Scientific Yield, Flow & Pumping Capacity Testing

Knowing how much water is sitting at the bottom of your bore is only half the battle; the real crucial factor is knowing how fast and how long that water can be drawn out without exhausting the source. Pumping a bore too aggressively can cause the water table to drop rapidly, pull in fine sediments, damage your pump, or even cause the underground aquifer to collapse.

Our Yield, Flow & Pumping Capacity Testing service provides a precise, scientific audit of your water asset. Whether you are purchasing a new rural property, expanding a commercial livestock operation, or meeting local council and water licensing requirements, we provide the definitive, hard data you need to manage your water security with complete confidence.

Our Approach To

Yield, Flow & Pumping Capacity Testing

At B&T Drilling, our approach to flow testing is rooted in strict hydrogeological measurement. We don’t just drop a pump down the hole for five minutes and give you an estimate; we conduct rigorous, controlled drawdown and recovery tests to observe how the aquifer behaves under sustained stress.

We bring advanced metering equipment and decades of field experience to your site. By tracking the exact correlation between the volume of water extracted and the time it takes for the water table to fully recharge, we calculate the absolute sweet spot for your system. Our goal is to give you an honest, independent evaluation that protects your expensive pump infrastructure from running dry while maximizing your daily operational water security.

How We Work

The Process

01

Static Water Level Baseline

Before any machinery is turned on, we measure the static water level of your bore. This establishes our starting baseline, showing exactly where the natural water table sits when the system is completely at rest.

02

Controlled Pumping & Drawdown Tracking

sing our specialized testing pumps, we draw water from the bore at a constant, metered rate over a specific time frame. We continuously monitor the “drawdown”—the exact rate at which the water level drops inside the casing during operation.

03

Aquifer Recovery Analysis

Once the pump is shut off, the most critical phase begins. We precisely log the “recovery time”—how long it takes for the underground aquifer to naturally push water back into the bore and return to its original static level.

04

Flow Performance Reporting

We compile the data into a clear performance report. We outline your bore’s maximum safe yield, recommend the ideal depth setting for your permanent submersible pump, and define the maximum daily run hours to prevent over-pumping.

Essential Questions Answered

A yield test measures the volume of water your bore can sustainably produce over time (usually measured in liters per minute). You need one to ensure you don’t install a pump that is too powerful for your aquifer, which can ruin the bore and burn out the pump motor.

Absolutely. Buying a property with an unverified bore is a massive gamble. A pre-purchase flow test tells you exactly whether the existing bore can support your household, livestock, and reticulation needs before you sign the contract.

For standard residential and hobby farm properties, a thorough flow and recovery test typically takes between 1 to 4 hours. For large commercial agricultural setups or licensed water entitlements, extended testing may be required to meet regulatory standards.

A slow recovery time means the surrounding rock fractures or sand strata take longer to recharge the bore casing after it has been pumped. If your recovery is slow, we will advise you to set up lower-volume, staggered pumping cycles to keep the system sustainable.
