Overview

When a conventional tank and leach field will not work, that is our specialty. Wade's Plumbing & Septic designs and installs engineered septic systems for Santa Cruz County properties with steep slopes, shallow soils, high groundwater, rocky ground, small lots, or environmentally sensitive sites.

We handle site evaluation support, system selection, permitting coordination, installation, startup, and owner guidance. Clear recommendations before money changes hands.

The basics

What is an engineered septic system?

An engineered (or alternative) septic system uses advanced treatment and dispersal when a standard gravity system cannot meet county standards. Common options include:

  • Aerobic Treatment Units (ATUs): Compact treatment that produces cleaner effluent for difficult sites
  • Mound systems: Built-up sand beds where native soil is too shallow
  • Pressure distribution and drip systems: Even dosing across limited or irregular drainfields
  • Recirculating filters and media filters: Extra treatment before dispersal
  • Hybrid designs: Combinations tailored to the parcel, setbacks, and soil report

County Environmental Health requirements and a licensed designer or engineer drive the final design. We work with that process every week.

Tips for planning engineered septic work

Call us when you are dealing with:

  1. 01A failed or noncompliant conventional system that cannot be replaced in kind
  2. 02A vacant lot or rebuild that will not perk for a standard leach field
  3. 03Surfacing effluent, odors after laundry, or backups tied to a stressed drainfield
  4. 04An ADU, bedroom addition, or higher occupancy that outgrows the old system
  5. 05Steep San Lorenzo Valley or foothill parcels with limited usable area
  6. 06Real estate contingencies that require a path to a permitted system

How we work

How we deliver engineered systems

  1. Site and system review: We walk the property, review soil and prior reports when available, and explain realistic options.
  2. Design and permits: We coordinate with designers/engineers and Santa Cruz County Environmental Health so the plan matches what the site can support.
  3. Installation: Our crews install tanks, treatment units, pumps, controls, and dispersal components with care for access, slopes, and neighbors.
  4. Startup and handoff: We verify operation, walk you through alarms and maintenance, and leave you with a clear service plan.

Timelines depend on soil work, engineering, and permit review. We keep you updated so you know what is next.

Time and cost

Cost and next steps

Engineered systems cost more than a simple tank-and-field replacement because of treatment equipment, design, and site work. Ranges vary widely by system type, access, and soil conditions. We provide transparent estimates after we understand the site, and we separate what is known from what depends on engineering or county review.

Flat-rate pricing, quoted on site before work begins.

Ongoing maintenance matters: filters, pumps, blowers, and service contracts keep advanced systems healthy. We set that expectation up front.
