Using WIMS to Gain Reporting Efficiencies, Consistencies, and Improved Communication
Rippling Water (Basic) Note: This video template is optimized for Microsoft PowerPoint 2010. In PowerPoint 2007, video elements will play, but any content overlapping the video bars will be covered by the video when in slideshow mode. In PowerPoint 2003, video will not play, but the poster frame of the videos will remain in place as static images. The video: Plays automatically after each slide transition. Is 15 seconds long. Seamlessly loops for infinite playback. To add slides or change layout: To add a new slide, on the Home tab, in the Slides group, click the arrow under New Slide, then click under Motion Background Theme, then select the desired layout. To change the layout of an existing slide, on the Home tab, in the Slides group, click Layout, then select the desired layout. Other animated elements: Any animated element you insert will begin after the slide transition and the background video has started. Layouts with video effects: The “(Green) Title and Content” and “(Purple) Title and Content” layouts are creating by using a color overlay on the video. With the video selected, under Video Tools, on the Format tab, in the Adjust group, select Color and choose Teal, Accent Color 6 Light (third row, seventh option from left) or Periwinkle, Accent Color 5 Light (third row, sixth option from left).

Helix Water district

Helix Water District Just east of San Diego
Serve ~274,000 customers plus ~250,000 customers of surrounding districts 106 MGD conventional filtration plant with intermediate ozone Implemented WIMS for DDW and internal plant reporting beginning in 2014

successes

Successes Everyone has access to relevant data from different sources
Interfaces allow data from various sources to be automatically Critical SCADA data is now getting looked at and QC’d daily – errors found and fixed! No longer have to tape SCADA trends together or re-do reports each time new data is needed Opportunities for error and inconsistencies have been minimized Logic implemented to determine if regulatory triggers exceeded

Lessons learned
11
Lessons Learned Staff time required for implementation, training, and troubleshooting is significant Full utilization of the software could easily be a full time job Need a champion with knowledge in writing advanced Excel formulas, Boolean logic, and/or SQL who also understands the reporting process There is a difference between entry forms and reports! Graph Pac is limited in capability, so some things may need to stay in Excel
12
recommendations
13
Recommendations Make entry forms for data coming through an interface
Plan to have several training sessions spaced at least a few months apart Plan to have an as-needed contract to help get new items set up and/or train new users Import historical data Keep entry forms as similar to existing as possible to help minimize change Document, document, document and have several parties involved to help with knowledge transfer

Future plans

Future Plans Distribution system reporting is being developed to include: Calculation of runoff into storage account, Use of CSV interface to pull raw gauge height into WIMS, Production of reports for storage, usage, rainfall, and plant production Projection reporting Power use and cost data Dashboards for Executive Management and Board of Directors Add buttons to operator dashboard for access to documents such as regs and SOPs Incorporation of jar test data into WIMS
