Outfalls are places where a wastewater treatment plant discharges treated water into the environment. Water sources such as oceans and estuaries accumulate the highest percentage of wastewater discharge after treatment is completed. This is due to these water bodies consisting of elevated levels of dilution of which can be attained. Experts have theorized on whether or not this process is economically sustainable for the long-term. Most of which centers on the harmful effects done on the coastal and marine ecosystems from the contamination. For this reason, outfall alternatives are being considered for the location to where industrial facilities can discharge their wastewater.
