For decades, the city of La Pine faced a critical public health and environmental challenge due to widespread reliance on aging and failing septic systems. Groundwater studies also revealed high nitrate levels in residential wells, a direct result of septic tank drain fields located near shallow wells.
In response, the city kicked off a $37.1-million decade-long effort to replace septic systems with a centralized sewer system and to install new potable water infrastructure. The project resulted in nearly 300 properties connecting to the city’s municipal sewer and water systems.
Comprehensive scope included improving the existing wastewater treatment facility with a new 20-acre effluent storage lagoon, irrigation pump station and two 100-acre center irrigation pivots. Crews also built a 500,000-gallon welded steel water storage reservoir with well pump improvements and installed transmission and collection systems across two neighborhoods.
Unanticipated cultural artifacts regularly appeared during construction, but rather than letting discoveries derail the schedule, crews remained flexible and shifted to other areas while artifacts were recovered.
