The performance of small-scale pit latrine emptying technologies (SPLETs) (Bangladesh)

This study aimed to develop and test composite performance indicators and technical audit parameters for SPLETs, assess the influence of the operators’ skill levels on the emptying performance. In addition, the study assessed the level of user satisfaction on the performance of the SPLET’s in order to determine the level of improvements needed for these technologies in Faridpur, Bangladesh. An audit checklist, field surveys, transect walks and interviews were used to collect primary data. The results based on composite indicators (serviceability and reliability, operation and maintenance, enabling environment, operators’ skill levels, and health and safety) and an overall composite index, indicated poor performance. The ability of SPLETs to perform emptying services as designed was adjudged not satisfactory by the professionals/practitioners, operators, and customers. Additionally, it was revealed that SPLETs in Faridpur lacked an important safety equipment and that the skills of the operators handling the equipment were inadequate. Furthermore, the enforcement of sanitation by-laws for SPLETs’ performance was low. It was, therefore, concluded that the performance of SPLETs in Faridpur was in a critically poor condition and needed urgent actions for improvement.
