When the ends are opened, the water flows through the pipe into the sewer or the river. Siphon irrigation of cotton at St George, Queensland. Siphoning is common in irrigated fields to transfer a controlled amount of water from a ditch, over the ditch wall, into furrows. Large siphons may be used in municipal waterworks and industry. Their size ...
A trench drain (also known as a channel drain, line drain, slot drain, linear drain, or strip drain) is a specific type of floor drain featuring a trough- or channel-shaped body. It is designed for the rapid evacuation of surface water or for the containment of utility lines or chemical spills.
A septic tank is part of a small-scale sewage treatment system often referred to as a septic system. Septic systems are commonly used to treat wastewater from homes and small businesses in rural and suburban areas. [9] It consists of the tank and a septic drain field. Waste water enters the tank where solids can settle and scum floats.
To make puddle, clay or heavy loam is chopped with a spade and mixed into a plastic state with water and sometimes coarse sand or grit to discourage excavation by moles or water voles.

An elevated water tank, also known as a water tower, will create a pressure at the ground-level outlet of 1 kPa per 10.2 centimetres (4.0 in) or 1 psi per 2.31 feet (0.70 m) of elevation. Thus a tank elevated to 20 metres creates about 200 kPa and a tank elevated to 70 feet creates about 30 psi of discharge pressure, sufficient for most ...
