This lets pollutants settle out before the water soaks away or discharges slowly downstream. Ponds and wetlands. If you want to store water for longer, you can use ponds instead of detention basins. The surface area of stormwater wetlands should make up at least 1 percent of the area draining to the practice. Wetlands should have a length-to-width ratio of at least 1.5:1. Making the wetland longer than it is wide ensures that water entering the wetland receives adequate treatment. The HOA (now resident controlled) has now had it's detention basin inspected by the City. It was found to have been retaining water at a 6 foot depth.

And it makes a difference if this is a retention pond or a detention pond. Retention ponds hold storm water until the water is absorbed into the surrounding soil while Detention ponds hold storm water only temporarily and slowly discharge storm water into streams or wetlands at a flow rate that will not overwhelm the watershed.

The width to length ratio was also taken into consideration to maximize sediment retention and nutrient uptake. The detention pond has two inlet points, and most of the impervious part of the Texas AgriLife campus (6 acres) runoff (Figure 11) was routed to the pond via the two inlet flumes (Figure 12).
