STC Tank Cleaners servicing a septic tank on a rural Hawkesbury property near Windsor in north-west Sydney

Septic tank cleaning in the Hawkesbury

We clean domestic and commercial septic tanks across the Hawkesbury. The service removes accumulated sludge and scum, includes a check of the visible tank condition and takes the waste away. Tell us the tank size, last pump-out date and any drainage problems so we can discuss the work required.

Check which system your property has

Your suburb alone does not tell us whether the property has a septic tank, an AWTS or a mains sewer connection. Check your system records if you have them. Our septic tank cleaning page explains pump-outs; for an aerated treatment unit, see AWTS cleaning and desludging.

Suburbs and booking coverage

Contact us about work in Windsor, Richmond, North Richmond, Wilberforce, Glossodia, Freemans Reach, Pitt Town, McGraths Hill, Vineyard and Kurrajong. We cover a 50km radius from Berkshire Park. Give us the property address so we can confirm coverage, access and the next available booking.

Planning access to the tank

For larger blocks, let us know how far the tank is from the access road and whether any gates need to be opened. Have the location of each tank ready when booking. Mention steep or narrow driveways, locked gates and any uncertainty about the tank location before the booking. System plans or past service records can help us identify the correct tank.

Other cleaning services available

Alongside septic pump-outs, we clean sewer pits, liftwells and pumping stations and stormwater drains. For food businesses, see grease trap cleaning. Mention each separate system when requesting a quote.

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.

Local booking questions

Can I book an urgent pump-out?

Our phone line is open 24/7. Describe the overflow, odour or drainage problem when you call and we will discuss the next available response. Arrival time depends on availability and access.

What if I do not know when the tank was last cleaned?

Tell us that when booking. Tank size, use and condition all matter when planning the next clean. Keep the new service record so you have a reliable starting date.

Is AWTS cleaning the same as routine servicing?

No. Desludging removes accumulated solids; routine servicing includes separate equipment checks and any required reports. Confirm those arrangements with your regular service provider.
