Water Submetering

Financial Benefits of Submetering


Water Submetering BenefitsWhat is water submetering?

Water Submetering, also known as utility submetering, involves the installation of water meters to measure and bill each unit’s actual water use. Each unit pays for the water they consume every month. Submetering has been used since it was invented in the early 1920’s.

What are the financial benefits of water submetering?

If you are trying to recover operating expenses for your apartment complex, submetering is the answer. Submetering your property puts the consumption in the hands of the tenants who are now responsible for paying for their use. This will result in water conservative and reduce the overall consumption dramatically.

  • We typically see 15-30% water savings after Submeters are installed.
  • Submetering is instrumental in detecting leaks.
  • Common area water usage can be accurately measured and billed accordingly.
  • Real estate managers and owners no longer waste time dealing with water bills.
  • Submetering allows more consistent monthly cash flow for owners.

Bottom lineProperty owners no longer carry the cost of the water utility and tenants pay their fair share. This will be reflected in the operating budget. The return on the investment is usually seen within 12 months.

What is ‘RUBS billing’ and how can it help real estate that can’t be metered?

RUBS is an acronym for Ratio Utility Billing System. RUBS uses formulas to allocate utility costs for water when meters are not an option or if your investment dollars can be better utilized elsewhere. NES (National Exemption Services) provides a variety of RUB options and will outline the options in accordance with your goals. Please note: Some states and counties do not allow RUBS billing, contact us to learn if your county does.
