Septic Tank Installation

Before we carry out your new septic tank installation our team will carry out a full site assessment taking geology and ground conditions into consideration. Once we have determined the ideal location to install you septic tank we can begin.

Tank Selection

The first step is for you to select the right model and size of septic tank, based upon the likely wastewater output at your home. We supply the full range of Harlequin water treatment systems. This means you can rely on us to specify and supply the tank in the same way you will rely on our septic tank installation team to do their job

Professional Installation

Our expert septic tank installers are experienced in installing septic tanks responsibly and with minimal disruption to your property. We recently installed a Harlequin cap 6 mini water treatment plant installed for a new customer whose existing septic tank had stopped working. The customer was impressed by the whole job including  the speed of the install and the way we kept the site tidy and landscaped the garden before we left. No small feat when you considering the amount of work done!



Damaged Septic Tank

A damaged tank can be a real headache but there is really no need to worry. Should you have an unsolvable problem with your current septic tank - damage is one of the most common issues -  we can supply and install a new septic tank . Additionally, there is a good chance that  your buildings insurance policy will cover you. Of course insurance coverage will help offset the costs of the new septic tank installation
