• As explained on the previous slide,
all such nuisance points are marked
in the map.
• Time taken to clean nuisance point
depends upon the quantity of waste
and ranges between 10-20 min.
• We have observed cases where, due
to completion of working hours i.e.
2:00 PM, waste collection from the
remaining nuisance point is planned
to carry out on the following day.

Micro-pockets
demarcation
SWM-Plan A
Plan A

Micro-pockets Demarcation
Criteria followed to demarcate micro- pocket (MP)
• Less than 300 households in a micro pocket. Buildings with
less than 20 flats are considered under 1 door.
• Each micro pocket can be serviced by one major road where
collection can be done using tractor or push cart
• Density of households is taken into account while
demarcating micro-pockets.
• Each Micro pocket will be serviced by 2-3 sanitary workers
depending upon the size of micro pocket, no of HH’s and
Coverage of main roads in the micro pocket which requires
daily sweeping.
• Micro pocket with very less HH’s density (e.g. MP-18) shall be
only serviced using a auto tipper or tractor

Existing wards and New Micro- Pockets
Existing Wards New Micro-pockets

Route Demarcation
Route selection for door
to door waste collector
Plan A

Route Demarcation
Method followed to demarcate route for door to door waste collector in a micro- pocket (MP)
• Preparation of Road dataset (Major road, Minor road, streets) of Devanahalli town in ArcGIS Software.
• Error detection and rectification of roads (for overlapping or dangles in road dataset) with help of Topology extension in
ArcGIS software.
• After observing the average speed (across 7 surveyed sanitary workers) of the solid waste worker carrying pushcart, the
average of seven such workers was considered and based on that we derived the time in seconds for each road length.
• First we identify the existing collection points where pushcarts travelled.
• To optimize the route, we have followed the Travelling Salesman’s Problem (TSP) method. We retain the collection points
as explained above but re-order the stops, based on the time criterion. The re-ordering of the stops and route
optimization is done by the network analyst option within Arc GIS.
• By following this process, we get most optimum route based on the total time taken and number of households covered
during the waste collection from the collection points.

Route Demarcation
Application and results achieved through the TSP method discussed in previous slide
• Shortest distance to cover maximum no. of households (i.e. up to 150 Door) with minimal overlapping of the route.
• Road junctions/ intersections connecting all the roads, covering all the households were selected. Time was calculated
and noted to cover all the households. In first attempt, for example the time taken to cover all the households was 3.5
Hours with a speed of 0.336 meter/ seconds.
• 0.336 meter/ second is the average speed noted across 7 door to door waste collectors in different routes during the field
level push cart route mapping exercise.
• After the first attempt of Route mapping, the new route was run through GIS software using Travelling Sales Man (TSP)
method for determining shortest possible route with minimum time to cover all the HH’s. After successful running
through software, the new time shown for the same route was 1:17 hour which was earlier shown as 3.5 Hours. (Analysis
shown in next slide).

Initial route selection Route after running through TSP

Electric collection vehicle
with IoT system
Plan B

Collection of segregated waste on electric vehicles with IoT system
• Each vehicle caters to the collection of a pocket of 1000 households, with 3 people on-board.
• The installed solar panel makes up for the charge required for operations, however manual charging can be done.
• IoT system allows monitoring of all the workers and the weights of the waste at gate level at the same time.
• No nuisance points; delivery to designated processing facilities.
• Uses existing manpower of 21 for door-to door collection.
• Electric vehicles minimize the fuel consumption as well as pollution.
• Charging costs Rs.900 per month vs Rs.3900 per month
Plan B: Electric vehicles + IoT system
Cover 1000

• 10 MT Composting Facility
o 4-5 workforce
o Plan A & B: receives waste

o Capital Cost: 51.12 Lakhs
• 5MT Material Recovery Facility
o 5 workforce
o Plan A: receives waste
everyday
o Plan B: receives dry
waste once a week
o Capital Cost: 96.12 Lakhs

Resolutions for Enabling Environment
Resolution for change in SWM process:
• Waste to be stored in 3 bin system
• Plan A: Only wet and domestic hazardous waste will be collected on daily basis by Municipality
Domestic dry waste will be collected once in 7 days.
• Plan B: All 3 categories of waste will be collected everyday , into segregated bins.
• Composting of all the organic waste, upgrading the existing composting capacity of the town.
• Municipality has to fix buying rates of dry recyclable material. Based on these rates the dry
waste will be bought from residents.
