Sustainable Wastewater Solutions
Under the natural biological cycle, human waste is recycled into into humus and plant nutrients that both improve soil fertility. This cycle is broken by centralised systems that transport sewage offsite to a treatment plant. After treatment these systems discharge to water bodies like our seas, rivers and lakes. The result is algal blooms from excess nutrients and death of aquatic life. The waste cycle means disposal to land using onsite  decentralised treatment.

Contact me for advice and design options for low cost on-site domestic wastewater treatment systems that are environmentally friendly and recycle human waste into a productive land use: humus as a soil amendment and surface irrigation for recycling of nutrients.
