Centre clears six STP projects for UP, Bihar under Namami Gange

New Delhi : The Centre has approved six sewage treatment infrastructure projects entailing an investment of Rs 414 crore in Uttar Pradesh and Bihar under the Namami Gange programme.

The six projects, along with another one for ghat development and research, have been approved by the executive committee of National Mission (NMCG) for Clean Ganga on July 31.

In Uttar Pradesh, interception, diversion and sewage treatment plant (STP) projects for Unnao, Shuklaganj and Ramnagar have been approved. These three projects aim at creation of sewage treatment capacity of 29 million litre per day (MLD).

While Unnao will get a 13 MLD sewage treatment plant, in Shuklaganj, a 6 MLD STP will come up and Ramnagar will get a 10 MLD one. The total cost of the three projects has been pegged at Rs 238.64 crore.

Likewise, in neighbouring Bihar, three projects at Sultanganj, Naugachia and Mokama with total estimated cost of Rs 175 crore have been approved.

These three projects will create additional sewage treatment capacity of 27 MLD. Sultanganj will get a 10 MLD sewage treatment plant, Mokama will have a 8 MLD and Naugachia will have 9 MLD plants to treat sewage.

All the six projects will be provided with operation & maintenance cost for 15 years by the Central Government and 100 per cent Central assistance. This will be done on the basis of his work performance on the achievement of desired norms of treated wastewater.

The Unnao and Sultanganj sewage treatment plant projects will be taken up under the hybrid annuity-based PPP (public private partnership) model, in which 60 per cent of the capital cost will be paid to the contractor who has constructed the STP over a period of 15 years.

Uttar Pradesh has emerged on top among the five main Ganga states in terms of ongoing sewage treatment infrastructure capacity being added. While ongoing STP projects in Uttar Pradesh will create 390 MLD of treatment capacity, 50 MLD is under tendering and another 72 MLD of treatment capacity has been approved.

An additional 158 MLD of treatment capacity has been proposed in the state, bringing the overall fresh capacity of 670 MLD.

Bihar has ongoing projects that would create 173 MLD and another 60 MLD approved. Another 319 MLD is proposed for the state.

The total sewerage generation in the five states as of 2016 was to the tune of 3520 million litre per day (MLD), which is expected to go up to 4648 MLD by 2035. But, total existing STP capacity in 43 towns across the five states is only 1480 MLD, or just over 42 per cent.

The treatment capacity gap in the five states was 2109 MLD in 2016, which is seen rising to 3192 by 2035.

In its meeting on July 31, the NMCG also approved a research study to understand the non-putrefying properties of Ganga in both water and sediment at an estimated cost of Rs 5 crore.

The study will be an extension of a research carried out by National Environment Engineering Research Institute (NEERI) to identify the special properties of the riverís waters. This research would focus on finding out the science behind these special properties in order to formulate a strategy to retain these characteristics.

Why forests should take centre stage during the water decade

Only a tiny fraction of national biodiversity plans consider the impact of forests on water supply, and only a fraction of national water plans place ecosystems at their centre.
