Is rainwater harvesting mandatory in Gurugram?
Yes, for most buildings. Under the Haryana Building Code, 2017, every building with a rooftop of 100 m² (about 1,076 sq ft) or more must harvest its roof rainwater inside the plot, and the Department of Town and Country Planning (DTCP) does not issue an occupation certificate without rainwater harvesting pits.

Who must build it
| Building | Required? |
|---|---|
| House with a roof of 100 m² or more (most plots of 150 sq yd and above) | Yes, roof water into recharge pits inside the plot |
| Group housing on plots over 500 m² | Yes, roofs plus parks, roads and parking |
| Commercial, institutional, industrial and government buildings | Yes |
| Schools, hotels, farm houses and industries in Gurugram and Faridabad | Yes, also under earlier Central Ground Water Authority directions |
| Small house with a roof under 100 m² | Not required by the code, but cheap and worth it |
Why Gurugram is strict
Gurugram pumps out about twice as much groundwater as rain puts back: its stage of extraction was 195% in the 2025 CGWB assessment, which makes it over-exploited. In 2018 the typical well read 20 to 40 m below ground. See the Gurugram groundwater page and the water table in Gurugram.
Faridabad (175%) is also over-exploited. Nuh is lower at 72%, but its groundwater is salty and high in fluoride in places, see water quality in Nuh.
What a compliant system looks like
- All roof downpipes joined and led to recharge pits inside the plot, not to the road drain.
- A filter chamber or first-flush diverter before the pits.
- Recharge pits with recharge bores, sized for a heavy storm: see how to build a recharge pit.
- For group housing: silt traps on road and park drains, and pits spread across the site.
- An overflow to the storm drain, and access for cleaning.
Enforcement
The occupation certificate is the main check. After that, enforcement is weak: audits in Faridabad have found most pits defunct. A choked pit does nothing for your borewell, so clean the filter and top sand before every monsoon.
What it costs
For a typical house in Gurugram, a full recharge system costs about ₹1.1 lakh to ₹1.7 lakh with GST. See the rainwater harvesting cost in Gurugram for other building sizes.

Frequently asked questions
Is rainwater harvesting mandatory for a 250 sq yd plot in Gurugram?
Almost always. A 250 sq yd plot (209 m²) usually has a roof well over 100 m², which is the Haryana Building Code threshold, so recharge pits are needed for the occupation certificate.
Who checks rainwater harvesting in Gurugram?
DTCP checks it before the occupation certificate. For HSVP sectors and MCG areas the same building code applies. Industries and large users drawing groundwater also need a NOC with recharge conditions.
Can I use a storage tank instead of recharge pits?
The Haryana code asks for recharge. A tank for reuse can be added before the pits, with its overflow going to them.
