Introduction :
This is the introductory brief of activities
to be performed for landfill.
Also this is a review of landfill
development process to ensure a landfill is
constructed, operated and maintained in
environmental friendly manner.
Land fill
Present Status :
It narrates the present generation
of solid waste, collection system,
Site Characteristics :
 It is the description of proposed
land, its area, topography, access
temperature, humidity, ground
water status, surface water and
drainage system, soil properties etc.
Landfill Design Facilities
The essential basic steps for
landfill design are
Landfill sizing
Site layout
Landfill layout
Leachate management
Landfill gas management
Landfill construction
1st layer – 50 cm thick compacted soil
2nd layer – Geo-synthetic clay liner
3rd layer – 1.5 mm HDPE Geo-membrane
Landfill construction
4th Layer – 30 cm thick gravel. The
gravels should be smooth, and
round of 12 – 15 mm in size.
Leachate collection system of
perforated HDPE leachate collection
pipe embedded in this gravel layer
Landfill construction
5th layer – Geo-textile for filtration.
6th layer – Finally a 300 mm thick soil on
the Geo-textile as a protective layer
Leachate will go to leachate treatment
plant for reduction of BOD, COD and
suspended solids.
Daily waste is leveled, compacted and
covered with fresh earth to give a pleasing
appearance and also to prevent odours.
Landfill Closure
Waste will have to be graded to the necessary
stable slopes.
 1st layer - 200 mm thick gravel to release gas
through gas vents.
2nd layer - 600 mm soil.
3rd layer - 1 mm thick HDPE liner to control
water leaching into soil layer.
4th layer - 150 mm thick gravel for drainage.
5th layer - Geo-textile to keep the soil layer
6th layer - 450 mm thick soil for vegetation.
Monitoring Requirement
Ground water quality monitoring within 50 mtr.
periphery of landfill site shall be periodically
Ambient air quality monitoring will have to
carried 4 (four) times in a year around the site.
Portable methane detection units are available
for the purpose.
The air quality must be monitored for 15
(fifteen) years after the closure of the landfill.
Surface water monitoring around the site is also
For all activities to be performed
detailed estimate on the basis of
engineering details will have to be
prepared to determine the project cost.
How To Monitor
The Construction
Works On
Technical Aspect
Construction Monitoring
It is the process to monitor and control the
activities associated with initiating, planning,
executing, and closing a project.
Problems during execution should be
identified in a timely manner for immediate
corrective measures.
Construction must be monitored and
measured regularly to identify deviations
from the plan.
Construction Monitoring
Free site must be ensured before any
work is taken up.
Site of construction is to be identified to
ensure flawless layout of the work.
Mobilization of manpower, materials,
equipments and resources is most
Construction Monitoring
Monitoring is needed to ensure proper
management on following issues :
Construction Monitoring
Cost Management :
It is necessary to perform cost
control process of influencing the
factors that create changes to the
basic cost to ensure that the changes
are beneficial and according to exact
requirement of the work.
Construction Monitoring
Quality Management :
It is necessary that the quality of the
work is properly ensured in terms of
materials and workmanship
Quality Management
Quality of materials will have to be ensured
before work is taken up : Bricks : Bricks shall be sound, hard,
homogenous in texture.
Bricks shall have a minimum crushing strength
of 105 kg/
Bricks should have ringing sound if struck
Brick absorbing more than 20% of its dry weight
after 24 hrs. immersion shall be rejected.
Quality Management
Sand is the fine aggregate, which shall
pass through IS: sieve designation 4.75
mm, leaving a residue not more than
Sand should be collected from local
river beds
 Sand shall not contain more than 8%
of silt. It should be clean, hard and sharp.
Quality Management
Stone aggregate : This shall be broken
from good hard stone boulder and shall
be free from soft, friable, thin, elongated
or laminated pieces.
This shall be roughly cubical in shape
and shall be clear and free from dirt and
any other foreign matter.
Quality Management
Steel :
Presently we use TMT (Thermo
Mechanically Treated) steel of various
BIS Certification Marking should be
checked in each bundle of bars before
Quality Management
Cement : Net weight of each bag of cement
shall be 50 kg.
Cement stored for over 6 (six) months
shows signs of deterioration or contamination
and should be tested before use.
OPC cement and PPC cement are generally
used for construction.
OPC conforms to IS: 269-1989 and PPC
conforms to IS: 1489-1991
Quality Management
Concrete consistency :
The quantity of water to be used for
each mix of 50 kg. cement shall not be
more than 34 ltr. for 1:3:6 mix, 32 ltr. for
1:2:4 mix., 30 ltr. for 1:1:2 mix.
For vibrated concrete the limit specified
may be suitably reduced.
Quality Management
Curing :
Curing of concrete shall be done after 24
hrs. of laying with moist gunny bags, sand
etc. for a minimum period of 7(seven) days.
Concrete should not be disturbed by
further construction during the curing
Risk Management
Four steps to risk management are :
Risk Identification
Risk analysis
Risk management planning and
Risk review
Risk should be reviewed periodically with the
related persons so that it can be faced and
tackled on time
