Shillong, Oct 2: The Phase 1 of the Sanitary Landfill for disposal of processed rejects and inert waste at Marten, Mawlai was dedicated to the State on Monday by Meghalaya Urban Affairs Minister RV Lyngdoh. The project has been funded by the Union Ministry of Housing and Urban Affairs and Asian Development Bank.

Dedicating the landfill site to the citizens of the city, Lyngdoh said the landfill site will go a long way in keeping the State Capital clean by ensuring that the waste generated are properly segregated and dumped at the site. He also said that the government is embarking upon other technological-based solutions on waste magement to make Meghalaya a garbage-free State.

The sanitary landfill site will be developed in an area of 15,000 sq metres and is part of the 18 acres diverted by the Forest Department to the Shillong Municipal Board (SMB) for use of waste disposal and magement. In the first phase, 6,500 sq metre of the area available has been developed for the purpose under Tranche 1 of NERCCDIP at a cost of Rs 7.57 crore and the work was completed in May this year. The landfill has a design life of three years and nine months.

The sanitary landfill in the balance area (8,500 sq metre), including ancillary works, is being carried out at a contract cost of Rs 19.33 crore. The work started in April 2016 and the construction period for this phase will be 24 months. The work has been taken up under Tranche 2 of the programme.

Both phases of the sanitary landfill will cater to the requirement of about 10 years in proper disposal of the inert waste (waste which cannot be processed or recycled) and rejects from the processing facilities.

The sanitary landfill was designed for disposal of only the rejects from the processing plants and the inert waste. The work involves construction of retaining walls to support the cells, laying of geo membrane over geo synthetic clay liners which will prevent seepage of leachate from the waste into the ground. The leachate will instead be collected by leachate pipes laid at the bottom of the cells and taken to a treatment tank to avoid contamition of ground water. The cells will be filled up by the rejects coming from the compost plant or any other treatment units and will be rolled and covered with soil or other inert at appropriate intervals. On fil closing of these cells, the entire landfill will be covered with vegetation and can be used for other purposes.

During the programme, the Minister distributed prizes and certificates to the winners of Shillong Hackathon 2017 and also handed over the certificates to two localities – Upper Lansolane and Cleve Colony – for best practices in waste magement and maintence of cleanliness.
