Appendix B Model water safety plans The following represent 'model' water safety plans for a range of technologies including community-managed point sources (boreholes, springs, dug wells and rainwater) and piped water supplies as well as mechanised boreholes connected to distribution systems and utility distribution systems. These are laid out in tables that provide the basis of the information required. This format, however, does not imply that this is how water safety plans must be developed. For some of the hazard events, the risk will vary with season. However, the same categories are used as in other water safety plans for consistency. The risk should be interpreted as an overall relative frequency of occurrence. It should also be noted that for some hazards (e.g. priming water) the risk refers to the probability of the hazard occurring if the practice is followed and should not be taken as an overall assessment of probability of using priming water of all handpumps. Model plans are presented, in table form, and are followed by information on verification for: • • • • • • •
boreholes fitted with handpumps; protected springs not connected to piped water supplies; dug wells; mechanised boreholes; rainwater collection no disinfection as standard; a utility distribution system; and a community managed distribution system.
