Design and construction phase
The Egis team provided design services for a 230-acre sewer separation project. The project included a network of new dedicated sanitary sewers, new sewer lateral connections to hundreds of homes and businesses, and a new storm sewer system, including a pond and pump station in an area frequently subjected to flooding during rain events. The pond area has helped to eliminate several vacant properties and add value to the surrounding neighborhood. The original contract scope included only the design of CSO 028; however, MSD’s trust in the Egis team led to the design of several additional design projects:
- White River siphon repair
- Cowan residential sewer
- Whitely stilling basin
- South burlington sanitary sewer
- Elgin and McGalliard stormwater pond
- CSO 027 design
- South Hoyt sewer system
- Additional services: Survey, right-of-way, public outreach and town hall meetings
