Concrete is a valuable material for a number of reasons. For starters, it’s durable, visually pleasing and flexible. However, waiting for it to cure can increase downtime on-site. At Graham’s Precast Concrete Products, we pour concrete off-site for diverse applications on the Coffs Coast. We’ve got you covered for concrete septic tanks and septic tank installation.
Contact us or ring (02) 6632 2978 to organise a free, no-obligation quote. With four crane trucks at our disposal, your order will arrive promptly and ready-made for use. We ensure business continues to run as usual!
All our products are compliant with Australian Standards; we also hold certificates of accreditation by the NSW Department of Health.

Concrete Septic Tank Installation Requirements
At Graham’s Precast Concrete Products, we can deliver a concrete septic tank directly to your location on the Coffs Coast. But when it comes to installation, that is not a task we can complete on our own.
There are many different factors that must be taken care of for us to install your septic tank. To ensure a successful installation, a plumber and an excavation team must be present on the day. We cannot install your tank without both of these parties present and we do not organise these services for you—this is the client’s responsibility.

Frequently Asked Questions
How Often does a 5,00-litre septic tank need to be pumped?
This depends on the amount of people in your household. If the septic tank is used by two people, it should be pumped every five-to-six years. Otherwise, it’s recommended you organise a pumping service annually.
Are concrete septic tanks waterproof?
Yes! Unlike fibreglass and plastic options, concrete septic tanks are watertight. This makes them a popular choice among home and business owners looking for long-term wastewater solutions.
