Replace an aging metal septic tank with a plan you understand.
Concerned about an old steel tank, a deteriorating cover or visible corrosion? Talk with Dominick about the tank’s condition, access to your property and the work needed to replace it.
Replacement poly tank delivered for the Hurleyville installation.
Know what is underground
A working drain does not tell you the condition of the tank.
An older metal tank may still receive wastewater even when parts of its structure have deteriorated. Age, corrosion and the condition of the lid all matter when deciding what needs attention.
Start with an assessment of the existing tank and its connections. Replacing the tank is a different scope of work from replacing the entire septic system.
If the cover or ground looks unsafe
Keep clear of a suspected weak tank or lid.
Do not stand on a rusted cover or approach an area that is sinking. Keep children, pets and vehicles away and contact a septic professional. Never enter a septic tank.
Choosing the replacement
The right tank depends on the property.
Concrete and poly tanks have different handling and installation requirements. Access is an important consideration, but it should not be the only one.
Access
Can equipment reach the tank?
Fences, buildings, landscaping and narrow routes can affect delivery and placement. The plan should account for how the old tank will be removed and the replacement installed.
Site conditions
Will the tank suit the location?
Groundwater, soil conditions, burial depth and loading restrictions matter. A lighter tank still needs the right bedding, backfill and installation method.
System requirements
Does the proposed scope fit?
Tank capacity, connections, access openings and applicable requirements need to be considered together. The condition of the remaining system also affects the decision.

From a corroded metal tank to a replacement poly tank.
This Hurleyville project shows the old tank being uncovered, the replacement tank and piping, and the work area after backfilling. The close-up of the removed metal illustrates why the condition of an older tank deserves attention.

Understand the proposed work
A clear scope before excavation begins.
Tell Dominick where the tank is, what you know about it and whether you have inspection findings or system records. We’ll discuss access and the information needed to plan the work.
Discuss tank condition, inlet and outlet connections, property access and the remaining system.
Define the replacement scope
Confirm the proposed tank, excavation, pumping arrangements, removal, connection work and any required approvals.
Plan installation and access
Account for the manufacturer’s installation requirements, pipe elevations and future access for servicing.
Agree on completion details
Clarify connection checks, backfilling, cleanup and what restoration is included in the estimate.
Installation details matter
Follow the requirements for the tank being installed.
Our original project page includes the Roth certificate shown here. The important discussion for your project is the specific tank, its installation requirements and the warranty terms that apply to it.
Ask about bedding, backfill, site suitability and documentation before work begins. Warranty coverage should be confirmed for the selected product rather than assumed for every poly tank.

Common questions
Know what a tank replacement does—and what it does not.
A clear explanation helps you compare the proposed work and make an informed decision.
Does an old metal tank always need immediate replacement?
Condition matters, and age alone is not a complete assessment. Visible deterioration or a suspected weak cover deserves prompt professional attention. Keep clear of the area until it has been evaluated.
Can you replace the tank without replacing the drainfield?
Sometimes. A tank-only replacement depends on the condition and suitability of the rest of the system and applicable requirements. A new tank does not resolve an unrelated drainfield problem.
Is concrete always better than poly?
There is no single choice for every property. Access, site conditions, tank specifications and installation requirements influence the selection. We’ll discuss the options relevant to your project.
Will the inlet and outlet pipes be replaced too?
That depends on their condition and how they connect to the new tank. The estimate should explain what piping is included and how additional damage discovered during excavation would be handled.
How much does replacement cost?
Tank size and material, excavation depth, access, removal, piping and restoration affect the scope. Share your address and any inspection report so we can discuss the work needed for a meaningful estimate.
What happens to the lawn and landscaping?
Excavation creates disturbance. Before work starts, discuss equipment access, what will be protected, the cleanup included and whether grading, seed or other restoration is part of the estimate.
