Estimated Cost of Project Completion. The cost of Installation of the new sewer line replacement project is estimated to be $325,750 The project is expected to reduce excessive wastewater flows to the treatment plant from I&I and reduce the amount of water pumped to the retention pond. Therefore, this project will reduce the rate that the water from the retention pond is fed to the treatment plant.

Estimated Cost of Project Completion. The total cost of the Compliance Project is estimated to be $323,000. Due to the uncertainty associated with estimating construction costs at a planning level, the engineer’s opinion of cost included below is an estimate and includes a 20% contingency. Individual task cost estimates are provided in the table below. 1 Mobilization (12%) LS 1 $23,000 $23,000 2 4- to 6-inch Pipe Burst LF 335 $100 $34,000 3 Dig and Replace LF 40 $100 $4,000 4 6-inch cast-in- place pipe (CIPP) LF 265 $60 $16,000 5 Clean and closed circuit television (CCTV) LF 265 $15 $4,000 6 Post Inspection LF 265 $5 $1,000 7 Traffic Control LS 1 $10,000 $10,000 Item Description Units Quanti ty Unit Cost Total Cost 8 Erosion and Sediment Control LS 1 $10,000 $10,000 9 Lateral Replacement (less than 6 feet deep) EA 12 $7,200 $86,000 10 Manholes EA 2 $10,000 $20,000 Subtotal: $208,000 Contingency (20%): $42,000 TOTAL CONSTRUCTION: $250,000 Facilities Design (10%): $25,000 Construction Services (15%): $38,000 Administration and Legal (4%): $10,000 TOTAL PROJECT: $323,000 The proposed Compliance Project will reduce infiltration and inflow (I/I) entering the SSCS. Reducing I/I reduces peak wet weather flows entering the WWTF which will result in greater treatment effectiveness. Improving treatment effectiveness by reducing peak wet weather flows will help eliminate discharge violations to the Eel River (receiving water). Projected improvements to the effectiveness of the WWTF will be supplemented by construction of a new WWTF and rehabilitation/repair of a larger portion of the SSCS as described in the Discharger’s CWSRF projects.
Estimated Cost of Project Completion. The goals of the Compliance Project are to prevent future ammonia and total coliform organism violations, as previously described. The Compliance Project, in total, is expected to cost in excess of $60,000; $54,000 of MMPs associated with this Order will be used to fund the Project. Phase I has an estimated budget of $20,000 and Phase II has an estimated budget of $40,000. More than one contractor will be doing the work, as it is expected to be completed in phases. Project construction of the ammonia probe is expected to be completed no later than January 2019, while construction and integration of the fourth blower will be completed by December 2020. The Project will lead to a reduction of ammonia and total coliform discharged to Salt Creek, which is tributary to the Sacramento River.
Estimated Cost of Project Completion. The anticipated cost of the Denitrification Pilot Study is $25,000, which includes $24,000 of suspended liability. Itemized Expenses:
Estimated Cost of Project Completion. The total cost of the WWTP modifications and optimization is estimated to be $177,973. Individual task cost estimates are provided in the table below.
Estimated Cost of Project Completion. The total estimated cost of the Ammonia/Nitrate Reduction Project is $23,757. Individual component cost estimates are provided in Table 1 below. Acquire Aeration Basin Maintenance Pontoon $16,000 Refurbish and Add Diffuser Tubes $7,757 7. Water body, beneficial use and/or pollutant addressed: The Ammonia/Nitrate Reduction Project should reduce effluent ammonia exceedances, with resulting water quality improvements in Salt Creek.
