Awarding a contract for third Northern Ditch phaseThe Northern Ditch Interceptor Project is divided into three phases. MAC Construction & Excavating recently has been awarded the third project phase for $1,010,000 for the demolition of three pumping stations and other miscellaneous appurtenant work.

The project’s $5.4 million Phase I and $5.2 million Phase II were previously bid. Both of them are now substantially complete.

The Northern Ditch Interceptor is one of the MSD Amended Consent Decree’s Big Four projects. It will divert wet weather flow from the Morris Forman WQTC system to the Derek R. Guthrie WQTC system. The system will carry wet weather flow from the Highgate Springs area to prevent pumped sanitary sewer overflows during rain events.

Construction of Broad Run Interceptor to advanceThe Broad Run Interceptor Sewer Project—which is a component of the approved Cedar Creek Action Plan—is located in southeastern Jefferson County near Seatonville Road. Its completion will allow the elimination of two MSD small package treatment

plants—Chenoweth Hills and Lake of the Woods. The project also will allow future development to proceed in the area according to this approved action plan. Moreover, a considerable amount of existing sanitary flow will be diverted away from the Jeffersontown Water Quality Treatment Center (WQTC) to the Cedar Creek WQTC due to this project.

During the course of their January 10 meeting, MSD’s Board members approved retaining T and C Contracting to perform the Broad Run Interceptor Project for $2,327,500. It includes installing about 9,000 linear feet of 36-inch and 30-inch gravity sewers, 400 linear feet of 8-inch through 24-inch sewers and 38 manholes, as well as other miscellaneous appurtenant work. The gravity sewer line will begin at the terminus of the Billtown Road Force Main and transport flow to the Fairmount Road Pump Station.

This work was performed during the second phase of the Northern Ditch Interceptor Project.

Upcoming Events

The U.S. Army Corps of Engineers (USACE) constructed the Fourth Street and 34th Street flood pumping stations in the 1950s as part of Louisville’s flood control system. The former is located on the southeastern corner of Fourth and Main streets; the latter is situated just south of the flood control levee on 34th Street. Both also function as sanitary pumping facilities in nonflood conditions. Their operation is summarized in the Corps of Engineers’ Manual, which addresses three existing modes of operation:

Eliminating dry weather overflows

lSanitary Lift Mode - no floodinglPlant Idle Mode - minor floodinglFlood Pumping Mode - Ohio River flooding

The focus of USACE was protecting our community from flooding when it built the flood protection system. Conveying sanitary flows to the Ohio River was appropriate at that time because the Morris Forman Water Quality Treatment Center (WQTC) did not exist. The emphasis currently is being directed to reducing combined sewer overflows (CSOs) and eliminating unauthorized dry weather overflows (DWOs) from the combined sewer system to comply with the Clean Water Act and MSD’s Wet Weather Consent Decree.

Structural changes will allow MSD to maximize sanitary flow to Morris Forman WQTC to decrease sanitary flow to the river during wet weather and eliminate DWOs during dry weather operations. Two proposed construction projects will eliminate the Plant Idle Mode from both stations.

The Fourth Street Flood Pump Station DWO Elimination Project has been awarded to Advanced Paving & Construction Company for $773,780. It involves equipping three gates with hydraulic actuators and the associated hydraulic power unit for remote operation; replacing access hatches at two gates; installing a new access manhole for CSO 23; and installing six water level sensors to allow accurate flow measurement.

Additionally, Pace Contracting was awarded the 34th Street Flood Pump Station DWO Elimination Project for $397,000. Its scope includes replacing the existing actuator for one of the gates with a remote-controlled electric actuator; installing two hydrostatic level sensors downstream of Gate 71 and one upstream of CSO 19; and installing a small sump pump for returning trapped flow to the combined sewer system to eliminate DWO potential.

East Rockford Lane Pump Station will be relocated

MSD’s Integrated Overflow Abatement Plan identifies the East Rockford Lane Pump Station as a sanitary sewer overflow resulting from surface water flooding at the station. This pumping station will be upgraded. It will be moved as well to a site with

a higher elevation in order to diminish the effects of flooding. Both the existing and the proposed pumping stations are located just east of Dixie Highway in the vicinity of East Rockford Lane.

Kelsey Construction has been awarded the East Rockford Lane Pump Station Relocation Project for $366,650. The project entails installing about 174 linear feet of 8-inch sewer, 54 linear feet of 6-inch force main, one manhole and a pumping station, along with an emergency generator; decommissioning a pumping station; and other miscellaneous appurtenant work.

