Proactive planning and environmental stewardship are keywords when describing the McGoodwin, Williams and Yates project for City Water and Light of Jonesboro. The city faced growing concern regarding the capacity of its wastewater collection and transmission system to handle anticipated growth to the northeast. Time was of the essence, since a new hospital was already being constructed in the growth area.
To analyze the current system capacity and determine needs for immediate and future improvements, MWY performed a comprehensive study utilizing data from multiple sources, including recent flow monitoring results, land-use projections, and census data. In addition, actual water billing data was geocoded into a GIS system to help determine actual per capita usage in the area.
The existing system included aging lift stations, and the initial expectation was to upsize the lift stations to accommodate future flows. However, MWY recommended a new gravity flow system which eliminates the lift stations, reducing energy costs by a projected half of a million dollars over the next 20 years
