Did you know it rains about 150 times per year in Sydney? That’s almost every other day dumping water on our properties – which means installing a stormwater pit is something every residence might need to consider sooner or later. That’s especially the case if natural drainage is an issue at your place, so are you wondering about residential stormwater pit installation? It will be perfect as a collection point for all that excess water, so that it can be safely diverted away from your precious property. Care about your home’s landscape and foundation? It’s time to learn how a stormwater pit works and the ins and outs of stormwater pit installation. Let’s dive in:

Stormwater pit in backyard: What you need to know

In many, many cases, drainage pit installation is absolutely essential to serve as a holding tank for all of that excess rainwater. But what is a stormwater pit, exactly? Basically, it’s just a big container, typically made of plastic, concrete, or fibreglass, that is buried underground at a low point in your yard.

As for how it works, it’s quite simple but it’s also quite ingenious: when it rains, the water flows into the pit through grates at the top, which filter out the debris. The collected water is then directed away from your property through connected drainage pipes, which should ideally lead to a stormwater drain system or safe discharge area. Think of it like this: the pit ensures that excess water is stored for a while so it can be gradually released, eliminating the risk of flooding and water damage to your landscaping and foundation making it an effective Sydney drainage solution. The only question that remains now is: how to install stormwater pit components at your place? Let’s take another dive:

Tip: The flooding in your yard might not actually require a stormwater pit. It’s possible water isn’t flowing due to partially blocked stormwater drains, so a professional drain inspection is advised before proceeding.

How stormwater pits are installed

Ok, installing a stormwater pit may be very tricky, but we’re going to educate you, recognising that it requires a good understanding of drainage systems and some heavy manual work:

1. Site selection & planning

Choose the lowest point in your yard where water tends to accumulate when it’s really been raining. You’ll need to consider the pit’s size and the direction of the drainage pipes.

2. Excavation

Dig a hole larger than the size of your stormwater pit. This requires precise measurements and you’ll also need to factor in the stability of your pit.

3. Preparing the base

Next, lay a bed of compacted sand or gravel at the bottom of the hole – that will give it stability. Then level the pit.

4. Installing the pit

How to install plastic stormwater pit? Recognise that concrete, plastic, PVC and fibreglass are all viable options, but they all have their pros and cons. Plonk it into the hole, ensuring it sits exactly level.

5. Connecting drainage pipes

Attach PVC pipes to the pit’s outlets, ensuring they all lead towards the most appropriate discharge point. Beware: This step will require a good understanding of gradient and flow direction.

6. Backfilling & compaction

Fill around the pit with gravel and compact it to ensure stability and prevent shifting.

7. Installing the grate

Finish up by fitting the grate to the top of the pit. It should be precisely flush with ground level for safety and effectiveness.

8. Final landscaping

And now, really restore your home to its existing (or extra!) beauty by restoring the area around the pit. This may include paving, planting or turf laying.
