Section 11-20-40 - Criteria and procedures for public water systems using point-of-entry devices
Current through February, 2024
(a) Supplier of water may use point-of-entry devices to comply with MCLs only if they meet all the requirements of this section.
(b) The supplier of water has the responsibility to operate and maintain the point-of-entry treatment system.
(c) The supplier of water shall develop and obtain the director's approval for a monitoring plan before point-of-entry devices are installed for compliance. Under the plan approved by the director, point-of-entry devices shall provide health protection equivalent to central water treatment. "Equivalent" means that the water would meet all primary drinking water regulations and would be of acceptable quality similar to water distributed by a well-operated central treatment plant. In addition to the VOCs, monitoring shall include physical measurements and observations such as total flow treated and mechanical condition of the treatment equipment.
(d) Effective technology shall be properly applied under a plan approved by the director and the microbiological safety of the water shall be maintained.
(e) All consumers shall be protected. Every building connected to the public water system shall have a point-of-entry device installed, maintained, and adequately monitored. Every building shall be subject to treatment and monitoring, and that the rights and responsibilities of the public water system customer shall convey with title upon sale of property.
