Septic Tank Replacement

The government in 2015 changed the law on the requirements of replacement septic tanks. This means that all septic tanks that discharge into the local watercourse must be replaced by sewage treatment plants on any domestic property. In order to protect your local environment by not polluting it with the waste from a septic tank.

Replacing your septic tank is important to avoid costly fines from the local authorities. Our team of engineers can supply and replace your septic tank for a brand new sewage treatment plant. Using leading brands such as Marsh Ensign & Tricel Novo you can be sure that the replacement septic tank you purchase will work perfectly for you. Contact us today and our team will be able to arrange a site visit and estimate.

The Benefits Of Replacing Your Septic Tank

There are many added benefits to replacing or upgrading your septic tank from a financial perspective to being much more environmentally friendly. Newer septic tank models are more efficient at processing waste and therefore will be more cost effective in the long run.


Replacing your septic tank with a newer model can mean being more environmentally friendly. If your septic tank is cracked leaking or causing issues with the land around it then it’s time for a replacement. Having waste and chemicals seep into the soil can be detrimental to the local environment. If your septic tank has become less manageable through issues occurring due to age, damage etc. then a newer, lower maintenance model will be perfect.
