"Our 38 year old home had water line leakage problems that were not only reflected on our water bill but with a "pooling" puddle near the house. Another plumber came out to make a repair visit and a follow-up "problem" visit a month later that still did not stop the problem. A month later when the problem arose for a third time we went on "Angi' seeking a replacement of the line. Robert of Coles Excavating contacted me along with a number of others. His personal conversations, both helpful and informative, impressed me; also his comparatively lower bid. Coles Excavating not only did a fine job replacing the water line, (I waited 30+ days before sending in this review) but Robert's continuing information and support as things progressed was greatly appreciated. My experience with Cole's, in a stressful situation, was truly an excellent one."

"Utilizing Angie's list to find Coles Excavating was extremely helpful to find a reliable and knowledgeable Contractor. I obtained 3 bids as recommended. Robert Cole answered all my questions and immediately made an appointment to look at our septic tank that needed to be replaced. He recommended a septic tank that was available at Home Depot and we were able to purchase using my military discount saving additional cost. Robert gave us a fair and competative price. He completed the installation and did a good job restoring the desert landscape. From beginning to end Robert communicated with us to ensure we knew each stage of the project. We can highly recommend Robert and his sons for excavation and septic tank installation."

FAQs for septic system installation and replacement projects in Tucson, AZ

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.
