Did you know that Laredo, Texas, once faced drought conditions so severe that city-wide water restrictions cut usage by nearly 30%? In a region where every drop counts, operating a car wash is a responsibility. It requires strict adherence to local ordinances and environmental regulations.
As water conservation becomes increasingly vital in South Texas, especially during drought conditions, understanding the City of Laredo’s rules on water use and wastewater management is essential for both business owners and environmentally conscious customers.
This article explores the key ordinances, relevant entities, and best practices that define responsible car wash operations in Laredo.
Water Conservation Ordinances Affecting Car Washes
Laredo’s municipal code includes robust water conservation measures, especially during droughts. The city’s Water Conservation Drought Contingency Plan is activated in stages, with each stage imposing stricter water use restrictions. As of July 2024, Laredo entered Stage 3 of its plan due to severe drought and low reservoir levels, as mandated by Ordinance No. 2019-O-139.
Key points for car wash operators and customers:
- Washing vehicles at home is restricted: Residents may only wash vehicles before 8:00 a.m. and after 8:00 p.m. on designated days based on their address number. Even then, washing is only allowed using a hand-held bucket or hose with a positive shutoff nozzle to minimize water waste.
- Commercial car washes are exempt from certain restrictions. Car washes like Aqua Express Auto Wash can operate at any time, provided they comply with all applicable wastewater and water use regulations. This exemption recognizes the efficiency and environmental controls in place at professional facilities.
- Reporting and enforcement: The Water Conservation Division monitors compliance and encourages the community to report water waste. This collaborative approach ensures that water resources are preserved for essential uses.

Wastewater Management Requirements
Proper wastewater management is crucial for car washes to prevent environmental contamination and comply with both local and state regulations. The City of Laredo Utilities Department, in conjunction with the Texas Commission on Environmental Quality (TCEQ), sets the standards for wastewater collection, treatment, and disposal.
Key Wastewater Management Practices:
- Collection and Treatment: All spent water from car washes must be collected and treated to remove pollutants, pathogens, and solids before being released into the municipal sewer system. This protects public health and the environment.
- Grit Trap Installation: Car washes are required to install grit traps or catch basins to filter out sediment and debris from wash water before it enters the sewer. Regular maintenance of these systems is mandatory to prevent blockages and overflows.
- Prohibition of Septic Discharge: Discharging car wash wastewater into a septic system is strictly prohibited. All wastewater must be directed to the municipal sewer or an authorized treatment facility.
- Notification and Sampling: Car wash operators must notify the local wastewater treatment plant of their discharge and may be required to provide access for sampling to ensure compliance with effluent standards.
Entities Involved in Regulation and Compliance
Several entities oversee and enforce water use and wastewater management for car washes in Laredo:
- City of Laredo Water Conservation Division: Enforces drought contingency plans and water use restrictions.
- Laredo Utilities Department – Wastewater Treatment Division: Manages the collection and treatment of wastewater, ensuring compliance with state and federal standards.
- Texas Commission on Environmental Quality (TCEQ): Regulates environmental compliance, including wastewater discharge permits, grit trap waste handling, and air emissions.
- Local Plumbing and Building Departments: Enforce local plumbing codes and ordinances related to protecting the water supply and preventing backflow.
Best Practices for Sustainable Car Wash Operations
To align with both the letter and spirit of Laredo’s ordinances, car wash businesses should adopt these best management practices:
- Use water-efficient equipment: Modern car washes utilize high-pressure, low-flow nozzles and water recycling systems to minimize consumption.
- Maintain and monitor grit traps: Regular cleaning and proper disposal of grit trap waste prevent environmental hazards and ensure compliance.
- Educate staff and customers: Posting signs about illegal dumping and water conservation helps reinforce responsible behavior.
- Stay updated on regulations: Ordinances can change, especially during droughts. Businesses should monitor city announcements and maintain open communication with regulatory agencies.
- Document compliance: Keep records of all maintenance, notifications, and inspections to demonstrate adherence to local and state requirements.

Why Professional Car Washes Matter in Laredo
Given the city’s water scarcity challenges, professional car washes play a vital role in sustainable water management. Unlike home washing, which can waste up to 150 gallons per wash and allow untreated runoff into storm drains, commercial facilities are designed to use water efficiently and treat wastewater before discharge. This not only conserves water but also protects the Rio Grande and local groundwater from pollution.
