What is the purpose of a sump in wastewater systems?

A sump in wastewater systems is primarily designed to collect liquids, including wastewater, from various sources before it is pumped away for further treatment. The sump acts as a reservoir where these liquids can accumulate, allowing for efficient handling of the flow. This is particularly important in areas where gravity alone cannot facilitate the movement of wastewater, as the sump can help lift the water to a more suitable level for treatment and processing.

In the context of wastewater management, this function is critical because it ensures that the system can handle fluctuations in water volume and supports the effective treatment of wastewater. By centralizing the collection of liquids, sumps also make it easier to prevent flooding in basements or low-lying areas, contributing to overall system stability and safety.
