Advanced Treatment Systems (ATT) & Sand Filters
When standard systems won't pass, advanced treatment and sand-filter systems make hard lots buildable — designed and installed to spec.
Not every lot in Central Oregon percolates well. High groundwater, shallow soil, or proximity to water can rule out a conventional system — but they don't have to stop your project.
We design and install advanced treatment (ATT) systems and sand filters that meet DEQ requirements on difficult sites, so you can build where a standard system can't go.
