Rainwater Harvesting – Save Water. Recharge Ground. Reduce Cost.

Why Rainwater Harvesting is Critical?

  • Chennai depends heavily on groundwater & tanker water

  • One heavy rain = lakhs of litres lost to drains

  • Borewells fail not due to usage, but no recharge

  • RWH is mandatory, but mostly done wrong or left unused

Our goal: Practical rainwater harvesting that actually works — not paperwork systems.

What we Offer

We design working rainwater harvesting systems, not just pits.


  • Rooftop rainwater collection systems

  • Borewell & open well recharge

  • Recharge pits & percolation trenches

  • First-flush & filtration systems

  • Inspection, correction & upgrades of existing RWH systems


Suitable for homes, apartments, commercial buildings & industries.


How Much Water Can You Actually Save?

Example

  • Roof area: 1,000 sq.ft

  • Annual rainfall (avg): 1,200 mm

  • Water harvested/year: ~75,000–90,000 litres

That’s:

  • 5–6 months of domestic water

  • ₹30,000–₹60,000 saved per year (tanker cost)

Common Problems We Fix

  • Pit exists but no water recharge
  • Filter clogged, nobody cleans it

  • Borewell still dry after RWH

  • Water overflowing to road

  • Builder-made system for name sake


We inspect → correct → make it functional


Our Approach

  • Site inspection (roof, slope, soil, borewell depth)

  • Right pit size (not generic)

  • Proper filter & first-flush

  • Easy maintenance design

  • Photo & layout documentation


No over-engineering. No fake promises.

How it works

Rainwater from rooftops is collected through downpipes, cleaned using a first-flush and filter, and safely directed to recharge borewells, open wells, or recharge pits.

Result:

  • Improved groundwater levels
  • Better borewell performance
  • Reduced tanker water usage

Every working rainwater harvesting system helps improve groundwater for the entire neighbourhood.

We also support schools, NGOs and few projects with cost-effective designs.

Borewell & Rainwater Sediment Removal Tank – Key Benefits

  • Removes sand, silt, and sludge from borewell and rainwater before storage
  • Acts as a pre-cleaning sediment tank to protect sump and overhead tanks
  • Conical bottom design allows easy sediment settling and flushing
  • Bottom drain enables quick sludge removal without manual cleaning
  • Reduces pump damage, pipe choking, and frequent tank cleaning
  • Ideal for borewell water users, rainwater harvesting systems, villas, apartments, and farmhouses
  • Best used as a first-stage settling tank before main water storage
