Routine service

Septic Pumping and Maintenance Solutions

Longhorn Septic Service is your first call for routine septic tank pumping and preventive maintenance that keeps your system running reliably year after year.

Regular pumping removes accumulated solids before they overflow into the drain field, cause sewage backup inside your home, or trigger a costly system failure. Longhorn Septic Service recommends pumping every three to five years for most residential tanks, with more frequent service for high-occupancy households or commercial properties. Our technicians locate your tank, pump it completely, inspect the baffles and inlet/outlet pipes, and document the condition of your system at every visit.

Repair, don't replace

Septic System Repair and Restoration Solutions

Longhorn Septic Service is equipped to diagnose and repair failed or damaged septic components, restoring proper function without replacing the entire system when repair is the right solution.

Septic systems fail for many reasons - cracked tanks, broken baffles, collapsed distribution boxes, clogged effluent filters, or saturated drain fields. Longhorn Septic Service uses camera inspection and field testing to identify the exact point of failure before recommending any repair. We repair or replace tank lids, risers, baffles, distribution boxes, effluent filters, and drain field laterals. When a drain field can be restored through aeration or bio-treatment rather than full replacement, Longhorn Septic Service will tell you that clearly and honestly.

We install conventional gravity systems, aerobic treatment units (ATUs), low-pressure dosing systems, and mound systems for sites with challenging soil or high water tables.

Aerobic compliance

Aerobic Treatment Unit (ATU) Maintenance Solutions

Longhorn Septic Service is a licensed aerobic system maintenance provider, delivering the required inspections, chlorination, and reporting that Washington law mandates for all aerobic septic systems.

Washington requires aerobic treatment unit owners to maintain an active maintenance contract with a licensed provider. Longhorn Septic Service fulfills that requirement with scheduled quarterly inspections, chlorine tablet replenishment, pump and aerator checks, alarm testing, and state-required reporting. If your aerobic system is alarming, spraying improperly, or has lapsed on its maintenance contract, Longhorn Septic Service can restore compliance quickly.

What customers say

What Customers Say About Longhorn Septic Service

Longhorn Septic Service is rated highly by homeowners and property managers across Washington for reliable response, honest pricing, and work that resolves the problem completely.

"Our aerobic system alarm went off on a Friday afternoon. Longhorn Septic Service was at our property within two hours, identified a failed aerator, and had it replaced before dark. No weekend emergency fee, no runaround - just the problem fixed."

H
Homeowner
Washington

"I called three companies before Longhorn Septic Service. The others wanted to replace my entire drain field. Longhorn came out, ran a proper inspection, and repaired the distribution box for a fraction of the cost. Honest and thorough."

P
Property Owner
Washington

"Longhorn Septic Service has handled our maintenance contract for two years. They show up on schedule, send the state reports on time, and always let us know if something needs attention before it becomes a problem. Exactly what you want from a septic company."

Schedule Your Septic Service Today

Longhorn Septic Service is ready to inspect, pump, repair, or install your septic system now - before a developing problem forces an emergency call.

Septic problems do not resolve on their own. A full tank overflows. A cracked baffle contaminates your drain field. A lapsed aerobic contract puts you out of compliance with state law. The cost of acting today is always less than the cost of waiting.
