rejuWATER® – The World’s Most Natural Sewage Treatment Plant
Why We Need a Better Way to Treat Wastewater
-
Conventional STPs Are Broken
-
Use electricity, chemicals & pumps
-
Require skilled manpower
-
Produce toxic sludge
-
High OPEX & frequent breakdowns
And worst of all — they often fail and let untreated sewage enter soil and water bodies.
rejuWATER® Works With Nature, Not Against It
The Secret? Microbes, Soil, and Sunlight
rejuWATER® is a biomimicry-based STP that doesn’t use mechanical components or energy. Instead:
-
growRITE® soil hosts billions of beneficial microbes
-
Reed plants inject dissolved oxygen into the system naturally
-
Sunlight drives evaporation and oxygen exchange
-
Bio-conversion transforms sewage into usable water
Core Advantages of rejuWATER® STP
rejuWATER® STP harnesses the power of gravity, soil and sunlight to treat sewage. Modular, low-maintenance and 100% natural.
100% decentralized – no big sewage conveyance needed
~No power, motors, or moving parts
~Zero sludge generation
Consistent high-quality recycled water
Very low operating cost
Operates 24/7 – sun or rain
Foxconn Labour Camp, Bangalore
Problem: Unreliable STP with sludge problems
Solution: Portable rejuWATER® STPs
Result: Fully decentralized, portable, maintenance-free solution
Prakriya Home, Bangalore
Problem: Rooftop space unused & water crisis
Solution: Installed STP on roof; water recycled for flushing
Result: Fully self-sufficient home in terms of flushing water
Adhyapana School, Madurai
Problem: Groundwater depletion & high sewage conveyance cost.
Solution: Two 10 KLD rejuWATER® units at septic tank outlets
Result: 20,000 L/day reused for flush and gardening
Where It’s Working – Real World Projects
How rejuWATER® STP Works (Step-by-Step)
Raw sewage enters settling chamber or septic tank
Settled water enters rejuWATER® bio-bed filled with growRITE® soil.
Soil microbes digest organic matter. Reed roots oxygenate the soil, enabling aerobic breakdown
Clean water percolates and is collected for reuse
Easy to Install, Easier to Maintain
~Zero electromechanical components
Can retrofit existing septic tanks
Modular – from 1 KLD to 500+ KLD
No smell, no noise, no sludge removal
Ideal Applications for rejuWATER®
Independent Villas
Reuse flushing water from STP
Schools & Colleges
Recycle wastewater for gardens & toilets
Labour
Camps
Avoid tankers & sewage conveyance
Resorts & Ashrams
Sustainable onsite water reuse
