Container-based sanitation (CBS) - in which wastes are captured in sealable containers that are then transported to treatment facilities - is an alternative sanitation option in urban areas where on-site sanitation and sewerage are infeasible. This paper presents the results of a pilot household CBS service in Cap Haitien, Haiti. We quantify the excreta generated weekly in a dense urban slum,(1...
Sewerage is a very large and important infrastructure in water industry. Because around 20% of the municipal pipe network is estimated to be significantly damaged it is of high priority to inspect, maintain , and repair public sewers. During the last years mobile robots have been developed to inspect but also to repair the pipes. To navigate through the hostile environment, they are generally o...
The paper addresses the navigation problem for an autonomous robot designed to inspect sewerage. The robot, which is about half size of the sewer diameter, must keep its orientation in the entirely dark sewerage. The only a priory information known is the geometrical shape of the sewer (cylindrical, etc). This implies a strong geometrical constraint on the environment the robot can expect. In t...
The sanitary sewerage connection rate becomes an important indicator of advanced cities. Following the construction of sanitary sewerages, the maintenance and management systems are required for keeping pipelines and facilities functioning well. These maintenance tasks often require sewer workers to enter the manholes and the pipelines, which are confined spaces short of natural ventilation and...
We studied the effect of storm water drained by the sewerage system and discharged into a river and a small reservoir, on the example of five catchments located within the boundaries of the city of Poznań (Poland). These catchments differed both in terms of their surface area and land use (single- and multi-family housing, industrial areas). The aim of the analyses was to explain to what extent...
