Utilities and Infrastructure Texas 3 Minutes Read · published February 05, 2026 Flag of Texas

San Antonio, Texas property owners and businesses must meet local sewer connection standards and discharge limits before tying into the public wastewater system. This guide explains who enforces rules, typical technical requirements, permit steps, and how to report or appeal decisions; official municipal code and utility rules are cited and current as of February 2026.

Standards for Connection and Discharge

Connections to the public sewer require compliance with size, material, slope and backflow prevention standards and may require pretreatment for industrial or commercial dischargers. New taps, lateral connections and extensions must be designed to the utility and city specifications and inspected before acceptance.

  • Connection design drawings, prepared by a licensed professional where required.
  • Approved materials and installation methods for laterals, cleanouts, and manholes.
  • Pretreatment and grease control for food service and industrial sources.
  • Inspection and testing (air/leak tests, CCTV where required) prior to utility acceptance.
Private service lines remain the owner’s responsibility until accepted by the utility.

The controlling municipal ordinances and utility rules set discharge limits (e.g., BOD, TSS, pH, prohibited discharges) and technical specifications; specific numeric limits and design standards are contained in the city/utility documents cited below.[1]

Penalties & Enforcement

Enforcement of sewer use rules and discharge limits is carried out by the designated utility or city department (for San Antonio this generally involves the municipal code authority and the local water/wastewater utility). Inspectors may issue notices, orders to cease discharges, or require corrective measures.

  • Monetary fines: amounts and per-day schedules are not specified on the cited page; check the ordinance or utility enforcement schedule for exact figures.[1]
  • Escalation: first, repeat and continuing offences are subject to progressive enforcement and may include daily continuing fines or injunctions as set by ordinance; specific ranges are not specified on the cited page.[1]
  • Non-monetary sanctions: compliance orders, mandatory corrective plans, suspension of service, and referral to municipal or county court.
  • Enforcer and complaints: the utility or city inspections unit handles investigations; use the city or utility complaint/inspection contact pages in Resources below.
  • Appeals and review: appeal procedures and time limits are set in the ordinance or administrative rules; if not listed on the cited page, they are "not specified on the cited page" and require consulting the code or utility rules.[1]
Failing to address prohibited discharges promptly can lead to service termination and court action.

Applications & Forms

  • Tap/connection application: name/number not specified on the cited page; submit to the city utility or the local water/wastewater utility as directed by development services.[1]
  • Fees: connection, inspection and capacity fees are set by ordinance or utility tariff and are not listed on the cited page.
