Water and Wastewater Treatment Works

Brief

For this contest I would like to see your photos of water and wastewater teatment works, including sewers. Although an unusual subject, a lot of these water treatment plants can be found in rural areas with beautiful views, so a good photo can often be achieved. Images could also show historical water treatment works, for example the Victorian sewers and pumping stations of London, which offer some great architectural views and superior workmanship. Technicians working in the water treatment plants can also be included. Please keep photos tasteful, as some views of wastewater treatment can be quite grim. Photos can be in colour or black and white.
