Rajahmundry, June 30: The people of Rajahmundry are going to get major relief from the overflowing and stinking drains and inundation of several low-lying areas during rains as the civic authorities are going to take up an underground and storm water drainage network in the municipal limits. The project would cost Rs 225 crore to be taken up under Urban Infrastructure Development for Small and Medium Towns and to be funded by the Centre. A majority of the drains in the city overflow and drain water enters into the habitations located in the low-lying areas causing hardships to the inmates to save their belongings from the drain waters. The existing drainage network fails to take the full capacity to drain out the city during the rains. The open drains with stagnated water in certain pockets serve as breeding grounds to mosquitoes. To sort out this problem, the civic authorities roped in a private consultancy to carry out a survey to provide complete underground drainage network in the city. The civic authorities earlier took up the underground drainage network as a pilot project in some pockets of Prakashnagar and Danawaipeta. But it is not in use at present. The proposed underground drainage network could be lined up with the upcoming one. As per the consultancy report, the underground drainage network would be taken up at a cost of Rs 150 crore. Laying of distributory sewers was estimated to cost nearly Rs 100 crore. In addition to the existing sewage treatment plant, an additional 40 MLD plant at Hukumpeta and another 10 MLD plant at Kateru are going to be constructed. Once the plants become operational, releasing of untreated drain water into the Godavari ca-using pollution to the river water could be stopped. Similarly, storm water drains are also coming up at a cost of Rs 75 crore. Beginning at Korukonda road and touching Kateru, there will be an outlet into the river at Mallaiapeta.
