Table 2.

Outcome and impact indicators (all are site-level, except policy indicators, which are country-level). For each indicator, data availability (at both baseline and follow-up), data quality, and suggestions for revising the impact assessment framework are reported. On the basis of these recommendations and other inputs, WHO will publish a separate document detailing revised indicators and associated data collection guidance.

Code Indicator Data Format Availability (% of Sites) 5 Data Quality Category 6 Comments on Suggested Revisions
O Operational Outcomes
O1a Infrastructure change as a result of WSP 1 Y/N, description 95 Good A Retain
O1b Level of operations and management practices Score of 8–40 (score of 1–5 each) 93 Good
(1) Operational monitoring plan A Retain
(2) Compliance monitoring plan A Retain
(3) Consumer satisfaction monitoring D Exclude because redundant with W3b
(4) Standard operating procedures A Retain
(5) Emergency response plan A Retain
(6) Operator or caretaker training programs A Retain
(7) Consumer education programs D Exclude because redundant with I1c
(8) Equipment maintenance/calibration schedules C Reconsider including as addressing such maintenance schedules is not emphasized in the WSP process
F Financial Outcomes
F1a Operating costs per unit water 2 $/m3 72 Poor D Exclude to simplify; revenue to cost ratio will suffice
F1b Operating costs per population 2 $/pop 71 Poor D Exclude to simplify; revenue to cost ratio will suffice
F2a Revenue per population 2 $/pop 71 Poor D Exclude to simplify; revenue to cost ratio will suffice
F2b Revenue to cost ratio 2 % 66 Poor B Retain but provide a step-by-step calculation guide to avoid mistakes and standardize the definitions of operating costs and revenue
F3a Financial support as a direct result of WSP 1 Y/N, description 89 Good A Retain
F3b Funds from government for water supply $/description 59 Poor B Retain but combine with indicator F3a and provide more guidance to clarify indicator and to improve reliability of data
I Institutional Outcomes
I1a Internal water safety meetings 2 Number 92 Good A Retain
I1b External water safety meetings 2 Number 92 Good A Retain
I1c Consumer water safety trainings 2 Number 85 Good A Retain
I2a Understanding of system 3 Score of 5–25 19 Poor C Reconsider including due to lack of meaningful measurements (unless a more effective and systematic measurement approach can be designed)
I2b Understanding of hazards 3 Number 19 Poor C
E Equity Outcomes
E1a Equity 4 Score of 6–30 (score of 1–5 each) 88 Poor C Reconsider including due to widespread misinterpretation until explicit consideration of equity through the WSP process is widely promoted
(1) Participation
(2) Groups identified and documented
(3) Hazards/issues prioritized
(4) Improvements benefit equitably
(5) Monitoring data disaggregated
(6) Emergency response and communication programs reflect needs
W Water Supply Impact
W1a Continuity Hours/week 93 Good B Retain but consider refining guidance to avoid rough estimates of continuity
W1b Service coverage % 76 Good C Reconsider including as expanding service coverage is often not a core priority or key outcome of WSPs
W1c Pressure atm/bar/m 22 Poor C Reconsider including due to data quality concerns (variable measurement methods and tendency to provide rough estimates)
W1d Unaccounted-for Water (UFW) % 30 Good B Retain but revise guidance to better distinguish between UFW and non-revenue water (NRW)
W2a Microbial tests 2 Number 89 Good A Retain
W2b Microbial compliance 2 % 60 Good A Retain
W2c Turbidity tests 2 Number 87 Good A Retain
W2d Turbidity compliance 2 % 37 Good A Retain
W2e Disinfectant residual tests 2 Number 74 Good A Retain
W2f Disinfectant compliance 2 % 21 Good A Retain
W2g Other water quality parameter compliance 2 %, description 0 Poor B Retain but standardize list of parameters and formatting
W3a Consumer satisfaction surveys conducted Y/N 92 Good A Retain
W3b Consumers satisfied 2 % 10 Good B Retain but consider recommending a household survey where suppliers do not have standardized data
W3c Consumer complaint records kept Y/N 92 Good A Retain
W3d Number of consumer complaints 2 % 22 Poor B Retain but standardize reporting
H Health Impact
H1a Cases of diarrhea 2 Number 43 Poor B Retain but revise guidance to highlight/address common discrepancies between health center and WSP coverage areas
H1b Other water-related illnesses 2 Number 31 Poor B Retain but revise guidance to highlight/address common discrepancies between health center and WSP coverage areas and combine with indicator H1a
H1c Diarrheal incidence 2 % 5 Poor B Retain but change to primary household data collection rather than review of existing household data available
P Policy Outcomes
P1a Proactive water quality risk management approaches are/were included in formal water sector policies or regulations at time of follow-up assessment Y/N, description 92 Poor B Retain but provide a standardized definition of risk management
P1b Activity to develop or revise national drinking water quality standards has been undertaken Y/N, description 92 Poor D Exclude because difficult to obtain information in a standardized and meaningful way and link to WSP implementation
P2a Proactive water quality risk management approaches have been adopted by other water-sector stakeholders (e.g., NGOs, UNICEF) Y/N, description 83 Poor D Exclude because difficult to obtain information in a standardized and meaningful way
P2b Proactive water quality risk management approaches are promoted in national or sub-national programs Y/N, description 83 Poor C Reconsider including this indicator reflects drivers of WSPs as opposed to outcomes

1 Only asked at follow-up; 2 cumulative value over the 12-month period before data collection; 3 only asked if baseline data collection was prospective; 4 all elements refer to women and/or disadvantaged groups; 5 except for Policy Outcomes, where the unit is “% of countries”; 6 suggestions regarding each indicator fall into four categories: A. Retain without changes. Indicators are important and reliable data were easily collected; B. Retain but modify to standardize answers and avoid calculation mistakes. Indicators are important but were associated with data quality and/or availability challenges that can be easily overcome; C. Retention requires further consideration. Indicators were associated with significant data quality and/or availability challenges that may be difficult to overcome (except at higher capacity sites). If retained, modifications will be needed; D. Do not retain. Indicators are not core to the WSP process, are redundant and/or are not sufficiently important to warrant addressing data quality and/or availability challenges experienced.
