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 ...
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.
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 water.
Well. A dug well in a village in Faryab Province, Afghanistan. The difference between a well and a cistern is in the source of the water: a cistern collects rainwater where a well draws from groundwater. A well is an excavation or structure created on the earth by digging, driving, or drilling to access liquid resources, usually water.
A domus, with impluvium numbered 7. The impluvium (pl.: impluvia) is a water-catchment pool system meant to capture rain-water flowing from the compluvium, an area of roof. [1][2] Often placed in a courtyard, under an opening in the roof, and thus "inside", instead of "outside", a building, it is a notable feature in many architectural traditions.
A drain-waste-vent system (or DWV) is the combination of pipes and plumbing fittings that captures sewage and greywater within a structure and routes it toward a water treatment system. It includes venting to the exterior environment to prevent a vacuum from forming and impeding fixtures such as sinks, showers, and toilets from draining freely ...
[77] Some pipe networks were made of ceramic – high-fired clay pipes – with a thickness of 5 mm or sometimes less and a length of 30 cm. [78] The peculiarity of these pipe networks was twofold: each pipe element, mainly those in terracotta, 30 to 100 cm long, had a narrowed shape in the middle, as if to create a "venturi" during the passage ...
The difference between pipes and tubes is a matter of sizing. For instance, PVC pipe for plumbing applications and galvanized steel pipe are measured in iron pipe size (IPS). Copper tube, CPVC, PeX and other tubing is measured nominally, basically an average diameter. These sizing schemes allow for universal adaptation of transitional fittings.
