Residential Water Conservation

Residential water use includes water used indoors (bathing, cooking, cleaning, etc.) and water used outdoors (watering plants, swimming pools, washing cars, etc.) In Arizona, about 25% of the water supply is for municipal use, and most of this is residential. On average, each Sahuarita Water customer uses about 88 gallons per day, and as much as 70% of that water is used outdoors, especially in summer. Residents that incorporate water efficiency into everyday life will help to preserve water for future generations.

The following information is designed to help Sahuarita residents use water wisely and efficiently indoors and out.

Below are general water saving tips and ideas along with water efficient technologies.

Dishwashers, Sinks, Garbage Disposals

Dishwashers, sinks, garbage disposals and water treatment systems are the most common water users in the kitchen. Along with water saving practices, updated water efficient technologies can save a large percentage of water in the kitchen. Below are links to water-efficient kitchen technologies:
Residential Dishwashers
Garbage Disposals
Faucet Aerators
Water Purification System

Bathrooms
The bathroom is one of the most water-intensive rooms in the house. Some toilets are able to consume 27% of the entire indoor household water use; and a leaky toilet has the ability to waste up to 200 gallons a day! Sinks and showers use anywhere from 0.5 gallons per minute (gpm) for new water-efficient faucets to up to 5 gpm in older homes. This leaves many opportunities to implement water conservation practices and use water-efficient products:
Domestic Plumbing: Toilets
Domestic Plumbing: Faucets and Showerheads
Water Heating

Outdoor Residential Water Conservation

In the average American household, outdoor water use accounts for 58% of residential water use; and 80 to 90% of that comes directly from landscaping practices. This sizeable portion is usually due to large amounts of grass or turf, over-watering, or leaky or inefficient irrigation systems. Below are outdoor water-saving ideas and information:

Landscaping
Tucson AMA Drop Your Water Use Plant List sorted alphabetically by water use number (1-3). This list has been developed to assist participants in the Drop Your Water Use plant tagging program to choose plants by water use and group them into irrigation zones. The list contains all of the same plants on the TAMA Drought Tolerant/ Low Water Use Plant list.

Tucson AMA Drought Tolerant / Low Water Use Plant List sorted alphabetically by botanical name 

Supplemental Plant List – varieties and cultivars of plant species listed on the Tucson Low Water Use/Drought Tolerant Plant list that have gone through the approval process.

Denied Plants List – Plants that have been submitted for addition to the Tucson Low Water Use/Drought Tolerant Plant list that were denied and the reason for denial.

Deleted Plants List – Plants that have been submitted for deletion from the Tucson Low Water Use/Drought Tolerant Plant list and the reason for deletion from the list.

Plant Suitability List – These plants have not been grown in Tucson therefore they need to be tested for a minimum of 2 years to determine if they are appropriate for addition to the TAMA Low Water Use/Drought Tolerant Plant list. Growers will coordinate with the Tucson Botanical Gardens, Tohono Chul Park and the Arizona Sonora Desert Museum to test various plants for suitability. Plants deemed suitable can be resubmitted for addition to the TAMA plant list after testing.
