This document presents a technical review of subsurface flow (SF) constructed wetlands as a decentralised wastewater treatment system. It supports that SF constructed wetlands can be a reliable and cost-effective treatment method for a wide range of wastewaters, with applications ranging from single family dwellings, parks, schools, and other public facilities to municipalities and industries.
