Frequently Asked Questions
How do I know if my property needs a septic system?
Properties that are not connected to the town sewer usually need an on-site wastewater system like a septic tank. If your block is rural, on acreage, or in an area without mains sewer access, a septic system is often the right solution. We can assess your site, check existing infrastructure and talk through how the property is used. From there, we recommend a compliant system that suits your land, household size and long-term needs.
What is involved in installing a new septic tank?
Installation starts with a site assessment, and in many cases soil testing, to confirm the best system type and location. We then help you choose a suitable tank, such as concrete or plastic, based on capacity and site conditions. After approvals, we organise excavation, place the tank, connect pipework and ensure everything meets local regulations. Once installed, we explain how to look after the system properly so it runs reliably for years.
What should I do if my septic system is blocked or overflowing?
If you notice slow drains, gurgling, bad odours, pooled water, or overflow near the tank, contact us promptly. Blockages can create hygiene risks and may cause damage if left too long. We will inspect the system, locate the cause and clear or repair it using the right equipment. After fixing the issue, we can also advise on maintenance steps to reduce the chance of it happening again.
