With the work on executing the phase-II of the underground drainage (UGD) scheme picking up momentum in the city, Tiruchi Corporation plans to start providing new sewage connections to a part of households in the left-out areas within the next six months.
Unlike phase-I of UGD project that took almost seven to eight years for the civic body to complete works, the phase-II project, estimated at a cost of ₹344 crore, has been divided into three packages for expeditious completion.
While Ancher Ceramic Company Private Limited, Chennai, which bagged the package-2 contract, has already started construction works, the civic body issued work orders to Subaya Constructions Company Ltd, Chennai and Eco Protections Engineers Private Limited, Chennai, for the packages 1 and 3 respectively. They are expected to start the works within a few weeks.
As far as the works of package-2 are concerned, officials claim that it is progressing at a good pace. The work is scheduled to be completed by June 2021. Already 15 % of the works have been completed.
100 workers, engineers
A total of 100 workers and engineers have been engaged in the construction works in Viswas Nagar, Mahalakshmi Nagar, Dhanaratnam Nagar, Annamalai Nagar, Sanjeevi Nagar, Devadhanam, Raja Colony and others. Construction of 2827 manholes and 13 lifting stations, laying of pumping main for 12.24 km and sewer line for 66.55 km are among the important components of the works.
As on Tuesday, out of 2,827 manholes, 821 have been constructed. Laying of sewer line has been completed for 10.4 km.
Instead of taking up works in different locations, which was the feature during the phase-I UGD works, the contracting company has been tasked to complete one area after another. The workers move to other areas only after completion of all works in a particular area.
Moreover, the internal plumbing works, which had to be taken up by the individual households while connecting with the phase-I of UGD network, are being done by the contractor.
“If the current pace is sustained over the next few months, we will be in a position to start providing new UGD connections to the households within six months. There is no need for waiting for completion of the entire project as the pumping mains are being connected to the existing drainage network in the city,” said N. Ravichandran, Corporation Commissioner, after inspecting the progress of works at Devadhanam.
