The solution was to add UV light absorbers to the plastic of future vessels. In Madagascar , the project expanded from the city into a rural region affected by a cyclone. The only water source was a river with very turbid water. The dose of disinfectant recommended for clear piped water in the city was inadequate for the river water in the rural project. The solution was to double the dose.
Monitoring requires ongoing data collection during project implementation.
Evaluation requires data collection before and after a given period of project implementation. To plan for monitoring and evaluation, specify the information that will be needed, how it will be used for decision making and how progress and impact will be measured. Plans for monitoring and evaluation should be developed at the same time and integrated with plans for the whole project. At the beginning of the planning process, decide how monitoring and evaluation data will be acted on. Ensure that each piece of data collected has a purpose so that monitoring and evaluation is a meaningful practice that advances the project's goals and objectives.
