The gravity septic system is one of our most popular options - and with good reason. It’s a cost-effective solution that can be adapted to a wide range of septic management systems, and in our hands, you’ll never have to worry about your wastewater management again. 


Why Choose a Gravity Septic System?

As the name implies, a gravity septic system uses the natural force of gravity to transport wastewater from your property or land into the drain field. The benefit is that no traditional pumps or other such equipment is necessary. 


Highly specified and carefully designed doesn’t have to mean complex; often, the simplest solution is the most effective, and the fewer moving parts involved, the lower the maintenance requirement and the less chance of things going wrong.


For the majority of Clark County properties, a gravity septic solution fits the bill perfectly.

We understand the logistical nightmare this sort of work can cause for people, so we manage all the necessary paperwork and applications ourselves. Once you approve our design, we can sort permitting in as little as 14 days. 


With decades of experience and a team of highly qualified professionals who adhere to the rigorous standards laid out by Washington State, you can rest assured we’ll take care of everything.
