The results of Survey 1 in Uganda are summarised below.
| Functionality performance level | % pass |
| Basic – working (yes/no) | 55 |
| Snapshot – provides sufficient yield (10 L/min) | 34 |
| Functionality performance – sufficient yield and reliability (<30 days downtime in last year) |
23 |
| Functionality including water quality – passes WHO TTC and inorganic parameters | 18 |
The ‘Basic’ and ‘Snapshot’ assessments reflect the requirements of national survey assessments, whilst the more performance-focused definitions are more relevant to local or regional surveys looking to track the functionality of individual water points or programmes through time.
The results of the basic survey (55%) are lower than the National functionality of rural water supply (86%). The difference is likely to be due to our different sampling methodology, where we randomly sample from all boreholes equipped with a handpump. The more comprehensive assessments of functionality performance which include yield and reliability are considerably lower.
Water quality is generally considered a service issue rather than strictly water point functionality. A breakdown of district results is shown in Appendix 3.

Some HPB’s are shown to have Thermo-tolerant coliforms (TTC) in excess of the WHO drinking water standard. TTC’s are a bacterial indicator of sanitary quality of water. We used the strict WHO standard of a failure being any measured TTC in the water, rather than a risk based approach which would prioritise higher concentrations of TTCs.
A few other HPB’s are shown to have inorganic water quality parameters in excess of the WHO drinking water standards. Inorganic water quality parameters found to be in excess were: Manganese, Zinc, Aluminium, and Boron. With the exception of one HPB which failed on two parameters, HPB typically fail on a single inorganic parameter.
