Overview¶

Household Drinking Water Treatment and Safe Storage Systems (HWTS) comprise a cluster of innovative technologies that have come into existence since the 1990s. As a part of a class of social technologies to end poverty, these technologies have a number of powerful and appealing characteristics—they are simple, self-reliant, local, user-friendly and low-cost.
Proponents of HWTS systems point to the need for effective technologies for rural, sparsely populated areas and rapidly growing, unplanned, peri-urban areas, which are not well served by large centralized systems.
