Septic Work in Northern California Requires a Licensed Hand


Lee One Construction is a licensed septic contractor serving Anderson, Redding, and the surrounding Northern California region since 2020, with 25 years of hands-on field experience and CSLB license #1063228.

We get called when a homeowner is building on a rural parcel with no sewer connection, when an existing system has failed or backed up, or when a septic inspection is a condition of sale. Slow drains, sewage odours, and soggy patches of grass are all signs that something is developing underground. We also handle straightforward tank pumps, repairs, and full replacements when a system has simply reached the end of its service life. Septic problems rarely surface until they are urgent, and by the time a homeowner notices the signs, the repair is almost always more involved than it first appears.

The Professional Septic Process, Start to Finish


We start every project with a full site assessment and soil evaluation. Where county rules require it, we conduct perc testing to confirm the land can support a system before any design work begins. Once the soil data is in hand, we develop a licensed system design and submit the complete permit application to Shasta County Environmental Health on the client's behalf. County coordination takes time, and getting it right the first time keeps the project on schedule. Excavation begins as soon as permits are approved. Our crew sets the tank to grade, trenches and installs the drain field to county specification, and inspects all components before any backfill goes back in the ground. Final county inspection confirms the system is code-compliant and ready to use. Every phase of that process is handled by Lee One Construction — no subcontracting, no handoffs, no gaps in accountability.

Common Questions About Septic Services in Northern California


  • How long does a septic system installation take in Northern California?

    Most residential septic system installations in Northern California take between two and five working days once permits are approved. The timeline depends on system size, soil conditions, and Shasta County inspection scheduling. Lee One Construction handles the complete process, perc testing, permit submission, excavation, and final inspection, so you won't need to coordinate multiple contractors.

  • What does a failing septic system look like in Shasta County?

    The most common signs are slow drains throughout the home, gurgling sounds in plumbing fixtures, sewage odours near the tank or drain field, and wet or unusually green patches of grass above the leach field. Any one of these symptoms warrants a call by the time multiple signs appear, the system usually needs more than a pump-out.

  • What permits are required for a new septic system in Shasta County?

    New septic systems in Shasta County require approval from Shasta County Environmental Health, including a passing perc test and an engineered system design. Lee One Construction prepares and submits the full permit application on the client's behalf, including all required documentation, so the project moves forward without delays caused by incomplete paperwork.
