Commercial/Industrial Water Allocations - Good to Know

• IRWD’s rate structure is site specific, taking into consideration production needs, number of employees, water use efficiency practices and irrigation needs.
  
• Many commercial businesses have separate water meters for indoor use and outdoor landscaping – in these cases, the budgets are handled separately.
  
• Commercial, Industrial and Institutional water budgets are referred to as a Base Index.
  
• The Base Index is determined from actual historical water usage for each individual customer.
  
• The monthly water bill is calculated by comparing actual usage with the base index.
• When a business grows, adds more employees, increases manufacturing output or serves more customers, customers may request a base index evaluation for possible adjustment of the base index.
