Stormwater pits and drains

Stormwater systems carry rainwater from roofs, paved areas and yards. Leaves, silt and debris can collect in pits and restrict flow. Our cleaning service removes that material and addresses blockages within the agreed scope. Describe which drains are affected and when you notice the problem.

When to arrange a clean

Water lingering around a grate, a pit filling with debris or repeated pooling after rain are reasons to have the drainage checked. Cleaning can help where buildup is the cause; damaged pipes, roots or drainage design problems may require other work. Let us know about previous blockages or repairs when calling.

Residential, commercial and strata bookings

We clean stormwater pits and drains at homes and managed sites. For car parks and shared areas, tell us who will provide access and whether the work needs to fit around traffic or business hours. Identify all affected pits when requesting the quote so we can discuss the full job.

Getting a quote

Call 0434 048 887 with your address, the type and size of the system, and a description of the problem. If you know when it was last cleaned, have that date handy. We will discuss access, agree on the work and confirm the price before starting.

Before the truck arrives

Tell us where the tank or pit is, how the truck can reach it, and whether there are gates, narrow driveways or other access limits. If you have system plans or previous service records, these can help us identify the right access point. Let us know about any other tanks or pits that need attention when you book.

Stormwater cleaning questions

How often should stormwater pits be cleaned?

The interval depends on the site, surrounding vegetation and how much debris collects. If the pits repeatedly fill or drainage slows after rain, discuss a maintenance booking based on those conditions.

Is stormwater the same as sewer?

No. Stormwater carries rainwater; sewer systems carry wastewater. If a wastewater pit is the problem, see our sewer pit cleaning service.

Can you help after a storm?

Call our 24/7 line with your suburb and a description of the pooling or blockage. We will discuss availability and what can be assessed on site.

Other tanks on your site

If the property also has an on-site wastewater system, we provide septic tank cleaning and AWTS desludging. Mention any separate cleaning jobs when booking.
