What is the Mamallan reservoir and why does it matter?

It is a 170 MLD storage project with an outlay of Rs 342.6 crore. It adds buffer capacity to smooth seasonal demand and improves network stability when paired with ring-main and SCADA. For Chennai water supply, this supports steady pressure, better quality, and fewer outages across zones.

How will 24/7 piped water Chennai be delivered?

The plan couples storage with a ring-main, district metered areas, and SCADA for pressure control. Smart meters enable fair, volumetric billing. Together, these pieces reduce leaks, maintain steady flows, and improve response times, allowing the utility to move from intermittent supply to reliable round-the-clock service.

Where are the investment opportunities in this buildout?

Expect tenders for EPC works, pipelines, pumps, valves, and control systems. Smart-metering and IoT vendors may see pilots scale into citywide deployments. PPP models could bundle operate-maintain obligations with performance-linked pay, while AMRUT 2.0 and JICA support can improve bankability and lower funding costs.

What is AMRUT 2.0’s role in urban water projects?

AMRUT 2.0 backs universal coverage, metering, and loss reduction with reform-linked funding. It encourages 24/7 service goals, better billing, and transparent reporting. By aligning tenders and outcomes with program rules, cities can secure grants or concessional finance that accelerate upgrades and support sustainable operations.

January 19: Chennai Rs 342.6-crore reservoir, 24/7 water push lift infra bets

ByHuzaifa Zahoor January 19, 2026

Chennai water supply is set for a step-up with the Rs 342.6-crore Mamallan reservoir of 170 MLD and a 24/7 metered-supply pilot backed by ring-main and SCADA upgrades. The foundation stone is laid, signalling execution-ready works and a clear tender runway for EPC, desalination, and smart-metering vendors. Policy anchors include AMRUT 2.0 and JICA support for integrated projects. This mix points to multi-year orders and new municipal-finance needs as the city targets reliable, round-the-clock service source.
