Utilities and Infrastructure Arkansas 3 Minutes Read ยท published February 10, 2026 Flag of Arkansas

Overview

Little Rock, Arkansas regulates wastewater discharges through a municipal sewer use ordinance and related wastewater utility rules that apply to businesses and industrial users. See the City of Little Rock Code of Ordinances for the controlling sewer use provisions and definitions [1]. This guide summarizes how limits are set, who enforces them, and practical steps businesses should take to comply.

Permitted Discharges and Common Parameters

The municipal ordinance regulates the character of wastewater that may be discharged to the city sewer system. Typical parameters regulated by sewer use rules include biochemical oxygen demand (BOD), total suspended solids (TSS), pH, oil and grease, and specific heavy metals. Numeric limits, monitoring frequency, and sampling methods are established in the City code or implementing permits and may be included in local industrial discharge permits.

  • Common regulated parameters: BOD, TSS, pH, oil and grease, cyanide, copper, lead, zinc.
  • Monitoring and recordkeeping requirements are typically required for industrial dischargers.
  • Permits or authorizations may be required before discharging process wastewater to the sewer.
Contact the utility before installing a new discharge connection.

Sampling, Monitoring & Reporting

Businesses should establish a sampling plan consistent with the ordinance and any permit conditions. Required elements commonly include sampling points, analytical methods, chain-of-custody, and record retention periods. If the City has an industrial pretreatment program, sampling and reporting schedules will be specified in permit conditions or by the wastewater utility.
