Commercial Septic Systems in the Greater Houston Area

Businesses outside city sewer lines need a wastewater system that meets regulations and handles real daily use. We design, permit and install commercial septic systems with tailored solutions for each property.

Overview

Commercial septic systems

01Commercial properties are different

A restaurant, a church, an office building and a small business all produce wastewater differently. Flow volume, peak loads and the type of wastewater determine the size and type of system. We evaluate your actual use so the system is sized correctly and complies with regulatory standards.

02What we do for commercial clients

  • Commercial septic system design
  • Permitting with the county or authorized agent
  • Installation of tanks, aerobic treatment units and dispersal systems
  • Plans that account for current use and room to grow

03One team from plan to final inspection

Having design, permitting and installation under one roof reduces delays and miscommunication on commercial projects, where timing matters.

Technical detail

The engineering behind it

Sizing
Based on the building use and expected daily flow, not a household estimate
Treatment
Often an aerobic treatment unit for a higher level of treatment
Dispersal
Drip or spray, depending on soil and available area
Approval
Permit through the county or authorized agent

Illustrative layout. Required separation distances are set by state rules and your county, and we confirm them for your property during the site evaluation.

  1. 1

    Wells and water lines

    Septic components must stay a required distance from water wells and water supply lines to protect drinking water.

  2. 2

    Property lines and easements

    Tanks and fields need minimum clearances from property boundaries, so the layout has to fit inside the buildable area.

  3. 3

    Surface water and drainage

    Streams, ponds and drainage paths need a protective buffer, and the field must not sit where water pools.

  4. 4

    Buildings, drives and slope

    The layout also works around the house, driveway, trees, slope and where the soil is suitable.

Schematic of the four components of the aerobic treatment process, per Texas A&M AgriLife Extension publication L-5302. Actual units vary by manufacturer.

  1. 1

    Pretreatment ("trash") tank

    Removes plastics and other solids that bacteria cannot break down, protecting the equipment downstream.

  2. 2

    Aeration chamber

    An air pump and diffuser supply oxygen. Aerobic microbes consume the waste, and rising bubbles keep the water mixed.

  3. 3

    Settling chamber (clarifier)

    Microbes that have done their work settle out. The settled material is returned to the aeration chamber.

  4. 4

    Final treatment and dispersal

    Treated water collects in a pump chamber and is sent to the drip or spray field. Spray systems add disinfection first.

FAQs

Commercial septic systems: common questions

Do commercial properties need a different septic system than homes?

Often, yes. Commercial systems are sized by the use of the building and the expected wastewater flow, and they may need aerobic treatment and specific permitting.

Can you work with my builder or contractor?

Yes. We coordinate with owners, builders and contractors so the septic work fits your project schedule.
