  • Site plan showing building sewer, sewer main, cleanouts, and grades.
  • Engineered drawings when required for commercial or multi-family connections.
  • Fees or utility deposits where applicable.
Always confirm whether a licensed plumber or engineer is required before submitting plans.

Flood safety steps when connecting to sewer

In flood-prone areas of Laredo, installations must address backflow, elevation of cleanouts and manholes, and stormwater interaction. Install backflow prevention or check valves where required, and coordinate elevation of connections with floodplain regulations to avoid surcharge and basement flooding. For utility-specific flood-safety requirements and recommended devices, consult the City of Laredo Utilities guidance City Utilities[2].

  • Install approved backflow prevention devices where sewer backup risk exists.
  • Raise critical cleanouts and service connections above expected flood elevations where allowed.
  • Schedule inspections during dry conditions when possible to verify seals and elevations.
  • Keep records of permits and inspection reports for insurance and compliance.
If your property lies in a mapped floodplain, coordinate with Development Services before altering sewer elevations.
