Septic tank replacement or repair?

As you are reading this article, you may be asking yourself if you should repair or merely replace your faulty septic tank. Below, you will find various factors to take into consideration that will help you make your decision.

We have made this list to help guide you through your options and our recommendations.


Costs of septic tanks

Septics tanks offer an ideal value for money solution when dealing with the wastewater from your property. However, the cost of the tank is not the only expenditure to take into account. Indeed, the installation cost, the maintenance cost and the size of soakaway required, will all have an impact on your end spend.

Lightweight, low profile tanks such as the Tricel Vento are easy to transport, manoeuvre and only require a small excavation for installation, which all saves you money.

Septic tanks require soakaways or drainage fields as part of the effluent treatment process. As such, this can be viewed as a hidden cost or constraint: you might not have the space available, or you might want to leave the area for a future extension, garage, etc.

In such cases, a small and compact wastewater treatment plant such as the Tricel Novo offers a more suitable solution, as they do not require any drainage field.


Desludging: why is it important to get your septic tank serviced regularly?

All sewage treatment systems require desludging as part of their maintenance. A good practice is to have your tank emptied once a year. It protects your soakaway system, protects the environment and of course helps your tank to function properly and at optimum levels of efficiency.

Septic tank emptying should be carried out by approved personnel only and as such require a waste disposal licence. Check on the Environment Agency website the register of waste carriers, brokers and dealers.

We also have further information about septic tank maintenance available, including yearly and quarterly maintenance, how to take care of your tank and the maintenance requirements of your soakaway.


Drainage failures

A septic tank not being regularly emptied can lead to issues with the drainage fields. Indeed, unlike a wastewater treatment plant where the wastewater gets treated inside the unit, a septic tank separates the waste into three distinct layers, the “scum,” the “separated wastewater,” and the “sludge.”

Only the separated wastewater should leave the tank, if the tank does not get emptied regularly, part of the scum or sludge can flow into your soakaway or drainage field and block the pipes. If this occurs, there are unfortunately no solutions or repairs available, except to replace the system.

2020 deadline for Septic Tank Upgrades in England and Wales

If your dwelling is located in England and Wales, you are required to ensure your septic tank is compliant with the Environment Agency’s General Binding Rules: small sewage discharge to surface water.

In place since January 2015, the new septic tank regulations deadline is fast approaching. Indeed, by 2020 all septic tank systems which discharge directly into a watercourse will be in breach of the General Binding Rules.

As the homeowner, you are responsible for the sewage treatment plant which is on site and the impact that it has on the local environment. Upgrades to your current septic tank or a septic tank replacement may be necessary to ensure you don’t face penalties.