Customers FirstI appreciate the hard work of everyone

on the Snow Team to battle the snow

and ice during the last few weeks in

an aggressive, professional way. I have

heard throughout the city about how

clear our streets have been. It has

gone so well that there is a tendency

to take for granted what the Snow

Team crews do, but I know they are

out there at all hours dealing with all

kinds of situations. Keep up the good

work, and thanks for a job well done.

— Mayor Greg Fischer

MSD is lucky to have Claretta Hasberry and Leila Cunningham, who are nice, professional, helpful and

knowledgeable. My mother was all

upset when she called MSD about

a recent backup, but Claretta was able

to calm her down.

— John Mayhew

Thanks to Tony Kimbrough and

James Redd for the super job that

they did of responding to the backup

and resolving the problems.

— Chad Evans, Evans Property Management

Board ActionslPreviously, the members of the MSD Board endorsed the Thirteenth Supplemental Sewer and Drainage Revenue Bond Resolution, which authorized staff to refinance all or part of MSD’s 1997A, 1997B, 1998A and 1999 Revenue Bonds. All these bond issues have been refinanced, except for the 1998A Series. The Board in January approved the Sewer and Drainage Revenue Bond Sale Resolution, Series 2011A.

lOn January 24, MSD’s Board members approved the Subordinated Debt Resolution, which authorizes issuing 2011A Bond Anticipation Notes.

lMSD’s current AutoCAD package has become outdated in efficiently performing in-house engineering design and drafting. Recently, Board members endorsed the following: -- the purchase of 10 Dell Precision T3500 PCs; -- the upgrade of three existing AutoCAD licenses, and the purchase of four more licenses of AutoCAD Civil 3D software from DLT Solutions; and -- the purchase of training for 10 users from Advanced Solutions as part of the AutoCAD Upgrade and Implementation Project.

lIn January, MSD’s Board allocated $55,500 to procure stainless-steel impellers and wear rings from Straeffer Pump for enhancing the performance, durability and dependability of Northern Ditch Diversion Interceptor Project pumps.

lLast February, MSD executed a professional services agreement with CH2M HILL Engineering for such tasks as design support during construction and inspection services; development of—and approach for—systemwide optimization and control of MSD’s Real Time Control system; and SharePoint rollout and training for users. The MSD Board recently approved Amendment No. 2 with CH2M HILL, which raises the contract amount— by $710,305—to a new ceiling of $5,227,920.

lMSD has adopted a new five-year document printing services contract with OfficeWare for $130,000 per year.

lThe Board in July endorsed a standard professional/ technical services work order agreement for $250,000 with Heritage Engineering, LLC. In January, it allotted $60,800 for a contract amendment with Heritage Engineering.

lBoard members have approved the Johnsontown Sewer Assessment Report, and warrants will be issued to affected homeowners at an annual interest rate of 7 percent.

Cleaning upMSD’s Water Damage Cleanup Services contract provides for cleaning up sewer-backup or flood damage to residential or commercial property in our service area. This agreement requires more than one contractor because of the volume of work and the potential for multiple affected customers. MSD awarded the contract to three cleaning contractors in the past, but it has successfully worked in conjunction with two contractors during the last three years.

The Water Damage Cleanup Services contract has been awarded to Purvis Professional Cleaning as well as to Imperial Insurance Restoration and Remodeling at the same rate of service. The total estimated yearly expenditure is $280,000.

Updating green infrastructure action plans

Due to MSD’s commitment to Amended Consent Decree implementation, several Enviromental Protection Agency green infrastructure, Nine Minimum Controls (NMC) and Water Quality Treatment Center (WQTC) Action Plan

endeavors need to proceed. A consultant is required to design, standardize, build, monitor, validate and evaluate such green management practices as rain gardens, bioswales, pervious pavements and downspout disconnections throughout the Combined Sewer Overflow (CSO) 19 basin for eventually decreasing CSO volumes from this outfall and ascertaining the benefit to area water quality. The CSO basin also contributes to the Portland Wharf Storage Basin Project, which MSD’s Integrated Overflow Abatement Plan identifies for $20 million. Constructing green infrastructure in this basin will allow MSD to either downsize the basin or potentially eliminate the proposed gray project.

The project team will improve NMC by continuing to update the risk model associated with major industrial users in the CSO. The consultant additionally will update the Hite Creek and Floyds Fork WQTC action plans to include population, flow and available capacity projections, so that recommendations for optimization of existing facilities, permitting and facility expansion can be made for these WQTCs.

The Board has awarded a $1,477,665 contract to Strand Associates for accomplishing these objectives.

Green construction, such as this parking development in downtown Louisville Metro,will feature native plants in the new planting areas. This will not only look nice, but provide a way to reduce the volume of stormwater entering the combined sewer system.
