For Commercial, Industrial, and Institutional Customers

After years of analyzing data and water use patterns, EMWD is establishing water budgets and tiered rates for additional commercial, industrial and institutional (CII) customers.

The proposed rate structure is similar to one that has been used for EMWD’s residential and landscape customers for almost a decade. Individualized water budgets, coupled with inclining tiered rates, are an effective tool for encouraging water use efficiency.

EMWD is transitioning to budget-based rates in January 2019 for the following customer classes:

  • Churches and libraries
  • Mortuaries and cemeteries
  • Office buildings
  • Schools
  • Ag-horse farms
  • Looped multi-family residential
  • Looped landscape only

Water budgets for these non-residential customers will be based on industry-standard methodology, which considers factors such as the type of business, historical average use and amount of irrigated landscaping. For example, a small office building would be expected to have lower demand than a horse farm.

Water budgets are designed to give customers the water they need for efficient use indoors and out, and they help customers understand what is reasonable water usage. Customers who stay within their budget pay the lowest rates for water, but those who exceed it fall into the upper, more expensive price tiers.

Additional CII customers will be transitioned to water budgets and tiered rates over the next several years.

Please note: 

  • Non-functional* landscape areas installed before June 1, 2015, would be 70 percent of the evapotranspiration (ET) rate, the measure of irrigation needs based on rainfall, temperature and other climate factors.
  • Non-functional* landscape areas installed after June 1, 2015, would be 50 percent of the ET.
  • Functional* landscape areas would be 100 percent of the ET.

* Functional landscape areas include turf as a surface for recreation and sports fields. All other landscape areas are considered non-functional.
