Conclusion
Impact Summary
The Bengaluru Airport rejuWATER® installation is a flagship example of resilient green infrastructure. While other STPs falter under complex conditions, this project stands strong - quietly treating 150 KLD of wastewater every day for five years straight. It reinforces the airport’s position as a global leader in sustainable operations.
Testimonial
"Bengaluru Airport’s rejuWATER® system is proof that sustainable infrastructure can be efficient, elegant, and self-sustaining. It just works—quietly and consistently."
— Facility Manager, KIA (CISF Camp)
The Results
✅ Over 54.75 million litres of sewage recycled annually
✅ 85% cost savings over a 10-year span
✅ Payback period under 2 years
✅ Zero breakdowns or operator intervention for 5+ years
✅ Supports airport-wide green infrastructure and IGBC certification goals
The Solution
RITEWAYS installed a rejuWATER® Soil BioFiltration STP with a 150 KLD capacity that runs on just 40 units of electricity per day. Built to work without moving parts, chemicals, or skilled manpower, the STP was designed for hassle-free operation and long-term durability. It treats wastewater naturally through soil, sunlight, and beneficial microorganisms, delivering high-quality treated water fit for flushing and landscape irrigation.
The Problem
As one of India’s busiest aviation hubs, Kempegowda International Airport (BLR) near Devanahalli handles massive footfall and generates significant quantities of sewage, particularly from its CISF camp and support facilities. Conventional STPs are often energy-hungry, complex to operate, and require constant maintenance. The challenge was to implement a reliable, low-footprint, low-maintenance solution that aligned with the airport’s aggressive sustainability goals—without compromising operational efficiency.
