Septic System Installation
Serving the Vancouver WA Metro – Ridgefield – Battle Ground – Camas – Washougal

If you live in a rural area, you may rely on a septic system to deliver wastewater away from your home. Septic systems need to be properly designed and installed in order to provide you with the best results. The type of soil you have, the topography of your land, as well as other factors, are also considered.
Whether you need your septic system replaced or need a new one installed, you can count on Earthworks Excavating Services. We’re dedicated to providing quality excavating work for our customers in SW Washington. Our close relationship with the county health departments and local area designers takes the guesswork out of resolving your septic system problems.
System Replacement vs Installation: Which Do I Need?
Not sure whether you need a brand-new septic system installation or a replacement for your existing one? The answer depends on several factors.
If you’re building a new home or your property has never had a septic system, you’ll need a fresh installation (of course). On the other hand, if you already have a septic system that’s showing signs of failure (like persistent backups, foul odors, or saturated drain fields), it may be time for a replacement.
Our team will work with you to assess your land, soil conditions, and household needs to design a system that works perfectly for your property.
Septic System Replacement Services
Septic systems do not last forever and at some point need to be replaced. Septic system failures can show signs in a number of ways, including slow drains, backed-up drains, soggy areas in your yard, and strong odors.
We can diagnose the problem with your septic system to determine if a simple repair is necessary or if the septic system has reached the end of its useful life and needs to be replaced. With over 20 years of experience, we can navigate you through the process of designing, permitting, and installing your new septic system.
Types of Septic Systems
- Conventional Gravity Systems: The most common type, using gravity to move wastewater from your home to the tank and drain field. Ideal for properties with suitable soil and slope conditions.
- Pressure Distribution Systems: These systems use a pump to evenly distribute effluent throughout the drain field, making them a great option for challenging terrain or less-than-ideal soil conditions.
- Mound Systems: When soil depth or high water tables present challenges, mound systems elevate the drain field above the natural soil surface to ensure proper treatment.
- Advanced Treatment Systems: For properties with environmental restrictions or limited space, these systems provide enhanced wastewater treatment before it reaches the drain field.

FAQs
How long does it take to install a septic system?
Most installations take anywhere from a few days to a couple of weeks. The exact timeline varies and depends on the complexity of the project (including permitting requirements and site conditions).
We’ll provide you with a clear timeline after assessing your property and completing the design phase.
How long do septic systems typically last?
With proper maintenance, a well-installed septic system can last 25 to 30 years (or more).
Can I have a septic system installed on any property?
Not all properties are suitable for every type of septic system. Factors like soil composition, lot size, slope, and proximity to water sources all play a role. That’s why a thorough site evaluation is something we handle as part of our comprehensive installation services.
