Sewer Permits

Print

All buildings, both residential and commercial, located within the Delta Diablo (District) service area are required to hook up to the public sewer, provided that one is available within 300 feet of the plumbing system of the premises.  Prior to hooking up a sewer or premises, approval and a permit must be obtained from the District.  Below is a map of the District’s facilities showing the location of the Permit Counter at our facility.  The hours of service are 8:00 a.m. to 5:00 p.m., Monday through Friday, except for public holidays.  Permit processing time varies depending on full scope of the project.  If you need additional information, please contact the Engineering Services Department at 925.756.1900 or permits@deltadiablo.org
