Sewer Connection & Repair Permit Requirements Page 1 of 6 1 When is a Sewer Permit Required? The City of Redmond requires that a side sewer permit be issued before work begins on all side sewers, including new installations, alternations, repairs, pipe lining, capping, relocating and removals. Emergency repair work is allowed without getting a permit in advance, but a permit must be obtained from Development Engineering Division the next business day. Anytime sewer work extends beyond the private property line (includes sidewalk, curb, and street), a Side Sewer Complex (ROW) permit is required. The following is a summary of work that requires this type of permit: • Repairs to existing private sewer laterals under sidewalks • Repairs to existing private sewer lines under streets (not city-owned) • All connections to public sewer mains and sewer service laterals • Relocations of existing sewer service laterals (from curb line to the main) • Connections to existing sewer service laterals extended to private property • Construction and/or extension of sewer service laterals to private property for future use • Repair of existing private sewer lines in the ROW 2 Who to contact before conduction of Sewer Connection or Repair Work? It is mandatory to dial 811 or call 1-[PHONE REDACTED] for utility locates at least 48 hours (two business days) before work begins.
