Legislation on Rainwater Harvesting in Port Blair
In 2007, Port Blair Municipal Council (PBMC) directed all the persons related to construction work to provide a proper spout or tank for the collection of rain water to be utilised for various domestic purposes other than drinking. As per the existing building by-laws 1999 the slab or roof of the building would have to be provided with a proper spout or gutter for collection of rain water, which would be beneficial for the residents of the municipal area during water crisis. The PBMC had advised all the owners of buildings in the Municipal area to comply with the provisions within four months failing which action would be taken against them by the Council.
