SYABAS with near real-time status of its water distribution networks enabling the provider to ensure an uninterrupted water supply to its consumers.

Industrial Internet of Things (IIoT)In its quest to continuously improve its water distribution services and become the industry leader in Malaysia, SYABAS is exploring Industrial Internet of Things (IIoT) technology, which Servelec Technologies is developing.

Servelec Technologies is building IIoT capabilities into its industry leading RTU products such as the TBox LT2. Traditionally RTUs have been ‘edge’ devices capable of monitoring, marshalling and transferring data from the operational technology (OT) environment. The TBox LT2 all-in-one Remote Telemetry Unit (RTU) is being developed as an MQTT-based edge/gateway device for marshalling and transferring data securely from remote OT devices to a company’s IT infrastructure. For remote networks with IIoT devices that are not easily accessible over traditional networks the TBox LT2’s M2M communication capabilities will be utilised.
