Septic Services in Spanaway, WA

Signs Your Spanaway Property May Need Septic Service

Changes in drainage, plumbing behavior, odors, or conditions around the septic system can indicate that an onsite sewage system needs professional attention.

• Slow drains throughout the property: Multiple slow fixtures may indicate a wastewater flow or septic problem.
• Sewage backups: Wastewater entering toilets, tubs, showers, or sinks requires prompt attention.
• Persistent sewage odors: Odors indoors or around septic components can indicate a system problem.
• Surfacing sewage or wet ground: Unexpected wastewater or saturated areas near the tank or drainfield should be evaluated promptly.
• Gurgling plumbing: Unusual noises from drains or toilets can occur when wastewater is not moving normally through the system.

If you notice these symptoms at a Spanaway property with an onsite septic system, contact Fast Adams to discuss the problem and determine the appropriate next step.

Private Septic Systems & Public Sewer in Spanaway

Spanaway is an unincorporated Pierce County community, so public sewer service comes from the Pierce County Sewer Division and onsite septic systems are regulated by Tacoma-Pierce County Health Department rather than a city government.

Pierce County includes Spanaway within its urban sewer service area, but sewer availability still varies by individual property. Some Spanaway properties are connected to the County sewer system, while others continue to rely on private onsite septic systems.

When Does Pierce County Require a Sewer Connection?

Under Pierce County Code 13.04.030, all properties within a utility local improvement district (ULID) must connect to public sewer. Outside ULID areas, new residential or commercial development in the urban growth area within 300 feet of an available sewer must connect.

Existing homes and buildings in the urban growth area that are within 300 feet of an available sewer and already served by septic are required to connect only when Tacoma-Pierce County Health Department determines that the failing septic system cannot be repaired or replaced, that a change in use exceeds the system’s capacity, or that continued use threatens public health. Required connections must be made within 60 days of the County’s written notice, and the old septic system must then be decommissioned under Health Department rules.

Can a New Septic System Be Installed in Spanaway?

It depends on the property and public sewer availability. Pierce County states that new onsite septic systems are not allowed in urban areas where sewer service is available. Properties without available public sewer may be eligible for onsite septic subject to Health Department approval and other County requirements, and new urban developments using interim septic systems are generally required to install dry sewer lines so they can connect when sewer reaches them.

Check Sewer Availability Before Major Septic Work

Before planning major septic repair, replacement, or installation work, property owners should confirm whether public sewer is available to the parcel and whether Pierce County connection requirements apply. Pierce County’s online sewer service area map is a good first step, and this can affect whether repairing or replacing an existing septic system is an appropriate option.

Septic Maintenance in Spanaway Lake Neighborhoods

Tacoma-Pierce County Health Department has been expanding routine septic inspection reminders throughout Pierce County based on environmental sensitivity and risk to human health. The department states that it started sending notifications in Spanaway Lake neighborhoods in 2025 and plans to eventually notify all septic system owners in Pierce County.

Property owners who receive an inspection reminder should use a septic service company certified to work in Pierce County. The service company completes the inspection and reports the results electronically to the Health Department.

The Spanaway Lake area is also one of the areas listed for the Health Department’s septic financial assistance program. Eligible owners can receive discounts on a routine inspection and, after that, on riser installation, tank pumping, and minor repairs. Eligibility should be confirmed with the Health Department, which asks owners to submit the application at least two weeks before scheduling service.

Reduced Inspection Frequency for Eligible Systems

Some qualifying gravity or pump-to-gravity systems may be eligible to move from a three-year inspection interval to a five-year interval. The Health Department’s current reduced-frequency program has specific requirements involving system type, ownership, permanent residency, baseline inspection status, training, property conditions, and an attestation process.

Does every Spanaway property use septic?

No. Pierce County’s urban sewer service area includes Spanaway, and some properties are served by public sewer. Other properties continue to use private septic systems depending on location, sewer availability, and property history.

Can a new septic system be installed in Spanaway?

It depends on sewer availability and the property. Pierce County states that new onsite septic systems are not allowed in urban areas where public sewer service is available. Where sewer is not available, onsite septic may be possible subject to Tacoma-Pierce County Health Department approval and applicable Pierce County requirements.

How often does a septic system in Pierce County need to be inspected?

Tacoma-Pierce County Health Department requires simple systems such as gravity and pressure systems to be inspected every three years. Complex systems such as community, aerobic treatment, and proprietary systems require annual inspection. Certain eligible gravity or pump-to-gravity systems may qualify for a five-year interval.

Does a septic tank need to be pumped every three years?

Not automatically. The inspection interval is separate from the need to pump the tank. The Health Department recommends pumping every three to five years depending on usage and household size, or when sludge and scum reach about one-third of the tank, and the findings of the septic inspection help determine timing.

What happens when a Spanaway property with septic is sold?

Tacoma-Pierce County Health Department requires a Report of System Status for Pierce County property sales involving septic systems.
