Underground sewerage scheme for Udumalpet town is finally to become a reality as municipal administration plans to commence the work on the project during the first week of May.

As per the latest estimates, the underground sewerage network will be laid at an outlay of Rs. 56.07 crore, covering the entire 33 wards in the municipality, spread over 7.41 sq.km.

“The commissioning of the facility has been tentatively set at March 23, 2015,” Municipal Chairman KK.G.S. Shobana told The Hindu.

The preliminary road surveying and related sundry jobs, leading to the commencement of the actual project works in the next few days, is under way in the town.

Though the project was conceived about five years ago, it did not take off for various reasons.

Explaining the salient features, Ms. Shobana said that sewer lines would be laid for total length of 96.96 km and designed to cater to a projected population of 90,301 in 2044. The present population of Udumalpet town, as per 2011 census, is 61,150.

Apart from laying sewers, a total of 3,983 manholes, sewer appurtenances, a sewage treatment plant and a lifting station will be constructed as part of the project.

The sewage treatment plant is planned at Senjerimalai road and the lifting station at Karunanidhi Colony.

Te sewage treatment plant has been designed to treat 9.03 mld (million litres per day) of waste water and excrement expected to be generated every day in 2044.

“During the initial days of commissioning, the plant will get a load of 6.75 mld of waste water and excrement and it will be treated using activated sludge process methodology,” official sources said.

According to Ms. Shobana, the scientific collection, treatment and disposal of sewage envisaged in the project will put an end to sewage finding its way to drains and polluting the underground water table.
