A 10 meter deep recharge pit is dug adjacent to the primary borewell in the park area. Rainwater from storm drains channeled into well.
Narrative
The design was done by Biome who got the contract to build the well.
After completion, a coincidental leak at the main borewell left a puddle of water for 3 days. Clearly, the clay soil absorbed little water. So, the permeability of the well and the ability of this recharge pit to actually absorb the rainwater and recharge the groundwater was also questioned.
Two tankers of water were hired to fill up the well (5000 liters) and the water stayed for over two days. Clearly, this well is not going to absorb the rainwater and recharge the groundwater.

Sustainability
Creating and measuring long-term impact
The well will need to be cleaned every season. LW maintenance funds will cover this. Considering its absorbtive capacity (lack of), cleaning may not happen.
Learnings
Knowledge of project and process for sharing
Do SLUG tests to see of soil will absorb water and how fast.
