During the monsoon, temple tanks in Chennai fill to the brim with water, helping in groundwater recharge.

Besides showcasing the architectural expertise and aesthetics of their time, temple tanks also play an extremely important role as water storage systems in Chennai. Chennai has 39 temple tanks (excluding the suburban area) according to a study conducted in 2008.  As the rains arrived, a few temple tanks in the city were filled to the brim with water, thus helping in groundwater recharge while offering a spectacular view for devotees.

The only place for building rainwater harvesting structure within an apartment site is the stilt parking area with a 10 ft roof.  

Are there restrictions in building RWH structure of 3ft dia width and 10ft deep within the apartment stilt parking area in Chennai? With this type of recharge pit, we are apprehensive about whether all this water underground will affect pillars or the foundations of the construction? We do not have any other open area outside to build this recharge pit.

Hi,

Ours is a gated community with 160 apartments covered around 1.5 Acres in Thoraipakkam, OMR, Chennai. We digged borewell in our apartment. It was manual borewell and no machine used. Borewell guys stopped digging at 26 feet due to presence of salt water. We have placed rings around the bore but we are not sure if the borewell water received is the fresh water or its water seepage through subsoil. Some people here say its subsoil water seeping into the bore. We are able to find water even if we dig for 10 feet in our area. Please help us in this.

Thanks Barath
