In 1949 Paul Stein Sr. started manufacturing septic tanks in a small shop in east Allentown. The Lehigh Valley and surrounding counties were growing rapidly, and Mr. Stein’s vision anticipated the need for a modern solution for quality sewage disposal in these communities. Monarch’s new precast concrete septic tanks were the answer!
65 years later, our product line continues to grow as we incorporate the latest technologies and advances in our industry. We offer a variety of products and systems for both storm water and waste water treatment. Please visit the Products Section of our website for complete details.
As we celebrate our 65th Anniversary, we wish to thank our loyal customers, dedicated employees, valued associates and suppliers for making our success possible.
