Gooding WWTP Improvements

This project consisted of multiple WWTP improvements. Due to the population growth, the City was in desperate need of a WWTP upgrade. The WWTP will be able to flow at 1MGD per day. The project consisted of rehabilitation of the existing headworks building, including installation of new roof, windows, doors, equipment, and hardware, and removal of interior walls. Replacement of equipment in the mechanical room and sludge pump rooms along with a new aspirating aerator pump for the sludge basin was completed. The work also included installation of new screen, new lift station, new process basin with SBR basins and post-equalization basin, new process building with sand filters and UV system, removal of the existing influent pipeline and installation of a larger influent pipeline and additional manholes and a dump station, and associated site work.

A recurring challenge our crews currently face is the extreme weather conditions in Idaho. The owner allotted weather days, but some days our crews worked in single digit weather, including concrete pours in less-than-ideal weather conditions. Due to a well-developed cold weather placement plan, GSE was able to properly pour concrete while using Bluetooth HCS TI Concrete Censors to monitor internal concrete temperatures, insulated concrete blankets, and ground heaters to make sure the concrete was at a healthy temperature. There were no issues with the concrete pours due to it freezing.

Additionally, GSE had to rock blast and remove over 3,000 yards of basalt rock. GSE went to the surrounding neighbors to provide early information about the sound and potential vibrations that might be felt and heard, and made people aware of the schedule and duration. Due to the great communication prior, there were no complaints when this work was being done. Seismic monitors were installed to ensure that existing buildings at the plant were not damaged.
