  2. Puddling (civil engineering) - Wikipedia

    en.wikipedia.org/wiki/Puddling_(civil_engineering)

    Later construction often used concrete to fill the cutoff trench. [3] 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. The puddle is laid about 10 inches (25 cm) thick at the sides and nearly 3 ft (0.91 m ...

  3. Sooke Flowline - Wikipedia

    en.wikipedia.org/wiki/Sooke_Flowline

    While the flowline remains, Victoria's water supply is now carried via Kapoor Tunnel. Leigh Hodgetts, CRD Waterworks superintendent, reported that the westernmost section of the flowline is still used to carry Sooke's water supply, via a 16-inch interconnecting pipe feeding the Sooke distribution system from Charters Creek to Sooke River Road. [2]

  4. Spillway - Wikipedia

    en.wikipedia.org/wiki/Spillway

    Water normally flows over a spillway only during flood periods, when the reservoir has reached its capacity and water continues entering faster than it can be released. In contrast, an intake tower is a structure used to control water release on a routine basis for purposes such as water supply and hydroelectricity generation.

  5. Slurry wall - Wikipedia

    en.wikipedia.org/wiki/Slurry_wall

    A slurry wall is a civil engineering technique used to build reinforced concrete walls in areas of soft earth close to open water, or with a high groundwater table. [1] This technique is typically used to build diaphragm (water-blocking) walls surrounding tunnels and open cuts, and to lay foundations .

  6. Water distribution system - Wikipedia

    en.wikipedia.org/wiki/Water_distribution_system

    An example of a water distribution system: a pumping station, a water tower, water mains, fire hydrants, and service lines [1] [2]. A water distribution system is a part of water supply network with components that carry potable water from a centralized treatment plant or wells to consumers to satisfy residential, commercial, industrial and fire fighting requirements.

  7. Prestressed concrete cylinder pipe - Wikipedia

    en.wikipedia.org/wiki/Prestressed_concrete...

    PCCP is typical manufactured according to the American Water Works Association (AWWA) standard C304. [1] PCCP is a composite structure that is composed of a concrete core, high-tensile prestressed steel wires, a thin steel cylinder, and mortar coating. [2] It is widely used globally in water systems infrastructure. [3]

  8. Backflow prevention device - Wikipedia

    en.wikipedia.org/wiki/Backflow_prevention_device

    Backflow means the undesirable reversal of flow of a liquid, gas, or suspended solid into the potable water supply; a backflow preventer is designed to keep this from happening. Points at which a potable water system connects with a non-potable water system are called cross connections .

  9. Plumbing - Wikipedia

    en.wikipedia.org/wiki/Plumbing

    Water systems of ancient times relied on gravity for the supply of water, using pipes or channels usually made of clay, lead, bamboo, wood, or stone. Hollowed wooden logs wrapped in steel banding were used for plumbing pipes, particularly water mains. Logs were used for water distribution in England close to 500 years ago.
