Introduction From the discussion of water pollution and water treatment in Unit II, we now transition to analyzing piping systems. This lesson begins with a presentation of fundamental hydraulic principles and then goes deeper into piping systems for water distribution and sanitary sewers. Hydraulics refers to the study of water, either stationary or flowing. An understanding of hydraulics is integral to environmental technology. Environmental technology deals with treatment of pollution for the purpose of a better and safer environment. Water distribution piping is needed to deliver safe, drinkable water from a drinking water treatment plant to customers. Following water use, sanitary sewer piping transports dirty water from customers to a wastewater treatment plant. A wastewater treatment plant treats water so that it can be discharged to the environment—typically to a river.
