Step by Step Guide for Installing a Garden Pond

| |

A garden pond can provide many benefits for both homeowners and wildlife. It will add beauty and tranquillity to an exterior design while providing wildlife with homes, food, watering holes, and bathing spots.

It is the perfect water feature for creating an attractive focal point, and it will offer a sanctuary for various beautiful creatures, from fish and birds to toads and insects.

As autumn and winter are the perfect time to build a pond, there is no time like the present to get started. Read this step-by-step guide for installing a garden pond.

Step One: Pick the Best Pond Location

Before you start digging, find the perfect spot for the water feature. Ideally, position a pond in an area that will provide partial shade. If a pond experiences too much sunlight, algae growth may develop and cause a green hue that will pollute the water.

Despite requiring shade, you must ensure the pond isn’t directly underneath a tree. Otherwise, autumn leaves may fall into the pond water and sink, which will lead to debris accumulation on the pond floor.

Step Two: Confirm the Pond Depth

Once you have found the perfect location, you must confirm the desired pond depth. If your pond is for decoration purposes only, a minimum depth of 0.6 metres will suffice.

However, if you’re planning a pond for large fish or koi carp, it should have a depth of at least 1m to 1.5m. If you want to care for smaller fish, a depth between 0.6m to 1m is ideal.

Step Three: Plan the Pond Shape

Next, you’ll need to plan the pond shape for your garden. For example, you could choose:

  • A curved shape
  • Rectangle
  • Square

Bear in mind, the liner you choose can determine the size and shape while providing a water-tight barrier in the excavated hole. Therefore, it’s wise to add a flexible rubber liner to take control of the design.

Step Four: Dig the Pond

Once you’re happy to get started, you can dig your chosen perimeter with a shovel. Next, create a pond shape using string, sand or a spray marker and dig inward from the outside edge.

Next, remove the inner section of the soil. Once complete, mark the inner deep-water zone and excavate the soil to match your desired depth.

Step Five: Add the Pond Liner and Underlay

Once you have created the pond hole, add a pond liner. You can identify the correct measurements for the liner by using a flexible measuring tape to measure the area, starting from one end of the pond, and finishing on the far side.

Also, use a pond liner calculator to select the right liner. Before you have fitted it, you must add a protective underlay to create a long-lasting barrier.

Step Six: Find the Best Pump and Filter System

Create a healthy environment for any pond life by installing the right pond pump and filter system, which you can find the perfect option for your needs at

The pump will send water to the filter to remove algae growth, and it is then pumped back into the pond.

Step Seven: Fill the Pond

After you have followed the above advice, you must fill the bottom of the pond with a thin layer of sand.

Next, you can fill the pond with water from a hose, or you can allow it to build up naturally with collected rainwater. If you choose to use a hose, allow the water to settle for a few days before adding in freshwater life.
