Ducks are quacks to treat sick water in Mysore

Small wonder

Hundreds of swimming birds brought from Vellore are wallowing in sewage at one of the three ponds at the sewage treatment plant (STP) on Old Kesare here, in an experiment to break up solids in the sewage to make it easy for the plant to treat the sullage.

As the birds swim through the water, the waste floating atop is churned and breaks into smaller particles and is deposited at the bottom as silt.

Successfully experimented in Tamil Nadu, using ducks in the sewage treatment is being tried for the first time in the State, in Mysore.

As many as 752 ducks, supplied by a Tamil Nadu agency specialising in treating water using water fowl, have been released into one of the three ponds at the plant here, and more are expected to join them in the coming days. Fresh fish and other meat are the dietary requirements of the ducks, and the environmental engineers at the City Corporation have directed to arrange the supply.

Sources told Deccan Herald that the MCC spends close to Rs 12 lakh in the form of electricity bills comprising all the three STPs -- Vidyaranyapuram, Rayankere and Old Kesare.

For the last plant alone, the civic body pays the bill in the range of Rs 1.75 lakh to Rs 2.30 lakh.

It has a capacity of storing 30 MLD of water.

The wings of the fans in the bottom fixed to 24 motors, rotate swiftly, churning the water, and in the process, cleaning it.

The motors are switched on depending on the water received at the STP. From the minimum of six to a maximum of 16 motors are run round-the-clock.

Commissioned in 2002, the STP is the only non-chemical facility to treat water. The ponds are divided into primary and secondary storage. After secondary stage, the treated water is released into a valley nearby, that is used mostly for gardening and agriculture purposes.
