Even though hidden from view the sump tank has an important role to play in the use of a building. A good design and maintenance will help extend its life and for it to perform optimally. In this understanding lies water wisdom.

 

The ideal system in Bangalore is one where rainwater is stored in sumps and the surplus used for recharging borewells.

 

===Costs===

A tanker load (in Bangalore) of 6000 litres costing about Rs 200/-. To store water during construction, sumps were built and these would also be 6000 litres so as to fill up a tanker load completely. Coincidentally this happened to be the exact optimal storage requirement for rainwater harvesting. This made it easier for implementation using the sump as storage<ref>[http://www.rainwaterclub.org/docs/Domestic_Rainwater_Harvesting.pdf Domestic Rainwater Harvesting, Some applications in Bangalore, India]</ref>.
