Rainwater harvesting. Basic 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 ...
A cistern (from Middle English cisterne; from Latin cisterna, from cista 'box'; from Ancient Greek κίστη (kístē) 'basket' [1]) is a waterproof receptacle for holding liquids, usually water. Cisterns are often built to catch and store rainwater. [2] To prevent leakage, the interior of the cistern is often lined with hydraulic plaster.
A rooftop water tower is a variant of a water tower, consisting of a water container placed on the roof of a tall building. This structure supplies water pressure to floors at higher elevation than public water towers. [1] As building height increases, the vertical height of its plumbing also increases. This produces a large water column and ...

[1][2] Often placed "inside", instead of "outside", a building, it is a notable feature in many architectural traditions.
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. A rainwater catchment or collection (also known as ...
The rooftop water towers store 250,000 to 50,000 litres (55,000 to 11,000 imp gal; 66,000 to 13,000 US gal) of water until it is needed in the building below. The upper portion of water is skimmed off the top for everyday use while the water in the bottom of the tower is held in reserve to fight fire.
Atrium (architecture) In architecture, an atrium (pl.: atria or atriums) [1] is a large open-air or skylight -covered space surrounded by a building. [2] Atria were a common feature in Ancient Roman dwellings, providing light and ventilation to the interior. Modern atria, as developed in the late 19th and 20th centuries, are often several ...
In AD 130, the Roman emperor Hadrian began the building of a Roman colony, the new city of Aelia Capitolina, on the site. About AD 135, he ordered that a cave containing a rock-cut tomb [c] be filled in to make a flat foundation for a temple dedicated to Jupiter or Venus. [3] [13] The temple remained until the early fourth century. [14] [15]
