Public Water & Subdivisions Bureau
The Public Water & Subdivisions Bureau regulates public drinking water and subdivision facilities in Montana. The Bureau’s Public Water Supply Section assures that public health is maintained through a safe and adequate supply of drinking water. These functions are achieved by technical reviews, licensing, certifications, compliance monitoring, training and technical assistance. The Section also licenses operators of certain public drinking water and wastewater treatment facilities. The Bureau’s Subdivision Review Section reviews applications for proposed subdivisions to ensure compliance with the Sanitation in Subdivisions Act. In general, this includes reviewing the adequacy of water supply, wastewater treatment and disposal, solid waste disposal, and storm water control systems for parcels of land smaller than 20 acres, and for condominiums and recreational vehicle and mobile home parks, regardless of their size. Included in this review is the evaluation of water quality impacts from wastewater disposal systems in accordance with Montana’s nondegradation and mixing zone rules
