Wastewater treatment is needed so that we can use our rivers and streams of fishing, swimming and drinking water. For the first half of the 20th century, pollution in the Nation’s urban waterways resulted in frequent occurrence of low dissolved oxygen, fish kills, algal blooms and bacterial contamination. Municipal wastewater treatment is the process of removing contaminants from municipal wastewater, containing household sewage plus some industrial wastewater.

There are different processes to treat municipal wastewater from physical to chemical and biological methods. Each process has several alternatives, especially biological treatment that varies from land treatment solutions to MBR (membrane bioreactor). Different factors affect process selection such as capacity or flow rate of sewage, local environmental protection laws, available land, capital and operating cost, availability of technical workforce, and final point of reuse or disposal. RWT has a vast experience in design and construction of different wastewater treatment plants that can provide the best solution for each specific client. Different technology from wetlands, lagoons, extended aeration, SBR, MBBR, MBR, etc., can be studied and the most competitive solution will be proposed to meet the client’s particular needs for each type of wastewater treatment plant.
