  2. Rainwater harvesting - Wikipedia

    en.wikipedia.org/wiki/Rainwater_harvesting

    configuration of domestic rainwater harvesting system in Uganda. [1]Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off.. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation, so that it seeps down and restores the ground w

  3. Rainwater tank - Wikipedia

    en.wikipedia.org/wiki/Rainwater_tank

    A rainwater tank (sometimes called a rain barrel in North America in reference to smaller tanks, or a water butt in the UK) is a water tank used to collect and store rain water runoff, typically from rooftops via pipes. Rainwater tanks are devices for collecting and maintaining harvested rain.

    en.wikipedia.org/wiki/Rainwater_management

    Rainwater harvesting (RWH) is the process of collecting and storing rainwater rather than letting it run off. Rainwater harvesting systems are increasingly becoming an integral part of the sustainable rainwater management "toolkit" [5] and are widely used in homes, home-scale projects, schools and hospitals for a variety of purposes including watering gardens, livestock, [6] irrigation, home ...

    en.wikipedia.org/wiki/Water_balance

    The water balance is also referred to as a water budget. Developing water budgets is a fundamental activity in the science of hydrology. According to the US Geological Survey: [4] An understanding of water budgets and underlying hydrologic processes provides a foundation for effective water-resource and environmental planning and management.

  6. Storm Water Management Model - Wikipedia

    en.wikipedia.org/wiki/Storm_Water_Management_Model

    Dry ponds temporarily store water after a storm, but eventually empties out at a controlled rate to a downstream water body. Sand filters generally control runoff water quality, providing very limited flow rate control. [20] A typical sand filter system consists of two or three chambers or basins.

  7. Total dissolved solids - Wikipedia

    en.wikipedia.org/wiki/Total_dissolved_solids

    Bottled mineral water usually contains higher TDS levels than tap water. Total dissolved solids (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form. TDS are often measured in parts per million (ppm).
