Stormwater Management Pump System: Choosing the Right One

Selecting the right stormwater management pump system is crucial if you want to control the water that runs off your land effectively. Whether you own a home or a business, a reliable pump system can help you avoid the costly consequences of water damage, flooding, and ongoing maintenance issues. 

At All Needs Plumbing, we have seen firsthand how the right pump system can transform a property by keeping stormwater safely and effectively moving away.

Why Stormwater Management Matters

Stormwater is the rainwater that runs off your roof, gutters, driveways, and other surfaces. Without proper management, this water can pool around your foundation, flood basements, or overwhelm drainage systems. An effective pump system works in conjunction with your gutters and drainage to collect and redirect water, preventing damage and keeping your property safe.

Managing stormwater isn't just about preventing flooding. It also protects water quality by controlling pollutants carried by runoff. Properly designed systems reduce erosion, prevent sedimentation in waterways, and help meet environmental regulations. For commercial properties, this is especially important to avoid costly fines and maintain community standards.

Types of Pump Systems and What Works Best for You

You’ll typically find two main types of pumps for stormwater management: submersible and pedestal pumps.

Submersible pumps sit underwater in a sump or pit. 

They activate automatically when water reaches a certain level, efficiently pushing water out. These pumps are great for tight spaces and are quieter since they operate underwater. Their sealed design protects electrical components from water and debris, which is common in stormwater. Submersible pumps are often preferred in commercial settings where large volumes of water need to be removed quickly.

Pedestal pumps are mounted above the water level, making them easier to access for maintenance. 

They’re ideal when you have dry space available and want simple servicing. However, they can be noisier and are generally less protected from environmental elements. Pedestal pumps are often used in smaller or less demanding applications.

For commercial properties, we often recommend pre-assembled pump stations made from durable materials, such as polyethylene or concrete. 

The stations are designed to handle a large amount of water, and they can be customised with either one or two pumps for added safety and reliability. Dual pump systems enable one pump to operate while the other serves as a backup, ensuring continuous operation during heavy storms or when the primary pump is undergoing maintenance. These stations often include features like built-in controls, alarms, and monitoring systems to optimise performance and alert you to issues.

What to Look for When Choosing Your Pump System

Choosing the right pump system isn’t just about picking any pump. Here’s what you should consider in detail:

Capacity

Your pump must be able to handle the volume of water your site collects during heavy rainfall. If it’s too small, you risk flooding and water damage. Oversizing wastes energy and increases costs. We assess your property’s runoff potential by calculating peak flow rates based on rainfall intensity, surface area, and drainage characteristics to recommend the perfect capacity. For example, a commercial site with large impervious surfaces will require a higher capacity pump than a residential home.

Durability

Stormwater often carries debris like leaves, twigs, sediment, and even small stones. Choose pumps made from materials that resist rust, such as stainless steel or heavy-duty plastics, so that they can withstand these conditions without frequent breakdowns. Pumps with vortex impellers or grinders can handle solids more effectively, reducing the risk of clogging.

Automation

Locate pumps that have sensors and float switches that activate them automatically. This saves you from manual operation and ensures your system works when you need it most, especially during sudden storms. Advanced systems may include variable frequency drives (VFDs) that adjust pump speed to match flow rates, improving energy efficiency and reducing wear.

Maintenance

Opt for pumps that allow easy access for cleaning and servicing. Regular maintenance keeps your system reliable and extends its life. We recommend professional servicing to avoid costly repairs down the track. Features like removable screens and easy-to-access control panels simplify upkeep.

Installation Location

Whether your pump is situated underground, in a pit, or above ground, it affects your choice. Submersible pumps are suited for pits or sumps, while pedestal pumps work well above ground. Site conditions and space availability often dictate the best option. Proper installation also includes ensuring adequate clearance around the pump inlet to prevent clogging and allow smooth water flow.

How Gutter Cleaning Ties Into Your Pump System

Your gutters are the first line of defence in stormwater management. If they’re clogged, water overflows and overwhelms your pump system. Keeping gutters clean ensures water flows smoothly into your drainage and pump system, reducing the risk of blockages that can cause pump failure or flooding.

Pro-Tip: Clean your gutters before it starts to rain to lower the chance of clogs and pump failure. You can avoid the need for repairs during storms by taking this simple step. Regular cleaning prevents leaves and debris from entering your sump or pit, which can damage pumps or reduce their efficiency.

Benefits of Installing the Right Pump System

Installing the right stormwater management pump system protects your property from floods, reduces long-term repair costs, and improves water flow control. You’ll also boost your property’s value and ensure compliance with local council regulations. 

From my experience, I’ve seen many clients avoid significant water damage simply by upgrading their pump system and maintaining their gutters properly. One commercial client in St George had recurring flooding issues until we installed a dual pump station tailored to their site’s runoff volume. Since then, they’ve had zero flooding incidents, even during heavy storms.

Additional benefits include:

1. Reduced insurance premiums due to lower flood risk.

2. Peace of mind knowing that your property is safe when it rains a lot.

3. Energy savings with modern, efficient pump technologies.

4. Improved environmental compliance by managing runoff and reducing pollution.

Pro-Tip: Consider installing gutter guards to minimise leaf and debris build-up. This reduces maintenance frequency and protects your pump system from damage caused by debris entering the sump or pit. Gutter guards also help keep water flowing freely, reducing pressure on your pump system and lowering energy costs.

Maintenance Tips to Keep Your Pump System Reliable

Regular inspections and prompt cleaning of your pump pit can prevent clogs and mechanical failures. We recommend having a professional inspect your home at least once a year, or after a significant storm has passed. This includes testing sensors, removing debris from the sump, and examining the pump’s mechanical components. Proper maintenance not only extends the life of your system but also ensures it operates efficiently when you need it most.

Furthermore, do not let the pump run dry, as this can cause it to overheat and break. Ensure float switches are free from obstructions and functioning correctly. If you notice unusual noises or reduced pumping performance, call a professional immediately.

FAQs About Stormwater Management Pump System
