Dry pond on brook to reducing floods, near Děčín, Czech Republic. A detention basin or retarding basin is an excavated area installed on, or adjacent to, tributaries of rivers, streams, lakes or bays to protect against flooding and, in some cases, downstream erosion by storing water for a limited period of time.
A stormwater detention vault is an underground structure designed to manage excess stormwater runoff on a developed site, often in an urban setting. This type of best management practice may be selected when there is insufficient space on the site to infiltrate the runoff or build a surface facility such as a detention basin or retention basin .
The basins are designed to allow relatively large flows of water to enter, but discharges to receiving waters are limited by outlet structures that function only during very large storm events. Retention ponds are often landscaped with a variety of grasses , shrubs , and/or aquatic plants to provide bank stability and aesthetic benefits.
Percolation Trench. A percolation trench, also called an infiltration trench, is a type of best management practice (BMP) that is used to manage stormwater runoff, prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay.
Waste stabilization ponds consist of man-made basins comprising a single or several series of anaerobic, facultative or maturation ponds. [11] The presence or absence of oxygen varies with the three different types of ponds, used in sequence. Anaerobic waste stabilization ponds have very little dissolved oxygen, thus anaerobic conditions prevail.
The pros and cons of tap, bottled, filtered and more. Korin Miller. November 27, 2024 at 6:00 AM. How does drinking water from the tap compare to filtered or bottled options?
Detention basins are designed to temporarily hold runoff as a flood control measure; they are also called "dry ponds", "holding ponds" or "dry detention basins" if no permanent pool of water exists. Facultative lagoons are waste stabilization ponds providing stable stratified habitat for both aerobic organisms near the surface and anaerobic ...
In a complex arrangement, Slattery gave up a portfolio of 14 immigration detention facilities and adult prisons across the country as part of a $62 million sale, while buying back one division for $3.75 million: Youth Services International. As this new Slattery venture continued to grow in Florida, the old problems surfaced again.
