Testimonial
“Lakeside Excavation Inc. was awarded the Sanitary Sewer Improvements Phase Il bid for the City of Plentywood in June 2020. The work included renovating and replacing a large portion of the city’s sewer infrastructure, including mains, manholes, and a lift station, in strict accordance with DEQ specifications.
Lakeside performed the work on this project in a timely and professional manner. The work was well-staffed and supervised, and we look forward to working with Lakeside on future projects.”
