Everything You Need to Know About The Process

Water is an essential part of our lives. Be it for domestic work or industrial purposes, a regular and uninterrupted water supply is a necessity. But unfortunately, low rainfall and bad weather often cause a shortage of clean water for many households and businesses.

One solution to the water shortage problem: bore water drilling. It gives you direct access to the water under the earth’s surface. This water can be utilised for domestic and commercial purposes without depending on external factors for a clean water supply. Many estate owners and businessmen are nowadays opting for bore drilling in Sydney to get rid of their water woes.

Before you decide that drilling a borehole is the answer to all your problems, let’s look at some important things to remember about borehole water drilling.

Can You Drill a Borehole On Your Own?

The answer is no. Bore water drilling needs people with specialised skills and the latest cutting-edge machinery. It cannot be done without professional experts.

An individual without professional help will face many challenges in the drilling process. Only an experienced professional can help you overcome these challenges.

What are the Challenges in the Borehole Drilling Process?

To Drill Deep Into the Surface

The depth of a water borehole can be between 60 and 200 metres. And its diameter can vary between 110 and 150 millimetres. These measurements are impossible to achieve using domestic drilling tools. Specialist equipment is required to dig deep enough for a borehole.

Extracting the Groundwater Effectively

Once the digging is complete, the goal is to extract clean water from underneath the earth’s surface. Professional drilling companies will have a specialised water pump that can be used to extract water from the hard-to-reach depths. They will also conduct a laboratory testing process to determine if the water is safe to drink.

Site Survey Before the Drilling Process

Since bore water is extracted from deep underground, it may or may not be safe for drinking. Non-potable water, meaning unsafe drinking water, can still be used for activities like washing cars, watering lawns, etc. But the bore drilling cost cannot be justified if you cannot access potable water. A geological survey of the site can prevent such things from happening. Drilling companies have experts who visit the site to evaluate whether the location has any water and whether it can be safely extracted. This step prevents you from making wrong drilling decisions.

The 4 Steps in Bore Water Drilling

If you decide to go ahead with bore drilling in Sydney, hire a professional digging company. Here are a few steps to consider:

Step 1 – Site Consultation by A Hydrogeologist

Before the drilling process begins, you need to ensure the borehole dig will yield good results. For this, a hydrogeologist will evaluate the site to determine if the location has clean water underneath its surface. They use advanced scientific methods to get a clearer picture of the site. The hydrogeologist will provide recommendations for the best location to start digging that can yield the best results and the most suitable drilling methods to use. The site evaluation process also ensures that no drilling is done into natural hazards or any man-made infrastructure like cables, pipelines, etc.

Step 2 – Drilling and Construction

The next step is to start the drilling process for the borehole - as per the recommendations given by the hydrogeologist. Specialised equipment like drilling rigs is used to dig deep into the earth’s surface. The depth and diameter of the borehole are decided as per the client’s water requirement and the recommendations.

Once the borehole drilling is complete, the length and breadth of the newly made tube are lined with a casing made of steel or PVC or both materials. This gives additional support to the hole and protects it from any surface intrusions.

Step 3 – Water Pump Test

Next, a test pump is installed to gauge the yield of the borehole water correctly. Various experiments are conducted with different sets of variables to regulate the changes and the impact on the water level of the borehole.

The findings of the test pump tell you the impact the borehole will have on the water level and what are steps needed to regulate these changes. This determines what kind of pumping system will be installed.

The water test also lets you know the number of bacteria and contaminants present in the water, determining what kind of treatment the water needs to go through.

Step 4 – Installation of the Pumping and Pipe Work

The final phase in the bore water drilling process is to install the pumping system and the appropriate pipework to ensure continuous delivery of the bore water as intended.

What is the Average Bore Drilling Cost in Australia?

The borehole water drilling cost will vary from one property to another because the final price is determined by the depth of water found in a location. Typically, the bore drilling cost increases if the depth of the borehole increases. Considering all this, the average cost ranges between $2,500 and $5,000.

If you have a project for bore drilling in Sydney, get in touch with a professional drilling company. Experts will guide you through the process, ensuring you get the maximum yields from your digging process.
