INTRODUCTION With rapid urbanization and ever increasing
population growth there has been a substantial increase in the generation of solid waste & contamination of air, water and land resources.
The solid wastes from different municipalities, not managed properly, have been creating problems for human health and environment.
Some of the solid wastes have been proved to be extremely toxic and infectious.
The uncontrolled dumping of such wastes have not only brought about increasing number of incidents of health hazard but also causing the surface and ground water contamination and thus posing serious environmental threat to the human being.

Contribution of GIS in SWM
There are several phases in solid waste management, right from the stage where it is generated till it reaches its final destination or at a stage where it is no more a threat to the environment.
It is observed that solid waste management can be bifurcated into mainly two phases.
One is the waste management in the area where it is generated and second is the management of waste at dumping grounds.
![Page 11: applications of rs and gis in solid waste management](https://reader036.fdocuments.us/reader036/viewer/2022081413/546ecfaab4af9fd7268b476a/html5/thumbnails/11.jpg)
GIS could help in dealing with several factors simultaneously which needs to be considered while planning waste management.
“GIS is a system of computer hardware and software, designed to allow users to collect, manage, analyse and retrieve large volume of spatially referenced data and associated attribute data collected from a variety of sources.”
![Page 12: applications of rs and gis in solid waste management](https://reader036.fdocuments.us/reader036/viewer/2022081413/546ecfaab4af9fd7268b476a/html5/thumbnails/12.jpg)
Thus, the purpose of this paper is to demonstrate the use of GIS and remote sensing techniques to identify appropriate areas which are suitable for reasonable, convenient, and administratively transparent waste-disposal siting in Visakhapatnam.

Waste storage
Providing the system of waste storage on the road side the major activity Primary Waste Storage facilities are made available by GVMC along streets and near commercial complexes. In addition, shopkeepers at a few commercial complexes provide bins for public use. GVMC has about 598 dumper placer container for storage of waste

Primary Waste Collection
Primary waste collection is the important essential step of solid waste management activity. Primary collection system is necessary to ensure that the waste stored at source is collected regularly and it is not disposed of on the streets, drains, water bodies, etc.
The collection of solid waste from the door to door households, shops, and establishment is called primary collection. GVMC has provided Pushcarts (6 tubs), Tricycles to collect the solid waste from the households, commercial establishments etc
![Page 22: applications of rs and gis in solid waste management](https://reader036.fdocuments.us/reader036/viewer/2022081413/546ecfaab4af9fd7268b476a/html5/thumbnails/22.jpg)

Secondary collection
collection of solid waste for the second time, i.e. from community collection points, prior to its transport (often as part of a collection round by larger vehicles) to a transfer station, treatment facility or disposal site.
![Page 24: applications of rs and gis in solid waste management](https://reader036.fdocuments.us/reader036/viewer/2022081413/546ecfaab4af9fd7268b476a/html5/thumbnails/24.jpg)

WASTE TRANSPORT
Transportation of waste stored at waste storage depots at regular intervals is essential. The collection and transportation of waste is practiced on all the days of the year including the public holidays. In GVMC, waste stored in open spaces is either loaded manually or with the help of loaders in trucks.
The vehicles involved in the solid waste transportation in Visakhapatnam include dumper placers, tractors, mini vans, tippers (big & small). Dumper placers will carry the bin and unload the waste at the transfer station and will perform on an average of 12 trips per day. Mini tippers transport the waste from the open secondary collection points to transfer stations.

TRANSFER STATION Being Visakhapatnam is the big city and waste generation
is more and the disposal site is far from the city, transfer station is established to transfer the waste from dumper placers and trucks.
The transfer station is located at town road. The collection vehicle like dumper placers, tippers and tractors will pick up the waste from the secondary open collection points and dumper bins and transfer the waste directly in transfer stations.
A ramp facility is also provided to facilitate unloading of vehicles or dumper placer containers, directly into large containers at transfer station.
Waste is weighed at Weigh Bridge at the entrance gate, a record is being maintained for in time, out time, weight of the solid waste disposing in to the transfer station and vehicle number. The big tipper (20 ton capacity) transport the waste to disposal site located at Kapuluppada which is 25kms away from the city.

DISPOSAL OF WASTE
Currently, the city disposes all of their waste at a Kapuluppada disposal site. This site is operating for the last 5 years with 100 acres.
3 JCB and 1 bulldozer are employed at GVMC for solid waste
management, including the operation of the waste disposal site.
The existing waste disposal site is a dumpsite with no leachate collection and treatment system and does not meet the current requirements of the MSW 2000 Rules.
Open burning of waste, indiscriminate disposal, presence of stray animal & rag pickers at the disposal site and leachate migration into the river are common occurrences.

COMPOSTING
Composting: The controlled biological decomposition of organic matter, such as food and yard wastes, into humus, a soil-like material.
Composting is nature's way of recycling organic wastes into new soil
![Page 38: applications of rs and gis in solid waste management](https://reader036.fdocuments.us/reader036/viewer/2022081413/546ecfaab4af9fd7268b476a/html5/thumbnails/38.jpg)
BENEFITS OF COMPOSTING
Keeps organic wastes out of landfills. Provides nutrients to the soil. Increases beneficial soil organisms
(e.g., worms). Suppresses certain plant diseases. Reduces the need for fertilizers and
pesticides. Protects soils from erosion. Assists pollution remediation.

Solid Waste Site Selection Criteria
A number of essential factors are considered in locating landfill sites. Such factors include both physical and social environments.
The essential factors: Topography, Climate, Surface and Ground Water Hydrology, Geology, Cover material (Land Cover), and Land Uses.
Due to data constraints, we used Topography, Surface hydrology, Existing settlements, Sensitive area and Land development (Roads etc.) of the area as guides to site selection.
![Page 51: applications of rs and gis in solid waste management](https://reader036.fdocuments.us/reader036/viewer/2022081413/546ecfaab4af9fd7268b476a/html5/thumbnails/51.jpg)
Landfill criteria Must not be located within 160 meters of a
wetland Must not be located within 160 meters of a
sensitive area. Must not be located within 200 meters of an
existing waste site. Must not be located within 1000 meters of an
existing settlement. Must be located within 300 meters of major road. No landfill should be constructed within critical
habitat area. No landfill should be constructed within 3048
m(10,000 ft) of any airport. Not be located on or within 500 m of sites of
historic importance.

WASTE DISPOSAL- LANDFILL
CELL is used to describe the volume of material placed in a landfill during one operating period, usually one day
LIFT a complete layer of cells over the active area of the landfill
Landfills for Municipal Solid Waste Milled waste Monofills Fills for gas production

Excavated Cell or Trench Method
Suitable to areas where: Adequate depth of cover material is
available at the siteThe water table is not near the
surfaceTypical trench: 60 to 300 m x 5 to 20
m x 1 m; SS: 1.5 to 2:1
