Construction sites often have large exposed surfaces that easily erode when exposed to wind and/or water. Once sediment has been dislodged it becomes suspended in the runoff from these sites carrying and depositing pollutant loads into storm conveyance infrastructure and receiving water bodies.
After a rainfall event, there are traditionally two ways that water is reintroduced to the natural water cycle. Firstly, the rainwater may enter a storm sewer that eventually connects to a nearby waterway. This means that any pollutants present on roadways or in landscaped areas eventually arrive untreated at waterways.
Flows generated after large storm events additionally possess the ability to overload the natural drainage system leading to bank erosion and flooding. Secondly, some municipalities have systems that combine both storm and sanitary sewers. This storm and sewage mixture is piped to a wastewater treatment facility before arriving at a waterway. During large storm events these combined systems can overflow resulting in the mixture entering local waterways, untreated.
Pressure has been put on municipalities to upgrade existing stormwater infrastructure in order to accommodate the increasing demands of expanding cities. If stormwater can be successfully managed onsite, the overflow and untreated runoff entering our waterways through conventional methods of treatment can be mitigated. Treating stormwater onsite allows the demands of municipalities to be met without overburdening or expanding existing stormwater infrastructure.
Emco is proud to offer various environmental protection products engineered to reduce the negative impacts of large flows and sediment loads generated by storm events.
