"I would give a higher rating if possible, my wife and I had our septic tank overflow and backup. Lucas came to our rescue immediately and found our septic lid was cracked, and the drain field was bad, he had the lid repaired same day and installed a clean out. That same weekend he came back and dug up our drainage field and installed a new one. The sense of urgency and understanding he had for us was unmatched. He didn’t even charge us extra for the emergency. Truly a great service!"

"We didn?t hire this company only because they focus on septic and therefore our issue wasn?t something they dealt with, but I appreciate their business practices. We reached out via a third party quote service and they immediately called us. Even once they figured out this wasn?t a payable job (we are on a sewer main), they took the time to explain what was likely going on with our issue and make some recommendations. That doesn?t happen much so I think that?s worth recognizing."

"My wife and I found out that the foundation underneath our home had settled and thus pulled our PVC pipes causing them to crack in numerous places. We basically needed our entire plumbing system under the house replaced.A friend referred Legend Plumbing & Septic to us and we could not have been more fortunate to work with them. Bret and Jesse were incredibly responsive and thorough in their initial inspection, describing what needed to be done, how long it would take, etc. They kept to deadlines and performed everything as planned. No hidden costs and no hidden delays. They even arranged for any sub-contract work that was needed. They handled everything with the permits and was very thorough and professional.Jesse and Bret were patient and helpful with any questions that we had and were transparent throughout the entire process. All of the workers that replaced our pipes we punctual, professional, and courteous.This was a major job that could have caused us so many headaches,but Legend Plumbing & Septic made it very stress free for us.We highly recommend Legend Plumbing & Septic for any of your plumbing needs, especially major plumbing issues!"

"The customer service was remarkable. While troubleshooting the problem of a bog in my back yard where the septic system was, Gerald assessed an unrelated problem with my water softener system. He reviewed the manual and then called the company and performed a diagnostic and repair!! At every step he was a thorough and patient teacher regarding everything he did. He even instructed me about other potential problems unrelated to my septic system and what to do if there was an emergency. Gerald went above and beyond what I expected."

FAQs for septic system installation and replacement projects in San Antonio, TX

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.
