Stormwater pollution comes primarily from urban runoff from non-point sources and is one of the largest sources of water pollution in the United States. Common stormwater pollution sources are run-off from streets, lawns, farms, and construction and industrial sites. Many states around the country have already isolated stormwater as their leading source of surface water pollution and its effects on the environment are becoming more apparent.
As stormwater pollution stems from multiple sources scattered across large areas, complex and innovative solutions are required to adequately solve stormwater problems. AEWS Engineering, through its multidisciplinary approach involving technical expertise from a variety of fields, provides solutions to some of the country’s most complicated water quality problems.
Wastewater - Decentralized
Managed decentralized wastewater systems are viable, long-term alternatives to centralized wastewater treatment facilities, particularly in small, rural, and developing communities. In many of these communities, decentralized approaches are additionally often the most cost-effective. Decentralized wastewater systems often consist of septic tank/drainfield systems, drywells, leach trenches, sand filter system, and cluster systems.
Combined Sewer Overflows
Combined sewer systems (CSS) are designed to collect storm water runoff, domestic sewage, and industrial wastewater in the same piping for transfer to publicly owned wastewater treatment plants. Although once considered an engineering marvel, these systems contain one critical flaw that makes them one of the largest sources of water pollution globally. During rain events, these systems are designed to overflow excess effluent into public waterways resulting in massive environmental hazards. Nationally, billions of gallons of raw sewage are released into public waterways every year resulting in hundreds of thousands of illnesses.
Water Reclamation and Reuse
As the world ventures into the twenty-first century, many nations around the globe are running into serious water supply issues. Water reclamation and reuse is quickly becoming one of the most promising fields in environmental stewardship. The term describes a variety of techniques to utilize an otherwise lost, increasingly precious resource. Common applications include:
- Stormwater harvesting techniques where stormwater gets stored for use in later applications.
- Wastewater reuse techniques where wastewater treatment plant effluent gets diverted for agricultural purposes instead of being discharged into public waterways.
