These are my links for September 29th:

• The Invisible Circus -
• Network for the sustainable use of energy in water and wastewater treatment – The water that you drink and use to flush the toilet all needs to be treated to provide everyone with safe drinking water and to protect the environment. However, this treatment uses a large amount of energy (8,000 GWh) each year. This is equivalent to you running about 100 million tumble driers non-stop for a year.
• EnerNet, UK – EPSRC network – sustainable use of energy in water & wastewater systems – The Energy Network is designed to promote and inform the efficient use of energy in water and wastewater treatment, and identify opportunities for power generation within the water industry. It is a collaboration of academic institutions, the UK water industry, government departments and organisations involved in promoting improved energy management within industry.
• Promoting Energy Efficiency in Water and Wastewater Treatment | Water Energy Technology Team – The water and wastewater treatment sectors account for as much as 3% of electricity use in the U.S.
• The Interflush Water Saving Product – Welcome Page – Varyflush Ltd makes the Interflush™: A kit which fits on top of your WC siphon and connects to the front mounted flush handle.’The very definition of a sustainable product’Only flushes when the handle is held down, releasing the handle stops the flush (when pan is clear). Only uses exactly what water is needed. Any less and the toilet would need flushing again. That is why nothing can flush a toilet with less water.
