Tadoba, Nagzira to develop waste water disposal system
NAGPUR, Thursday 22nd December 2011

 

 The Tadoba-Andhari Tiger Reserve (TATR) in Chandrapur and the Nagzira wildlife sanctuary in Gondia are developing an environment-friendly system for disposal of waste water for rest houses and staff quarters.

The 'Phytorid' wastewater treatment technology will be procured from the National Environmental Engineering Research Institute (NEERI), Nagpur.

Field director & chief conservator of forests (CCF) of TATR, VK Sinha, said a team from NEERI's environment material division (EMD) will visit TATR on December 24 and 25, for site inspection.

"As per the directions from principal secretary (forests) Praveen Pardeshi, we are creating an environment-friendly model to treat sewage water," Sinha stressed, adding, "The sewage water entering into the forests spoils its virginity and puts pressure on the ecosystem."

Conservator of forests (wildlife) Gondia M Srinivasa Reddy said he has approached NEERI to implement a similar technology for its rest houses like 'Nilay' and Loghut.

"Using wastewater technology is part of our new ecotourism guidelines. In phase II, it will also be implemented at guesthouses near Navegaon National Park," Said Reddy.

The TATR is already using Neeri-Zars, portable instant water purification system developed by NEERI, for its protection huts. Dr Rajesh Biniwale, principal scientist with NEERI's environment material division, said, 'Phytorid' technology is a cost-effective, environmentally-friendly method for treating sewage and wastewater.

"The technology is based on filtration and treatment capabilities of specific plants, which are cultivated in a plot or cement chambers created in case of bathroom or urinal water. Wastewater and sewage is then directed towards these tanks where the plants treat and filter the waste by removing pollutants," said Biniwale.

"Although a site inspection of TATR has not been done, we expect daily disposal of 2,500 litre waste water there. Cost for a 5,000 litre unit costs Rs 3.5 lakh, and the recurring cost is very less. The first unit set up in 2005 in Mumbai University campus, Kalina, has shown envisaged results," he said.
