Site Inspection

We provide a free site inspection where we meet with you on your site to discuss where your Aerated Wastewater System is best placed for yourself and the council.


We can do as much or like or as little as you need. From preparing plans, organising excavation, plumbing, electrician and quarterly maintenance or simply just supplying the tank.
