What is the difference between water treatment and wastewater treatment?
Water treatment is done to water before it is sent to a community, while wastewater treatment is done to water that has been used by the community. Water treatment has higher standards for pollution control because it is assumed that any drop of distributed water could be consumed by a person.

What is a snail settling basin?
As part of a larger plant rehabilitation project, PECI designed a special settling basin to capture snails from a trickling filter process. A pumping system was designed to move the snail-laden slurry into a classifier so that snails could be deposited in a roll-off container for hauling off-site. The project significantly reduced snail accumulation in downstream basins.
What is Perkins Engineering Consultants?
is serving as the prime consultant to retrofit existing traveling bridge sand filters with cloth filters for a 24 MGD wastewater treatment plant. The project consists of modifying the filter basins to accommodate the proposed filters, installing new influent weir gates, drain and yard piping modifications, and a structural canopy to cover the filter basins. The project site is subject to potential flooding, so additional design elements such as shut off switches, equipment enclosures, and raised control panels were implemented to protect the equipment should flooding events occur. This project is currently under construction and expected to be finished in first quarter 2022.
