The project used standard methods to assess the following definitions of functionality for a handpump borehole.

1. Basic — is the water point working (yes/no)

• Handpump physically working and proving some water at time of survey visit.

2. Snapshot — does the water point work and provide sufficient yield (10 L/min)

• Basic functionality assessment, plus:
• Yield assessed from standard 30 minute stroke test conducted at the handpump borehole. The water point was assessed to pass the functionality test if the yield provided in the final 3 minutes was >10 L/min.

3. Functionality performance — (provides sufficient and reliability,<30 days downtime in last year)

• Basic and Snapshot functionality assessment methods, plus:
• Water point user survey used to assess the number of breakdowns and repairs in the last year, and number of days of downtime. The handpump borehole was assessed to be of sufficient reliability if the total downtime is <30 days in the last year.
• If the waterpoint had not functioned in the past year it was classified as abandoned

4. Functionality including water quality (passes WHO inorganic parameters, and TTC)

• Basic, Snapshot and Functionality performance assessments, plus:
• Inorganic water sample analysis for major and minor ions — the water sample chemistry must meet WHO standards for inorganic parameters.
• Thermo-tolerant coliform (TTC) water sample analysis — the TTC concentrations must meet WHO standard (<1 TTC)
