Retention basins are among the most frequently implemented storm water management systems. They are used to collect surface runoff and to improve the…
Springs
When groundwater makes its way to the earth’s surface and emerges as small water holes or wet spots, this feature is referred to as a spring. The use…
Manual Pumping
Hand pumps are water-lifting devices that can be operated manually to withdraw water from surface water sources, groundwater sources and reservoirs,…
Mechanised Pumping
Mechanised pumps are water-lifting devices used to withdraw water from surface water sources, groundwater sources and reservoirs or to pump water…
Bottled Water
Sales and consumption of bottled water have skyrocketed in recent years. The global consumption of bottled water reached 230 billion litres in 2010…
Well Development & Rehabilitation
Well development of drilled wells is a part of normal well drilling procedure after the completion of the well and before the final disinfection. It…
Drilled Wells
Drilled wells can serve as a low-cost water supply for single households, for small rural communities and for more urban areas. The working principle…
Water Source Protection
The source of drinking water can be either surface water based (lakes, rivers and streams) or groundwater based (aquifers). Water is always found in…
Water Vendors
Water vendors are common in many parts of the world where water scarcity or lack of infrastructure limit access to drinking water, particularly in…
Water Purification
SODIS
When microbially polluted water is exposed to solar light in transparent PET bottles, bacteria, virus and some parasites are inactivated by the solar…
Biosand Filter
The biosand filter (BSF) is a simple household water treatment device, which is an innovation on traditional slow sand filters specifically designed…
Chlorination
Water disinfection by chlorination was massively introduced in the early twentieth century. It set off a technological revolution in water treatment…
Colloidal Silver Filter
Colloidal Silver Filters (CSF) are simple household water treatment devices based on a physical treatment, which does not require energy supply. CSFs…
Household Water Treatment and Safe Storage (HWTS)
Lack of improved access to safe drinking water together inadequate sanitation and hygiene are the overwhelming contributors to the 1.8 million annual…
Ceramic Candle Filter
Ceramic candle filters are simple devices made out of clay and used to filter drinking water in order to removes turbidity, suspended materials and…
Solar Pasteurisation
Contrary to belief, it is not necessary to boil certain water to make it safe to drink. Heating water to 65°C (149°F) for 6 minutes, or to a higher…
Water Quality Testing
In many parts of the world, water is not safe enough to drink. There are basic qualitative observations that quickly determine if water is not safe…
Safe Storage
The health implications of inadequate water and sanitation services include an estimated 4 billion cases of diarrhoea and 1.9 million deaths each…
