Poor construction techniques are to blame for many leaking water structures, which in turn affects water availability. Key construction issues such as the making of concrete, correct construction of stone masonry, as well as the issue of pipes passing through water-bearing structures. This section focuses on concrete making. Proper techniques are often bypassed or shortened, which increases the risk of failure and reduces the life of the structures. This is especially true in many drought-prone areas that have dry climates and where water is at a premium, since it affects the essential curing process.
