Water Supply and Treatment
susceptible to corrosion
In 2017, the City of Rosenberg commissioned a study to assess the potential for corrosion in its pipe network before introducing treated surface water from an alternate source. The city was concerned that 70 miles of its 200-mile pipe network would be susceptible to corrosion due to differences in water quality. To provide for the health, safety and sustainability of the city’s water system, our team completed a pipe loop test, a system-wide flushing plan, a nitrification action plan, and consumer taste tests.
Since 35% of the city’s water lines are susceptible to corrosion, our team recommended and implemented a phosphate treatment. The phosphate’s chemical composition allows it to adhere to the inside of the pipes, creating a new internal surface that isolates the wall of the pipe and secures scale and deposits. The phosphate will serve to extend the life of the existing system and prevent corrosion. Additionally, extensive taste tests were held with city residents to ensure the community was satisfied with the final composition of chemicals used to treat the water sources.
