    The water is then pumped through a 300-foot-long pipe system, eventually reaching a picturesque irrigation pond surrounded by lush foliage. A recent visit showed the 10-foot-wide wheel, positioned atop a charming three-story wooden-shingled structure, spun leisurely in a gentle breeze.

  3. Well drainage - Wikipedia

    en.wikipedia.org/wiki/Well_drainage

    The wells may be arranged in a triangular, square or rectangular pattern. The design of the well field concerns depth, capacity, discharge, and spacing of the wells. [1] The discharge is found from a water balance. [2] The depth is selected in accordance to aquifer properties. The well filter must be placed in a permeable soil layer.

  4. Raceway (aquaculture) - Wikipedia

    en.wikipedia.org/wiki/Raceway_(aquaculture)

    In a well designed system, the existing water in the raceway is largely replaced by new water when the same volume of new water enters the raceway. Self-cleaning can sometimes be achieved if the fish stocks density is sufficiently high and the water level is sufficiently low. For example, if trout are stocked at 20 kilograms per cubic metre ...

    The quality of the well water can be significantly increased by lining the well, sealing the well head, fitting a self-priming hand pump, constructing an apron, ensuring the area is kept clean and free from stagnant water and animals, moving sources of contamination (pit latrines, garbage pits, on-site sewer systems) and carrying out hygiene ...

  6. Ranney collector - Wikipedia

    en.wikipedia.org/wiki/Ranney_collector

    A Ranney Collector is a type of radial well used to extract water from an aquifer with direct connection to a surface water source like a river or lake. The amount of water available from the collector is typically related more to the surface water source than to the piezometric surface of the aquifer. [1]

  7. Retention basin - Wikipedia

    en.wikipedia.org/wiki/Retention_basin

    Storm water is typically channeled to a retention basin through a system of street and/or parking lot storm drains, and a network of drain channels or underground pipes.. The basins are designed to allow relatively large flows of water to enter, but discharges to receiving waters are limited by outlet structures that function only during very large storm eve
