Sanitary Landfill (SLF) is designed on the principle of waste control and is characterized by the presence of a liner and a leachate collection system to prevent groundwater contamination and a capping system to prevent air contamination. This paper aims to design a SLF for an enduring and sustainable Solid Waste Management (SWM) system in Jeetpur Simara Sub-Metropolitan City (JSSMC), assisting researchers and designers working in the field of waste management with an easy methodology of SLF design and encouraging municipalities for SLF practice. An area type SLF of dimension 80 m x 80 m with a mineral linear system and a capping system can accommodate Municipal Solid Waste (MSW) of this city for 15 years in an environmentally sound modus producing an achievable amount of 3,434 x 106 m3 of Landfill Gas (LFG) over the lifetime of the SLF. The total heat content value of this achievable LFG over the lifetime of the landfill is about 6.40 x 1013 KJ.
