Geoflow Offers Subsurface Drip Systems for On-Site Wastewater

Article excerpt

Subsurface drip is now being used in commercial, municipal, and residential on-site wastewater applications worldwide. The trend is driven by an increased understanding of design, advances in technology, and ecological and safety benefits.

Under conditions such as steep slopes, high water tables, small lots, and tight soils, subsurface drip slowly and uniformly releases effluent. The effluent stays underground in a pressurized grid system without overloading the soil. This system avoids deep percolation and runoff, keeping lakes, rivers, and groundwater safe from effluent. Humans and animals do not come into contact with the effluent either and are not exposed to pathogens.

Subsurface drip has been used to irrigate orchards for over 30 years. With critical advances in technology in the early 1990s, the technique started to catch on as an alternative method for on-site wastewater disposal or reuse. Historically, the primary challenges to long-term success have been, first, the potential for internal plugging and, second, intrusion of roots.

Geoflow, Inc., has found solutions to those problems. …
