Leader heads or conductor heads [ 1] are components of a roof drainage system which are known by different names, but they all mean the same. They are funnel-shaped elements, connected in most cases to a gutter, and from there to a downspout. [ 2] The downspouts take the water run off from the roof that is collected in the gutters to the ground ...
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.
The water drains into a gutter that is fed into a downpipe. A flat roof should have a watertight surface with a minimum finished fall of 1 in 80. They can drain internally or to an eaves gutter, which has a minimum 1 in 360 fall towards the downpipe. [11] The pitch of a pitched roof is determined by the construction material of the covering ...
Metal baffles at the roof drain inlets reduce the injection of air which increases the efficiency of the system. [68] One benefit to this drainage technique is reduced capital costs in construction compared to traditional roof drainage. [66] Another benefit is the elimination of pipe pitch or gradient required for conventional roof drainage piping.
A downspout, waterspout, [1] downpipe, drain spout, drainpipe, [2] roof drain pipe, [3] rone[4][5][6][7] or leader is a pipe for carrying rainwater from a rain gutter. The purpose of a downspout is to allow water from a gutter to reach the ground without dripping or splashing down the building structure. Downspouts are usually vertical and ...
Storm drain grate on a street in Warsaw, Poland Storm drain with its pipe visible beneath it due to construction work. A storm drain, storm sewer (United Kingdom, U.S. and Canada), highway drain, [1] surface water drain/sewer (United Kingdom), or stormwater drain (Australia and New Zealand) is infrastructure designed to drain excess rain and ground water from impervious surfaces such as paved ...
Chute spillway of Llyn Brianne dam in Wales. A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not ...
A French drain[1] (also known by other names including trench drain, blind drain, [1] rubble drain, [1] and rock drain[1]) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area. The perforated pipe is called a weeping tile (also called a drain tile or ...
