The Low Impact Development Center, Inc., a non-profit water resources research organization, was formed in 1998 to work with government agencies and institutions to further the science, understanding, and implementation of LID and other sustainable environmental planning and design approaches, such as Green Infrastructure and the Green Highways ...
Early civilizations like the Babylonians dug cesspits below floor level in their houses and created crude drainage systems for removing storm water. But it was not until 2000 BC in the Indus valley civilization that networks of precisely made brick -lined sewage drains were constructed along the streets to convey waste from homes. [ 2 ]
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.

They consist of a swaled drainage course with gently sloped sides (less than 6%). [21]: 19 Bioswale design is intended to safely maximize the time water spends in the swale, which aids the collection and removal of pollutants, silt and debris. Depending on the site topography, the bioswale channel may be straight or meander.
Beginning in the 20th century, designers of industrial and municipal sewage pollution controls typically utilized engineered systems (e.g. filters, clarifiers, biological reactors) to provide the central components of pollution control systems, and used the term "BMPs" to describe the supporting functions for these systems, such as operator training and equipment maintenance.
The Victorian gutter was an ogee, 115 mm in width, that was fitted directly to the fascia boards eliminating the need for brackets. Square and half-round profiles were also available. For a brief period after the first world war , asbestos-cement guttering became popular due to it being maintenance free: the disadvantages however ensured this ...
