Plumbers in Anthem, AZ

EPCOR supplies the community's water, and its 2025 report traces where it starts. Most of it is Colorado River water carried from Lake Havasu by the Central Arizona Project canal, then piped eight miles to the Anthem Water Treatment Plant, a microfiltration plant. EPCOR also pumps groundwater from the Salt River Valley basin, and some supply can come from Lake Pleasant. Because river water and well water differ, the report says hardness and taste can change with the seasons.

The report gives hardness of about 18 grains per gallon, with 80 ppm of calcium and 29 ppm of magnesium in a 2024 sample. EPCOR says it does not treat for hardness, so those minerals reach every fixture and appliance in the house. To confirm which report covers your address, check the name on your water bill or search EPCOR's district map. Then tell us what you are noticing, from white crust on a faucet to a heater that rumbles.

Maricopa County's 2019 area plan records that development here began in 1998 as a master-planned community. Census estimates show how quickly it filled in: the median home dates to 2004, and about 79% of the roughly 9,500 homes were built between 2000 and 2009. Only about 2% are older than 1990, and around 85% of occupied homes are lived in by their owners.

When most homes on a street share an age, their plumbing tends to reach the same milestones around the same time. Original tank heaters, supply lines under the slab and fixture cartridges from that decade have now been working for well over 15 years. That is why a slab leak, a failing heater or a stiff valve is a common reason to call, and why we look at the age of the equipment before recommending a repair or a replacement.

Where a home sits on unincorporated land, building rules come from Maricopa County's Planning and Development Department, which regulates those areas of the county. The County no longer requires a permit to replace an existing water heater when the work follows the manufacturer's specifications, and it lists like-for-like plumbing repair and water, sewer or gas line repair among the minor permits it issues online. It also reminds owners to review their HOA's CC&Rs before making changes.

Wastewater is EPCOR's as well. Its rate schedule lists the district for both water and wastewater, and its local treatment facility filters wastewater through membranes before the effluent is reused on parks and golf courses. EPCOR's advice for the drains that feed that system is plain: keep fats, oils and grease out, because they cool and build up in your pipes and can cause a backup into the house.
