If big systems aren’t your specialty, we look at some options to get your foot in the large-scale-treatment-installation door.


Large-scale wastewater treatment systems are the bread and butter for Danny Brown, owner of KESS Environmental Services in Lowndesboro, Ala.

Not a fan of big pipe systems for large new-development neighborhoods, Brown eschews the inter-basin transfers, lack of groundwater recharge and high energy demands that accompany most of these systems. Instead, he prefers to keep the appropriately treated effluent close to its source through the use of drip irrigation as the final stage in the treatment cycle. 

“We are installing systems that are designed to eventually serve as many as 2,500 homes,” he says. That works out to a whopping 2 mgd design flow!

“Yes, we deliver an effluent clean enough for stream discharge, but we prefer the immediate benefits of groundwater recharge.” 

Brown’s typical big system is not typical in all regions nationwide. Sometimes called a community system, they employ a blend of components owned by both property owners and utilities. These systems can serve townhouses or detached single-family homes, provided each owner has title to sufficient land to contain a solids-separation tank in close proximity to the building. The homeowner owns and has responsibility for interior plumbing and the sewer running to the tank. Beyond that connection, a utility has ownership and maintenance responsibilities. 

The large onsite treatment systems Brown installs are often described as innovative and alternate solutions.
