Project and Construction Management Services for the Sand Island WWTP Solids Handling project, which consists of 3 separate projects:

1) Primary Sludge Stabilization Facility – The propose of this facility is to reduce the overloading of the existing ESD and serve as a backup system.  The project consists of piping installation along with relocation of existing associated equipment.

2) Solids Return Flow Lift Station – This facility is necessary to convey residual flows from washdown, condenser, scrubber, centrifuge and existing digester.  The project consists of wet wells, submersible pump and approximately 400 lineal feet of gravity lines.

3)  Egg Shaped Digester (ESD) and Sludge Storage Tank (SST).  The project consists of the construction of a second ESD / SST for future plant expansion and maintenance of the existing facility.
