Water demand exceeds supply, and household and industrial water supplies are prioritised over other uses, which leads to water stress. [8] Potable water has a price in the market; water often becomes a business for private companies, which earn a profit by putting a higher price on water, which imposes a barrier for lower-income people.
This road could be considered superior to any Roman road. [10] Roman roads varied from simple corduroy roads to paved roads using deep roadbeds of tamped rubble as an underlying layer to ensure that they kept dry, as the water would flow out from between the stones and fragments of rubble, instead of becoming mud in clay soils.
Sustainable water infrastructure is focused on a community's sufficient access to clean, safe drinking water. [8] Water is a public good along with electricity, which means that sustainable water catchment and distribution systems must remain affordable to all members of a population. [8] "Sustainable Water" may refer to a nation or community's ...
This is a list of countries (or regions) by total road network size, both paved and unpaved. Also included is additional data on the length of each country or region's controlled-access highway network (also known as a motorway, expressway, freeway, etc.), designed for high vehicular traffic. Unless otherwise noted, the data is from the United ...
The records cited included an ODEQ investigator writing “Over the years, the OTA has filled most of the low area with dirt, concrete, asphalt, wood, and various solid wastes from their operation.
Included are paved roads and other roads with a stabilized base, e.g. gravel roads. Roads also cover streets, bridges, tunnels, supporting structures, junctions, crossings and interchanges. Toll roads are also included.
In some areas, especially along the U.S. coast, polluted runoff from roads and highways may be the largest source of water pollution. For example, about 75 percent of the toxic chemicals getting to Seattle, Washington's Puget Sound are carried by stormwater that runs off paved roads and driveways, rooftops, yards, and other developed land.

Pollution and high sediment values in the water supply can ruin a crayfish habitat. This usually occurs from mining, timbering, and the use of unpaved roads by off-road vehicles, causing high levels of erosion that go directly into the water streams and supplies often found at the bottom of valleys where the Big Sandy crayfish lives and thrives ...
