Chennai:
In a bid to achieve the goals of ensuring water security in the city, Chennai Metropolitan Development Authority is planning to conduct a detailed audit of rainwater harvesting system across Chennai by involving NGOs.
A CMDA sources told Express that a tender has been floated in this regard and the process would be finalized in the next 15 days.
Sources said that as per the development regulations of Chennai Metropolitan Development authority rainwater harvesting is mandatory in each premises. “We are likely to engage two NGOs who would be carrying out the audit across the Chennai Metropolitan Authority Area,” the sources added.
The plan is to carry out RWH audit though a network of NGOs pioneered in this field, sources added.
Interestingly, the rainwater harvesting structures installed during the AIADMK regime in 2003 has helped increase the ground water level in the city. As per a recent report, the ground water level and quality before July 2003 and after June 2011 has increased in the sandy, clay and rocky areas of the city. Sources also said that after implementation of RWH scheme, not only the quality of water improved but also large part of the fluoride content was also diluted .
Sources said the audit is expected to strengthen and streamline the system.
Rainwater harvesting is the process of augmenting the natural filtration of rainwater in to the underground formation by some artificial methods. There are various ways of rainwater harvesting, including collecting it from the roof of the house or building. It can either be stored in a tank or diverted to artificial recharge system. This method is less expensive and very effective.
CMDA sources said that rainwater harvesting is a prerequisite for obtaining plan approvals when new buildings are constructed. Even older existing structures have been mandated to build the structures
