Gray water: reusing laundry and shower water
Tucson has encouraged gray water reuse for years, and Tucson Water reimburses half the installed cost of a gray water irrigation system, up to $1,000, after the required workshop. A laundry-to-landscape system is the simplest; shower and sink systems involve more plumbing changes. A plumber can confirm drain routing and code requirements.
Installing a premium toilet
Premium 1.1 gpf toilets rely on bowl and trapway design, so pick one with a strong MaP score. Tucson's hard water leaves scale in fill valves and rim jets, so keep the jets clean. See toilet installation.
