From engineered system design through installation, repairs, and ongoing maintenance — we handle your septic needs with the same standard of craft we bring to every build.
A note on septic pumping: Septic design, installation, repairs, and maintenance are our specialty — septic pumping is not a service we provide. If you need a tank pumped, we're happy to point you toward a licensed pumping specialist in your area.
Reach out by phone or form. We'll gather details about your property and what you need.
We visit your property for evaluation and perform perc testing if needed to inform design.
We develop your system design and coordinate all ADEQ and local permits on your behalf.
Your system is installed by our crew and inspected to code for long-term reliability.
We're a Northern Arizona company building systems for Northern Arizona properties. We understand the soil conditions, the elevation, the permit landscape, and what it takes to install a system that actually performs.
We diagnose accurately and recommend only what your property actually needs — nothing more.
One team from site assessment to final inspection — no handoffs, no miscommunication.
Rocky soils, sloped lots, high-elevation sites — we've worked it all across Flagstaff, Sedona, the Verde Valley, and beyond.
When you call 928 Construction, you talk to someone who knows your project — not a call center.
In most cases, yes. A percolation test determines how well your soil absorbs water, which directly informs the right system type for your lot. We handle this as part of our design process.
Most residential installations take 1–3 days once permits are in hand. The permit process can take 2–6 weeks depending on the county and system type. We'll give you a realistic timeline up front.
Slow drains can indicate a septic issue, but not always. We'll assess your system and give you an honest answer — whether it's a drain field problem, a line obstruction, or something else entirely.
Septic pumping is not a service we provide. We specialize in design, installation, repairs, and maintenance. If you need pumping, we can refer you to a qualified specialist in your area — just give us a call.
We serve Northern Arizona including Flagstaff, Sedona, the Verde Valley (Cottonwood, Camp Verde, Cornville, Clarkdale), Prescott, and surrounding communities. Not sure? Call us and we'll let you know.
Absolutely — new system design for vacant lots and new builds is a core part of what we do. We'll work with your lot, local codes, and ADEQ requirements from the ground up.
