CITY SANITATION PLAN BAREILLY
Alandur municipality had no underground sewerage system. Households had either septic tanks or
holding tanks, and the municipality was responsible for collecting the sewage periodically in tankers and
disposing it off in low-lying areas. To address these problems, an underground sewerage system was
designed for its current population, as well as for an estimated population of 3,00,000 in 2027, with the
objectives of improving the standard of living of the residents; providing for disposal of sewage through
an exclusive drainage network; avoiding recurring expenditure on septic tank cleaning; and preventing
groundwater contamination.
Implementation
In 1997, the Government of Tamil Nadu decided to provide a sewerage system in 12 selected major
urban centers including Alandur, in the context of a World Bank Project. The Chairperson of
Municipality, Mr. R. S. Bharati, took up the task of implementing this. It was decided that Tamil Nadu
Urban Infrastructure Finance Services Ltd. (TNUIFSL), the state asset management company, be
approached to finance the sewerage scheme. Considering the lack of financial and technical resources at
the municipal level to undertake such an infrastructure project, it was decided by TNUIFSL that the
municipality would undertake the project on a BOQ (Bill of Quantities) basis. The sewerage treatment
plant (STP) would be built on a BOT (Build, Operate and Transfer) basis. The project entailed a)
construction of an underground sewerage scheme with a network of sewer pipelines and manholes, of
120 kms (including 19 km main and 101 km branch lines); b) construction of a pumping house and
installation of pumping machinery; and c) construction of a sewage treatment plant with a capacity of
24 MLD (2 units 12 MLD each) on BOT basis to IVRCL and VATec for a period of 14 years.
The project work was carried out in two phases. In the first phase (the first two and a half years), 50% of
the branch sewers, main sewers, pump house including installation of machinery, pumping main and
one 12 MLD capacity sewage treatment plant, were completed and commissioned. The remaining work
relating to the project was to be carried out in the next phase. The particular challenges addressed were
communication and consultations with citizens to secure their buy-in and contribution to the sewerage
scheme, technical bottlenecks such as realignments necessitated by the construction of subways and
