Overview
• Solid waste is defined as any garbage, refuse, sludge from waste treatment plant,
water supply treatment plant or air pollution control facility and other materials,
including solid, liquid, semisolid, contained gaseous resulting from industrials,
commercials, domestic, mining and agricultural operations from community
activities.
What is Solid Waste?
Waste Generated
House Hold waste
Commercial Waste
Institutional Waste
Dead Animals Waste
Bio-medical Waste
Road Sweeping

Demolition Waste
Type of Waste Generated
Impact of Solid Waste
• Waste breaks down in landfills to form methane, a potent greenhouse gas.
• Leaching: A process by which solid waste enter soil and ground water and
contaminating them.
• Plastic found in oceans ingested by birds.
• Resulted in high algal population in rivers and sea.
• Degrades water and soil quality.
• Chemical poisoning.
• Uncollected waste can obstruct the storm water runoff resulting in flood.
Why Solid Waste Management?
• Population growth
• Increase in industrials manufacturing
• Urbanization
• Modernization
• Modernization, technological advancement and increase in global population
created rising in demand for food and other essentials. This has resulted to rise in
the amount of waste being generated daily by each household.

Himatnagar
Contd…
• Himmatnagar population is 81,137 as per 2011 census data.
• Waste collected per day is 28 metric ton.
• Basically Himmatnagar is depended on door-to-door service.
• 80% of waste collected is from DTD & 20% is unattended.
• 182 Sweepers, Drivers and other staff have been appointed.
• Waste are dumped at Vermin-composite site at katwad road.

Data Used for
Landfill Site
Methodology
Step1: Collection of data about the Himatnagar.
Step2: Study the existing system of SWM.
Step3: To compile the data of the Himatnagar and create
spatial and attribute data of it.
Step4:Deriving Optimum Route and new Landfill Site
Methodology of Optimum Route Planning
digitizing of the roads from the
base map of Arc GIS software.
network dataset of the road network is
derived.
consider whole area or ward is
covered
Plan the optimum route
using the network analyst
toolset

Starting point: Nagarpalika
Ending Point: Nagarpalika
Optimum Km: 14 km
Total Time: 1 Hr
Starting point: Nagarpalika
Ending Point: Nagarpalika
Optimum Km: 12 km
Total Time: 1 Hr
Why do we need Route Planning ??
• From above 2 maps, we have seen that without any stops a vehicle takes minimum
time.
• If the vehicle is stopped for 15 minutes per stop to collect the garbage, the time will
exceed but it will be less than the time consumed now for collection.
• We don’t give you a perfect route to collect the garbage, but we give you the idea of
how to get a shortest route and thus consuming less time and fuel.
Methodology for New Landfill Site
• Data Collected
• Buffer Area for the required data
• Conversion of vector data to raster data
• Reclassify the ground water interpolation data
• Weighted overlay of all the above data
• Condition for the optimum landfill site

Information
Result
• Location of New Proposed
Landfill site
Conclusion
• Solid Waste Management is a major crisis, India is facing right now.
• In the given case study the effort has been made to plan the transportation of waste
with route planning so that it consumes less time covering all the areas.
• A landfill site age is of 20-25 years, existing landfill site near katwad road is
currently in use for recent years. As Himatnagar is growing fast, in future decade
there is a heavy chance of increase in waste generation.
• So, we are proposing a new landfill site around himatnagar so that Municipality is
prepared for future solid waste management.
