Sanitary Sewer Rehabilitation

The City of Rembrandt was facing a compliance schedule issued by the Iowa Department of Natural Resources to reduce infiltration and inflow into their nearly 50-year-old sewer system. DGR Engineering assisted the City in planning and successfully obtained a grant for nearly 50% of the project cost.

After delays related to COVID-19, the project was bid and came in under budget. Manhole lids were raised to provide better access in some areas, and rehabilitation of the sewer system was completed to give another 50 years of life to the City’s much-needed infrastructure.
