There are several types of systems that can be built to exact water from a '''spring'''. The most common is to build a spring box, but a lower cost and simpler in design alternative is the [http://www.lboro.ac.uk/well/resources/technical-briefs/34-protecting-springs.pdf protection of a spring with no box]. Protecting a spring without a box is cheaper than digging a well or borehole, but spring boxes are more useful as storage when demand is greater than the flow, to prevent contamination, and providing the spring with an easy way to flow into a pipe.

Often, in rural areas, central water filters are installed at the source, which supply water to several houses. Generally these are unprotected, and at unattended hours even pigs bathe in the sole source of drinkable water. Often springs have slow flow rates and so are not suitable for water pipe or network systems. At those places, it is wiser to protect the spring well and set up a manual pump. This keeps the water clean, and can increase the water supply. Once a spring is protected it is relatively easy to run pipes (if the flow is big enough) and create a tap, using gravity to power the flow if possible, from the spring closer to the community.
