AVK Glenfield valve installed in the Kilpauk treatment plant in Chennai, India

Case

Century-old valve installation from Glenfield still operates flawlessly

A lot has happened in the world since 1914. But some things remain the same, which is also the case for a valve installation on a treatment plant in Chennai, India, still operating flawlessly.

The valve in question is a Glenfield 26” gate valve, and it is still working perfectly after more than a century of service. The valve is installed in the common header of the Kilpauk water treatment plant in Chennai and has been in continuous operation.

Introducing water treatment in the area

The Kilpauk water treatment plant, where Chennaites (people living in Chennai) first got the taste of treated water, is set to enter its 110th year of existence this year.

The 66 acres where the plant was built by engineer JW Madley, the man behind the project, has all the remnants of the British era and most of the machinery are considered an engineering marvel. The regulated water supply system to Chennai City was established in 1872 on commissioning of the scheme formulated by British engineer James Fraser.

To be able to tap the water from the Korataliar River, a six feet heigh dam was built across the river at Tamaraipakkam, about 27 km from the city. The surplus water flowing in the Korataliar got diverted into a nearby lake, the Cholavaram. From there, water was diverted to Red Hills Lake through a 4 km lower supply channel. The proposal of James Fraser confirmed that the Red Hills Lake would remain as the terminal storage point of water drawn from Korataliar River.

A safe solution was needed

The plant’s construction became a necessity after the open canal that was previously supplying water from Red Hills to Kilpauk shaft got polluted, which resulted in water-borne diseases.
JW Madley developed 14 slow sand filters which are still part of the plant today. This approach followed the principle that bacteria will eat bacteria, and it is said that water through this process has a 99.9% purity.

In 1927, Chennai got chlorinated water after JW Madley introduced it. In 1954, it was shifted to a rapid gravity filtration system. After 1954, several schemes for improvements and expansion of the system had been implemented and commissioned.

Despite the many improvements of the plant, the gate valve is still in place and working perfectly.
The plant currently provides 270 million litres each day to Chennai.
