Document Description
The proposed Project will provide replacement of existing polishing ponds with a new activated sludge treatment facility. A new administration and electrical building (Building A) will be constructed adjacent to the treatment facility. A new Building B will contain headworks and sludge dewatering systems. The existing digestion building will be a renovated Building C. Existing septage receiving station, headworks, primary clarifiers, trickling filters, and secondary clarifiers will be demolished as part of the project. The existing Emergency Storage Basin Pond A will be lined and reused in the proposed Project. The new facilities will be constructed in the location of the existing polishing ponds. The land area will be reclaimed by draining and filling the ponds with approximately 90,000 cubic yards of fill material to be generated onsite.
