The clean water service of PDAM Loa Janan Sub-district has not yet reached all villages, including Batuah Village, which has not yet received clean water services from the government. To meet the need for clean water for the people of Batuah Village, they use drilled well water, dug water that does not meet health standards because it contains heavy metals that are toxic (poisonous). This activity aims to meet the needs of clean water for the community in Batuah Village. Activities start from identifying the potential and quality of raw water sources which include physical, chemical and biological parameters, designing and manufacturing clean water treatment units as well as testing the quality of water products produced, socialization and training to partner groups on the process of operating clean water treatment technology and monitoring the sustainability of the water treatment process after being managed independently by the partner group.

Hot Water Treatment (HWT) provides adequate phytosanitary assurance that treated fruits and vegetables exported abroad are free from devastating quarantine pests. Two systems for HWT are currently available for commercial use namely the batch/jacuzzi and the continuous flow system depending on user requirements. Several protocols have been developed the world over and a few in Africa, but adoption has been lagging because of various factors chief among them lack of large scale validations of experiments to guide application at the commercial level. Mango, Bell pepper, avocado, and French beans play an important role in the livelihoods of people in Africa. However, their export is constrained by pests such as the invasive Oriental fruit fly, the false codling moth, and thrips. To circumvent this issue, disinfestation HWT protocols have been developed which seek to provide quarantine assurance to lucrative export markets. Hot Water Treatment technology has several advantages over other conventional phytosanitary treatments. It provides a triple function of cleaning, disinfesting, and disinfecting and is friendly to users, consumers of the treated commodities, and the environment. We discuss HWT in the context of its future and applicability in Africa. It is the future of postharvest treatments.
