We are excited to have attended the Presby Environmental presentation on this new wastewater treatment technology. This new system is passive and requires no mechanical devices. It takes up a smaller footprint and allows for septic systems in areas where regular septic systems might not be approved. Marc Boogay Consulting Engineer may be able to help with layouts and percolation testing in support of this new technology, allowing development of otherwise unbuildable lots. The following link takes you to more information on how the Presby Enviro-Septic System works!
