Current Activities and Accomplishments

The Contractor remobilized in May 2016 in coordination with the county road department. The Contractor has completed the new 30” line in Daly Road and is currently working at MH26A, 26B, and 26C. Look Ahead The Contractor will complete the laterals on personal properties. Restoration will complete as needed with seeding forecasted to start in the fall. Issues There are no issues at this time.

This project will replace the severely deteriorated Sanitary Sewer #161. Approximately 4,500 feet of new sewer will be constructed from the Daly Road CSO Treatment facility east of the intersection of Daly Road and Compton Road where it will discharge into an existing 30-inch-diameter sewer. Area residents will be less impacted by surcharging and flooding that occurs during wet weather. This project was classified as a “Phase 1” Wet Weather Improvement Plan project because it has the ability to reduce the volume of sanitary flow discharged from old sewers during wet weather events. All work associated with this project will be substantially complete by the Consent Order Milestone date of December 31, 2016 (Attachment 1A – Final WWIP).

10141080 – Ludlow and Lafayette

10143220 – CSO 179 Sewer Separation

The Northside Upper Bundle includes two projects intended to reduce both combined sewer and sanitary sewer wet weather overflow events. Sanitary sewer surcharging and overflows occurring at SSO 645 and SSO 225A will be reduced through construction of 1,700 feet of new parallel sewer in the Clifton neighborhood. The new parallel sewer will enable more sanitary flow to be captured in lieu of discharging to surface waters. The bundle will reduce combined sewer overflows through construction of separate sanitary and storm water sewers in the area of CSO 179. These projects were classified under the “Phase 1” Wet Weather Improvement Plan because they provide MSD with the ability to eliminate existing overflows. All work associated with these bundle project will be substantially complete by the Consent Order Milestone date of December 31, 2018 (Attachment 1A – Final WWIP).

Current Activities and Accomplishments The three projects comprising this bundle include: CSO 194 Sewer Separation (10143920), CSO 195 Sewer Separation (10143960), and CSO 525 Sewer Separation (10143940). Substantial Completion was issued for the CSO 525 Sewer Separation Project on May 31, 2013.

Design task orders for the remaining scope of work had a Notice to Proceed June 1, 2016.

Look Ahead Revisions to the Design Documents reflecting the reduced scope to be completed in 2 months from Design Notice to Proceed. Right of Way requirements will need to be verified upon design completion.

Issues No Float remains for CSO 194 and 195. The West Fork Model submitted in January illustrates that the bundle has some additional work to be done to meet the Final WWIP overflow requirements.

The Westwood Northern Bundle is located along the western side of the Mill Creek Basin. The Mill Creek basin lies in the heart of Hamilton County stretching from the Ohio River to the northern Hamilton County border and from Reed Hartman Highway west to Colerain Avenue. The Mill Creek basin contains portions of 32 cities, villages, and townships including: the city of Cincinnati, Springfield Township, Colerain Township, Forest Park, Glendale, Wyoming, Springdale, Sharonville, Blue Ash, Amberley Village, Norwood, and others.

The Westwood Northern Bundle includes projects intended to improve the quality of the headwaters of West Fork Creek by separating the sanitary flows from storm water. Storm water inlets, ravines, driveway drains, and parking lot drains will be diverted from the combined sewer system. Separating the storm and sanitary flows will reduce the combined sewage overflow events that occur during wet weather. This bundle will address combined sewer overflows at CSOs 194, 195, and 525 by separating existing combined sewers and installing storm sewers as a separate system. All work associated with this project will be substantially complete by the Consent Order Milestone date of June 30, 2017 (Attachment 1A – Final WWIP). The Westwood Northern Bundle (WNB)’s current designs for these projects provide a higher level of control than required by the Final WWIP. To fully comply with the Final WWIP requirements for this bundle, smaller scaled project designs are needed to be constructed for Project 10143920 (CSO 194) and Project 10143940 (CSO 195), compared to the currently designed projects. Project 10143960 (CSO 525) is currently in full compliance with the Final WWIP and has reached Substantial Completion. As confirmed by the 2016 West Fork model, Project 10143923 CSO 194 and 10143962 CSO 525 additional separations would not be needed and has been dropped.

Negotiations for required Right of Way easements are anticipated to complete in March 2017. Issues: No issues at this time.

This project involves realigning and replacing approximately 300 feet of existing 24-inch combined sewer pipe and four associated manholes. The existing pipes are in such poor condition that they could collapse resulting in backup and creating water-in-basement issues. Of greater concern is the possibility that the pipe segment in close proximity to the residence could collapse and result in damage to the house. The work requires the abandonment of approximately 128 feet of sewer and the removal of three manholes and a special chamber. This project is located in Delhi Township.

MSDGC has been working closely with the Lower Price Hill community groups for many years to improve its relationship with the community by reducing odors from the Mill Creek Wastewater Treatment Plant. Odor control facilities have been installed at various odor sources to reduce and treat plant emissions. However, the odor control systems for the plant influent and headworks need improvements in order to continue to provide reliable odor control and improve the performance of the existing systems. This proposed project will replace existing chemical feed equipment for the headworks chemical scrubber and provide new ferrous chloride feed system bulk tanks, containment area, piping, valves and automation. This project will also provide a new pumping system and secondary feed point for improved odor control throughout the primary and secondary treatment process.

MSDGC has been working closely with the Lower Price Hill community groups for many years to improve its relationship with the community by reducing odors from the Mill Creek Wastewater Treatment Plant. Odor control facilities have been installed at various odor sources to reduce and treat plant emissions. However, the Septage Receiving Station building space, where the trucks deliver wastewater from commercial septage haulers, does not have an odor control system for the air in the truck bays. The existing odor control system only treats the air from the channels below ground in the building. This project will provide an odor control system to treat the odorous air from the truck bays. The recommended alternative calls for two new 9,000 ft³/min dry media units to treat 18,000 ft³/min of odorous air from the Septage Receiving Station truck bays. As part of this alternative, new ductwork will be installed in the Septage Receiving Station to convey airflow to the new dry media units.
