The East Manawa neighborhood in Council Bluffs, Iowa, has a long history of infrastructure problems. The original sanitary sewers were constructed with very flat grades using cast iron pipes. The pipes have developed scaling and require heavy jetting on a regular basis to maintain proper operation and flow. The streets are located within a narrow right of way, without storm sewers. The area has extremely poor drainage and the streets are in terrible condition. The neighborhood is located adjacent to a lake, a tributary creek and the Missouri River. High groundwater and poor soil conditions are a large factor when addressing infrastructure improvements within this area. Also, there were numerous other utilities within the right of way adding to the challenge of reconstruction. Discover how vacuum sewers and porous asphalt became the answers to solving these many challenges effectively and efficiently. Learning Objectives: Evaluate various sanitary sewer collection system options. Design a vacuum sanitary sewer collection system.
