1 WWTP Operator The poor cousin? Opportunities for Better Control Room Design Standards Certification Education & Training Publishing Conferences & Exhibits Speakers: David Lee MIChemE, CEng 2013 ISA Water / Wastewater and Automatic Controls Symposium August 6-8, 2013 Orlando, Florida, USA

2 Presenter David is a Chartered Chemical Engineer, originally from the United Kingdom 25+ years industrial experience in Engineering Automation Operations Management Human Factors Engineering ISA Senior Member; ChemPID Safety and Human Factors Chair; VP of local section; ISA standards committee member. Aug 6-8, 2013 Orlando, Florida, USA 2

3 Presentation Outline Current State Current Trends and Best Practice How does this apply to us? Summary Aug 6-8, 2013 Orlando, Florida, USA 3

4 Is this you? Aug 6-8, 2013 Orlando, Florida, USA 4

6 The WWTP Operator Traditionally seen as field position Rounds Sampling Analysis Permitting Adjustments Line-Ups Batch Operations Calibrations Now inside/outside Operator Control System Monitoring and Control Often Lone Worker Aug 6-8, 2013 Orlando, Florida, USA 6

7 The WWTP Operator Multiskilled Field Operator Console Operator Chemist Biologist Instrument Technician Gardener Wildlife Expert Environmental Guardian Rower Licensed Aug 6-8, 2013 Orlando, Florida, USA 7

8 The WWTP Control Room Evolved to Current State Remote Multi-functional Control Room Lab Electrical Switch room Chemical Storage Permit Center Change House Kitchen Break Room Aug 6-8, 2013 Orlando, Florida, USA 8

9 Best Practice Control Room Evolved to current state Remote Multi-functional Control Room Lab Electrical Switch room Chemical Storage Permit Center Change House Kitchen Break Room Designed Centralized Single Function Control Room Aug 6-8, 2013 Orlando, Florida, USA 9

10 Situation Awareness The focus of today s best practice control rooms is to create an environment that supports providing the control room operator with optimal situation awareness Detect Diagnose Respond Ensuring the operator stays in the loop Move from reactive to proactive operational stance Aug 6-8, 2013 Orlando, Florida, USA 10

11 Situation Awareness Question: How do we keep our WWTP operators in the loop? Is it necessary? (How long do they have to respond?) Take the control system with them? Flashing light/horn outside building? Transfer control? Aug 6-8, 2013 Orlando, Florida, USA 11

12 Trends To support this we see the following trends Human Centered Design Human Factors Engineering approach Adoption of industry standards: ISO (Control Room Design) ISA 18.2 (Alarm Management) EEMUA 191 (Alarm Management) ASM Guidelines (HMI Design) EEMUA 201 (HMI Design) ISA 101 (HMI Design) ISO 9241 (Ergonomic Design of workstations etc.) Aug 6-8, 2013 Orlando, Florida, USA 12

13 Trends Centralized Control Centers Integrated Control Suites Control Room Kitchen/Break Room Situation Room Restrooms Exercise Room Library Copier Room Training/Simulator Room Aug 6-8, 2013 Orlando, Florida, USA 13

14 Trends Improved Console Design Use of Large Screen Displays Improved Environment: Lighting Noise Temperature Humidity Cleanliness Traffic Improved HMI Display Design Alarm System Aug 6-8, 2013 Orlando, Florida, USA 14

15 Trends Increased awareness of fatigue mitigation Increased awareness of ergonomics Changes in staffing philosophies Increased awareness of training development and delivery Collaborative environment - communications Aug 6-8, 2013 Orlando, Florida, USA 15

16 CR Project Elements Aug 6-8, 2013 Orlando, Florida, USA 16

17 Does this apply to us? Principles are the same! Design based on task analysis (ISO ) Aug 6-8, 2013 Orlando, Florida, USA 17

18 ISO Ergonomic Design of Control Centres Part 1: Principles in the design of control centres Part 2: Principles in the arrangement of control suites Part 3: Control Room layout Part 4: Layout and dimensions of workstations Part 5: Displays and controls Part 6: Environmental requirements for control rooms Part 7: Principles for the evaluation of control centres Aug 6-8, 2013 Orlando, Florida, USA 18

19 Is this our future? Unlikely! But elements of this are applicable. Aug 6-8, 2013 Orlando, Florida, USA 19

20 Summary Most WWTP control rooms have evolved to their current state. Encourage formalized approach to control room design based on ISO Design for the operator not the technology. Design with Situation Awareness in mind. There is often little cost differential in building a bad control room compared to building a good one! Aug 6-8, 2013 Orlando, Florida, USA 20
