Basins in the Program

Phase:  Investigate, Design

Neighborhood Associations: McLoughlin, Elyville, Two Rivers

The City contracted with Wallis Engineering to evaluate the Linn, McLoughlin, Newell, and Falls Basins (previously Basins 5 and 8) in December 2021. Wallis is managing the program with consultation from the City. 

Most of the McLoughlin Basin has been smoke tested and the mainlines surveyed via closed-circuit television (CCTV). More smoke testing and CCTV are still needed. Wallis and the City may also decide to do supplementary dye testing. 

This basin is one of three (the other two being the Falls and Newell Basins) that were created from the prior Basin 5. Flow monitoring equipment has been set up for this new basin to define pre-improvement base flows. One project (Linn Project 1) is currently being designed in this basin, and a second project (Linn Project 3) is being defined. Both projects are planned for construction during summer 2023. 

Additional construction projects in 2024 and beyond are anticipated, but no further projects are currently identified for this basin.

The City contracted with Wallis Engineering to evaluate the Linn, McLoughlin, Newell, and Falls Basins (previously Basins 5 and 8) in December 2021. Wallis is managing the program with consultation from the City. 

Smoke testing and CCTV surveying of mains is needed for the Falls Basin. Smoke testing is anticipated during the summer of 2023, and CCTV during the winter of 2023/2024. Wallis and the City may also decide to do supplementary dye testing. 

This basin is one of three (the other two being the Falls and Newell Basins) that were created from the prior Basin 5. Flow monitoring equipment has been set up for this new basin to define pre-improvement base flows. 

Projects in this basin are anticipated to be under construction during the summer and fall of 2024. At this time, no projects are identified.

Smoke testing and CCTV surveying of mains is complete in the Newell Basin. Wallis and the City may also decide to do supplementary dye testing.

Smoke testing and CCTV surveying of mains is complete in the Linn Basin. Wallis and the City may also decide to do supplementary dye testing. 

Linn Basin Project 1 will be under construction in Fall 2023. Linn Basin Project 2 is in design and Linn Basin Project 3 is still being defined.

Phase:  Construction, Design, Monitoring

Neighborhood Associations: Rivercrest, South End

The City contracted with Century West to evaluate the Rivercrest Basin (Basin 10) for I&I abatement in December 2020. AIMS Companies was contracted to collect Basin 10 CCTV data in November 2020, as the City’s CCTV data was not sufficient by itself for the City and Century West to evaluate the condition of the basin’s sanitary sewer. 

Based upon the data collected by AIMS and the City, Century West and the City developed a three-phase basin rehabilitation project. Phase 1 involved the lining of approximately half of the sewer mains and public laterals in the basin. Phase 2 included the replacement of deteriorated sewer mains near Eastfield Drive. Phase 3 is replacing the other half of the sewer mains using pipe bursting and open trench installation methods. 

Rivercrest Phases 1 and 2 have been constructed, and Rivercrest Phase 3 construction is mostly complete. 

The three phase Rivercrest project did not address sewer laterals to the building, as the City did not have a policy in place to rehabilitate private lateral portions until February 2023. The City plans to return to the Rivercrest Basin, with Rivercrest Phase 4 to rehabilitate sewer laterals in 2023 or 2024. 

Once all sewer laterals in the basin have been rehabilitated, work in this area will be complete, pending evaluation of program success.

The City contracted with Wallis Engineering to evaluate the Linn, McLoughlin, Newell, and Falls Basins (previously Basins 5 and 8) in December 2021. Wallis will evaluate the Warner Parrott Basin for infiltration if the program has funding remaining after work on the other basins. Regardless, Wallis will evaluate for inflow (storm system interconnections) and do any needed disconnections. 

Smoke testing and CCTV surveying of mains is needed for the Warner Parrott Basin. Wallis and the City may also decide to do supplementary dye testing. 

This basin is one of two (the other being the South End Basin) that were created from the prior Basin 12. Flow monitoring equipment has been set up for this new basin to define pre-improvement base flows. No projects are planned or scheduled yet.
