A Partnership for Success
Presented by Jean-Francois Berard, P.Eng. AWWA Director, Quebec Section
16th Canadian National Conference on Drinking Water (Gatineau, Qc)
Overview
• Partnership for Safe Water – History – Objectives – Treatment Program – Distribution Program
• Program steps (Phases) • Canadian Participation
Partnership for Safe Water
• Program established by AWWA in 1995 to address Cryptosporidium concerns – Ref. Milwaukee outbreak, 1993
• Over 400,000 people affected • Over 100 deaths related to outbreak
Partnership for Safe Water
• Partnership for Safe Water mission: – To improve the quality of drinking water delivered
to customers of community water systems by optimizing operations.
• Two different programs: 1) Treatment plant optimization (1995) 2) Distribution system optimization (2011)
Current Partnership Subscribers • Treatment Program
– 233 Utilities – 433 Treatment plants
• Distribution Program – 145 Systems
• 40 States, DC, and Canada since 2013 (QC*, NS, ON)
• 50% serving population <100,000 (Smallest serve populations of less than 1000)
Partnership Treatment utilities serve a
combined population of more than
85 million
Partnership Distribution utilities serve a combined
population of more than 38 million
Partnership Optimization Philosophy
The Partnership for Safe Water achieves continuous improvement by optimizing operational performance. Optimization, as defined by the Partnership, means that all the system processes are being performed at the highest level (all the optimization goals of the Partnership are being continuously achieved). Self-assessment is a tool used to determine optimization status and to identify areas for improvement over time. Systems should engage in the self-assessment process to identify opportunities for improvement and to advance their optimization status. Participating utilities embrace the opportunity to discover areas for improvement. Only when these are known can they be improved. This is the outcome of the self-assessment.
It is difficult to achieve fully optimized status as defined by the performance goals of the Partnership for Safe Water. These goals reflect operational superiority. Optimization efforts are used to advance system operation to attain performance nearer the Partnership goals. Continuous improvement is a process. Partnership utilities tirelessly strive for higher levels of performance. Even the elite systems that achieve fully optimized status are never satisfied, so they continue to tenaciously search for ways to improve. The Partnership for Safe Water is a philosophy that embraces the quest for excellence in water system operation to improve the quality of water and reliability of service provided to all users.
Complacency
Complacency
Webster’s – “Self-Satisfaction especially when accompanied by unawareness of actual dangers or deficiencies.”
“Beyond Regulations”
• Partnership for Safe Water subscribers strive to set and meet performance targets that go beyond regulatory requirements. – Additional level of public health protection
Treatment Program • Open to surface water filtration
plants of all sizes and configurations – Focus on applying the
multiple barrier approach for turbidity reduction ≤0.1 NTU
– Optimize all unit processes for particulate removal
– Conventional, direct filtration, membrane, DAF, softening
Why 0.1 NTU?
• EPA – Composite Correction Program Handbook cites the results of pilot work indicating: – 0.1 NTU filter effluent turbidity indicative of
effective and consistent Cryptosporidium removal
• PSW self-assessment based on EPA comprehensive performance evaluation

*For chemically assisted filtration – membrane systems have lower regulatory turbidity levels and are also welcome to join the Partnership program
Distribution Program
• How do we help utilities improve water quality and protect public health after the water leaves the plant?
• Distribution system challenges: – Multiple uses, priorities – Out of sight – Water age, water quality
Distribution Program
• Open to any distribution system that applies a residual disinfectant – Disinfectant = chlorine, chloramine, chlorine
dioxide – Goal is to optimize distribution system
operations to ensure water quality and safety – Started in January 2011
Key Monitoring Parameters
• Disinfectant residual – Water quality integrity
• Main break frequency – Physical integrity
• Pressure management – Hydraulic integrity
2006 National Academy of Sciences report on Drinking Water Distribution Systems – Assessing
and Reducing Risks
Performance Goals
• Disinfectant Residual (>95% of meas.)* – Free Chlorine: ≥ 0.20 and ≤ 4.0 mg/L – Total Chlorine: ≥ 0.50 and ≤ 4.0 mg/L – Chlorine Dioxide: ≥ 0.20 and ≤ 0.80 mg/L
• No consecutive residual measurements outside target concentrations at optimized routine sample locations
• DBPs within regulatory requirements
Performance Goals
• Minimum Pressure (≥ 99.5% of meas.) – Pressure: ≥20 psi for daily minimum
• Maximum pressure (≥ 95% of meas.) – Does not exceed utility specified maximum
• Pressure fluctuations (≥ 95% of meas.) – Does not exceed range specified by utility
Performance Goals
• Main Breaks and Leaks – ≤ 15/100 miles of pipe/year - for reported
leaks and breaks in utility-controlled distribution and transmission piping
• Or – declining 5-year main break frequency trend demonstrating progress towards optimization
Getting Started
• Partnership relies on creating an engaged workforce! – Obtain support from management – Buy-in from all levels of the organization is
essential • Commit resources to the program effort • Participate in self-assessment process
– Work towards a common goal
Getting Started
• Does it take a lot of time? Personnel? Expense? – Data: plants already have – Self-paced process
• Many utilities meet on a weekly/monthly basis to “divide and conquer” self-assessment questions
– Focused on operational improvements rather than major capital expenditures
• issues identified using the self-assessment process can help utilities plan for future capital needs
Program Phases
• Phase I – Commitment • Phase II – Baseline data reporting • Phase III – Self-Assessment completion • Phase IV – Demonstrated optimization
Subscribers are required to comply with all applicable regulations, regardless of program Phase.
Phase I
• Submission of registration form and payment of subscription fee
• Commitment to participate in the program through Phase III – No time limit, self-paced
• DO NOT need to meet goals to join • DO need to be in compliance with regulations
Phase II
• Submission of baseline data 1) Treatment turbidity 2) Distribution disinfectant residual
• Why? To measure improvement over time.
Control parameters
Phase III – Self-Assessment: Objectives
1. Identify Performance Limiting Factors
2. Develop feasible action plans for improvement
3. Prioritize and begin work
Self-Assessment Process
• Self-Assessment of: – Performance – System design – System operation – Administration
Guidance documentation steps utilities through the Self-Assessment process
Action Plan Development • Utilities develop action plans for high
priority areas that are not optimized – Specific action – Assigned to appropriate team – Due date/target date based on prioritization – Results can be measured

After Completion • Monitor progress against plan
– Partnership for Safe Water annual reporting • Adjust action plan as needed • Submit annual data and narrative optimization
report to Partnership = accountability • Fully optimized systems can apply for Phase IV
Partnership for Safe Water status – Systems demonstrate commitment to maintaining
optimization and continuous improvement
