Design & Installation
Expert construction of septic tanks & treatment plants

Why Us
the experts in waste water systems
We offer a quick easy and professional design and installation service with all the key features and guarantees you would expect at market-leading prices.
We visit to discuss the options available to you and carry out an initial site assessment. This will establish in broad terms the type of system you need and what additional site surveys and ground investigations are required.
We will then send you our FREE quotation and detailed scope of work, and if you would like to proceed we carry out the full survey of your property and perform the percolation test if required.
Design and mobilisation would normally take 3-4 weeks, and site works typically last 4-5 days.
On completion, we will register the system with SEPA and arrange your Building Warrant with the Council.
