Tata & Howard completed a Sewer Feasibility Study for the Town of New Fairfield, CT to determine the feasibility of developing a sewer service area for the Town of New Fairfield town center/business district, municipal town buildings and schools, and other properties within the proposed sewer service area as well as transporting the wastewater to the City of Danbury’s Wastewater Treatment Facility. The assessment included an estimate of projected flows for all properties within the planned service area and a comparison of total estimated flows to available capacity at the Danbury Wastewater Treatment facility. Design concept plans for the planned sewer service area included determination of collection system sewers and pump station locations. Part of the study included an evaluation of potential routes for transporting flows from the Fairfield Town Center service area to the City of Danbury collection system for treatment.
Estimated project budgetary costs for the sewer service area collection system, pump stations, and transport to the City of Danbury along with a phasing and implementation plan were included in the final draft report to the Town of New Fairfield.
Throughout the course of the project, a number of meetings with the Town were held to obtain Town input and comments including one meeting at the completion of the initial assessment phase, one meeting at the completion of the concept design phase, and a series of meetings and presentations at Town Selectboard meetings to obtain public input during the roll out of the final report.
Tata & Howard provided preliminary and final design of 2.7 miles of gravity sewers, one main pump station, four remote, submersible pump stations, 2.3 miles of force mains, , and 4,000 linear feet of low pressure sewer. The project also includes identifying easements, land acquisition plans, preparation of permitting, and bidding assistance.
Preliminary design included survey, soil borings, preparation of base mapping, identification of utility requirements, a radio path survey and an opinion of probable cost.
Final design development includes final design of the main pump station, remote pump stations, gravity sewers, force main, and low-pressure sewers for connection to the City of Danbury collection system including site plans, profiles of force main and gravity sewers, pump station structures and chambers, electrical and controls, emergency generators, odor control, erosion and control plans, etc. Also includes design of the main pump station building designed to match the local aesthetic and mask it as a non-utility structure.
Construction Documents will be prepared by phasing construction under four contracts:
- Year 1 – Phase 1: Main Pump Station and force main for connection to the Danbury System and Collection System for the Town Center and commercial district (Sewer Sheds 2 [commercial],
4, 5 and 8); - Year 2 – Phase 2: Collection System connecting schools, police, and fire facilities (Sewer Sheds 1 and 2 [residential]);
- Year 3 – Phase 3: Additional Collection System connecting additional commercial properties, The Birches 55+ community, The Woods at Dunham Pond 55+ community, The Good Shepherd Lutheran Church, and potential future land development along Route 37 (Sewer Sheds 3, 6, and 7).
