Case Study:

Jersey City East Side Pumping Station Wet Well Project

 

Problem

The Jersey City East Side Pumping Station transmits storm flow and wastewater to a major sewerage treatment plant in Passaic Valley, NJ. The wet well water surface is 25 feet (7.6 metres) below ground level and has an area of 2500 sq ft (42 sq m). The water depth in the well is 15 feet (4.5 metres) deep and the accumulated grease, fat, oils and other materials had solidified to form a blanket on the water surface that varied in thickness from 3 to 10 feet in depth (1-3 metres).

Solution

The blanket of solidified waste was mechanically removed at great expense to the local taxpayers. To prevent a build-up reoccurring, as in the past when it accumulated at a rate of up to 2" (50 mm) per week, the wet well was treated using BioClear Solutions' bacterial treatment and after 6 months the accumulation was practically zero (just a thin film layer).
