Clean your stormwater pits and grates
Check all your stormwater grates, pits, and surface collection points. These can become easily neglected and forgotten over time. However you’ll want them all working for you when it starts to storm. For the most part, removing the grate lids and the pits, etc. can be done by hand. Just remember to wear appropriate gardening gloves.
Once you have cleared and cleaned out all your pits and surface drains, ensure the surrounding area is free from leaves and debris that could wash into the drains on the first downpours.
Run water down the pits with a garden hose to check for any blockages.
