 incorporates  gas collection, storage and compressor system  leachate collection, storage and treatment facilities.  prevent leachate leakage into ground water

 gas leakage detection p robes.  leachate monitoring well and ground water monitoring well

 Design & operation SLF  Several important factors must be considered:  land area  cover material  cell design and construction  equipment requirement  personnel requirement  finance  drainage

 spread and compaction  water supply  fire prevention facilities  fencing -  gatehouse  operation time  land use after completion of landfill  wheel cleaning  notice board

 Population protection  site location  rainfall  temperature  Soil type  wind  Hydrological properties and water table

 compaction landfill  essential to reduce settlement  take about 2 years  prevent fire  eliminates odour, flies & vermin  for building structure – 10 – 12 years

 ideally compacted fill should have density of 900 – 950 kg/m 3  densities are measure by using backhoe method and auger method.  the values depend on:

 Type of waste  Pretreatment  Composting of waste  Time of landfill  Moisture content  Type of landfill  Stage of compaction

 Leachate  define as liquid that has percolated through solid waste and has extracted Dissolved or suspended material

 average amount of leachate generated is 150L//tonne  contain organic matter, nitrogen (ammoniacal), suspended solid salts & colouring matter.  constration of eluted matters will be highest the first 3 – 8 years.

 quantity of leachate produced depend on factors:  Soil type  Waste composition  Degree of composition  Rainfall  Evaporation  Landfill type and age
