Update: With an overwhelming response from the public to reconsider a requirement to have a certified plumber install free Ultra-High-Efficiency Toilet (UHET) Replacement Program, DWS has now decided to allow single-family homeowners to receive the UHET with just a commitment date for installation and before/after photos.
Bathroom toilets typically account for the most indoor water use in residential households. On average, toilets account for approximately 25 to 30% of the total indoor water usage in single-family residential homes. The replacement of these older model toilets with new, UHET represents a meaningful opportunity to improve water cost savings and conservation for DWS and its service customers.
Ordinance Number 2108, A Bill for an Ordinance Amending Chapter 16.20 of the Maui County Code, Pertaining to the Plumbing Code took effect on December 31, 1992. This ordinance establishes a maximum rate of water flow or discharges for plumbing fixtures and devices in order to promote water conservation. These devices include:
Faucets (kitchen and bathroom)
The maximum flow for toilets under the guideline is 1.6 gallons per flush, but there are now even more efficient toilets available today.
Under the new DWS UHET Toilet Replacement Program, the public may choose to replace older qualifying toilets with new, Environmental Protection Agency (EPA) WaterSense, ultra-high-efficiency toilets (UHET) rated at 0.8 gallons per flush (gpf).
Restrictions apply and toilet replacements are currently only available to single-family residential DWS customers.
