187indirectly to the Bay of Bengal and to the Canal besides Digha Bypass. The existing kachhadrains will be lined.230. The technical specifications are as follows:i) Type of drain – Brick built open type surface drainii) Base of drain – PCC 100mm thick to be laid on 1 layer of brick flat solingiii) Side walls – Brick masonry wall varying in thickness from 250 mm to 750 mm to beconstructed with burnt bricks having crushing strength 75 kg./cm 2 , bonded with sandcement mortar in 6:1 proportioniv) Finishing – The external surface and the top surface of the drain section will be finishedwith 20mm thick sand cement plaster in 1:4 proportion to be rendered with 1.6mm thickcement punning.231. So far the attempts to bring the entire city sewage of Digha Township under a STPhave not met with success due to level difficulties arising out of older dunes on which amajor portion of the Old Digha town had developed. During 2007-08 an attempt was madefor a pilot Bioremediation STP behind the Aparajita Cottages which was quite successful inreducing the BOD load and the outfall DO attained a concentration of 6.5 mg./l.232. Two numbers of aeration ditches in series will be created to have sufficient capacityto retain liquid wastes for 3 days with a buffer of 1 day. The outflow from the ditches will bemade to pass in 4 furrows intercepted by mangroveOne Storm W root zones which will actto reduce the septicity of water to the tolerance limit, through root zone absorption.The technical specifications as worked out are given below: Aeration ditches – 2 each of 3000 m 3 capacity Residence time – 3 days plus 1 day buffer Ridges and furrows – 4 each 0.9 m deep and 20 m long Clearing period – every 2 months Plants to be providedAeration pond – water hyacinth or duckweedFurrows – acanthus ilicifolius and sonneratia caseolarisRidges – minjiri (cassia siamea), eucalyptusCost233.

188Total (excluding cost towards electrical works, goods & equipment,operation & maintenance and monitoring & evaluation) 1493.72Component B.5 - Provision of grid electricity to Sagar Island234. Sagar Island depends on diesel generating sets for electricity requirement andelectricity is available for a part of the population on an organized scale only during theevening hours. However, during Sagar mela in January every year, power supply continuesthroughout evening and night hours.235. The existing distribution system comprises 20 no 11/0.433 K.V. distribution substationswith 44 km 11 K.V. feeder and 26 km M & L.V. lines catering power to domestic,commercial and industrial consumers. The inadequacy of power supply is at the root of anysubstantial developmental activities and livelihood upgradation/enhancements of theinhabitants. The immense possibilities of development of tourism, of multi-crop cultivationthrough energized withdrawal of ground water (without inviting saline water ingress) and offish preservation and processing could be realised with the availability of grid electricity.236. WBESDCL has already initiated on its own a project to connect Sagar island withgrid power available at Kakdwip 33/11 K.V. sub-station via Lot 8 (ckt-I) and GourangaMath (ckt-II) and a crossing over river Muriganga at Harwood point on towers to theproposed Rudranagar 33/11 K.V. sub-station. Works are in various stages oftendering/construction.237. The present component of work under SPR has been proposed so as to reach gridelectricity to the existing and new consumers for 24 hours from the Rudranagar 33/11 K.V.sub-station that is expected to start shortly.238. The work elements will include erection of 488.51 km of 11 K.V. line, 443.00 km ofL & MV line and distribution sub-station (11/0.433 K.V.) – 356 numbers of 25 K.V.A. and265 numbers of 10 K.V.A.Summary statistics related to the proposed project are tabulated below:ExpectedConsumers31000 Schools 12 (i) Project cost inRupees in lakhs(ii) Project cost tobe financed inRupees in lakhsDomestic 22906 Panchayet 9 Scheme(other thanSamiti officeimplementationBPL)PeriodDomestic 6094 Hospital/ health 3 Implementing(BPL)centreAuthorityCommercial 1024 Police/outposts 43470.263424.502 yearsWBSEDCL
