Rainwater Harvesting at Goa University

How Goa University Secured 7.87 Lakh Litres of Rainwater a Year

Institutions across Goa are facing growing water stress—Goa University included. With unreliable groundwater and rising water needs, a sustainable solution was essential. In 2018, under Nestlé’s CSR partnership, AlterEnergyZ implemented a turnkey rainwater harvesting system that now captures 2,62,500 litres per month (totaling 7,87,500 litres annually)—boosting water resilience across campuses.

• Annual: 7,87,500 L
• Components Mentioned (withheld details): The system includes roof catchment, a first-flush device, preliminary settlement, and multi-layer filtration before recharge to an 80-metre borewell

How Rainwater Harvesting Adds Long-Term Value

Rainwater harvesting isn’t just about collecting rain — it’s about designing a system that delivers measurable impact, year after year.

From reducing tanker dependency to improving groundwater levels and meeting compliance norms, a well-executed harvesting system helps your institution stay resilient, responsible, and audit-ready.

At AlterEnergyZ, we customise every project to the site’s needs — ensuring maximum recharge, minimal maintenance, and long-term water security for your campus.

What Government Policies Say About Rainwater Harvesting

The Goa government actively supports rainwater harvesting — offering subsidies of up to 50% for approved systems. Despite receiving over 2,500 mm of rainfall annually, institutions still face dry-season shortages due to runoff and lack of recharge.

That’s why campuses, hospitals, and government buildings are increasingly required to implement sustainable water systems. Investing now means staying ahead of mandates — while securing your water supply long-term.
