You may have heard the term, “wastewater flows downhill.” In this article, we will refer to this as gravity flow. In many cases, municipal wastewater systems have to pump the fluid uphill first. This presents many issues with regard to minimum flow velocities and pressure surge issues. This article describes the typical sewage pump station force main problems that can arise after startup.
