108 mgd to 132 or 214 mgd.
• Meetings continue with Niles, Park Ridge and Des
Plaines.
• Morton Grove and Glenview have also expressed
interest.
• The Northwest Water Commission has held
meetings with these same communities.
• Northwest Suburban Municipal Joint Action Water
Agency still expressing an interest.
Debt service is still the largest cost in the sewer fund with approximately $10M in debt service per year (down from $12M). This cost is from the long range sewer improvement program that was completed between 1990 and 2010 for a cost of approx $210M. The program has been very successful in mitigating sewer water from backing up into basements
143 miles of combined52 miles of relief16 miles of storm
Sewer rehabilitation, using the Cured-In-Place Pipe (CIPP) lining process is main emphasis of sewer capital improvement program at this time. Fund approx $500K / year to do this work on smaller diameter sewers which allows for the rehabilitation of approximately 1% of the combined sewer per year133 miles of small diameter pipe (<36”)23.6 miles (18%) lined since 1987Annual lining program now targets 1% (1.33 miles) per yearLined an average of 1.4 miles/year in last five years
In 2013 used $3.1M low interest low from IEPA to rehabilitate X miles of large diameter sewer mains and $ XXX from TIF funds to rehabilitate X miles of large dia sewer mains.Following this work, 2.5 miles has been rehabilitateWe already have a loan for 1.0 mile in 2014 (Central Park Ave and Main St).Working to apply for loans for remaining 1.5 miles (Greenleaf, Mulford, Cleveland).11 miles of large diameter pipe (36” to 72”)Plan to line an additional 2.5 miles by 2017 using state low interest loan funding
Most North Shore communities had extensive flood damage after the heavy rains in late April 2013. Evanston customers had comparatively little damage, and most of that was due to flooding in the North Shore Channel and the TARP system being full. Our relief sewers functioned as designed and kept the vast majority of customers from experiencing basement backups.Hydraulic study will begin with flow monitoring to determine how sewage flows between the combined and relief sewer systems. The data will be used to construct a sewer system hydraulic model, with the goal of addressing areas that experienced basement backups in April, as well as any bottlenecks in the system.20-year, $210 million projectDrastically reduced basement backups Some backups occurred in April 2013 because TARP was full and North Shore Channel was floodedSewer system hydraulic study planned for the next few years
Municipal separate storm sewer system (MS4)20-30 years oldLocated in proximity to the lake and North Shore ChannelNew initiatives under MS4 Program aimed at protecting water quality20-30 years oldLocated in proximity to the lake and North Shore ChannelNew initiatives under MS4 Program aimed at protecting water quality
Allocating funding to minimize the amount of storm water that goes into the combined system. In 2013 funded the porous pavement in the parking lanes on Davis Street. Will look for similar opportunities in future year projects or to extend the relief sewer onto streets with only combined sewers to mitigate street flooding.
Any good capital improvement program requires an ongoing maintenance plan to protect the investment. Maintenance is performed by in-house employees,Have a total of just under 15,000 sewer structures (drainage structures and inspection manholes).
The current pace of water main replacement is faster than most communities in the Chicago area, but at some point it will have to be accelerated further, as existing mains cannot be expected to last more than 100 years.The 30” feeder main is a critical source of water supply and fire flow for Northwestern and the downtown business district, as well as forming the major water supply loop for the entire community. At nearly 80 years old, this main has exceeded its useful life and is increasingly at risk for failure. It has experienced two shear breaks in the last five years, all of which had the potential to result in full blow-outs if they had not been caught early. 157 miles of pipe87 miles (55%) are over 80 years oldAt current rate, it will take 58 years to replace 80+ year-old mains30” feeder main is also 80 years old
Approx. 32.5 miles replaced since 1987Annual replacement program targets 1% (1.5 miles) per yearReplaced average of 1.6 miles/year in last 5 years
Plant Reliability Improvements: Upgrade chemical feed to eliminate single point of failure and eliminate bottlenecks to enable full 108 mgd to flow to and from the 12 East Plant filters.Finished Water Reservoir: Existing reservoir is 80 years old and constructed of non-air entrained concrete that has been damaged by years of exposure to freeze-thaw cycles. Two separate studies recommend replacement within 5 years.Intake Improvements: Replace 20-year-old mussel control system and add heating system to 48” intake.Master Meter & Chem Feed: Improve metering accuracy to Evanston/Skokie (increase revenue), reduce chemical usage (reduce costs)Meter Reading System: Improve reading accuracy, eliminate estimated bills, and allow customers to view their water usage 24/7.
Three criteria used to prioritize mains for replacement: maintenance problems (breaks/leaks), fire flow restrictions, age of the pipeLining is a less expensive alternative to open-cut replacement. We hope to do a demo project with a 24” main on Pitner in 2015.\Water main replacement program: $3.1 – $3.5 million/yearThree criteria used to prioritize mainsReplace 30” feeder main: $7.2 million in 2015-2016Water main lining may be a less expensive alternative
Proactive valve testing, maintenance, and replacement allows faster and more efficient shut-downs during water main breaks. This reduces water loss, reduces labor costs associated with shut-downs, and minimizes the number of customers affected by a shut-down.New leak detection equipment purchased in 2013. Proactive leak detection aims to water loss (and water production costs) and catch water main leaks when they are small (to minimize damage from main breaks). New system will allow for leak detection in more areas than just the streets being resurfaced.C3 Program – 2,800 permitted devices, up from 1,400 in 2008 when the program started.
Filter improvements and companion plant reliability impts project will us to take the West Plant out of service for critical structural repairs, or to be demolished or retrofitted to make way for improvements related to plant expansion for new wholesale customers.
Anticipate negotiating a cost of service-based agreement with Skokie and have it in place before the current agreement expires.Commission is currently meeting with other communities to potentially add them as members.

It’s not hydraulically possible to “wheel” much water through Skokie or the existing NWC transmission main, so a new dedicated transmission main would be required to serve these communities.Glenview and Morton Grove could be included on the transmission main.
The proposed transmission main route is from the intersection of Hartrey & Cleveland, south on Hartrey, through James Park and then south on Hartrey to Howard and west on Howard to the City limit. Estimated cost for Evanston’s portion of the transmission main is $3.4M.
Based on facility level plan, $65M to expand to 132 MGD and $264M to expand to 214 MGDDesign, permitting and construction of pipeline tunnel and water plant expansion is estimated to take 5 years to complete.
