In order to derive the benefits of the scheme continuously the residents are requested to maintain the RWH structures properly before the onset of Northeast monsoon. The materials filled in the filter chamber such as sand / pebbles/ blue metals are to be removed, cleaned with water and refilled with blue metal at the bottom, pebbles at the middle and sand at the top. In addition to this the rainwater pipes connecting the RWH structures shall be cleaned free from any blocks or cracks so as to avoid overflow/leak.
The public are advised to contact the respective Area Offices and Depot Offices of CMWSS Board for proper guidance on the maintenance of Rain Water Harvesting structures. The officials of CMWSS Board would inspect the houses/buildings to assess the conditions of Rain Water Harvesting structures. The public are requested to maintain the Rain Water Harvesting structures properly, for effective recharge of rainwater and thereby help to improve further the water table and its quality in Chennai city, which will benefit during drought /water scarcity periods.
For further details about the maintenance of Rain Water Harvesting structures, please contact the Rain Water Harvesting Cell of CMWSSB. Phone No.28454080 or visit Website www.chennaimetrowater.tn.nic.in.
