Master Plumber's license # 224991. Bonded and insured. No sub-contractors are used at Mike Ingrilli Plumbing; all employees are full-time and work directly for Mike.

"Don’t ever use this company! First, they overcharge! And, they will not come back and fix something they installed that should be warranted. We used him several times and every time they had to go back and fix what they installed. They wanted to charge us for the work that they Installed incorrectly. We are still dealing with this issue a year later. Obviously, we stopped using Ingrilli and we are with a more professional, reliable, plumbing company. Save yourself the headache and stress because there are plenty of other, qualified plumbing companies out there to use and Mike Ingrilli is not one of them! He is very rude and unprofessional!"

"The remodeler I am working with had recommended Riverside and spoke very highly of their services... so I called for help with my 2 water heaters that were both not working. I am so appreciative of the quick response and the quick fix. I had questions too about how those were configured and everything was explained to me.

We are a company that values each customer the same. Big or small job we will give you a detailed estimate of the work you request to get done. We are a newer company that consists of a Master Electrician and a Master Plumber that have been in the industry a long time and pays attention to detail. We have done whole house remodels, new construction homes, and lots of service / repair work.

"Had them build a small bathroom out of an old closet. Paid half in June and not completed until September 15. No communication unless I initiated. Including the permit. Would show up maybe once a week, after I called them. Had scheduled carpeting for September 10th and asked and was told multiple times it would be done by September 1. Undependable and stressful! The original plan they sent was not compliant with code and would have had to be completely redone if I hadn?t made a change request. Builders should know building codes, or at least ask if unsure. Rediculous!"

FAQs for septic system installation and replacement projects in Milwaukee, WI

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.
