Water stewardship
We design and implement industrial water reuse, sewage reclamation, WASH and watershed projects for businesses and communities.
WHAT WE DELIVER
A facility needs a reliable water supply. A school needs safe sanitation. A community needs healthier shared water resources. Each calls for a project designed around its own conditions, users and operating needs.
Assess and develop treatment and reuse systems that match available wastewater with appropriate industrial demand. In India, we work with our technical partner CEMCOT on water reuse and zero liquid discharge (ZLD), selecting the approach around site conditions, water quality and operating needs.
Develop projects that treat sewage for suitable non-drinking uses, including landscape irrigation and other applications defined by water quality and local requirements. Engineering and nature-based treatment can work together where the site allows.
Plan and implement WASH projects around the needs of schools, workplaces and communities. Water access, sanitation infrastructure and hygiene needs are addressed with the people who will use and maintain them.
Design and deliver rainwater harvesting, pond and catchment restoration, and groundwater recharge projects. Local water conditions and community stewardship guide the choice of intervention.
OUR TECHNICAL PARTNER IN INDIA
Our technical partner in India for water reuse and zero liquid discharge (ZLD). CEMCOT brings experience in shared effluent treatment, water recovery and ZLD systems serving Tamil Nadu’s tannery clusters.
Chennai Environmental Management Company of Tanners (CEMCOT) works with common effluent treatment plants in Tamil Nadu.
Our collaboration connects SIV’s project development and delivery coordination with CEMCOT’s technical experience in wastewater treatment, water recovery and ZLD systems.
Visit CEMCOTZero liquid discharge systems recover water for reuse and manage the remaining concentrated waste, with the aim of eliminating liquid effluent discharge. CEMCOT’s published portfolio includes these four projects.
Ranipet, Tamil Nadu
CEMCOT describes a common effluent treatment plant serving 77 tanneries, with treatment capacity of 4,000 m³/day. Its ZLD work combines reverse osmosis, evaporation, salt handling and the return of recovered water to tanneries.
Read CEMCOT’s RANITEC projectRanipet, Tamil Nadu
CEMCOT reports a 2,500 m³/day treatment plant serving 86 member tanneries. The ZLD project combines upgraded treatment, reverse osmosis and evaporation, with metered pipelines returning recovered water to the tanneries.
Read CEMCOT’s SIDCO Phase I projectRanipet, Tamil Nadu
A shared treatment system for a cluster of 40 member tanners. The ZLD project includes membrane treatment, evaporation of concentrated reject, salt separation and the return of recovered water. CEMCOT records project completion in March 2013.
Read CEMCOT’s SIDCO Phase II projectPernambut, Tamil Nadu
A ZLD project for the Pernambut tannery cluster, combining upgrades to effluent treatment, ultrafiltration and reverse osmosis, evaporation, and pipelines to return recovered water to tanneries.

OUR KEY INDIA PARTNER
Project design, community engagement and needs assessment in India.
Led by Dr. Nisha Priya Mani, Verdure Environmental Foundation is our key India partner for project design, community engagement and needs assessment. Together, we shape projects around local environmental conditions and the priorities of the people who will use and maintain them.
Dr. Nisha also serves as SIV Impact’s Head of Operations, India, connecting environmental science with local project delivery.
Visit Verdure Environmental FoundationSIV’S DELIVERY ROLE
Review the water source, demand, intended use and site conditions. Agree the project boundary, delivery responsibilities and performance measures.
Develop the technical approach and budget. Coordinate with public agencies, utilities and site teams on access, operating needs and required approvals.
Manage the agreed delivery scope with specialist partners, coordinate installation and testing, and establish handover responsibilities.
Agree who operates the system, how it is maintained, and how flows, water quality and performance are recorded and reviewed.
MEASUREMENT
Source, treated and reused volumes, with clear boundaries for any replenishment calculation.
Testing appropriate to the source and intended use, with a defined sampling and review schedule.
System availability, maintenance records and operating resource use where included in the project scope.
The project scope establishes the baseline, measures, reporting schedule and any independent verification requirements. Targets and measured outcomes are reported separately.
RELEVANT PROJECTS
Water stewardship / Chennai, India
Treatment tanks and ultrafiltration equipment installed for a modular sewage reclamation project. Trial runs and commissioning were in progress in the September 2026 update.
Water stewardship / Chennai, India
A program combining nature-based wastewater treatment, reuse and rainwater harvesting, with a planned reach of 15 government schools.
WHY SIV
Our water work brings together water policy, engineering, environmental science, project delivery and coordination with government agencies and utilities.
Enterprise leadership helps us connect the project to business decisions, budgets and accountability. Local coordination aligns technical partners, communities and public agencies around the agreed work.
We build cost discipline into scope, design, procurement and delivery, and consider ongoing care from the outset.
Meet our teamOUR WATER GOAL
Our company-wide goal is 1 billion litres of cumulative water replenishment by 2030. It is a cumulative ambition, not an annual volume or a result achieved to date.
Project design capacities and annual project targets are presented separately. Actual water benefits depend on monitoring and the agreed project accounting method.
