Phase one of this update determined that the existing Missouri River Treatment Plant should be rehabilitated or replaced due to age of equipment, public health risks, and operational safety issues. Plant replacement or rehabilitation costs were significant. The least costly scenario was to replace the capacity of the existing plant with high quality groundwater supplies if available. Test drilling of these wells has started in 1998. They are wall mounted with quick release brackets.
Regular maintenance is performed on all chlorination equipment and safety equipment.
Work orders are generated and tracked by computer. This is a local government owned and operated facility for the production of potable water for the City of Helena. The only reportable regulated substance for the RMP plan is chlorine. No more than two tons of chlorine are stored at this facility in ton cylinders. Normally only one cylinder is online at one time.
