UNITED WAY CAMPAIGN
CWL employees recently held their annual United Campaign and, once again, it was a huge success. Led by the CWL Employees Advisory and Safety Committee, the employees pledged $158,323.36 to the United Way 2017 campaign. There was 100% employee participation and 180 employees who pledged $500.00 or more a year. CWL employees truly are making a difference every day in their community!
CWL retirees continue to make a difference by donating $1,100.00 to the United Way Campaign! Thank You!
WATER SYSTEM HYDRAULIC MODEL
CWL has contracted SSR Engineers to assist us in constructing a hydraulic model of our water system. The model will allow us to simulate major fire flows and demands from new developments, which will help us to proactively and economically plan system improvements. SSR has completed the model and presented it to CWL in a meeting held on December 16, however the model will need to be calibrated. We have decided to postpone the flow tests needed for model calibration due to the hot and dry weather that we have been experiencing. The tests will be done once the weather gets milder and system water demands decrease. The model will be fully usable after this final calibration phase.
WASTEWATER – CAPACITY, MANAGEMENT, OPERATION, AND MAINTENANCE PROGRAM (CMOM)
CWL is expanding its efforts to maintain the highest quality wastewater collection system. This is being coordinated through the development of a Capacity, Management, Operation, and Maintenance program (CMOM). The CMOM team is currently working on reviewing a revised version of the program document.
The CMOM Program Software Committee made up of representatives from Wastewater, Engineering, Lab, Customer Service, IT, General Operations, and Administrative Services are reviewing several potential software solutions for managing the different attributes and data associated with the CMOM Program. The Committee has set a target date of December 31, 2016 for the selection of software.
SOUTHWEST DRIVE MOTOR-OPERATED VALVE
CWL is constructing a motor-operated valve facility just south of the Valley View Church of Christ on Southwest Drive. This valve will be normally closed and divide the 475’ and 530’ pressure planes. The valve facility will monitor the Craighead Forest Road Tank, which is the tank on the 475’ pressure plane in that area, and automatically open if needed to help maintain water levels in that tank. This will help provide more stable pressure in the area, as well as, provide a backup feed into the Valley View area. Foundation work is complete and the majority of the plumbing is also complete. Universal Builders has begun the building construction. The project has been rescheduled for completion by the end of September 2016.
CARAWAY ROAD TRANSMISSION AND DISTRIBUTION
Construction began July 18, 2016 on improvements of the 69 kV transmission line on Caraway Road from just south of Wilkins Avenue to just north of Phillips Drive. These improvements are a continuation of the Caraway Road upgrade to steel poles and will include some improvements to distribution design. The north section of this line, from the Caraway Substation on Primrose Street extending down Caraway to just south of Wilkins Avenue, was upgraded in 2015.
The line will consist of a 69V transmission line and a 13.2 kV distribution line. This will improve reliability in this area of the City. Project completion is scheduled for the end of October 2016, depending on weather conditions.
SOUTH JONESBORO DISTRIBUTION IMPROVEMENTS – PHASE I
Construction began August 4, 2016 on improvements to the 13.2 kV distribution system in south Jonesboro. These improvements include the construction of a new double 3-phase circuit from Caraway Road to Harrisburg Road across the north side of Jonesboro Memorial Park. It also includes the addition of a second 3-phase circuit on the existing Craighead Forest Road distribution line from Harrisburg Road to Forest Hill Road.
ELECTRIC / WATER PEAK
CWL reached a new all time electric peak of 303 MW on August 3, 2011 at 3:00 p.m. Our previous peak was 289 MW on August 3, 2010 at 3:00 p.m. Prior to the 2010 peak, we reached 277 MW on August 16, 2007 at 4:00 p.m. The electric peak for 2016 is 289 MW at 3:00 p.m. on July 22.
CWL established a new Winter Electric Peak of 254 MW on January 7, 2014 at 9:00 a.m., with a low temperature of 7º and a sub-zero wind chill. This surpasses the old peak of 233 MW set on January 12, 2011.
CWL reached an all time daily water peak of 29.26 million gallons on June 30, 2012. Our two previous peaks were 28.034 million gallons on June 19, 2010 and 25.279 million gallons on August 22, 2007. Our water peak for 2016 is 22.9 million gallons, which was set on July 12.
