Although originally known for our work with wastewater treatment and water efficiency we now focus on building design and energy efficiency.

Water Efficiency

The Resource pages include free documents containing information on best practice. The AECB Water Standards and the Environment Agency document Saving Water In Buildings cover most aspects.

In 2005 with Andrew Warren and I set up NatSol to manufacture state of the art waterless toilets designed for allotments, churches and all sites without mains services.
