Water Softener & Filtration in Tempe

Whether it is a historic home near downtown and ASU or a newer build in South Tempe, Tempe's water is very hard and, in places, carries more than hardness alone. We tailor the right system to your home and have it professionally installed by licensed plumbing contractors.

What's in Tempe Water

Very hard, and more than just hard

Most of the Valley's water comes from the Colorado River, delivered through the Central Arizona Project canal, blended with the Salt and Verde Rivers and some local groundwater. As it crosses the desert it dissolves calcium and magnesium, so it reaches your tap very hard, and carries more than hardness alone.

How hard is Tempe water? +

Tempe water is very hard. Valley tap water commonly runs 12 to 20+ grains per gallon, among the hardest in the country, and your home's exact number is confirmed during a free on-site water test. Why Phoenix-area water is so hard →

Does Tempe use chlorine or chloramine? +

Valley water providers disinfect with chlorine or chloramine before the water reaches your home. Every Aera system carries carbon media that reduces both, along with the taste and smell that come with them.

Do I need a water softener and a reverse osmosis system in Tempe? +

They do different jobs. A whole-home softener treats the hard water at every tap, while a reverse osmosis system polishes the water you drink and cook with at the kitchen. Many Tempe homes benefit from both, and we'll advise what your home needs during your consultation.
