RPA’s engineers specialize in groundwater source development and surface water supply and treatment, tailoring solutions to meet each community’s unique source water conditions. We design and implement water treatment systems in Montana that include conventional physical and chemical processes and integrate sustainable design practices that reduce energy consumption and chemical use while maintaining compliance with applicable water quality standards. We also help clients identify and secure water infrastructure funding through CDBG, MCEP, Rural Development programs, DNRC grants and loans, and the SRF Loan Program. From source identification and capacity evaluation to treatment plant design and process optimization, we deliver water systems that are efficient and built for long-term reliability while meeting stringent drinking water regulations.
