3.2 Roadside spring with inadequate collection reservoir, Sardinia, Italy

• To prevent sediment buildup, the minimum supply pipe gradient from the catchment to the spring chamber should be 3 percent. • It is recommended that an overflow pipe 5–10 centimeters higher than the supply pipe be installed.

Operation and Maintenance frequent maintenance of the spring area by a local caretaker and adequate operation by the community are necessary to ensure long-term usability of a spring (Bruni and Spuhler 2018).

The tasks of the caretaker should involve the following:

• Inspection, cleaning, and repair of spring installations (for example, cracks in the apron, leaking parts, and so forth) • Monitoring of activities in the surrounding area to avoid spring pollution • Upkeep of the protection zone and repair of the fence • Checking for appropriate operation by users
