You may not be sure about the package sewer pump stations you need for your site or perhaps you are unsure whether you need one. Understanding your options can be very difficult but here are some answers to help you make the right decision.
What is a sewage pumping station?
A sewage system relies on gravity to deliver sewage or wastewater from a business or residential premises into the main sewer. When a gravity connection isn’t possible and the wastewater needs to travel horizontally or uphill to reach the main sewer, a pumping station is the answer.
Wastewater flows into the tank and once it has reached the predetermined level, the pump starts and transfers the water out to where gravity can take over. When it comes to deciding whether you need to install a pumping station on your site, it is helpful to understand how they function.
The well fills up
Wastewater or sewage travels from the building into the well. The level of sewage rises into the tank and when it reaches a predetermined point, the float switch is triggered to start the pump. How the pump does its job depends on the size of the pumping station and whether it has a dual or single pump system. Once the float switch is triggered, the pump starts pumping the waste, moving it out.
We recommend considering a dual pumping system where possible – where one pump deals with the inflows and the other pump provide backup in the unlikely event of a pump failure. The pump would then alternate duty with each cycle ensuring even wear.
Sewage is moved to the main line
Most sewer pump stations and pumps use centrifugal force to move energy from the motor of the pump to the fluid, moving the fluid from the pumping station to the discharge point where it joins the gravity network. After the tank has been emptied, the sewage pump will shut off automatically until the tank fills. The process is automatic.
Buying a pumping station
If any of the circumstances below apply to you, you will need to install a pumping station on your site: the ground level is too low to let the sewage pipes move downwards to the sewer; the sewer pipes pass over a ridge; the volume of waste from the site is enough that a regular system will be overloaded; the groundworks costs to overcome these issues would be very expensive and so on. By using a wastewater pump station, you can easily optimise the transfer of waste in a way that increases convenience and reduces cost.
Types of pumping stations
There are different types of package sewer pump stations that you can choose from. A package pump station is one of the most common types you can consider. They are cheaper, have a reduced confined space entry on a site, they are fast to install. However, they have a shorter life span, limited depth range, and are not usually structural units.
