Drinking water plants are facilities where water is treated to make it portable. This process involves several phases such as catchment, mixing of coagulant & reactive substances, decanting & separation of sands, flocculation sedimentation, filtration, activated charcoal or chlorine. Drinking water plants are periodically clean the filters to remove particles that accumulate.

Drip Irrigation System delivers water at a slow rate directly to root systems. Drip irrigation reduces the need for pesticides. Drip irrigation systems are used with sand culture. These systems feeds each plant individually by use of spaghetti feed lines, sweat hoses or emitters. The drip irrigation system facilitates better control of crop water stress at predetermined growth stages compared with other irrigation methods. A typical drip irrigation system consists of components such as water supply source, control head, main pipe and submain pipes. A drip-irrigation system consists of emitters, lateral lines, main lines and controls. A drip irrigation system installed 15 cm below the soil surface is used to provide nitrogen and phosphorus. The design of a drip-irrigation system is based on the hydraulics of pipe flow.
