Service connections that will have static pressures exceeding 80 psi should have an individual pressure reducing valve installed in accordance with DSPS requirements. Contact DSPS at 608-267-9421 for further information on potential need for plan review. Replacement of service lines constructed of lead, or galvanized lines formerly downstream of lead, should be conducted in accordance with AWWA C810 standards to minimize potential consumer exposure to lead.
