The Bunn Report is a series of whitepapers on the burning issues within the water utility industry today. The Bunn Report is new in 2011 and future reports will appear here. Older reports will be added to the Bunn Report archive.
Simon Bunn – Chief Technical Officer
After graduating with a Bachelor of Engineering (Electrical) Simon spent the next 21 years in control systems design, rising to become a partner in The Beca Group in 1999. In 2000 Simon used his experience of control systems and water treatment processes to design the complex software at the heart of the Aquadapt product, the world’s first commercially available real-time pump scheduling optimizer. In 2002 Derceto software for Wellington City was judged the top engineering project in New Zealand by ACENZ. In 2005 Simon was named the “Engineering Entrepreneur of the Year” at the New Zealand Engineering Excellence Awards.
»↓Reducing the GHG footprint at water and
wastewater utilities in the US and the UK.
February 27, 2011 | WHITEPAPER
Electricity consumption by water and wastewater utilities typically accounts for three percent of all energy consumption in the US and the UK. With national electricity production exceeding 3,000 million MWh/yr, this represents net annual consumption of about 90 million MWh. Between 90% and 95% of all energy purchased by a water utility is consumed by pumps; at the raw water intakes or wells; at the treatment plants; and at the booster pumping stations. As we will demonstrate, energy efficiency investments can yield excellent reductions in energy consumption and as a consequence also substantially reduce the carbon footprint of the utility. Case history data is presented showing that pump efficiency savings of 5% to over 25% in energy consumption can be achieved, with the inherent accompanying benefit of reducing the GHG footprint of the utilities.
