  • Bord na Mona. The Puraflo Wastewater Treatment System is a natural system that can be used for both on-site greywater and blackwater recycling. Filtered wastewater from a standard septic system is collected and then time dosed (pumped slowly) to percolate through a peat filter media; the treated effluent emerges as a ¬clear innocuous liquid,® according to the company. The treated water can be used to irrigate lawns, ornamental trees, and shrubs. Other advantages of this system come with leach field preservation and a reduced need for leach field area, allowing the construction of a septic system in challenging locations, such as too small a lot for the house size, poor percolating soils, or close to lakes and streams. 800.787.2356. www.bnm-us.com.
