All septic system services provided by a design professional who holds credentials in Washington state as 1) a licensed on-site waste water treatment designer and 2) a certified on-site septic system inspector. Over the last 10 years I have personally evaluated thousands of test holes for septic systems, short and long plat subdivisions as well as soils evaluations for real estate professionals and speculators. If you are looking at purchasing land, it is important that you contact us to conduct a soils evaluation prior to writing your offer up. Purchases made site unseen or offers written as "contingent on passing" can ultimately result in septic systems costing tens of thousands of dollars on account of poor soil conditions. Due your due diligence first! Our low overhead will save you money. Since we are not installers and do only design work, there is nowhere for us to hide costs or pad bids. You get our best price up front every time. Be sure to follow us on google+ at https://www.google.com/+BwonsiteSepticDesignSpokane, we look forward to the opportunity to earn your business!!
