Harvesting rain water the right way for your plot
Groundwater levels across much of Delhi NCR have fallen sharply, and most development authorities now require a rain water harvesting (RWH) system for buildings above a specified plot size as part of building plan approval. The threshold and format vary between authorities, so we check the applicable requirement for your project at the start.
A working RWH system is more than a pit in the corner of the plot. We calculate the roof catchment area and expected runoff, then design the collection pipes, a silt or filter chamber to keep debris out, and a recharge pit, trench or bore that suits the soil and water table. Where you want to reuse the water for gardening, flushing or cleaning, we add a storage tank with an overflow to the recharge system.
Location matters. The recharge structure should be away from building foundations and from septic tanks or other contamination sources, and reachable by the roof down pipes without long horizontal runs. On compact urban plots in Delhi, Noida or Ghaziabad, we often place it under the front setback or driveway with an accessible cover for cleaning.
For larger sites such as farm houses, schools and institutions, the system may combine several recharge points, paved area runoff and a larger storage tank. In every case, the drawings are prepared so they can be attached to your approval file and followed on site.

What the RWH design covers
Catchment assessment
Roof and paved areas measured to work out the collectable runoff.
Runoff calculation
Design runoff based on catchment area and local rainfall intensity.
Filter and silt chamber
A chamber that traps leaves and silt before water reaches the recharge point.
Recharge structure
Recharge pit, trench or bore sized to suit the soil and water table.
Storage for reuse
Optional storage tank with overflow to recharge, for garden or flushing use.
Approval drawings
RWH plans and sections in the format needed for plan submission.

What our clients say
"We handed over an empty 3BHK and got back a home that finally feels like us. The team listened to how we actually live — not how a catalogue thinks we should — and it shows in every corner."
"The modular kitchen is the star of my house now. Soft-close everything, a pull-out for my masala dabbas, and not a single wasted inch. My mother-in-law approves, which is the real 5 stars."
"What sold me was the 3D walkthrough — what I saw on screen is exactly what got built. No surprises, no 'arre sir yeh possible nahi hai' after booking."
