BWSSB To Start Campaign On Rainwater Harvesting

BWSSB To Start Campaign On Rainwater Harvesting
The Times of India

Bangalore: Two years after the government made rainwater harvesting techniques mandatory for new constructions, the civic authorities at last seem to have realised the importance of water conservation. Especially, in the light of the Greater Bangalore concept being considered for implementation.
The BWSSB is kicking off a campaign to create awareness about rain harvesting techniques. The campaign, mooted by BWSSB chairman N C Muniyappa, comprises modules which can be easily installed in houses. The BWSSB will introduce four modules — rooftop harvesting, open space harvesting, natural storage and ground water recharge. The benefits of rain water harvesting are availability of fresh water, reduction in dependency on conventional water supply, reduction of soil erosion and no flooding in lowlying areas, increase in ground water availability and prevention of rainwater from gushing into underground drainage.
Among the four modules, rooftop rain harvesting is the easiest and viable option. It involves installation of PVC water pipes used for chanelising rain water collected on the rooftop. For filtering the water, sand bed or pop-up filter can be used and harvested rainwater can be stored in masonry/ferro cement/plastic tanks. The capacity of storage device can be decided by parameters such as rood area, water usage and space availability. The cost of rain water techniques varies from Rs 2,000 to Rs 50,000 per house depending on the requirements.
Whom to contact to know about the modules? The BWSSB will also put out a list of the officials and recognised firms dealing with water conservation. Those interested in the project can contact BWSSB public relations officer on 22945114.
