Infiltration galleries may be used to supplement a storm sewer, by directing storm runoff from non-road areas.. While the catchbasins under sewer grates work well on swift-flowing surfaces like asphalt and concrete, heavy storm water flow on grass lawns or other open areas will pool in low areas if there is no outlet.
The ground or obstructions on the ground – jumpers would hit as a result of falling off. Alexander's goal was to increase the trampoline's safety by re-engineering the spring technology. In 1999, Alexander released his first prototype utilising glass-reinforced plastic rods, and the first commercial versions began selling in late 2004.
G-Cans, originally G-CANS PROJECT, [5] is the name of a civic group [6] [7] whose goal is to "transform the area surrounding the Metropolitan Area Outer Underground Discharge Channel and the Shōwa Drainage Pump Station into a new cultural and community hub, utilizing these regional resources to promote regional development"; "CANS" represents the idea that "anything can be done with the ideas ...
In her recent interview with Women’s Health, the Grand Hotel producer — who uses workout routines from trampoline fitness studio The Ness at least five days a week — explained her passion ...
A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.
A dry well receives water from entry pipes at its top. It can be used as part of a stormwater drainage network, an agricultural well drainage system or on smaller scales such as collecting stormwater from building roofs. It is used in conjunction with pretreatment measures such as bioswales or sediment chambers to prevent groundwater contamination.
The first rain gardens were created to mimic the natural water retention areas that developed before urbanization occurred. The rain gardens for residential use were developed in 1990 in Prince George's County, Maryland, when Dick Brinker, a developer building a new housing subdivision had the idea to replace the traditional best management practices (BMP) pond with a bioretention area.
Retention ponds such as this one in Dunfermline, Scotland, are considered components of a sustainable drainage system. Sustainable drainage systems (also known as SuDS, [1] SUDS, [2] [3] or sustainable urban drainage systems [4]) are a collection of water management practices that aim to align modern drainage systems with natural water processes and are part of a larger green infrastructure ...
