The W&A Inspector observed construction activities and verified work was completed to the plans and specifications. The Inspector arrived on site and noticed the contractor was given an inaccurate set of plans. The contractor had excavated an area to tie-in to IEUA's trunk line through a non -approved method. The Inspector notified IEUA and the contractor immediately, preventing further work until the issue was resolved. • San Sevaine Basin Improvements ($5.4M) — As part of a larger Recharge Master Plan Update, this project installed a pump station into Basin 5 and laid interconnecting pipeline to upper basins.
