WPCA Inspection and Maintenance
There is a rigorous schedule of inspection of the entire sewer works nearly every day. Each of the pump stations are visited daily. This is a standard practice among WPCA enterprises in across Connecticut. This is done to be sure there is not a problem that may cause an environmental, health or safety problem.
In addition, each property with a commercial kitchen connected to the sewer system, must be equipped with a 1000 gallon tank to serve as a trap for FOG - Fat, Oil and Grease. This is a standard technique to prevent grease from fouling or even blocking the sewer lines. The grease is trapped at the top of the water level and pumped out according to an established schedule. There is a regular inspection of these traps, mostly associated with resturants.
What is the worst that can happen? Here is a story from May, 2009:
Krispy Kreme Clogs More than Arteries
Oops! Did Krispy Kreme doughnuts clog the sewer? Those delicious warm glazed beauties are being blamed for clogging more than just arteries, and Associated Press report details. A Virginia county is like many others and is looking for cash anywhere it can get it and while waiting on those big stimulus bucks they have turned to the courts.
Oops! Krispy Kreme Sewer Dump - Lawsuit
AP reports: "Fairfax County says the company has damaged its sewer system by dumping yeast and grease from a plant in Lorton. Officials filed a lawsuit this month after the company refused to pay a $1.9 million bill for repairs to the system."
The Washington Examiner adds that the lawsuit says the damage was caused by "excessive quantities of highly corrosive wastes, doughnut grease and other pollutants."
It gets worse, according to the lawsuit that was filed the "clogged pipes resulted in raw sewage leaks that shut down the southern Fairfax sewer system." The county officials say its workers once ran a closed-circuit camera inside a pipe to show the grease deposits, but the camera got stuck in the goop.
N.B. Krispy Kreme disputes the claim and blames the sewer clogging on poor maintenance.
