Risk Analysis and Failure Factors
Industry Failure Data:
23% of small businesses fail within first year (general business statistic)
Nearly 50% of new car washes "fail before opening" due to poor site layout
Primary failure causes: location selection, inadequate capital planning, environmental compliance issues
Common Failure Modes:
1. Location Misjudgment: Cheap land usually means poor performance - premium locations cost more but generate higher returns
2. Inadequate Maintenance Reserves: Equipment depreciation requires dollar-for-dollar reserves for future rebuilds (20-year replacement cycle)
3. Environmental Violations: EPA compliance failures can result in significant fines and operational shutdowns
4. Cash Flow Seasonality: 20-40% revenue variation requires working capital reserves
Environmental Compliance Requirements
Wastewater Management:
Wastewater discharge permits required in most jurisdictions
Water treatment systems: $15K-$50K for proper filtration and reclamation
Ongoing compliance costs: $3K-$8K annually for testing and waste disposal
Potential EPA violations carry $10K-$50K+ fines if runoff enters storm drains
