Stormwater pit too low. How to raise

[jbob4]

A couple of stormwater pits in the backyard was built too low. I want to raise them. Do I need council approval? Can we do it ourselves and how?

Welcome to the Bunnings Workshop community @jbob4. It's great to have you join us, and many thanks for your question about stormwater pits.

Would you be able to show our helpful members a picture of these pits or provide some additional information about them? That would allow us to give some relevant advice on your situation.

When you say that they were built too low, what exactly is the issue with them? An image would likely help illustrate this. Be aware that if you're going to raise or lower a pit, you need to maintain the fall on the connecting pipes. Depending on the setup, it might be as simple as digging the pit out of the ground whilst disconnecting the pipes, raising the soil level, re-installing the pit, and re-connecting the pipes.

You won't need Council permission unless these pits are owned by the council and on an easement on your property. However, before commencing work, you'll need to check whether you require the services of a qualified drainage expert in your area. In many locations around Australia, you're not allowed to D.I.Y. your own drainage.

Please let me know if you have any questions.

Thank you, I’ve added a picture. The put needs to be raised because the ground will need to be raised as well.

Many thanks for the image @jbob4. It looks like a pit riser that you place over the existing pit to change the height would work a treat. This would be a great solution because the existing pit can stay where it is.

If you see one of our helpful Special Orders team members at your local store and give them the dimension of your pit, they'll be able to contact Everhard and order a suitable riser for you.

Please let me know if you have further questions.
