Steps to start Designing a Landfill
The overall approach that the promoter and developer of the landfill should take is that of starting your construction project, completed over an extended period, to construct a desired landform using spend and incorporating appropriate environmental protection measures.
This idea combines the following two elements with techniques which are appropriate for a specific site and it is waste inputs:
1. Established civil engineering practices for permanent and temporary construction, based on a predetermined design, with appropriate performance standards for that materials used.
2. Process engineering to accommodate biological, chemical and physical changes that will take place within organic wastes during the active lifetime of the site.
The key components that need considering after which included in all landfill designs are:
- Requirements for environmental protection, in order to minimise injury to environmental surroundings and to human health, according to current legislation and the aims of sustainable development.
- Recognition of the results of the various nature of wastes as well as their degradation processes on landfill gas and leachate generation, and the potential of those to change during the course of design and operation of the site.
- Utilization of a site-specific risk assessment, instead of prescriptive, approach to environmental protection, for each element and at each stage within the project, to be able to determine the general design and operational practices appropriate towards the environmental setting of every individual landfill site.
- A holistic method of landfill design and operation, utilising scientific and engineering skills being an integrated process from initial conception to final capping, including subsequent restoration and aftercare.
- The adoption of methods, standards and operational systems, based on best current practice, which reflect progress in techniques and improving standards.
- The underpinning of actions with a quality approach, to make sure that the necessary quality is achieved in implementation, which landfill standards match rising public expectations.
The requirement for cost-effectiveness in design, construction and operation of landfill sites to ensure that the right level of environmental protection is achievable in an appropriate cost, is obviously also essential, out of the box the necessity to adhere to the neighborhood regulations imposed in respect of planning and emissions reduction and control/monitoring.
The technique of landfilling really is easy. In essence the waste is deposited in layers, called lifts , within the landfill and above the liner system. As waste is deposited, it is compacted by heavy machinery to maximize the quantity of refuse that can be discarded in the landfill. Waste isn't a hi-tech problem it's a low-tech problem.
What's going to make landfills better isn't magic new technology, no new machines either; it is best design, better organization, better education, both in the municipality level and the site level.
Also for a good landfill both the main emissions of landfill gas and leachate should be planned for from the start, and the facilities for installed before they are absolutely needed, to be sure they are ready when really necessary.
Leachate could be pumped towards the collection pond or flow to it by gravity. A leachate collection tank is designed to catch and isolate the contaminants that can get into environmental surroundings. Great landfills attempt contain leachate at the site and prevent its discharge to come to light or groundwaters, but it's simple to leave the provision of leachate treatment past too far, and also the not have access to a facility ready for when heavy rains arrive.
