Composting and Dry Toilets

We design and supply modern porcelain toilets that are odour-free. These separate urine from solids and help compost the solids.

Over time, the system creates a small amount of well-cured worm compost for your garden, along with a healthy flower bed.

Our designs separate urine from toilet solids and treat both so they can safely grow plants. The systems remove and recycle phosphorus and other pollutants from urine — without harsh chemicals.

Reed Beds for Sewage Treatment

We use reeds, flowers, and willow trees to naturally treat domestic wastewater. Often, no pumps are needed.

Our reed bed systems fit into small suburban gardens. They can even form part of a formal flower garden.

Grey Water and Water Recycling Systems

Treated grey water can be recycled back into the house for toilet flushing.

Herr reed bed systems for this are often small enough for suburban gardens. They can cut mains water use by up to 30%.

Systems like these save water and recycle it. They will become more important during long summer droughts in the future.

Rainwater Harvesting

Reducing mains water usage and water charges

We design and supply rainwater harvesting systems for flushing toilets in the home.

Our systems work well for buildings or houses with no garden or yard space. They are often used when updating narrow terrace houses or building new homes in busy urban areas. Find out more about rainwater harvesting.
