Originally constructed in 1975 with major reservoir additions in 1986, the City of Humboldt’s Water Treatment Plant was later converted in 1996 to receive treated water from SaskWater’s Wakaw-Humboldt treatment plant. By 2017, much of the facility’s infrastructure had reached the end of its service life, prompting the need for a comprehensive upgrade. The $3.9 million project expanded reservoir storage capacity by 2,200 m³ (to a total of 7,300 m³) to serve a population of 9,000, replaced aged transfer piping, and modernized the facility’s electrical systems, controls, and distribution pumping infrastructure. Additional improvements included standby power generation, two new connections to the distribution system, and general building refurbishments.

A major challenge arose when a structural failure was discovered in one of the City’s primary reservoirs during inspection. Catterall & Wright quickly identified the cause, developed a cost-effective repair solution, and adjusted the project sequence to ensure uninterrupted water supply while the reservoir was offline. This project resulted in a modernized and resilient water distribution facility designed to meet the City’s needs for the next 20 years.
