Sanitary sewage treatment scheme is a long perceived need in Digha. There is nocentralized sewerage system in the region and stand-alone systems (septic tank with soak pit)do not work very well in this region owing to high water table. Being a tourist area (withabout 300 hotels), sewer load generated in this region is high and fluctuating. Well plannedcentralized sewerage system is one of the major building blocks for implementation ofIntegrated Coastal Zone Management Plan in the region.201. The first plan of sewage treatment scheme was prepared by Planning Circle I, PHE atan estimated cost of Rs.244.27 lakhs. This was revised again in 1996 to bring someadditional areas under the purview of the scheme with an estimated cost of Rs.409 lakhs.The scheme was taken up for execution in 1997. After a portion of sewer line was laid, workwas suspended due to sand boiling at 1.45m (R.L.). This necessitated further review of thescheme. Revised scheme was prepared again with due consideration to the following points.to restrict sand boiling problem during laying of sewer line.ground water infiltration @ 5000 litres / hectare / day.the rate of per capita water supply at 125 litres / day.202. Based on the re-design, the suspended work was resumed in 2000 and laying of 6496metres of different diameter sewer line and 1248 metre of different diameter pumping main.One main pumping station and 4 sewage lifting stations were also constructed within thesanctioned of Rs 409.00 lakhs against the estimated re-designed cost of Rs 457.41 lakhs.Work has remained suspended since then due to lack of fund.
