Fell , Assistan y ttorney ATTACHMENT 1 Proiect Description and Understanding Improvements to the existing South RO plant PLC and HMI systems are necessary to optimize automation of the plant operation . These include optimizing chemical feed system loops , alarms, and loop controls of major system components of the plant. This work will not only include improvements to the automation of the South RO plant operations , but will be used as a foundation for future integration of the water and wastewater control systems . This scope of work is identified as Phase I improvements to the overall utility systems integration of both water and wastewater plants . In anticipation of centralizing operations at the new Emergency Operations Center (EOC) , improvements to the control systems at the South RO plant is recommended as the first phase of integrating all water and wastewater treatment systems . Scope of Services See attached Exhibit A . Schedule The scope described above is anticipated to take approximately three months from notice to proceed . . Fees Consultant will provide these Services as described herein on a lump sum basis for $69 ,000 : The fees and services stated in this Agreement are valid until December 31 , 2004 .
