The surface should be slightly sloped, to avoid stagnant waters. To prevent stones turning loose, spread an additional cement layer, mainly around the pump, so no infiltration fissures may appear. For an additional platform for the pump, an old tire may be used. Finally introduce the pump into the guide pipe.
If the spring is larger, it can be protected by an archover the spring eye (where the water first comes out). Instead of the ferro cement tank, build a cavern with stones or with bricks. Usually, an arched board is used, on which stones are arranged. With this mold, you move forward line by line along the board. When the stones of each segment have been arranged, a cement mortar is spread in the space between stones or bricks, to fix the arch or vault. Also, for areas of water scarcity, any unused overflow water can be captured and stored in a pond or tank with impermeable lining to be used for irrigation purposes as and when needed.

====Other considerations====
A fence should be constructed 10m above spring eye (where the water first comes out) and around the water collection area to keep out animals. A cut-off drain 10m above the spring eye will reduce possible contaminated runoff from reaching the spring eye. Planting trees near the spring will protect it even more, prevent erosion, and make it a more pleasant place to collect water.
A holding reservoir is not always necessary. It can be constructed if dry season flow rate is insufficient to meet peak demand from users, or it might be a wise investment with decreasing reliability of spring flows. Size of reservoir to be determined according to balance between constant inflow and peak outflow rates.
