Septic System Design Services in Clark County

A good design all starts with a careful site and soil evaluation. We perform perc testing so we can accurately size a drain field, and from there will choose between either a gravity septic system or an aerobic septic system. If your property needs a specialized septic drain field then that’s no problem, we design for the long term and consider any future plans or maintenance access that might crop up. Every project gets a property specific and bespoke plan, there are no cookie cutter solutions churned out here. Our service works with new builds, remodels, vacation cabins and even small commercial sites too. Because we don’t manufacture or sell any equipment ourselves, our designs stay unbiased and focused on the long term performance. You get transparent timelines, realistic budgets and a partner who protects your investment from start to finish.


Fast and Stress-Free Process

One of the things our customers appreciate is how fast we can get started and begin tackling the projects you assign us to do. Once you approve a bid, we can then prepare submittals and aim for permitting in as little as 14 days. That lightning fast turnaround keeps your build on schedule and reduces any costly delays. Good communication is at the heart of what we do. We take time to explain your options clearly, walk you through the costs, and make sure you feel comfortable with every decision along the way. If your site needs a more creative approach then our team draws on years of real world experience to find solutions that meet all of the regulations without stretching your budget.
