BOISE CITY OF LANDER STREET Wastewater Treatment Plant, Boise, Idaho

BOISE CITY OF LANDER STREET is a municipal wastewater treatment plant located at 825 North Lander Street in Boise, Idaho. It serves an estimated population of 122,600, placing it in the category of a medium-to-large agglomeration under US regulatory standards. The plant is situated inland, more than 50 kilometers from the coast, and its operations are integral to the local water infrastructure. As a US-based facility, the plant operates under the Clean Water Act, administered by the Environmental Protection Agency (EPA) and likely permitted through the Idaho Department of Environmental Quality. For a plant serving over 100,000 people, secondary treatment is typically required, with advanced treatment expected if discharging to sensitive waters. The regulatory framework ensures compliance with national standards. The plant's treated effluent ultimately flows into the Boise River, a tributary of the Snake River, which drains into the Columbia River and eventually the Pacific Ocean. This waterway supports diverse aquatic life and is used for irrigation, recreation, and municipal supply downstream. The plant's performance directly affects water quality in this important regional basin.

The plant discharges into the Boise River, which flows into the Snake River and then the Columbia River before reaching the Pacific Ocean. This watershed supports critical habitat for salmon and steelhead trout, species that rely on clean water for migration and spawning. The Boise River also provides drinking water and irrigation for the region, making the plant's treatment standards vital for both ecological and human health.
