Commercial livestock farming often results in an excess of manure and by-products that can contaminate groundwater or nearby waterways if not handled properly. BLA's patented Eco-Treatment method uses a combination of free-surface water wetland and a subsurface water wetland along with a vertical flow re-circulating media filter. This innovative approach combines the best of previous wetland approaches to result in a system that not only allows for the control of nutrient concentrations, but reduces odor as well.

• Eco-Treatment Wetland Technology for Agriculture
• Beanmeal Processing Facility Constructed Wetlands for Wastewater & Stormwater Run-off Treatment, Jackson County, Indiana

  • Client: Rose Acre Farms

    Rose Acre Farms, one of the world's largest egg producers, selected BLA to design two constructed wetlands to treat stormwater run-off and augment existing wastewater treatment system at its soybean processing facility. A 30,000-gpd constructed wetland system provides pretreatment of process wastewater generated by a soy bean processing facility. A second 60,000-gallon-per-day constructed wetland system treats up to ½-inch of rainfall generated over 4.5 acres. The system also treats water from their truck-washing operation. The Beanmeal Processing Facility system was one of the largest subsurface-flow constructed wetlands installed in the US for stormwater treatment. In 2006, the facility was awarded the Indiana Governor's Award for Environmental Excellence.

• Constructed Wetland Treatment & Disposal System, Hatchery Egg Farm, Jackson County, Indiana

  • Client: Rose Acre Farms

    This project involved design of a 20,500-gpd constructed wetland treatment and disposal system for a chick-hatching facility. Prepared plans and specifications for constructed wetland cells and subsurface drip irrigation soil absorption field. The system treats both sanitary and process wastewater. Also prepared permit application submitted to the State Department of Health.
