QED has a suite of online tools that are designed to help you make the right decisions about landfill gas flow, orifice plate selection, and AutoPump® (Patent Pending) air consumption. Here, we will be highlighting QED’s Landfill Gas Dewatering Calculator.

Reducing liquid levels in landfill gas wells is one of the most important factors in collecting landfill gas. Excessive liquid levels can hinder the free flow of gas into the screened section of the well. Installing a pumping system in the well exposes more of the screen section, which can increase collection rates.

The Landfill Gas Dewatering Calculator from QED lets you easily estimate the additional gas flow and revenue that can be generated by dewatering landfill gas wells. Input your values for additional gas flow per foot of exposed screen in standard cubic feet per minute (SCFM), the percentage of methane in your landfill gas, and the current market value of methane in your area. You will be able to see the financial increase as a direct result of reducing liquid levels in your gas wells. In many cases, the increased gas flow produced by exposing even a few more feet of screen can pay for the pumping system in less than one year, and provide higher revenues for many years thereafter. The additional gas collected will also enhance methane capture and reduce potential fugitive emissions. To get an overall site perspective, enter the number of wells on your site for a quick estimate of the total additional revenue that you can generate.
