Presentation transcript:

Scientific or Engineered Landfilling of Waste Minimizing waste reaching landfills. Place the waste in new landfills in a manner that it does not harm the nearby environment. Adopt rehabilitation measures at old waste dumps to minimize or eliminate their harmful impact on environment.

IMPACT ON ENVIRONMENT Source: (a) Solids in the waste, (b) liquids in the pore space of waste, (c) gases in the pore space of waste Pathways: precipitation, infiltration, seepage, (b) surface run off, (c) ground water flow, (d) wind, (e) drains and streams, (f) rodents and pests, (g) vegetative growth on waste Receptors: (a) Adjoining areas, (b) people, (c) animals, (d) vegetation, (e) built and protected habitat

COMPONENTS OF ENGINEERED LANDFILL A Liner System at the base and sides of the landfill which prevents migration of leachate or gas to the surrounding soil. A Leachate Collection Facility which collects and extracts leachate from within and from the base of the landfill and then treats the leachate. A Gas Control Facility which collects and extracts gas from within and from the top of the landfill and then treats it or uses it for energy recovery. A Final Cover System which prevents migration of gas to the atmosphere, enhances surface drainage, interprets infiltrating water and supports surface vegetation.

COMPONENTS OF ENGINEERED LANDFILL A Surface Water Drainage System which collects and removes all surface runoff from the landfill site. An Environmental Monitoring System which periodically collects and analyses leachate, air, surface water, soil-gas and groundwater samples around the landfill site. A Closure and Post Closure Plan which lists the steps that must be taken to close and secure a landfill site once the filling operation has been completed and the activities for long term monitoring and maintenance of the completed landfill (typically 30 to 50 years)
