Edgewater NW began as a consulting firm specializing in onsite sewage treatment (septic) system design.

 Our original motto is:

"Solutions for Difficult Sites." 

We have designed many septic systems for properties that had been turned down as impossible sites. We have two Registered Sanitarians (the new designation is: Registered Environmental Health Specialist) on staff providing technical as well as regulatory know-how to overcome your property's challenging conditions.

When purchasing real estate outside of sewered areas it is vital to do your due diligence investigations. One of the most important inspections is the septic system. We are trained and certified as


Septic System Inspectors. We are Oregon DEQ Septic Smart inspectors. We have done thousands of septic system evaluations / reports.


In addition to design / consulting we also provide monitoring and maintenance for septic systems. This includes operations and maintenance (O+M)  for existing systems, cleaning, flushing and jetting pressure laterals and screen vaults in sand filters, recirculating gravel and Advantex textile filters. We take influent / effluent samples for laboratory analysis and we interpret those reports for the owner so that they understand how the systems operate.

Maintenance is critical to all systems. For more info click here to go to the EPA website for SEPTIC SMART

We can take your project from concept to on-going maintenance including Variance applications and WPCF or Water Pollution Control Facility Permit application.

We are an Authorized Dealer and Service Provider for Advantex AX systems.
