Frequently Asked Questions: Fountain Hills
How hard is the water in Fountain Hills, AZ?
EPCOR's Chaparral City district, which serves Fountain Hills, reports hardness of approximately 18 GPG (grains per gallon) in its 2024 water quality report. That's well above the 10.5 GPG very-hard line. EPCOR's treatment process removes biological contaminants and meets all safety standards, but it does not remove the calcium and magnesium that cause hardness. That's what a softener is for.
Who provides water service in Fountain Hills?
Fountain Hills is served by EPCOR's Chaparral City district, a private regulated utility that has operated in the community since its founding. EPCOR also serves portions of Surprise, Litchfield Park, and other Phoenix metro communities. Fountain Hills water delivery is reliable and consistent. The hardness level is the primary water quality issue most residents want to address.
Why does my pool tile in Fountain Hills have so much white buildup?
Pool tile scale is caused by calcium carbonate deposits that accumulate when hard water evaporates at the waterline. At about 18 GPG, Fountain Hills water leaves a substantial mineral residue on pool tile, waterfalls, and fountains over time. A whole-home softener reduces the calcium load entering your pool, significantly slowing new scale formation. Existing deposits require professional acid washing or tile cleaning, but the softener prevents them from coming back.
