Herr Ltd offers low energy and ecological water collection and treatment service. We co-design ecological water and waste water systems alongside architects and produce drawings, specifications and equipment for self-build domestic and small community systems. Our systems of Rain Water Harvesting use gravity and do not use electricity at all. Most conventional domestic sewage treatment systems are mechanically based. The Herr Waste Water Treatment Systems focus instead on the sustainable use of natural elements such as sunshine, reeds, flowers, shrubs, trees, and earth worms and are often designed to use no pumps or electricity at all. We also have a website dedicated solely to reedbeds: Reedbeds Ireland http://www.reedbedsirl.com/home
