Tempe homeowners call Liberty for french drain & yard drainage because we're local to the Valley, licensed, and answer the phone 24/7. Tempe is an established East Valley city, mid-century and 1970s-80s homes near ASU with newer infill scattered through. That older housing stock means galvanized and aging-copper repipes, sewer-root work, and plenty of rental-property plumbing. We've done a lot of it. When we look at your place, you'll get the truth about what's failing, your options laid out plain, and a fair price upfront before we start.
Tempe's plumbing reality is defined by age and turnover. The neighborhoods ringing ASU, from the mid-century ranches near downtown to the 1970s and 80s builds in south Tempe, were plumbed with galvanized steel and early copper that's now corroding from the inside out. Galvanized lines clog with rust until pressure drops to a trickle, and we still pull original galvanized out of Tempe homes weekly. Add decades of rental turnover, where deferred maintenance compounds because no owner-occupant catches the slow problems, and you get homes where a single repipe finally resolves years of mystery low-pressure and discolored-water complaints.

How a Tempe french drain & yard drainage call goes
Read the water before we dig
We walk the lot, find the high and low points, and trace where monsoon runoff actually goes, not where you'd guess it goes. The fix has to start at where water collects and discharge somewhere it can safely leave, which on a sloped high-country lot is different than on a flat metro lot.
Build a drain that lasts
A proper French drain is a graded trench, perforated pipe, washed gravel, and filter fabric that keeps Arizona's fine silt from clogging it. We slope it correctly so gravity does the work, daylight or route the discharge appropriately, and tie in surface drains or channel drains where hardscape sheds water fast.
Protect the foundation and verify the flow
We aim the system to pull water away from the slab and foundation, then run water through it to confirm it actually carries the load before we backfill and finish. You see it work, not just take our word for it.
