Outcome Metric

A year of clean water provided to a person.

To calculate impact, we estimate how many outcomes the nonprofit caused.

Data Source

Outcome data collected through visits to filters. All filters are visited 1 month, 3 months, 1 year and 5 years after installation. All data from visits is recorded. Clean water for Haiti tracks the adoption rate of the filters over time and shows any issues in production, education, and technician training.

Time Period of Data

Jan. 1, 2017, to Dec. 31, 2017

Ratings are based on data the nonprofit itself collects on its work. We use the most recent year with sufficient data. Typically, this data allows us to calculate direct changes in participants' lives, such as increased income.

Method for Attributing Outcomes

Clean Water for Haiti conjectures that 20 percent of clients would have gained access to clean water through other pathways in the absence of the intervention. We therefore attribute 80 percent of the increase in clean water access to the filter program.

To determine causation, we take the outcomes we observe and subtract an estimate of the outcomes that would have happened even without the program.


Data Source

Cost data reported by Clean Water for Haiti and data and assumptions about partner and beneficiary costs.

All monetary costs are counted, whether they are borne by a nonprofit service deliverer or by the nonprofit’s public and private partners.


Impact Statement

$3 provides clean water to a person for a year.

We calculate impact, defined as the change in outcomes attributable to a program divided by the cost to achieve those outcomes.


Benchmark for Rating

Impact ratings of water purification programs are based on the cost to provide clean water relative to the market cost that a person incurs to buy water in that country. Programs receive 5 stars if they provide water for less than 75% of the estimated market costs, and 4 stars if they do so for less than 125%. If a nonprofit reports impact but doesn't meet the benchmark for cost-effectiveness, it earns 3 stars.


The nonprofit's cost to provide clean water is less than 75% of the local costs.

Why We Could Be Wrong

We welcome your suggestions for improving our methodology. Our methodology section includes explanations of how we mitigate these issues.

  • The outcome could oversimplify total impact. Using “person-years of clean water” as the metric of analysis does not capture differences in the water quantity, reliability and ease of access.
  • There could be multiple important outcomes not captured in our analysis.
  • Clean Water for Haiti may be spending additional money in order to serve harder-to-reach and/or particularly valuable populations.
  • In the absence of better data, we assume uniform counterfactual rates for programs, at the risk of masking variation across nonprofits.
  • Our estimates rely on data made public by Clean Water for Haiti on its website, annual reports, financial statements and Form 990s.
  • We only analyze programs that meet our criteria. As a result, this report may not fully reflect the impact of Clean Water for Haiti .
  • We do not assess what explains the nonprofit's cost-effectiveness.

We assign a rating to the nonprofit using the rubric:

  • There are indications of governance or financial health issues at the nonprofit.

  • After being given an opportunity, the nonprofit chose not to publish impact information.

    We are not yet issuing this level of star rating.

  • The rated program does not meet our benchmark for cost-effectiveness.

  • The rated program is cost-effective.

  • The rated program is highly cost-effective.
