Your One-Stop Solution to All Site Development Needs

Count on our 40 years of business experience in Mount Vernon, IL

Lomax Septic Systems wants to be your one stop shop for your site development needs.  Our goal is COMPLETE service and satisfaction, which includes septic tank installation and sales, excavation, site clearing, and mobile home transport. We manufacture our own unique, energy-efficient aeration septic tanks ourselves.  We built our business on the concept of getting it right the first time, and we are proud that we can do 90% of the work needed on new property sites ourselves.


Owners, Ken and Boston Lomax, are happy to take care of you and provide you with professional and friendly service.  With 40 years of experience in building relationships with customers, we look forward to helping with ALL your needs, not just septic tank, but driveways, utilities, sewer, water and other site development.
