Sludge Management Plan for Catholic Conference
Center WWTP
The Catholic Conference Center wastewater treatment plant is a WW-2 facility that serves the
guests and staff of the conference center. Due to its small size, sludge and solids removal
happens on an as -needed basis. This typically occurs once annually. When solids accumulate in
the secondary clarifier, they are pumped by a local septic tank company, typically Lake Norman
Sewer and Septic Services in Denver NC and disposed of accordingly.
