"Excellent! Marty and his partner definitely know septic systems and how to evaluate their functioning level. We were very pleased and impressed with their knowledge, work ethic and the time they spent carefully checking every part of our system and explaining what they found to us. I will definitely use them again and tell neighbors as well. Several folks in my neighborhood tried going with the lowest bids on septic issues and all three had major repercussions! It pays to hire high quality people."

"The job was well executed. Compliments to everyone at Speedy Septic. Hayden Buley was very quick to respond to my request for an estimate. I called several other septic system installers on listed on Angie's list who were either booked far into the future, or who did not respond to messages. Hayden made an appointment and came out to inspect the site as agreed and on time. He was very personable and professional. He set up a second meeting involving Mr. Rooter. He then provided an emailed cost estimate. One uncertainty in cost was whether the drain field needed to be replaced. This could not be determined until it was unearthed and inspected. Fortunately the drain field was still functioning well. A new distribution box was needed, and the drain field pipes were cleaned with the "Jetter" and all was well. The job took a little longer than planned due to bad weather. Our only winter snow and ice storms happened while the job was underway. We live on a fairly high hill and the snow and ice conditions were fairly bad, so I can't fault Speedy Septic for having the job take a little bit longer than planned. Then made sure that we had functioning toilets throughout most of the job, always when their work day was done. I'm happy to report that original cost estimate was very accurate. Compliments to all of the Speedy Septic and Mr. Rooter crew. They worked hard in some very cold and nasty weather to get the job done."

FAQs for septic system installation and replacement projects in Sherwood, OR

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.
