Kerala Water Authority Plans Rs 45 Crore Tertiary Sewage Recycling Scheme
Kerala's water authority is planning a Rs 45 crore tertiary sewage recycling project in Thiruvananthapuram, the Times of India reported on 19 October 2026. The project falls under the water and sewerage pipeline and distribution sub-sector and marks a further step in the authority's infrastructure activity in the state capital.

Authority's Broader Project Footprint in Kerala
Projects India tracks several other schemes associated with Kerala-linked promoters in Thiruvananthapuram and the wider state. These include a sewage treatment plant project at Alathur, Palakkad valued at Rs 1 crore, and a bio-medical waste treatment facility expansion at Kunnathunad, Ernakulam valued at Rs 5.8 crore, the latter of which has reached the construction-started stage. The new tertiary recycling scheme in Thiruvananthapuram represents a notably larger capital commitment than either of those tracked projects in the state.
Comparable water and sewage treatment activity is also visible elsewhere in southern India. The Bangalore Water Supply and Sewerage Board has two projects under approvals in Karnataka — a water, sewage treatment and tertiary treatment project at Byramangala valued at Rs 303.26 crore, and a water, sewage and effluent treatment project at Bellandur valued at Rs 200 crore — indicating that tertiary treatment and recycling is a recurring theme in urban water investment across the region.
National Pipeline: Scale and Distribution of Tracked Projects
Projects India tracks 7,653 live projects in the water and sewerage pipeline and distribution sub-sector, with 11 added in the last 90 days. The concentration of activity is heaviest in Uttar Pradesh (779 projects), Gujarat (735), Bihar (725), Maharashtra (720), Karnataka (647) and Jharkhand (502). Kerala does not appear among the top six states by volume, but the Thiruvananthapuram scheme illustrates that investment is continuing in southern coastal states as well.
The stage breakdown of tracked projects in this sub-sector points to a substantial forward pipeline. Of 7,653 projects, 5,364 are under approvals — representing the largest pool of early-stage opportunity for suppliers and contractors. A further 1,448 have reached the construction-started stage, 379 are in planning, 107 have approvals received, and 119 are at the early or announced stage. Only 129 are recorded as completed.
Context: Recent Sewage and Water Investment Nationally
The Kerala announcement follows a pattern of large-scale sewage investment at the national level. The Delhi Jal Board has approved a Rs 17,969 crore sewer overhaul plan, while water supply constraints have also affected project timelines in Kerala itself — a Rs 200 crore plan for the Aruvikkara water plant was reported as stalled by a funds crunch. The Rs 45 crore tertiary recycling project in Thiruvananthapuram is a smaller but distinct addition to that landscape.
Uttar Pradesh Jal Nigam has also commenced construction on a water, sewage and effluent treatment plant at Malihabad, Lucknow, valued at Rs 135.6 crore, further reflecting broad-based national momentum in sewage treatment infrastructure.
What this means for suppliers and contractors
The Thiruvananthapuram tertiary sewage recycling project, at Rs 45 crore, is at the announced stage and no tender information has been published as yet. Projects India currently records zero open India tenders in the infrastructure projects sector, meaning suppliers tracking this opportunity should monitor for procurement activity as the project advances through approvals.
For equipment makers and civil contractors specialising in tertiary treatment technologies — including filtration, membrane systems and recycled-water distribution — the project joins a pipeline where 5,364 of 7,653 nationally tracked water and sewerage projects remain under approvals, representing a substantial volume of work not yet awarded. The highest-density states for this pipeline are Uttar Pradesh, Gujarat, Bihar and Maharashtra, though schemes in Karnataka and Kerala demonstrate that southern India continues to generate significant investment. Suppliers capable of working across geographies have a wide range of opportunities to pursue as approvals convert to tenders.
