Sanitary Sewer

Sanitary sewer collection systems are one of the most critical elements of a municipality’s infrastructure. Sanitary sewer systems are comprised of gravity sewer lines, lift stations, pumping stations, and force mains, and are used to convey domestic and industrial wastewater from its point of origin to a municipal wastewater treatment plant or a regional wastewater interceptor system. The availability of sanitary sewer service is essential for the stability and growth of a region’s economy.

Sanitary sewer infrastructure is expected to last for decades (20 to 50 years and more), despite the fact that it is exposed to extremely harsh conditions. Because of these harsh conditions, and the inevitable aging of our existing sanitary sewer facilities, there is now an increasing emphasis on development of asset management programs to ensure that sewer infrastructure continues to meet critical level of service goals.

Since its inception, Churchill has provided design and construction management services on wastewater infrastructure projects for new systems and facilities, extension of existing systems, and the maintenance, repair and replacement of existing facilities.

Although newer, more corrosion-resistant pipe materials, such as PVC and HDPE, have replaced older types of pipe commonly used in the past for sewer service, such as VCP, CIP and ACP, we have extensive experience with rehabilitating older types of pipe when practical, and with replacement projects where appropriate. Together with our ability to provide a full range of surveying, planning and permitting services, we offer extensive capabilities and experience in the following types of sanitary sewer projects:

I&I Studies and Sewer System Evaluation Surveys

Wastewater Management Plan Preparation

Feasibility Studies
