Lake Pend Oreille School District

Construction Value:



T-O Engineers has completed three water system improvement projects for the Lake Pend Oreille School District. The first project included design of a chlorination system and chlorine contact piping to provide disinfection as required by the Department of Environmental Quality (DEQ). The well supplying the school had tested positive for total coliform bacteria on a couple of occasions, requiring them to come up with a plan for providing adequate disinfection and chlorine contact time to meet DEQ’s 4-log viral inactivation requirement.

T-O prepared a letter report along with CT calculations for sizing the contact pipe gallery as well as construction plans for the improvements. This project was fast-tracked with design beginning in December and construction completed by January to minimize disruption to the school.

Following this successful project the School District hired T-O to prepare construction plans for upgrades to the Hope Elementary and Southside Elementary well houses.
