Savannah Waste Management and Landfills

Savannah Dumpster Rental Services

Dumpster rentals are used by Savannah residents to bring their junk to the landfills. This is good waste management practice, as it helps recycling and sustainabiliy. Junk disposal is part of home and business maintenance, and it can occur after a clean out, a removation or a remodeling.

By landfills need to be managed by the government of Georgia, it is important to isolate the landfill from the natural subsoil, it is necessary to isolate the aerial part of the buried waste mass in a sustainable way.

A distinction must necessarily be made here between waste coverage, at the end of each day of operation, and final coverage after closure. So that the first is made of a simple layer of soil aimed mainly at preventing the scattering of waste by the wind or animals and at limiting odors, the second aims to confine and/or channel harmful elements to ensure their management .

Thus, the final cover serves not only to isolate the waste from the population and the environment, but also as protection against erosion, as an “umbrella” to reduce the infiltration of water that can increase the amount of leachate, of a “cap” allowing the biogas to be channeled and finally of a base layer in order to prepare the rehabilitation of the surface occupied by the landfill.

The realization of the cover will be in more ways similar to the development of the base of the landfill but presenting an inverted succession of the different layers of materials. Thus, above the waste, one will find in order a geotextile, a gas draining layer, a protective separation layer (for example, geotextile or geogrid), an impermeable sealing barrier (HDPE membrane and clay barrier) or semi-permeable (layer of inert materials of given permeability), a biological barrier, a draining layer of atmospheric water and finally a layer of arable land allowing the seeding of grasses and small shrubs.

The total thickness of the cover will reach from 1 to 1.5 m. The permeability characteristics of the waterproofing barrier will be chosen according to the desired level of atmospheric water infiltration in order to maintain or gradually reduce biological activity. Not included among the landfill base features, the biological barrier serves to protect the lower layers against the progression of plant roots, insects and rodents.

To avoid the use of insecticides and for better waste collection, sources of contamination of watercourses and groundwater, a layer of construction debris of 30 to 90 cm will often be used. The laying of the cover must respect a domed profile which, taking into account the phenomena of settlement of the waste, will print slopes of 6% after total stabilization, with locally slopes of 3% authorized.

Particular attention will be paid to the integrity and durability of the membrane and the barrier, which could be called into question in three ways: chemical, environmental and mechanical. Chemical attack is least likely to occur if the materials are properly chosen. It results from reactions between vapors and gases and the constituents of the membrane or barrier.

The environmental challenge is due to drought, humidity and root penetration. The mechanical attack results from overloads, high compaction, incorrect humidity at the time of compaction, drilling by gravelly materials and tensions up to failure linked to differential settlements in the lower layers. Here again, laboratory analyzes will determine the most appropriate materials, soils or mixtures of soils. The gas drainage layer serves to evacuate the gases produced at the level of the waste.

It generally includes a layer of highly permeable granular material (permeability > 10–2 m/s) at least 30 cm thick placed as close as possible to the waste. The most significant settlements occurring in the first 5 years after the end of operation, it is preferable to wait for the end of the major differential settlements before carrying out the final cover.

In the meantime, a cover made of relatively clayey materials must allow a certain migration of gases and favor the runoff of surface water rather than their infiltration into the massif. We should also emphasize the attention to be paid to the sustainability of degassing wellheads.

The top ends of the wells can be placed below or above the landfill cover soil depending on the future use of the space. They are usually placed in a concrete chamber with a movable steel or concrete cover. Again, as the landfill will experience significant settlement, the end of the shaft should be installed taking into account the landfill situation.

For landfill reason and better Georgia junk disposal, it is also recommended to make the junction between well and extraction system by flexible and sliding joints. It is also important to predict changes in the network during settlement to management dumpster rental trucks.
