1. Bhavyas Anandam is an apartment complex, having 500+ apartments, located in Nizampet Main Road, Hyderabad. The Residential Welfare Association (RWA) of Bhavyas Anandam took technical guidance on bore well recharge technique from WLF team and implemented 6 such structures to existing dry bore wells during May 2015. Rain water from 100,000 sq. ft of its roof area is harvested to recharge to these bore well recharge structures. The RWA and the apartment residents immensely benefited in the form of increased water levels, water yields from bore wells and reduced water bill for buying private tankers.

2. The RWA of Divyaprabha Enclave, located on the Nizampet Main Road, Hyderabad, got motivated from the success of Bhavyas Anandam and implemented a dual system of rain water harvesting in their premises during Oct 2015. Water from its roof of around 25,000 sq.ft is harvested into a storage tank of 1 lakh litres for domestic use. In addition, all the rain water falling in its premises (around 1.8 acres) is tapped to recharge a dry bore well using the innovative bore well recharge technique. There is a remarkable improvement in the water yield from the bore well and residents could overcome water shortages.

3. A small apartment in Sanath Nagar implemented roof-top rain water harvesting and ground water recharge with technical guidance from WLF team. The rain water from around 5,000 sq.ft roof area is tapped using PVC pipes. There was space constraint within the premises to go for a recharge pit. The bore well location is closer to the apartment pillers. To avoid any possible damage with the pit made for bore well recharge method, a new technique is adopted here. This rain water is filtered using ‘Purain Filter’, a ready-made filter manufactured in Germany. The filtered pure water is fed into the existing bore well which is being used by the RWA for supplying water for domestic water needs to its residents.

4. A bore well recharge cum rain water storage system was implemented by SVD Arcades, Boduppal, Hyderabad. This small apartment with 12 families faced severe water problem during summer of 2015. The Flat Owners’ Association approach WLF team for overcoming the water problem. WLF team, during the visit, suggested constructing a two-way system of harvesting water–tapping rain water from 2000 sq. ft. roof and recharging the existing dry bore well and also storing the surplus rain water in the existing sump of capacity 1 lakh litres. This work done during Aug 2016 helped the association to tap copious rain during September and October months of 2016 and reduced the need for buying water in tankers.
5. Filter is an important component for any rain water harvesting system that captures rain water from roof-tops in urban areas. There are conventional systems of bucket / drum filters that require filling filter media (like sand, charcoal, pebbles etc.) in layers. There are very few off-the-shelf filter products in India now available for last few years. WLF team could install two products, Rainy Filter and another Purain Filter, so far. Here is a review and findings on Rainy Filter: http://www.indiawaterportal.org/articles/harvesting-and-using-roof-top-rainwater-part-2.
