Walden evaluated the condition of this tertiary wastewater treatment plant which discharged treated wastewater to groundwater and featured denitrification filters. The plant was in poor condition but continued to meet its State Pollutant Discharge Elimination System (SPDES) effluent permit limits. Walden prepared a detailed report along with a prioritized list of upgrade/replacement recommendations. This list was coupled with a detailed cost estimate outlining priority “A”, “B” and “C” recommendations, which were compared to available SCCC capital for the work. The list was pared down to cover only necessary work (“A” items). Walden prepared plans and specifications and an accompanying bidding document with “B” and “C” items listed as alternates to the main bid list. Walden received contractor bids and prepared a bid recommendation to SCCC. Walden provided shop drawing review, construction coordination and field inspection of this upgrade project.
