Department <strong>of</strong> Corrections<br />

Sewage Grinder/Sewage Outflow Meter<br />

The <strong>Washington</strong> Corrections Center <strong>for</strong> Women (WCCW) received numerous<br />

complaints from <strong>the</strong> City <strong>of</strong> Gig Harbor regarding <strong>the</strong> high number <strong>of</strong> bulk items <strong>the</strong>ir<br />

sewage treatment plant was receiving from our facility. Types <strong>of</strong> bulk items included<br />

plastic bags, clothing items, etc., which <strong>of</strong>fenders would flush down <strong>the</strong> toilets. This<br />

caused equipment malfunctions <strong>for</strong> <strong>the</strong> City. In addition, since WCCW did not have a<br />

sewage outflow meter, <strong>the</strong> City was basing sewer charges on <strong>the</strong> amount <strong>of</strong> incoming<br />

water <strong>the</strong> facility received. Since not all incoming water eventually exits via <strong>the</strong><br />

sewage system, we were being overcharged.<br />

As a result, WCCW installed a sewage grinder to grind all effluent be<strong>for</strong>e it reached<br />

<strong>the</strong> City sewage treatment plant. WCCW also installed a sewage outflow meter to<br />

accurately account <strong>for</strong> <strong>the</strong> volume <strong>of</strong> sewage being sent to <strong>the</strong> City <strong>for</strong> treatment.<br />

<strong>Results</strong><br />

! Reduced <strong>the</strong> complaints from <strong>the</strong> City regarding bulk items in our effluent, which<br />

caused <strong>the</strong>m mechanical problems, by installation <strong>of</strong> a sewage grinder.<br />

! Reduced WCCW’s sewer charges by approximately $4,000 per month due to<br />

installation <strong>of</strong> <strong>the</strong> sewage outflow meter.<br />
