Why Every Pump Basin is Not the Same?

Sewage treatment is a complex process that involves separating water from the numerous particulate matter and microorganisms that are present. One component of a sewage/water treatment system the help quickly and effectively separate various particles from the water is the pump basin.

What are the pump basins?

Pump basins in a sewage/water treatment system refer to those components that collect and store the contaminated water until it is ready to be treated. The objective of using a basin is three-fold:

  • Pump basins control the flow of sewage into the treatment system by holding-off the excess water until the system is able to treat it.
  • Basins can prevent the overflowing of contaminated water when there is rain by acting as a container that stems from the sewage flow.
  • Basins enable the heavier sludge and large particles to settle down at the bottom, letting only water pass through to the treatment system. This prevents dangerous large particles from getting stuck in your water filtering and treatment system at the later stages.

Why aren’t pump basins the same everywhere?

Pump basins differ based on the following criteria:

  • Usage – Pump basin models are specifically designed to suit residential, commercial, or industrial needs. This is because the amount of sewage and the nature of contaminants to be treated will be different in each type of building.
  • Sump pump pit size – The pump basin you buy must fit snugly into the pump pit. Otherwise, there is a chance of sewage overflow.
  • Components/accessories – Some pump basins also come with basin covers, discharge pipes, and lids. Others don’t have or need these accessories. This depends on your usage needs.
