RFQ Code: WFL-RFQ-002

THEME: Water Conservation & Climate Resilience

SDG GOAL: SDG 6 – Clean Water and Sanitation

ABOUT THE PROJECT: In response to growing water scarcity driven by rapid urbanisation and excessive reliance on groundwater, the Percolation Well Project aims to improve groundwater recharge through scientifically designed rainwater harvesting structures. These wells are constructed in public spaces such as schools, hospitals, and government campuses, where they enable rainwater to seep into the ground, replenishing shallow aquifers. By capturing runoff and allowing it to percolate, the project enhances local water availability, supports ecological balance, and contributes to long-term water security in urban and semi-urban areas.

SCOPE OF PROJECT: 
1. Construction of percolation wells with standard dimensions to ensure effective groundwater recharge
2. Use of concrete rings and pre-cast slabs to structurally reinforce the well and maintain durability
3. Layering of 40mm jelly stones to aid water infiltration and stabilize the internal structure
4. Installation of protective safety grills to prevent accidents and ensure public safety
5. Engineered to direct rainwater deep into the soil for aquifer recharge, reducing surface runoff
6. Ideal for areas with low soil permeability or frequent urban water stagnation and flooding

IMPACT:
1. Each percolation well has a storage capacity of 42,700 liters, allowing significant water retention per recharge cycle
2. Annual groundwater recharge potential of up to 4 lakh liters per well, based on local rainfall patterns
BENEFICIARIES: Local population
