South West Water - Regensw
Energy Efficiency at South West Water by Alan Burgess, Energy Manager
SWW at a glance •We provide drinking water to 97% of homes in the South West
• We are reducing carbon emissions through energy efficiency and by generating energy from renewable sources.
• and Sewerage services to 88% of homes • 99.95% of water complies with regulations for quality drinking water.
• but we are a big energy user…
• We have 1.6 million customers in the South West region • We have 40 water treatment works with 15,000 km of water mains. • and over 9,000 km of sewers with more than 600 Sewage Treatment Works.
