Sutter Primary Treatment Facility

Screw Pumps draw wastewater up into the grit room for initial filtration

internal grooves in the screw pump grab water and push it up into the facility

the grit chamber provides the first level of filtration to the wastewater by passing it through a grate removing large debris and allowing inorganic solids to settle to the bottom for extraction

The wastewater is then directed to the 200 foot diameter, 2 million gallon clarifier where heavy solids sink and lighter contaminants float. Both are removed via a skimming arm

An empty clarifier.

Twin primary digesters act like giant stomachs to break down solid waste into methane gas and sludge

The polishing digester further breaks down the sludge produced by the primary digesters and deposits the result into drying beds where the sludge turns into fertilizer

Inside the digesters the sludge is kept in a constant state of motion to avoid creating a toxic environment for the micro organisms.

Pumps then transport the treated wastewater about 6 miles through underground pipes to the Jennings Secondary/Tertiary Plant
