"Ultimately happy with the end result and fair price for our 30ft sewer lateral replacement. Miguel was professional, friendly, and hardworking. However, communication was a bit spotty and we had follow up many times (I understand this is the busy season, though). Also, it was unclear if we were supposed to call 811; we assumed he would, but didn't, and this was an issue as the water line was hit during construction and the city had to come to shut it off on the whole street. It was handled quickly, but would have been avoidable. The project ended up taking much more time than expected, but it was completed in a day, as promised. I would recommend him, but you should be diligent and responsible yourself to make sure all the right steps are being taken."

FAQs for septic system installation and replacement projects in Novato, CA

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.
