Rainwater harvesting is an age old approach that is used to provide supplementary and sometimes primary water sources for households in Uganda. In rural Uganda today, rainwater harvesting is becoming more relevant in providing water for households as it provides a water source that is convenient. The Uganda Rainwater Harvesting Association (URWA) was formed in order to raise the profile of rainwater harvesting in Uganda and has done so through building the capacity of common interest groups in skills to provide rainwater harvesting facilities for their households.

This solution is based on the know-how of the local NGO Saint Gabriel, acting in Toamasina for more than 10 years. Saint Gabriel aims at developping local basic sanitation and acces to drinkable water for all. It promotes construction of dry toilets, both as private and public infrastructures, and leads sensibilization action towards the population. Saint Gabriel also leads experimentation on compost methods, promotes the construction of “Key Hole Kitchen Garden” and aims at creating incomes-generating activities.

Government of Cebu province has used a set of standard designs for construction of public schools. Unfortunately, the current architectural designs don’t reflect eco-efficient perspectives and technologies in the construction of public schools such as rainwater harvesting and reuse, energy saving measures by cooling roof, wind ventilation for energy saving, wastewater treatment and reuse, and waste  management.

This year CAEM completed the construction of the West Metepec interceptor, a facility of 1.52 cm wide Ø 4500 linear metres pipe, from the intersection of H. Enriquez Street and the Jaras Canal to the mines area of San Miguel Totocuitlapilco. This project was divided into three stages: the first with a diversion structure to divert storm water into the interceptor, controlling waste and other solids from entering; the second with the interceptor already in use; and thirdly, a buffer structure, a regulating reservoir and a structure that allows for the maximum rainwater use.

Innovative solar disinfection for low-cost and socially acceptable potable water supplies from rooftop harvested rainwater

Rainwater harvesting (RWH) is gaining interest as a safe drinking water supply option to achieve Millennium Development Goals (MDG) in developing countries. The lack of scientific and engineering knowledge, such as uncertainty of microbial quality, unavailability of proper end of point treatment in developing countries, however, often prohibit the use of rainwater. Although simple Solar Disinfection (SODIS) by using a polyethylene terephthalate (PET) bottle was recommended by the World Health Organization (WHO), there is a limitation of this technology due to incomplete disinfection at moderate and weak weather conditions.

Space technology in the form of remote sensing can play a useful role in hydrological studies. Remote sensing is defined as the science of deriving information from measurements made at a distance from the object without the sensor actually coming in contact with it. Remote sensing though is a fledging phenomenon; seem to a shot in arm by either substituting or complementing or supplementing the conventional technology with reasonably faster, efficient and accurate methods of survey in the domain of water resource planning, conservation, development, management and utilization (Roy and Bhattacharya 1982).

This solution enables you to transport 15 water storage tanks that can store 21,000 liters of water on the back of a motorcycle. The product has the convenience of being right outside your home, is low cost, and has a tap just like piped water supplies.   EnterpriseWorks/VITA (EWV) is in the second year of a commercial pilot in Uganda introducing an award winning rain water storage solution called bob™.  Bob is a flexible container that is a bag in a bag; the outer bag provides strength and the inner bag impermeability. Bob folds up into a packet the size of a briefcase yet when filled holds 1400 liters of rainwater and retails for only about twice the price of a 200-liter plastic barrel but provides seven times the water storage capacity.

Since January 2009, Sarar Transformación has been providing improved access to safe water and sustainable sanitation to approximately 2000 students and teachers in 17 pre-school, primary and secondary schools in the upper Copalita watershed, Oaxaca, Mexico.  Drawing from its extensive experience with the SARAR participatory education methodology -and the related PHAST approach-, the program involves the entire school community in the assessment process, choice of technical options, and trains students, teachers and parents in the use and maintenanceof the facilities, as well as proper hygiene. Through such training, Sarar-T has introduced and fostered the uptake of alternative dry sanitation facilities, a previously uncommon technology in schools of the region, which conserve water and keep waste out of waterways.
