To supply water for human use and business use, infrastructure such as dams, water treatment plants, reservoirs, water towers, pipes and pumps are required. This key concept addresses the many components of water supply and infrastructure from water sources to wastewater discharge. Included are themes such as:

  • Dams and reservoirs
