Application process for a Group A public water system
A water purveyor must demonstrate the system's operational, technical, managerial, and financial capability to achieve and maintain compliance with relevant local, state, and federal plans and regulations.
A water system plan must be submitted to Clark County Public Health (CCPH). The scope and detail of the plan will be related to size, complexity, water supply characteristics, forecasted demand characteristics, past performance, and use of the water system. Washington Administrative Code 246-290-100 tells you what to include in your water system plan. Depending on the size and complexity of the proposed Group A water system, the Washington State Department of Health (DOH) may also be required to review and approve system.
After a Group A water system has been approved by CCPH and, if applicable, DOH, on-going monitoring is required to guarantee clean, safe water is provided to all well users. System purveyors have many responsibilities to up-hold. Annual operating permits are required. CCPH conducts a Sanitary Survey of each Group A water systems every 3-5 years.
The Washington State Office of Drinking Water has more information about system component requirements and continual operation and monitoring.
Sanitary surveys are water system inspections used to identify conditions that may cause sanitary or public health risks. DOH offers tips on preparing for a sanitary survey and are typically performed every five years.
