Waste Water

Sample Well Basin

A Sample Well is used in sewer applications to allow for periodic sampling of the wastewater (usually required by the Administrative Authority). Wastewater samples are used to monitor the performance of Grease/Lint interceptors, Oil/Water Separators or Acid Neutralization Tanks. Samples are taken from the sample port or by removing the cover. The sample is then sent to a laboratory for analysis for BOD, TSS, pH, and Oil/Grease content.

For periodic wastewater sampling of:
