  2. Intze principle - Wikipedia

    en.wikipedia.org/wiki/Intze_Principle

    Salbke Water Tower built to the Intze Principle. A water tower built in accordance with the Intze Principle has a brick shaft on which the water tank sits. The base of the tank is fixed with a ring anchor (Ringanker) made of iron or steel, so that only vertical, not horizontal, forces are transmitted to the tower.

  3. Groundwater model - Wikipedia

    en.wikipedia.org/wiki/Groundwater_model

    Groundwater models are used in various water management plans for urban areas. As the computations in mathematical groundwater models are based on groundwater flow equations , which are differential equations that can often be solved only by approximate methods using a numerical analysis , these models are also called mathematical, numerical ...

  4. Groundwater recharge - Wikipedia

    en.wikipedia.org/wiki/Groundwater_recharge

    Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface. Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. [1]

  5. 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.

  6. Multilevel groundwater monitoring systems - Wikipedia

    en.wikipedia.org/wiki/Multilevel_groundwater...

    The ports are connected using 3/4" NPT stainless couplings and 3/4" NPT steel drive pipe extensions. A Drive-Point Tip threads onto the first extension, or port, to be driven into the ground. The ports have a dual barbed stem that allows the connection of either 3/8" OD or 1/4" OD polyethylene or PTFE-lined tubing to create up to 3 or 6 ...

  7. Sequencing batch reactor - Wikipedia

    en.wikipedia.org/wiki/Sequencing_batch_reactor

    The tanks have a “flow through” system, with raw wastewater (influent) coming in at one end and treated water (effluent) flowing out the other. In systems with multiple tanks, while one tank is in settle/decant mode the other is aerating and filling. In some systems, tanks contain a section known as the bio-selector, which consists of a ...

  8. Underground storage tank - Wikipedia

    en.wikipedia.org/wiki/Underground_storage_tank

    "Underground storage tank" or "UST" means any one or combination of tanks including connected underground pipes that is used to contain regulated substances, and the volume of which including the volume of underground pipes is 10 percent or more beneath the surface of the ground. [1]

  9. Piping and instrumentation diagram - Wikipedia

    Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.
