Dams are typically located at a narrow part of a downstream of a natural basin. The valley sides act as natural walls, with the dam located at the narrowest practical point to provide strength and the lowest cost of construction. In many reservoir construction projects, people have to be moved and re-housed, historical artifacts moved or rare environments relocated. Examples include the temples of Abu Simbel [2] (which were moved before the construction of the Aswan Dam to create Lake Nasser from the Nile in Egypt), the relocation of the village of Capel Celyn during the construction of Llyn Celyn, [3] and the relocation of Borgo San Pietro of Petrella Salto during the construction of Lake Salto. [ citation needed]Owners and undertakers must keep plans under review and test them as advised by a reservoir panel engineer. Two main types of reservoirs can be distinguished based on their mode of supply. [17] Reservoir Type The incoming tenant must enter into a Tenancy Agreement with us and pay sums due within this agreement. People have been creating reservoirs for thou sands of years. The oldest known dam in the world is the Jawa Dam in what is now Jordan. It was built in about 3000 B.C.E. to store water to use for irrigation, or watering crops.

non-impounding reservoirs panel for supervising engineers for any reservoir and inspecting or construction engineers for non-impounding reservoirsWhere water is pumped or siphoned from a river of variable quality or size, bank-side reservoirs may be built to store the water. Such reservoirs are usually formed partly by excavation and partly by building a complete encircling bund or embankment, which may exceed 6km (4 miles) in circumference. [10] Both the floor of the reservoir and the bund must have an impermeable lining or core: initially these were often made of puddled clay, but this has generally been superseded by the modern use of rolled clay. The water stored in such reservoirs may stay there for several months, during which time normal biological processes may substantially reduce many contaminants and reduce turbidity. The use of bank-side reservoirs also allows water abstraction to be stopped for some time, for instance when the river is unacceptably polluted or when flow conditions are very low due to drought. The London water supply system exhibits one example of the use of bank-side storage: here water is taken from the River Thames and River Lee into several large Thames-side reservoirs, such as Queen Mary Reservoir that can be seen along the approach to London Heathrow Airport.
