Rainwater harvesting · Gurugram
Rainwater harvesting in Gurgaon (Gurugram)
TerraSetu is based in Gurugram and builds rooftop rainwater harvesting and recharge systems across the city: filter chambers, recharge pits and recharge bores for houses, builder floors, housing societies, offices and factories. Gurugram pumps out 195% of the groundwater that can safely be taken out each year, and the Haryana Building Code makes recharge compulsory for most buildings, so a working system is both the law and the cheapest water insurance a building can buy.
Why Gurugram needs it
- The Central Ground Water Board puts Gurugram's groundwater use at 195% of what can safely be taken out (2025) and rates the district over-exploited. See the groundwater page for Gurugram.
- In CGWB's pre-monsoon readings, most monitoring wells in the district have water 20–40 m below ground, and the deepest 40.2 m (132 ft). See the water table page.
- Gurugram gets about 721 mm of rain in an average year, 81% of it from June to September. A 100 m² roof can put about 61,285 litres a year back into the ground.

Ranges for budgeting, with filter chamber, pit, media, bore and piping. A site survey fixes the design and the price. See every building size and bore depth on the rainwater harvesting cost page for Gurugram.
How we build it
Survey
We measure the roof and paved areas, trace the downpipes and drains, and check the soil and any borewell on the plot.
Design
A drawing with the number and position of recharge points, sized for Gurugram's rainfall, and an item-wise quote.
Filter and pit
Downpipes are joined into a filter chamber of gravel, charcoal and sand with a first-flush diverter, leading to a brick-lined pit filled with boulders, gravel and coarse sand under an RCC cover.
Recharge bore
A 150 mm bore with slotted PVC casing in the pit floor, about 120 ft deep in most of Gurugram, so the water reaches the layers your borewell draws from.
Handover
Photos of every stage, an as-built drawing and a cleaning schedule, which is what the occupation certificate file needs.
The rules in Gurugram
Under the Haryana Building Code, 2017, every building with a roof of 100 m² (about 1,076 sq ft) or more must harvest its roof rainwater inside the plot, and DTCP does not issue an occupation certificate without rainwater harvesting pits. The same code applies in HSVP sectors and MCG areas.

Fixing an old system
Many pits in Gurugram were built only to get the occupation certificate and have not been cleaned since. Silt seals the sand layer and the pit overflows into the drain at the first heavy rain. We desilt the pit, replace the filter media, flush or re-drill the recharge bore and add a silt trap so it keeps working.
Where we work
All of Gurugram: the DLF phases, Golf Course Road and Golf Course Extension, Sohna Road, the New Gurgaon sectors along Dwarka Expressway and NH-48, Udyog Vihar, Manesar, Sohna, Pataudi and Farrukhnagar. We also work across Delhi, Faridabad, Noida and the rest of Haryana.

Frequently asked questions
How much does rainwater harvesting cost in Gurgaon?
For an independent house with a 100 m² roof, about ₹1.1 lakh to ₹1.7 lakh with GST for one recharge point with a 120 ft bore. Housing societies, schools and factories need several points; see the table above.
Is rainwater harvesting mandatory in Gurgaon?
Yes, for every building with a roof of 100 m² or more under the Haryana Building Code, 2017, and DTCP does not issue an occupation certificate without rainwater harvesting pits.
Who installs rainwater harvesting in Gurgaon?
TerraSetu is a Gurugram engineering firm that surveys, designs and builds rooftop rainwater harvesting and recharge pits for houses, societies, offices and factories, and repairs old pits that have stopped working.
Can you repair our society's rainwater harvesting pits?
Yes. We inspect every pit, desilt it, replace the filter media, flush or re-drill the recharge bore and give the society a report with photos and a cleaning schedule.
Does rainwater harvesting help my borewell?
A recharge bore puts filtered roof water into the same layers a borewell draws from, which slows the fall of the water level around it. See borewell recharge in Gurgaon.
