Obtaining health impact data for rural sanitation campaigns poses a number of methodological challenges. Here the authors describe the design of a village-level cluster-randomised trial in the state of Orissa, India to evaluate impact of an on-going rural sanitation campaign conducted under the umbrella of India’s Total Sanitation Campaign (TSC). They discuss a number of methodological problems encountered thus far in this study that may be typical for sanitation trials. Nevertheless, it is expected that the trial procedures will allow measuring the effectiveness of a typical rural sanitation campaign, with sufficient accuracy and validity.
