Presence of stagnant water on and around the site

Presence of stagnant water on and around the site

A substantial presence may be a large body of standing water such as a pond, a high density of small areas such as water standing in tyre tracks. If the standing water is contaminated wastewater then even small quantities should be considered as significant. Small puddles of rainwater that dry up after a day or so should not be considered a substantial presence.

General guidance: 
Stagnant water may include wastewater, rainwater, natural water bodies and standing water that remains after flooding. The presence of substantial quantities of standing water in and around a site, particularly near living areas and drinking water sources creates a risk to public health through faecal contamination (wastewater and run-off may often be faecal contaminated), the creation of vector breeding sites (for mosquitoes, flies etc.), drowning hazard etc. Although mosquitoes and other insect vectors may travel up to several kilometres from their breeding sites, the closer people are to the breeding sites the more likely it is that there will be contact with the vectors. For most concentrated settlements, standing water that is at least 30m from living areas is effectively outside the perimeter of the settlement.
