Full service septic in Skagit & Whatcom Counties and the surrounding area

Pumping, inspections, repairs, design, and new installations across Skagit County, Whatcom County, and the surrounding counties. Family-owned and operated since 2010, run by Michael Yeates and his sons. We take pride in quality work and in making sure you understand your system, not just what it costs.

What we do

All your septic needs
handled in one place

Because our designer is in-house and we run our own excavators, the same company can take a system from soil evaluation to design, permitting, installation, and every pump-out after that. Nothing gets lost in a handoff.

Up-front pricing

Our prices are published, on purpose

Most septic companies make you call to find out what a pump-out costs. Ours are right here: a standard inspection is $275, a 1,000-gallon pump-out is $575, an RV pump-out is $200, and a service call is $175. Bigger jobs get a real quote before any work starts.

Certified O&M provider

Washington State requires septic inspections

Every home or business in Washington served by a septic system needs periodic inspections: every year for most system types, or every three years if the system is conventional gravity, per WAC 246-272A-0270. Counties differ in how strictly they enforce it. Here in Skagit County the same schedule is written into county code as well (SCC 12.05.160).

Inspections keep your system working properly and catch problems while they are still cheap. We are a certified O&M provider: we do the inspection, explain what we find in plain language, and file the county paperwork.

Family-owned

Started in 2010, still a family operation

Tiger Tank was started by Michael Yeates as a resource for friends and family, and it still runs that way: Michael Yeates and his sons, a crew of well-trained technicians, and equipment we are honestly a little proud of.

The habit that built the business is education. From the beginning, Michael Yeates would spend an hour with people just explaining how their septic system worked. We still do free walkthroughs for new homeowners, and our techs are taught to answer questions, not dodge them.
