"Initially I had a tank alert go off and called A-Advance Septics to pump my septic system and troubleshoot the alarm. The required services occurred over 2 days (12/1 & 12/3/2020). On 12/1, Matt V. was the service tech that came to locate/dig the tank lids. Matt was very professional in his work when pumping out the two tanks (septic and pump). Matt was very informative and helpful answering my questions, especially when I did not know about the pump tank plus the need to clean outlet baffle filter annually. Thus the need for replacement lid/risers for future access. Ray B. and Doug G. were also very professional and were able to troubleshoot the tank alarm issue and isolate to failed pump (26 years old) and need to be replaced along with new junction box. On 12/3, EJ M. and Doug G. returned to install 3 sets of lid/risers, junction box, and pump replacement. EJ and Doug were very professional in their work and were also informative upon answering my questions. Overall I was very satisfied on the work that was completed and definitely would recommend and call A-Advanced Septics for future service (I liked the feature on the new lids with your company name and phone number embossed, no need to jog my memory or scramble looking for company name or phone number). Thanks, Chester F."

"Iron Earth is the complete deal. They took down an 70 yr old garage that had seen much better days and replaced it with an exciting new garage and RV Port with a storage loft. Dan Faris and his crew did a marvelous job of tackling every step of the process; from planning, permitting, design, teardown, removal of old garage and every facet of the build. Unlike some contractors I've experienced in the past, he listened to our wants and needs. Discussing what could and couldn't be done while providing the details. I knew they were offering us to be partners in the process, not telling us what the project would be like others had. The team was professional and reliable i knew I could trust them in every facet. Iron Earth Construction and Dan Faris will be my go to for future projects, as I know I can rely on them. "

FAQs for septic system installation and replacement projects in Renton, WA

The smallest standard septic system uses a 500-gallon tank, which costs between $875 and $1,150 installed. This size works well for single-occupant dwellings with minimal wastewater production. However, many local regulations specify minimum tank sizes, so check with your building department before committing to this compact option. Some jurisdictions require at least 750 gallons regardless of home size to ensure adequate waste processing capacity.

The installation timeline varies based on site conditions, permit processing, and contractor schedules. The process includes obtaining permits, conducting soil tests, excavation, tank placement, leach field construction, and final connections. Weather conditions, soil challenges, and inspection scheduling can all affect the overall timeline. It's wise to begin planning well in advance of when you need the system operational.

The most economical approach is to install a conventional anaerobic system with a plastic tank. To minimize costs while maintaining legality, obtain multiple quotes from licensed installers, consider scheduling during their slower seasons, and handle basic site preparation yourself. Never skip permits or required testing to save money—illegal installations can result in significant fines and mandatory removal, ultimately costing far more than doing it right initially.

Regular pumping helps prevent system failures and extends operational life. Most small systems require pumping every three to five years, though frequency depends on household size and usage patterns. Pumping services cost between $290 and $530, making this maintenance expense relatively minor compared to potential repair costs ranging from $500 to $2,600 for neglected systems. Establishing a regular maintenance schedule based on your installer's recommendations helps avoid costly emergency services.
