Federal Way's water supply and your plumbing

Lakehaven Water and Sewer District serves most of Federal Way and gets about 26% of its water from 22 wells in local aquifers, including the Redondo-Milton Channel and Federal Way Deep aquifers. [1]

The rest comes from the Green River through Tacoma's Second Supply Project, filtered at the Green River Filtration Facility and carried by a 34-mile pipeline Lakehaven helped build. [2]

Polybutylene-era homes in Federal Way: leaks and repiping

The median home in Federal Way was built in 1984, and 38% of homes predate 1980. Homes from that era were typically built with copper or CPVC supply, plastic drains, and in some homes gray polybutylene supply pipe, which is where leaks, low pressure and drain problems usually start as they age.

  • Galvanized steel supply (1900–1960)
  • Copper supply (1950–2000)

Federal Way plumbing questions

Can recurring clogs in Federal Way mean a sewer line problem?

Yes. When several drains back up together, the main sewer line is the likely cause, and a camera inspection shows whether it's roots, a sag or a break. Why it comes up in Federal Way: Older laterals under evergreens crack and take in roots.

When is a leaking water heater an emergency in Federal Way?

A leak from the tank itself won't stop and usually means replacement; turn off the gas or power and the cold-water valve, then call. Why it comes up in Federal Way: Tanks in 1970s–90s homes reach end of life.

Where does Federal Way's water come from?

Mostly Green River water through Tacoma's Second Supply Project, plus Lakehaven's local wells.

Is Federal Way water hard?

No, Green River and local well water are fairly soft.

Do Redondo hillside homes have drainage problems?
