Septic Tank Changes

DASA provides septic tank replacement and conversion services for homeowners with damaged, failing or unsuitable wastewater systems. Our septic tank services cover assessment, repairs and replacement, helping you find the right solution for your property.

With over 40 years of drainage experience and nationwide coverage, our engineers can assess your existing system and explain the work required.

Septic Tank Replacement and Conversion

A failing septic tank does not always need replacing. Some problems can be resolved through septic tank repairs, while more extensive damage may make replacement the better option. Identifying the cause first helps avoid unnecessary work.

Replacement involves installing a new tank and connecting it to the property’s drainage system. The work required will reflect the condition of the existing tank, the drainage layout and access for excavation.

A conversion changes how the existing system treats wastewater. This may involve upgrading to a sewage treatment plant where suitable for the property. The right approach will reflect the system’s condition, wastewater volumes, ground conditions and discharge arrangements.

DASA can explain the available options and help you understand the proposed work before you decide how to proceed.

 

Planning the right system for your property

Before arranging replacement or conversion work, a septic tank inspection can help establish the condition of the tank and identify problems with connected pipework or the drainage field.

Our engineers can assess factors that affect the proposed system, including:

  • The number of people using the property.
  • The space available for the tank and drainage field.
  • Ground conditions and signs of poor drainage.
  • Access for installation equipment and future servicing.
  • The existing wastewater discharge route.

These checks help establish whether replacing the tank alone will address the problem or whether other parts of the system also need attention. Planning the work around the whole system helps reduce the risk of recurring drainage problems.

FAQs

How do I know if my septic tank needs changing?

Common signs include frequent backups, foul odors, slow drains, soggy areas in your yard, or your tank no longer meeting environmental regulations. A professional inspection can determine whether a replacement or conversion is the best solution for your property.

What is the difference between a septic tank replacement and a conversion?

A replacement involves removing the old septic tank and installing a new one of similar type. A conversion typically upgrades your system to a more modern, efficient, or eco-friendly treatment solution, such as a packaged treatment plant. Conversions can also help bring older systems into compliance with current environmental standards.

How long does a septic tank replacement or conversion take?

Timeframes vary depending on the condition of the existing system, site accessibility, and the chosen solution. In general, most replacements or conversions take between 3 to 7 days. DASA will provide a clear project timeline and handle all work with minimal disruption to your property.

How much does replacement or conversion cost?

Costs vary according to the system required, tank size, ground conditions and access for excavation. Changes to connected pipework or the drainage field can also affect the price. DASA can assess your property and provide a quote for the recommended work.

Will a new system still need regular maintenance?

Yes. A replacement tank or upgraded treatment system still needs servicing to keep it working correctly. The maintenance schedule will reflect the system type, manufacturer’s guidance and household usage. Sewage treatment plants may also require checks of mechanical and electrical components.
