Symptoms:

• Having trouble controlling Settled Water Turbidity
• Monthly chemical bill increasing, over budget year to date
• Higher than historical backwash frequencies - loss of production
• Operators are changing dosing frequently based on gut feel. 
• No consensus on dosing strategy.
  

Plan:

Use WIMS to view Historic SCADA data from Hach Turbidity meters on Raw and Settled Water vs Alum usage entered manually by the Operators.

Savings achieved:

• 10% savings on chemical usage (~10K/yr per MGD)
• Better time management
• Consistent settled water turbidities requires less frequent backwash:
  Increased capacity
  Less wasted finished water

Management by exception:

• Dashboards allow easy monitoring for sustainability
• Notification by email or mobile devices for fast response to potential problems

Everyone is Making Data-Driven Decisions:

• Data clearly shows trends, issues and improvements
• Data provides visibility
• Data used to communicate more effectively
• Everyone knows what the goal is and how to achieve it
