What to know about plumbing in Boise
Most Boise water comes from wells
Veolia Water Idaho, the main water utility in Boise, says about 70% of its supply comes from underground wells and the remaining 30% is surface water from the Boise River. River water is treated at the Marden and Columbia water treatment plants. Because the mix varies by neighborhood, ask a plumber to test your water before recommending a softener or filter.

Check your customer-side service line
Veolia has said there is no lead in its own service system, but what lies on the customer side of each water meter was not known. The utility planned postcard surveys focused on buildings constructed before 1990 or of unknown age, and it asks customers to report their service line material through an online survey. Owners of older homes can have a plumber identify the pipe where it enters the house. Source: Boise State Public Radio on lead service lines in Idaho
