New white paper on leachate pump selection and operation from Geotechnical Instruments

This new white paper provides guidance and information on the selection and operation of positive air displacement pumps for landfill leachate and condensate pumping.

This vitally important pumping is maintained in landfill environments; corrosive and hostile for any pump. The white paper based on the UK's 17 years' experience and development considers pumps and their borehole environments from the sump to the top, connected airlines and piped removal of pumped liquid.

Leachate pumping success mainly depends on two factors; customisation and regular inspection and maintenance. Widely adopted air displacement pumps, since the 90s, have proved their capability and shown they are appropriate for these tasks.

However, in identical environments, the more appropriately pumps are made, the longer they last - giving best value after just a few years. Pump customisation may include selecting site-appropriate materials for interchangeable components. Each component is relied on even more if maintenance checks are missed or inspection intervals lengthen.

That is attractive to those operators who only inspect and carry out maintenance if there is a problem. The white paper provides a guide for landfill site operators to assist them achieve the best pumping performance to achieve desired results, compliance and value for money.
