Source Capacity Testing Requirements

All wells that are proposed to supply water for domestic use or to be connected to a water distribution system shall first undergo a continuous source-capacity (pumping) test to determine the yield of the well.  If you wish to use this test for a water system, new home, or a planning project such as a subdivision, the test shall be witnessed by the Drinking Water Protection Services.
