One of the first things that comes to mind when designing a new or rehabilitated lagoon is treatment capacity. As engineers we often focus on functionality first. However, equally important is the ability to safely construct, operate, and maintain the facility.

Addressing lagoon safety measures early during design can also help during construction and installation of the lagoon liner and equipment. There are several elements that can be incorporated into the design of a new lagoon (or installed during the upgrade of an existing lagoon) to facilitate safe access where needed and assistance if an accident occurs—because no one wants to take a swim in a sewage lagoon due to lack of safety measures!
