In many ways, the pump station is an underrated and often overlooked utility in day-to-day life and the everyday maintenance of business productivity. Pump systems are crucial to so many residences and commercial settings.
Pump stations control water levels and enable the transportation of water away or toward a source. Because they’re underground or out of the way, people often forget they’re there, tirelessly working away.
Plus, even looking at a pump station doesn’t give you a real understanding of how it does what it does—most likely because everything happens inside a casing or a ‘pit’ and most people are not pump pros.
In this guide, we’ll explain how pump stations work, what they’re made of and who you can contact for your pumping solutions.
What is a pumping station?
A pump station, sometimes known as a packaged pump station, is a storage/collection chamber that contains a pump set. The internal pump set is designed to transfer foul, stormwater or surface water to a nearby drain, manhole, or sewer.
Pumping stations are installed into a larger water/sewage network or series of pipes. Ordinarily, the network of pipes relies on gravity for the waste to flow into the main sewer. However, in low-lying areas or areas with higher fluid volumes, with the main sewer sitting on higher ground than the domestic sewage pipes, the fluid needs to be transported differently. This is where pumping stations are utilised.
What does a pumping station do?
Water pumping stations transport fluid and/or sewage from one site to another. Pump stations are integral parts of residential and commercial premises, with specific pump systems installed to deal with demand.
A pump station can impact the rate at which water flows, break down contaminants in wastewater and redistribute fluids where they need to go. Pumping systems can also be used inside factories to control the excess produced often known as effluent.
What pump stations cando is only limited by their design. Bespoke pump stations can be adapted and built to deal with niche requirements and a correctly specified pump can enable lots of needs are solved.
From removing excess water and sewerage from a new railway station to discharging washdown from a chocolate factory production line, pump stations are critical in many applications to keep operations running.
How are pump stations specified?
Pump stations are specified by calculating how much product has got to be moved, at what flow-rate and the distance and height it has to travel to point of discharge. The size of the storage tank can depend on what storage is required e.g., a housing development may need to have 24-hours storage capacity in the tank whereas a production line may only require a few hours storage as they have critical spares on-site for immediate repair.
Building regulations state that a pump station for housing requires 24-hour storage below the lowest incoming invert (this is the lowest pipe feeding into the tank). This prevents backing up the system in the event of a pump blockage/failure and gives engineers a day to get the issue resolved before it causes any inconvenience to the residents.
Pump stations can be specified as above ground or below ground, this can depend on a variety of factors such as water table levels in the ground etc.
How do pump stations work?
Above we’ve covered what pump stations do,but how do they do it? Pump systems are the middle-ground between the source and the final stage. They are made up of lots of different sections (that we’ll cover below), neatly combined to create one unit that transfers produce that enters into the tank to the point of discharge at the end of the rising main.
They are programmed to discharge the produce from the tank when it reaches a certain level, this is so that they are not constantly running and also can discharge at the specified flow rate for a controlled amount of time.
What different types of pump stations are there?
As mentioned, there are lots of different pumps such as grinder pumps which break down the larger products in the fluid before passing through the volute and up the rising main. Submersible pumps are most commonly used in pump stations but come in variations such as the grinder pump that are more accustomed to dealing with contaminants in the water such as sand or small refuse.
Interceptors are typically plastic or ceramic tanks installed before the pump system network or natural water flow and can catch and contain contaminants, allowing the remaining flow of water to be discharged safely. An interceptor is essentially a large trap that is inserted to filter the pollutants from runoff before they enter a watercourse or stream.
We don’t only deal in pump stations and the associated pumps, we deal with a large range of pumps for varying industries. We have provided a couple of examples below:
Heating pumps provide heat energy that is transferred from a source of heat or warmth to a destination called a heat sink, effectively ‘pumping’ warmth from one place to another.
Process pumps are typically designed for transporting produce on a production line and are most commonly found in the food production industry.
