Syracuse Secondary Reservoir

Project Overview

This project was bid during a period of material volatility when many budgets were unprepared for inflationary pricing. VanCon worked with the city to create alternative design engineering solutions, saving the city almost two million dollars and enabling the project to continue on schedule. VanCon excavated and poured a 37-AC-FT reservoir with underdrain to collect groundwater, installed 4,100 feet of wrapped perforated 6-inch and 220 feet of 12-inch HDPE piping to collect pond water and groundwater, and built a pump station with four 200 HP pumps. VanCon also installed 113,000 feet of 18-inch storm drain ADS, 1,700 feet of 24-inch ductile iron, 1,700 feet of 36-inch RCP, and 1,700 feet of 36-inch HDPE storm drainpipe into the road with a bore leading to the road tie-in. The project had extensive groundwater and dewatering was intensive throughout the excavation.
