Construction Management I Services I Hazen and Sawyer Page 2 of 4 The [[Conner Creek CSO facility]], capable of treating up to two billion gallons per year of peak sewer overflow, was online four months ahead of schedule and within the original budget. During expansion of the [[Paerdegat Basin CSO Control Facility]], we oversaw construction of the deepest cutoff slurry wall in the area - 200 - feet deep and 1,900 -feet long - in a densely populated area with a groundwater table only 10 to 15 feet below grade. Hazen and Sawyer was chosen by the Town of Culpeper, Virginia to provide design, construction management and process optimization - services for the 6 -mgd Culpeper Wastewater Treatment Plant. The project integrates 5 stage BNR using cost effective above ground circular tanks, to ensure compliance with stringent effluent limits for nitrogen and phosphorous. Enhanced nutrient removal facilities under construction at the City of Waynesboro, Virginia's treatment facility include deep bed denitrification filters, UV disinfection, above grade 5 -stage BNR, screening and grit removal and solids processing. Hazen and Sawyer partnered with a local firm and together have provided complete design and construction phase services. To provide safe drinking water to the urban service areas of La Romana, N� San Cristobal, and San Francisco de Macoris, the National Institute of Water and Sewage of the Dominican Republic (INAPA) retained the Biwater /Sinercon Consortium for the Design -Build delivery of [[three 23- MGD Water Treatment Plants]] and associated infrastructure. In turn, Biwater U.S.A. retained Hazen and Sawyer to provide engineering design and construction management services for the project. For Detroit Water and Sewerage Department's 240 -mgd Water Works Park Facility we provided construction phase services as Owner's hit Representative for this design -build project, including oversight of design and construction, and the creation of training and O &M manuals. Following completion of planning and design, we performed construction administration and inspection services for expansion of the [[Neuse River WWTP]] to 60 mgd, including nine construction contracts encompassing improvements to various treatment processes, emergency power generation, and tertiary filter retrofits for nitrogen removal. In Leesburg, VA, we prepared a siting study, and subsequently provided design and construction administration services for two 3 -mg elevated water storage tanks. One of the tanks housed a booster pumping station http: / /www.hazenandsawyer.com/ work /services /construction -ma... 7/11/2012
