Interceptors require a retention time of 30 minutes to allow the fats, oils, grease, and food solids to settle in the tank. As more wastewater enters the tank, the grease-free water is pushed out of the tank. The rotting brown grease inside a grease trap or grease interceptor must be pumped out on a scheduled basis.
The amendment was supported by the U.S. and Ohio EPA, the release continued. ... The EPA proposes the plant be built to handle overflows that might occur from the Ohio Canal Interceptor Tunnel ...
Combined sewer outflow into the Anacostia River in Washington, D.C. Ratcliff Beach CSO discharges into the River Thames in London [7]. These relief structures, called "storm-water regulators" (in American English - or "combined sewer overflows" in British English) are constructed in combined sewer systems to divert flows in excess of the peak design flow of the sewage treatment plant.

When atmospheric carbon dioxide (CO 2), or carbonate ions (HCO − 3, CO 2− 3 dissolved in water) diffuse into concrete from its external surface, they react with calcium hydroxide (portlandite, Ca(OH) 2) and the pH of the concrete pore water progressively decreases from 13.5 – 12.5 to 8.5 (pH of water in equilibrium with calcite).
A Buchan trap (alternative names: Bristol interceptor, [1] interceptor trap and disconnecting trap) is a device fitted in a domestic sewer pipe to prevent odours entering the pipe from the public sewer [2] and permeating the house, a common problem before individual plumbing fittings were separately trapped.

Lamella clarifiers can handle a maximum feed water concentration of 10000 mg/L of grease and 3000 mg/L of solids. Expected separation efficiencies for a typical unit are: 90-99% removal of free oils and greases under standard operation conditions. 20-40% removal of emulsified oils and greases with no chemical amendment.
