Background• Earlier area of 105.6 sq.km., expanded to 257 sq.km. by 2012, and the second

largest city of Tamil Nadu, surrounded by Western Ghats on the west and Noyyal River in the South,

• Tropical wet and dry climate, with maximum temperature as 35.8 Deg.C. and minimum as 22.4 Deg. C. and annual average rainfall of 71 cm.

• Population in 2001- 9.31 lakhs Population in 2006- 10.09 lakhsPopulation after expansion-15 lakhsFloating population-15%

• Waste Generated- 815 TPD• It further estimated that the calorific value of the garbage is 2381 Kcal/kg.• Tamil Nadu is one among the most urbanized states in India with 43.86% of

state population living in urban areas.

Waste Generation• Waste produced

1999-2000 = 350 TPD 2004-05 = 530 TPD 2010-11 = 700 TPD• Per Capita waste generation- 550 gms• Coverage door to door waste collection- 80%• Composition of MSW determined on a wet weight basis and it consists mainly of

large organic fraction (40-60%)ash and fine earth (30-40%)paper (3-6%)plastic, glass and metal (each <1%)

• The C/N ratio ranges between 20 and 30• The lower calorific value ranges between 800-1000 kCal/kg

Current scenario• Available land for waste disposal – 654.54 acres• Total number of sanitary workers• Permanent- 6354• Contract- 965

Compliance of MSW rules, 2003• Prohibited littering of waste in the streets and storage of wastes at source in 2

bins• 55.3% households and 20.83% shops started storing the waste at source• Segregation of recyclable waste is 9.09%• Organised primary collection from door step is introduced in 43.96%• Secondary storages: 84% of city storage are on site open storage.

Current scenario• Organized transportation: System uses two large MT containers without

proper synchronization with primary collection system.• Waste processing: No proper facility except a 50MT vermi-compost plant,

which processes 20MT per day at the Vellalore site. The entire waste of the city is disposed at the landfill site, untreated.

Methodology • The applied methods for

the implementation of the SWM. Dustbins Door to Door collection Door to Door collection

to common placeTransportation to treatment plants

Segregation and treatment

Incineration Recycling

Methodology• Use of GIS-• A Geographic Information System (GIS) is a computer tool for capturing

storing,querying, analyzing and displaying spatial data from the real world for particular set purposes.

• This technique is used to generate optimal route for collecting solid waste. GIS is a tool that not only reduces time and cost of the site selection, but also proved a digital data bank for future monitoring program of the site.

• Therefore, objective of the present study areto estimate the ward wise per capita solid waste generation and to prepare a distributionmap of waste generation in the urban limit of Coimbatore.
