Our Services
Herr Ltd designs low-energy rainwater harvesting systems, reed beds for sewage treatment, and ecological wastewater treatment systems that use plants, flowers, and trees.
We also supply composting systems for standard flush toilets, plus waterless toilets and urine separating toilets.
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.
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
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.

Working alongside Architects
We work with architects from the early stages of house design. Together we plan ecological water and wastewater systems.
We create drawings, specifications, and supply equipment. For bigger projects, we also do some on-site work.
The sooner we join the project, the better. This helps meet all the ecological and sustainable water management goals listed above.
The Natural & Living Elements
Our wastewater treatment systems use very little energy. They focus on natural plant-based systems and ecology.
Herr designs include:
- Sunshine
- Reed beds
- Various flowers and plants
- Willow trees
- Earth worms
Over time, composting and natural mushroom growth break down medicines (pharmaceuticals) absorbed by flowers grown with human urine.
