Paige Gilliam | Linear Design finished water transmission main with numerous Lake Ontario Water Treatment Plant Phase 2 trenchless crossings including an 1,800-feet microtunnel. The microtunnel consisted of 1,800 LF of Technical Advisor | 48-inch steel transmission main within a 60-inch steel Onondaga County Water Authority | casing to cross a town-owned golf course. Oswego, NY, USA Responsibilities include settlement, buckling, and The Lake Ontario Water Treatment Plant (LOWTP) is buoyancy calculations, significant constructability a 60 mgd nominal capacity (72 mgd-rated capacity) considerations, evaluation of shaft locations, direct filtration plant. Phase 2 Clearwells & Backwash development of detailed design plans and Tank Project consisted of new finished water piping to specifications, and construction cost estimates. and from the two new clearwell tanks. Piping included 72-inch steel inlet piping (from the new finished water Rio Dell distribution box) and new 60-inch steel outlet piping to connect to the existing 60-inch steel PCCP finished Trenchless Engineer | water line. Paige was responsible for guiding the steel City of Rio Dell | Rio Dell, CA, USA pipe design calculations, drawings, and specifications. The City of Rio Dell Drinking Water Infrastructure Improvement Project consists of the replacement of Harrison Town-Wide SSES Improvements the City’s failing watermain of various pipe materials Phase 1B and diameters. Paige was responsible for designing six HDD installations during the construction phase, in Design Engineer | which the Contractor’s preferred installation method Town of Harrison | Harrison, NY, USA differed from the final design. The HDDs range from Harrison SSES Improvements addresses the Town’s 300 LF to 800 LF of 18-inch thru 12-inch HDPE and issue of I/I in the sanitary sewer system. The project FPVC. includes MH inspections and sanitary sewer inspection footage review to determine recommended Belmont Lift Station and Forcemain rehabilitation methods.
