SUMMARY:
The Selection Advisory Committee met on August 3, 2012 to consider the following project:
Southside Water Reclamation Plant Solids Dewatering Facility Replacement -
Project No. 4781.60.
PROJECT DESCRIPTION:
A new solids dewatering facility (SDF) is required at the Southside Water Reclamation Plant (SWRP). The SWRP has a nominal capacity of 76 mgd and uses anaerobic digestion to stabilize the sludge. Dewatering is performed using centrifuges. The existing SDF, does not provide reliable service, requires large amounts of annual maintenance, is at the end of its useful life, and needs to be replaced with a new, modern facility. The Engineer will conduct a preliminary design, prepare a Design Analysis Report (DAR), prepare a detailed design including construction bid documents, and provide engineering services during construction. Additional work may be authorized.
FISCAL IMPACT:
Estimated construction cost is $10,000,000 to $15,000,000 per year which includes permitting, design, & construction. Funding will be provided through the Water Authority's Capital Implementation Program. The project study, design, and construction phases should be completed in a three year time frame.
PROJECT JUSTIFICATION:
The existing SDF creates workplace hazards for Water Authority employees, does not provide reliable service, requires large amounts of annual maintenance, is at the end of its useful life, and needs to be replaced with a new, modern facility. The new SDF will provide a safer facility reducing risk of personal injury to Water Authority staff. It will also provide a more reliable facility reducing the risk of National Pollutant Discharge Elimination System (NPDES) permit violations. The new SDF will also have improved odor control systems to reduce the risk of malodorous ...
