Bring ponds back.
Keep them alive.
Testing, desilting, sewage interception and natural treatment that turn silted, polluted ponds and lakes into clean, working water bodies, backed by our own laboratory.
ENGINEERED WITH PURPOSEWater. Environment. Circularity.
Why it matters now
India's ponds store water, recharge wells and cool towns.
Most of India's water bodies are small ponds in villages and towns. Many are silted up, choked with weeds or fed by untreated sewage, so they hold less water and recharge less groundwater. National programmes now fund their revival, and cities, industries and campuses are restoring ponds on their own land.

Challenge and response
Why revived ponds often decline again.
- 01The challenge
Sewage and drain water keep flowing in after desilting.
How we solve itIntercept and treat inflows before they reach the pond.
- 02The challenge
Silt returns with the first heavy rain.
How we solve itSilt traps and stable, planted banks at every inlet.
- 03The challenge
Algae and water hyacinth take over within a season.
How we solve itCut the nutrients that feed them, then aerate and plant.
- 04The challenge
No one checks water quality after handover.
How we solve itScheduled testing by our laboratory and a clear upkeep plan.
What we deliver
Six services, one team.
Stop polluted inflows
Deal with the cause, not just the symptoms.
- Drain diversion and interception
- Screens and silt traps at inlets
- Compact STPs or natural treatment for inflows
Desilting and reshaping
Give the pond back its depth and storage.
- Planned desilting and silt disposal
- Bund and bank strengthening
- Gentle, stable side slopes
In-pond natural treatment
Improve water quality inside the pond.
- Aeration and fountains
- Bioremediation with microbial cultures
- Floating wetlands and native plants
Green edges and recharge
Help the pond feed groundwater and wildlife.
- Constructed wetlands at the margins
- Recharge structures where suitable
- Native planting on banks
Monitoring and upkeep
Keep the pond healthy after handover.
- Seasonal water quality testing
- Weed and silt management
- Operation and maintenance contracts
How we work
How we deliver, from first sample to a living pond.

- 2
Plan
Inflow control, desilting and treatment design.
- 3
Restore
Interception, desilting, banks and planting.
- 4

Seasonal monitoring and upkeep.
Standards and regulations
Designed to the standards that apply to your water body.
We set clear water quality targets for each pond based on how it will be used, and test against them.
- CPCB water quality criteriaTargets by designated best use, such as bathing or wildlife.
- IS 2296Classes and limits for inland surface waters.
- Mission Amrit Sarovar guidelinesDesign and upkeep norms for revived water bodies.
- Wetlands (Conservation and Management) Rules, 2017Rules for notified wetlands and their surroundings.
- Environment (Protection) Rules, 1986Limits for any treated water discharged to the pond.
Where it fits
Built for the places that depend on it.
- Village panchayats and Amrit Sarovars
- Municipal lakes and urban ponds
- Industrial campuses and parks
- Hotels, resorts and campuses
- Temple tanks and heritage water bodies
Why Rispri
One accountable partner, from lab bench to living pond.
Lab and engineering under one roof
Our accredited laboratory tests the pond before work starts and proves the improvement after. No hand-offs between vendors.
Treatment expertise since 1999
The same team that designs ETPs, STPs and natural treatment systems plans how to keep polluted inflows out of your pond.
Causes fixed, not hidden
We stop sewage and silt at the source, so the pond does not slide back after one monsoon.
We stay after handover
Seasonal testing, weed and silt management, and upkeep contracts keep the pond healthy for years.
Questions
Frequently asked questions.
Does the pond have to be drained?
Not always. Desilting is easiest when the pond is low or dry, so it is usually planned for the dry season. Water quality work such as aeration, bioremediation and floating wetlands can be done with water in the pond.
Can you remove water hyacinth for good?
Removing it is the easy part. It comes back if sewage and fertiliser keep feeding the pond. We remove the weed and cut the nutrients that feed it, then keep an eye on it through the season.
How do we know the pond has really improved?
Our laboratory tests the water and sediment before work begins and again after restoration, against targets set for how the pond will be used. You get the results in a report.
Can a pond on our campus help with groundwater?
Often yes. A restored pond with recharge structures, where the soil allows, can help replenish groundwater. We assess the site first to see what is practical.
