Let’s not kid ourselves – landfill leachate is some nasty stuff. If it has gone into the landfill, there is the likelihood that it has concentrated in the landfill. This environment can make it exceedingly challenging for primary devices (flumes, weirs, and other meters) to…

Fiberglass Manholes are lightweight (~1/10th the weight of concrete), corrosion resistant, and watertight. Their installation is straight forward and can be accomplished with less manpower and equipment than a traditional concrete vault or manhole. Where line downtime is a…

One of the primary advantaged of fiberglass flow metering manholes is the ability to accommodate flumes much larger than will fit inside the manhole. By being able to laminate the flume to the manhole barrel, flumes can readily extend upstream / downstream of the manhole barrel…

A Packaged Metering Manhole (PMM) is a fiberglass manhole into which a primary device has been integrated. In addition to the above, Packaged Metering Manholes allow the integration of primary devices larger than would otherwise be able to be easily accommodated in concrete…

Metering manholes are a convenient way to measure flows in a wide range of applications, including: wastewater treatment plant headworks / influent, treated effluent, in-plant flows, industrial discharge, or monitoring the flow of sewage in a collection system. Capable of…

Reduced to its most basic elements, a flow Metering Manhole is a fiberglass (FRP) manhole with a factory integrated flow element to measure the flow of water in a pipe. Most Metering Manholes integrate flumes (typically Parshalls), although weirs and magnetic flow meters can also…
