Advanced Wastewater Treatment for Homes and Businesses

Aerobic Treatment Units (ATUs) are modern onsite wastewater solutions designed to replace or upgrade traditional septic systems. By using oxygen and naturally occurring microorganisms, ATUs break down waste more efficiently, producing cleaner, odorless effluent that protects groundwater, surface water, and the environment.


We proudly install and service two of the industry’s leading systems: BioMicrobics FAST® and Norweco Singulair Green®. Both systems meet or exceed NSF/ANSI standards and are trusted worldwide for residential, commercial, and community applications.

How ATUs work

  1. Pretreatment & Settling – Wastewater enters a settling zone where solids sink, and lighter materials rise. Screens prevent trash from entering the treatment chamber.
  2. Aeration – Oxygen is introduced via a blower or aerator, encouraging the growth of aerobic bacteria that rapidly digest organic material.
  3. Biological Treatment – Specialized media and microbes further break down nutrients, organics, and pathogens.
  4. Clarification & Filtration – Solids settle out, and flow equalization maintains consistent treatment.
  5. Disinfection & Discharge – Optional chlorine, UV, or dechlorination systems provide additional protection before clear, odorless water is released.

Why choose an ATU?

  • Cleaner, safer effluent that exceeds environmental standards
  • Ideal for properties without access to municipal sewer lines
  • Reduces impact on drain fields and extends their lifespan
  • Suitable for residential, commercial, and community applications
  • Backed by warranties, certifications, and proven global use

ATU - Aerobic Treatment Unit requirements

  1. One acre of property or less
