The effective management of leachate within a site continues to
present a challenge to landfill operators. Every site is different
and demands a unique solution. At Biogas we have gained experience
over a wide range of sites and installations and have developed
effective solutions to the regular problems encountered.
Where the quantity of leachate to be pumped is variable and low,
and perhaps distributed over a large area, then pneumatic cylinder
pumps can offer particular benefits - and still fit within
established gas wells for ease of installation. Similarly where
there is an efficient leachate drainage system within the site
which collects the leachate at one or two deep locations, then
conventional submersible pumps can be effective.
Biogas have experience of a range of pumping methods and so can
determine the most effective approach for individual sites, and
provide a successful installation.
Discharge or Treatment
Output arrangements from the extraction system can be supplied to
suit specific site requirements. Discharge can be pumped or by
gravity, and the system supplied with automatic sampling and
monitoring or linked to treatment plant. In some cases leachate
recirculation may be used to optimise gas production, or spray
irrigation for on-site disposal.
The Wider Perspective
Within many sites the management of leachate is directly linked to
the management of landfill gas, since there is a recognised
interaction between the two. Where a gas utilisation scheme is in
place and leachate levels are high, an effective leachate
extraction system may increase gas yields. And the potential for
re-circulation of the leachate within the landfill mass as part of
a progressive management system may create further opportunities
for an increase in gas production.
It is therefore highly beneficial to approach landfill
environmental management in a coordinated way, considering the
tasks of leachate extraction and treatment along with gas
management and a clear understanding of the other elements of the
landfill management process in the site.
Leachate extraction is an integral part of Biogas Technologys
unrivalled capability in landfill environmental management. We have
earned a reputation for innovation in the application of technology
and for excellence in the quality of service we offer our clients.
Our success is built on providing single-source accountability to
our clients whatever the range of services being supplied - from
fieldwork, through integrated gas and leachate management, to gas
utilisation and power generation schemes. We offer clients
guaranteed solutions to the specific problems and opportunities
presented by each individual site and back this up with a
