1Development of Sanitary Landfill and Capping of Existing Dump site at Mysore.
2Project conceptMysore being mission city of JnNURM, GoK opted development of MSW project on PPP (BOT) model.JnNURM grant of Rs.11 Crores has been sanctioned by CSMC of JnNURM, MoUD, GoI.Through open bidding JUSCO Ltd. has been selected as BOT operators.Agreement between JUSCO & MCC was signed on 1st July, 2010.
3DESCRIPTION OF THE PROJECT Name of the Project:Build, Operate ,Maintain & Transfer of MSW Disposal facility for Mysore City Corporation, Mysore.Scope of Work:Establish an Engineered Landfill facility, capping of existing garbage dump & Development of Infrastructure facilities.Operation & Maintenance:13.8 years every day operation & Closer of Sanitary Landfill (SLF).Maintenance of post closure SLF up to 10 years .
4CAPPING OF EXISTING GARBAGE The entire existing garbage is organized in to two various locations.Closer No:1 (Seven acre)- where the large quantity of garbage is dumped since many years.Closer No:2 (Five acre)- to develop new capping area.
5SALIENT FEATURES OF CAPPING Closer No:2 (Five acre):Provide HDPE bottom linerOrganise garbage in trapezoidal shape with side slope of 1V:3H.Provide impervious layer of 600mm thick ( permeability 1X cm/sec)Provide 450 mm thick top vegetative soilProvide Gas vent system using HDPE pipes and filter mediaLeachate collection systemCloser No:1 (Seven acre):Organise garbage in trapezoidal shape with side slope of 1V:3H.Providing top impervious layer of 600mm thick ( permeability 1X cm/sec)Provide 450 mm thick top vegetative soilProvide Gas vent system using HDPE pipes and filter mediaLeachate collection system
6Components of Landfill Impervious bottom linersLeachate Collection and Removal SystemLeachate Treatment PlantStorm Water DrainageGas vent and flaring system
7DEVELOPMENT OF LANDFILL Steps of developing SLFExcavation of land with slope of 1V:3HProviding multiple bottom liner of GCL, HDPE, Drainage media & Leachate collection network.Construction of Leachate Treatment Plant.Capping, Gas vent System & Vegetation.Post maintenance.

10SALIENT FEATURES OF THE LTP Sl. No.Particulars of treatment unitsDimension in Mts.Compliance and remarks1.Leachate collection tankThe design is carried out considering the total leachate collected from SLF and both the capping areas ( cum per day ).2.Anaerobic reactor i.e. UASB with gas vent system connected to flare stack.4.0x2.7x2.53.Aeration tank with surface aerator 5 HP.5.0x3.0x2.74.Settling tank with hopper bottom.3.0x2.85.Sludge drying beds – 2 Nos.2.0x2.0x2.5
12ENVIRONMENTAL MONITORING SYSTEM Ambient air and Ground water quality before and after operation will be monitored regularly.Monitoring bore wellsBuffer zone around the project area will be developed with necessary plantations.Rain water harvesting will be implemented.Laboratory facilities.Environmental Engineer will monitor the SLF activities.
13PRESENT STATUS OF PROJECT Old garbage of about 4.50 lakhs cum has been reorganized in 7 & 5 acre capping area. Providing clay and vegetative liners above compacted waste is completed.Excavation of landfill for 1st phase in 9.2 acres is completed.Laying of GCL,HDPE, Drainage layers and Geo-textile& soil for first cell completed.Development of infrastructural facilities are completed.
14The 1st cell sanitary landfill site is constructed in an area of 2 The 1st cell sanitary landfill site is constructed in an area of 2.5 acres by digging a pit of size 80X110X3.5 mts.The filling of compost rejects for the first cell sanitary land fill site will enable to fill 45,000 MT of compost rejects at the rate of 90 TPD and they proposed to fill and complete the first cell in 1 1/2 years time.The closure plan of sanitary land fill site includes the covering of the cell by clay and soil media above which vegetative cover with gas vent and storm water collection system.Overall this firm can handle 1,35,000 MT of compost rejects in phase manner.
