  • Inspections: Sanitary surveys and site inspections are conducted to evaluate the capability of a drinking water system to consistently and reliably deliver an adequate quality and quantity of safe drinking water to the consumer and to ensure compliance with state and federal drinking water regulations.
  • Engineering Plan Review: Conducts reviews of and issues permits for new construction and modification of public water systems including the source, treatment, storage and distribution facilities to ensure the quality and protection of drinking water.
