New Dwelling or Place of Public Occupancy Water Testing Requirements
Prior to the issuance of a building permit for a new dwelling or place of public occupancy, the applicant must submit evidence of a potable water supply either already existing on the property or legally available to the property (i.e. shared well or community water supply). In order to ensure that the water supply is potable (drinkable) and in sufficient quantity to support the daily needs of a household, the county requires a water quality test and a well pump test performed within the last 12-months.
Please view and print the following documents
Please include the completed pump test form and pump test recovery worksheet and the water quality test results in your building permit application documents.
