Community Water Distribution System (CWDS)
Treats Myriad Sources
Disaster Relief Units
World Help Foundation (WHF) serves as a catalyst to focus attention upon the world problem of unsafe drinking water. WHF does this through public awareness, education, research, the placement of sustainable solutions, testing, publicizing results, and replication. We believe that a set of "turnkey solutions" can be developed to address the range of existing water problems. WHF calls upon vendors to provide these `pre-engineered' units and systems. This equipment is modular. This enables us to match unit and system components with site conditions.
We provide temporary solutions that are to be used while permanent systems are planned. We implement permanent solutions that solve the problems of access, extended distribution, filtration, purification, and are able to address the need for alternative power. WHF is most active in smaller villages, meeting needs in community service facilities and addressing the need for community access for drawing water for home use. We have responded to needs for safe water in urban fringe settings. We are developing our capacity to respond in larger villages with mini-municipal systems. We provide facility units and community systems directly and soon will be working with other implementing groups to maximize our attack on `dirty water death and disease'. Disability resulting from water-borne diseases must also be addressed and WHF is exploring the feasibility of partnering to meet this need.
We are increasing our working partnerships with agencies capable of addressing other issues that link to safe water and sanitation. One need is for community level income generation activities, the profits from which would either augment a local safe water tariff or would operate alone to cover the expenses of on-going maintenance of the permanent safe water and sanitation solutions.
A permanent drinking water tower system processes and provides safe water for up to 5,000 people daily, depending upon the productivity of the water source. It is a complete system that will work with surface water, well water or underground catchment tanks. It will clean water that is contaminated, and requires minimal maintenance. The configuration is adaptable, depending on needs.
The system removes at least 99.9% of all bacteria, germs, amoebas and spores from the water. With proper configuration, the system also removes salt, pesticides, chemicals and metals such as lead, manganese, and uranium.
`Basic' system consists of a pump (electric or with alternative power), and distribution tower.
`Full' system consist of the `Basic' system plus 1 or 2 high capacity pre-filters, high capacity ultraviolet lamps, activated carbon filtration, 1,000 gallon tank on a 12’ platform, and 7 spigots capable of 1 gallon/min each.
`Full-plus' system consists of a pre-system filter of laterite and activated carbon for removal of arsenic and other mineral contaminants. If this configuration is deployed, no activated carbon filters will be used because the activated carbon is put together with the laterite in the pre-system filter.
Solar array with battery back-up or generator is used for areas where there is no electricity.
Reverse Osmosis unit is used for brackish (salty) water.
Disaster Relief Units
Disaster Relief Units (DRUs) provide drinking water for a small village or shanty on the fringe of town after disaster strikes, and used until permanent solutions are in place. It is a complete system that will work with surface water or well water. Units are housed in easily movable containers that can be set up each day and stored in a secure area at night. The unit is adaptable and can be configured depending on needs. Three DRUs are usually engineered together with pre-filters into Disaster Relief Systems (DRSs).
The system removes at least 99.9% of all bacteria, germs, amoebas and spores from the water. It also removes salt, pesticides, chemicals and metals such as lead, manganese, and uranium.
DRSs consist of: a pump; 2 high capacity pre-filters; 3 portable DRU containers, each housing 4 ultraviolet purification systems. Each DRS thus contains 12 UV lamps, 8 activated carbon filters, and 12 spigots capable of 1 gallon/~4 liters per minute each.
