G.O. (Ms) No.70, Plugging of Sewage Outfalls in Chennai City, 2012
The Municipal Administration and Water Supply (Metro Water) Department issued G.O. (Ms) No.70, dated 26 July 2012, sanctioning Rs. 150 crore from the Infrastructure and Amenities Fund to the Chennai Metropolitan Water Supply and Sewerage Board. The funding is for the first phase of work to plug 337 sewage outfalls and strengthen Chennai City's existing sewerage system to prevent untreated sewage from entering waterways.
What the government approved
The Municipal Administration and Water Supply (Metro Water) Department, through G.O. (Ms) No.70, dated 26 July 2012, approved Rs. 150 crore in instalments for the Chennai Metropolitan Water Supply and Sewerage Board. The money comes from the State Infrastructure and Amenities Fund maintained by the Director of Town and Country Planning.
The sanction covers the first phase of a proposal to plug sewage outfalls and strengthen the existing sewerage system in Chennai City. The Budget Speech for 2012-13 had announced a wider proposal costing Rs. 300 crore to plug 337 outlets, treat the sewage and prevent untreated sewage from entering Chennai waterways.
Why the work was proposed
The Chennai Metropolitan Water Supply and Sewerage Board identified 337 sewage outfalls across three waterway systems:
- 105 outfalls in the Cooum river basin.
- 183 outfalls in the Buckingham Canal.
- 49 outfalls in the Adyar basin.
The proposal records that rapid urbanisation, vertical expansion and the conversion of individual houses into multi-storeyed buildings had placed pressure on existing sewer infrastructure. Untreated sewage was reaching waterways because of sewer capacity constraints and system malfunction, even though the former Chennai City area was covered by a sewerage system.
Work covered by the funding
The Chennai Metropolitan Water Supply and Sewerage Board classified the proposed sewer improvements into the following categories:
- Laying interceptors.
- Enlarging sewage pumping mains.
- Constructing roadside pumping stations.
- Improving existing pumping stations.
- Enlarging sewer mains.
Detailed project reports were being prepared, and the Chennai Metropolitan Water Supply and Sewerage Board was responsible for carrying out the work on priority.
Relevance to property owners and buyers
G.O. (Ms) No.70, dated 26 July 2012, is a public infrastructure funding sanction.
