181environmental pollution goes unabated. A pilot scheme was initiated sometime back to takecare of bio-degradable wastes, applying process of vermicomposting. The said scheme atpresent is lying non-functional. Sankarpur is comparatively a new area emerging as atourists‟ destination. Sankarpur suffers from total absence of any solid waste management tohandle the daily refuge generated by tourists as well as by the local residents. As a result, thebeach area is getting continuously polluted. In order to address the problem confronted bothat Digha and Sankarpur, a solid waste management system has been planned to becommissioned for both the areas. The system of solid waste management for both the townswill be created in the same manner.208. The proposed management system consists of primary sorting of the solid waste atthe points of generation, collection and transportation of sorted refuge, putting thebiodegradable materials into process of vermicomposting, recycling of the nonbiodegradable but reusable refuge components and finally disposal of non biodegradableremnants through engineered sanitary land filling system. Towards sanitary land filling, onesuitable site common to both Digha and Sankarpur has been identified. The proposed site forsolid waste disposal at Padima mouza of Digha lies beyond the Coastal Regulation Zonewithin land ward side. Therefore, no CRZ compliance is necessary.209. The primary segregation of waste at sources will be undertaken in dwelling houses,hotels and commercial establishment in three categories namely, organic waste, inorganicnon recyclable waste and inorganic recyclable wastes by depositing each category of wastein different colour identified containers. Similarly, waste generated in community use will becollected in separate bins meant for organic waste and inorganic waste. The street waste willalso be collected in community bins .The segregated wastes will be collected and transportedin containers by pedal tricycles to primary transfer stations (PTS) to be located in nine placesfor which the Digha town will be divided into nine segments. The wastes from the containersof each tricycle will be transferred to bigger containers at PTS whence the wastes will betransported by prime movers to the disposal ground. The solid wastes on reaching thedisposal ground will be finally treated for safe disposal in the following three processes :i) Compostingii) Secured Land Fillingiii) Recycling210. The organic solid will be put to composting by two different process viz.vermicomposting (50% of organic waste) and windrow composting (50% of organic waste)under one composting shed. The recyclable non-organic will be disposed of through agency

182to be selected. The inorganic non-recyclable waste will be treated by engineered securedland filling.211. The container for storage of solid waste will be made of plastic with lid and handle.The pedal tricycle will have a capacity to accommodate 6 nos of 50 litres containers that willalso be made of plastic with lid and handle. The community bin may be constructed ofmasonary with tile finish outside having a size of 1200 mm x 900 mm x 800 mm with 2 flapdoors and two flap shutters. Litter bins (50 nos) will be made of fibre glass attached toconcrete posts. The PTS will be of masonary construction with provision of ramps formovement of pedal tricycles. It will have unloading quay.212. The vermiculture unit will require spraying of water regularly. It will be kept undershed for protection from sunlight. Initial decomposed organic waste will be placed oververmiculture unit. The windrow composting will have marked bay where the day‟s organicwaste will be placed in rows. Water will be sprayed to have 50% moisture. On every sixthday the waste row will be tilted upside down for proper mixing. The organic waste will beconverted to compost in 21 days. 15 days maturation period is required before use. Securedlandfilling will be engineered operation with earth cover and compaction. The landfill willhave a final cover of 30 mm earth and landscaped top.213. The design of solid waste management system for the town Digha has been donewith the following considerations:- Primary Storage, Primary Collection and TransportationDesign Year : Present - 2009; Future - 2016 Secondary TransportationDesign Year : Present - 2009; Future - 2016 Treatment and DisposalDesign Year : 2039 (30 years design period)The current (2009) generation of solid in Digha is given below Weekends (non-seasonal) – 11.44 MT Weekends (seasonal) - 14.04 MT Weekends/holidays (seasonal-peak) – 15.67 MTThere is an increase of 2% per year.214. The total container requirement (2009) has been estimated as follows:Residential housesNumber of Green Bin (organic waste) of 5 litres capacity: 3718Number of Black Bin (inorganic non-recyclables) of 5 litres capacity: 3718;
