Buck, Seifert & Jost, Inc. was retained to evaluate, plan, and develop a conceptual design to replace the Ramapo Valley Wellfield (RVWF) Pump Station (PS) 4.16KV switchgear and pump control equipment due to age, increasing difficulty to obtain parts, and the increased safety features offered by the electrical equipment manufacturers. A conceptual design was completed… Continue Reading
Aquarion Water Company of Connecticut – Putnam WTP Settling and Filter Replacement (DAF) Value Engineering (March 2021)
Working together with Aquarion and Hazen and Sawyer (Hazen), BS&J reviewed 30% Design Documents including drawings, major equipment specifications, and the preliminary design report. A touchpoint list and short list of comments were prepared for consideration by Aquarion and Hazen including the evaluation of electrical options, consideration of phases/ stages of construction, available treatment processes… Continue Reading
Existing electrical switchgear at the RVWF pump station in Rockland County, NY is being evaluated. BS&J is preparing conceptual one-line diagrams, estimated costs, and recommendations to assist in the evaluation of an electrical upgrade with 4160V and 480V equipment.
BS&J is preparing the design of a temporary pumping operation and control strategy to allow this elevated storage tank serving a small pressure district to be offline for painting. Upgrading existing variable frequency drives, temporary emergency supply, fire flow, and surge relief are being considered.
SUEZ Water New Jersey, Inc. – 2,000lf 24-inch diameter Prestressed Concrete Lined Cylinder Pipe (PCLCP, SP-5) Replaced with Ductile Iron Pipe (July 2020)
Construction was completed by J. Fletcher Creamer & Son, Inc. (JFC) replacing approximately 2,000 linear feet of 24-inch diameter prestressed concrete pipe constructed in the 1970s with 24-inch diameter ductile iron pipe. The work included constructing insertion and extraction locations to allow the inspection of the remaining PCLCP utilizing the Xylem PURE Pipe Diver electro-magnetic… Continue Reading
Temporary storage and pumping requirements during the planned replacement of an existing 0.2MG potable water storage tank are being considered. BS&J was retained to assist with the design, permitting and construction of a new potable water storage tank. In August 2020, BS&J assisted with field flow testing and hydraulic modeling.
Additional CT has been provided by the replacement of existing 16” diameter water main pipe with larger 36” diameter pipe to provide four (4)-log inactivation of viruses. BS&J completed the design in April 2020 which included special consideration of thrust restraint for the larger diameter and the operating pressures in this pressure district. Construction was… Continue Reading
BS&J was retained to assist with the evaluation of the WWTP and recommend short term improvements. Components evaluated included: wet well pump station, aeration basins, clarifier, filtration, UV building, and electrical/stand by power.
The existing hydraulic model originally prepared by BS&J was updated for 2020 demands and operation. Several feasibility scenarios were evaluated related to interconnection supply and developed a preliminary control strategy.
Evaluated existing operation and designed improvements to allow this ground storage tank to be taken offline for inspection and repair while maintaining service. On-site inspections discovered new functionality at the well house supplying the tank, enhancing operational capabilities.
