Septic tank installation Cardiff: what to expect

We’ve simplified the process of installing a new septic system or replacing your existing one. Here are a few pointers that will pop-up when you choose Tankology as your installation company in Cardiff.

Getting to grips with your domestic or commercial needs

With any home or business septic system installation we will consult with you first. During this discussion process we will discern the type of new septic system suitable for your requirements. It’s not uncommon for us to visit to your home or business to conduct a few checks.

When understanding your needs we will look at at number of factors. Such factors include the potential population size for the property or the projected volume of sewage and wastewater.

Conducting a percolation test for your soakaway

All new septic systems disconnected from the mains water supply require a soakaway. As a result, if you haven’t done so already, you’ll need to conduct a ground percolation test. This vital test is completed in conjunction with a Groundwater Source Protection Zone search and Trial Site Assessment hole. We’ll take care of this if you haven’t done so.

Keeping disruption to a minimum

If we are replacing an existing septic system we’ll attempt to cap just before we install your replacement system. As a result, there should be minimal disruption to your household or business.

Fully compliant with drainage regulations

All new septic system installations need to either be connected to the mains, or have a wastewater soakaway or drainage field. There are also a number of other regulations implemented by the Environment Agency Wales.

Every sewage treatment tank we install will be fully compliant with all the latest off-mains drainage regulations.
