Water reclamation is increasingly important for Illinois car wash operators from both environmental compliance and cost reduction perspectives.

What Is Water Reclamation?

Reclamation systems collect, treat, and reuse wash water instead of discharging to the sewer. Modern systems recycle 70-85% of all water used, dramatically reducing water consumption and sewer fees.

Types of Reclamation Systems

• Physical filtration: Remove solid particulates through screens and settling tanks
• Biological systems: Use bacteria to break down organic matter and contaminants
• Chemical treatment: Coagulating agents remove suspended contaminants
• Combination systems: Multi-stage for highest water quality reuse

Illinois Regulatory Requirements

• MWRDGC (Chicago area) wastewater discharge regulations
• Illinois EPA permits for facilities above discharge thresholds
• Local municipal water discharge permits where applicable
• Best Management Practice requirements for chemical handling

Financial Benefits

• 60-75% reduction in fresh water purchases
• Proportional reduction in sewer discharge fees
• Annual savings: $15,000-$50,000+ depending on volume and local rates
• Typical payback period: 2-4 years

Due Diligence for Existing Systems

• System age and maintenance history
• Current compliance status with all applicable regulations
• Odor issues (older biological systems)
• Underground tank integrity inspection
• Permit status and any pending compliance actions
