LANDFILL DESIGN (SITING CONSIDERATION)
:european_post_office:
FACTOR
:red_flag:
Available land area
Useful life > 1 year (min value)
Haul distance
Will have significant impact on operating costs
Soil conditions and topography
Cover material must be available at or near the site
Surface water hydrology
Impact drainage requirement
Geologic and hydrology conditions
Local environment conditions
Noise, odor, dust, vector, aesthetic factors control requirements
Ultimate use of site
Affects long-term management for site
Climatologic Conditions
Provisions for wet-weather operation
SITE SELECTION :star:
Phase 1: Site rating process (negative mapping)
Phase 2: Identification of site areas (positive area)
Phase 3: Site investigation
Phase : Final decision
PHASE 1
Exclusive criteria are
Drinking water protections ares
High flood areas
Unstable ground
Extreme morphology
Unsuitable geological and hydro logical conditions
Residential area including protection distance
Nature protection area
Important cultural sites
PHASE 2
Criteria for elimination process by ranking
General data such as volume, distance from main waste source
Hydro-geology and water management
Geo technical and constructional aspects
Meteorological aspects
Nature protection and land use
SITE CONSTRUCTION REQUIREMENT
: :check:
Operations
Confined to a small an area as possible
Compacted to reduce their volume
Covered (usually daily) with layers of soil
Costs
Feasibility studies
Site after care
Site investigation (cost involved make small sites)
Capacity of the waste
Density of waste
Amount of daily cover
Amount of settlement (density of compacted waste)
Construction of lining and drainage
Layers
Stability
Underlying geology
Nearby earthquake faults
Water table
Location of nearby rivers , stream and flood plains
Location
Easy access to transport by road
Transfer stations if rail network is preffered
Land value
Cost of meeting government requirements
Location of community served
Protection of soil and water
Installation of liner and collection systems
Storm water control
Leachate management
Landfill gas management
