Historically, people relied on harvested rain water to provide water for drinking, landscape watering, and for agricultural uses. Once urban areas started to develop, large, centralized water supply systems replaced the need to harvest water. More recently, people have become reacquainted with water harvesting, using it to provide water for home gardens, parking lot trees, multi-housing lawns, and commercial landscapes featuring desert adapted plants.
Pervious concrete as a paving material has seen renewed interest due to its ability to allow water to flow through itself to recharge groundwater and minimize stormwater runoff. This introduction to pervious concrete pavements reviews its applications and engineering properties, including environmental benefits, structural properties, and durability. Both hydraulic and structural design of pervious concrete pavements are discussed, as well as construction techniques.
