What Pump Do You Need for a Domestic Bore?

Choosing the right pump is one of the most important decisions when installing or upgrading a bore system.

A properly selected pump ensures consistent pressure, efficient water delivery and long-term reliability. The wrong pump can lead to weak performance, higher running costs, or even system damage.

If you’re wondering what pump you need for a domestic bore, this guide will walk you through the key factors that determine the right setup for your property.

Why Choosing the Right Bore Pump Matters

Your bore pump is what turns groundwater into usable water for your property. It directly affects how your system performs day to day.

Water Pressure and Flow

The pump determines:

• how far your sprinklers reach

• how evenly your garden is watered

• whether your irrigation system performs as designed

If the pump is undersized, you may notice weak pressure and poor coverage. If it is oversized, it can cause excessive wear and inefficiency.

Efficiency and Running Costs

A well-matched pump:

• operates efficiently

• uses less electricity

• reduces long-term operating costs

Poor pump selection can increase energy usage and shorten the lifespan of the system.

Risks of Incorrect Pump Sizing

Common issues include:

• pumps cycling on and off too frequently

• overheating or premature failure

• inconsistent water delivery

This is why understanding what pump you need for a domestic bore should always be based on actual system requirements, not guesswork.

Types of Pumps for Garden Bores

There are several types of pumps used for domestic bore systems. The right choice depends largely on bore depth and application.

Submersible Pumps (Most Common)

Submersible pumps are installed inside the bore and operate underwater.

They are the most widely used option because they:

• handle deeper bores effectively

• provide consistent pressure

• operate quietly and efficiently

Most modern domestic bore systems in WA use submersible pumps.

Jet Pumps (Shallow Applications)

Jet pumps are installed above ground and draw water up from the bore.

They are typically used when:

• the water level is relatively shallow

• the bore is not very deep

However, they are less efficient for deeper applications.

Surface Pumps (Limited Use)

Surface pumps are similar to jet pumps and are used in specific scenarios where:

• water is very close to the surface

• demand is relatively low

These are less common in modern bore installations.

For more technical insight into pump types and performance, manufacturers like Grundfos provide useful guidance in their pump sizing resources.

How Bore Depth Affects Pump Selection

Bore depth is one of the most important factors when determining what pump you need for a domestic bore.

Shallow vs Deep Bores

• Shallow bores may allow for surface or jet pumps

• Deeper bores typically require submersible pumps

In many parts of the South West, bore depths vary depending on location and geology.

If you want to understand how depth varies across the region, Australind WBC explains this in detail on their water bore drilling page.

Pump Placement

Submersible pumps must be positioned:

• below the water level

• within the optimal production zone

Incorrect placement can result in:

• reduced performance

• air entering the system

• premature wear

Depth and Pump Capacity

The deeper the bore, the more work the pump must do to lift water to the surface. This directly affects:

• required motor power

• flow capacity

• system design

How Much Water Do You Need? (Flow Rate & Pressure)

Another key factor in choosing what pump you need for a domestic bore is your water demand.

Reticulation System Requirements

Your irrigation system determines how much water is needed.

This includes:

• number of sprinkler zones

• type of sprinklers used

• run time per zone

Flow Rate

Flow rate refers to how much water is delivered, typically measured in litres per minute.

Higher demand systems require higher flow rates.

Pressure Requirements

Pressure ensures water reaches all parts of your garden effectively.

Insufficient pressure leads to:

• uneven watering

• dry patches

• inefficient irrigation

Matching pump output to your irrigation system is critical for performance.

Key Factors That Determine the Right Pump

Choosing the right pump involves considering multiple variables together, not just one.

Data-Driven Pump Sizing

The most important point is this: pump selection should be based on actual bore performance, not estimates.

This includes:

• measured water yield after drilling

• actual depth and water level

• real irrigation demand

Manufacturers like Davey Water Products also emphasise this in their bore pump selection guides, highlighting the importance of matching pump specifications to real conditions.

Common Mistakes When Choosing a Bore Pump

Many performance issues come down to incorrect pump selection.

Oversizing the Pump

A pump that is too powerful can:

• waste energy

• increase wear

• cause system instability

Undersizing the Pump

A pump that is too small will:

• struggle to deliver adequate pressure

• reduce irrigation effectiveness

Ignoring Bore Yield

Installing a pump that exceeds the bore’s capacity can:

• draw water faster than it replenishes

• lead to performance drops or damage

Choosing Before Drilling

Selecting a pump before understanding actual bore conditions often leads to poor outcomes.

How Australind WBC Selects the Right Pump

Australind WBC takes a practical, data-driven approach to pump selection.

Based on Actual Bore Performance

Rather than relying on assumptions, pump sizing is determined after:

• drilling is completed

• water yield is measured

• depth and conditions are confirmed

Matched to Your Irrigation System

They assess:

• property size

• irrigation layout

• required flow and pressure

System Optimisation

This ensures:

• efficient operation

• consistent performance

• long-term reliability

Final Summary

So, what pump do you need for a domestic bore?

The answer depends on several key factors:

• bore depth

• water yield

• irrigation requirements

• system layout

Most domestic bores in WA use submersible pumps, but the exact model and size must be matched to your specific conditions.

Choosing the right pump ensures:

• strong, consistent water pressure

• efficient operation

• long-term system reliability

The most important takeaway is that pump selection should always be data-driven, based on actual bore performance rather than assumptions.

If you want your bore system to perform properly from day one, getting the pump right is just as important as the drilling itself.
