The sewage basin collects and contains wastewater before it is removed from a building's system by way of a submersible sewage pump. It is a critical part of any wastewater (sewage, effluent, sump) system. Commonly constructed with fiberglass or high grade plastic, basins are heavy duty containers. They come in a variety of system types (simplex or duplex), sizes and applications. Some basins operate with multiple types of pumps while others are designed expressly to be paired with a specific pump. Basins sit below grade while the pump itself sits at the bottom of the basin. How it functions is simple: wastewater enters the basin through an inlet pipe or port. The wastewater accumulates in the basin until it reaches a certain level, at which point your sewage pump will activate (by way of a float switch or preset control) and pump the wastewater through a discharge pipe out of the building to a municipal sewer or septic tank. A correctly sized basin is important to ensuring that the wastewater system and the pump itself runs smoothly and efficiently. For instance, a basin that is too small could fill up rapidly and contribute to improper pump cycling. If the pump turns on and off repeatedly, it will quickly burn out. Longer downtime between pump cycles keeps the pump cooler and results in longer life. In this blog we will walk you through the process of sizing a basin to fit your needs and application by working through a specific example. (more…)
