SPA2IS Controls and Monitors Wet Wells

Wastewater Treatment Application

SPA2IS Controls and Monitors Wet Wells
Municipalities often have several wet well locations around a city that pump waste from low lying areas up to main sewage veins that feed waste treatment plants.  Level instruments monitor the wet well level and controllers then engage the grinder pumps.  Since wet wells contain waste, volatile gasses such as methane require that these level instruments be rated for use in Class I, Div 1 environments.
