Evaluation of Height, Area, and Capacity of Concrete Elevated Water Reservoirs in a Tertiary Institution in Benin City, Nigeria

Abstract

The objective of this work is to determine the height, area, and capacity of two concrete elevated water reservoirs in a Tertiary Institution in Benin City, Nigeria, to serve as reference to existing controls for future monitoring exercise. The two water reservoir involved in reality are of different shapes and sizes. The elevated heights, areas, and capacities of reservoir one and two suspended above their legs are: (8.106m, 362.778m², 2940.680m³, and 7.485m, 320.400m², 296.132m³), respectively. The total heights of the reservoir one and two above ground level (AGL) are approximately 22m and 18m. Statistical analysis of uncertainty in height measurement showed, 0.0153 for reservoir one and 0.0412 for reservoir two. The provision of the necessary information by the REM method about the elevated water reservoirs showed its efficacy. This method is recommended for use in the measurement of inaccessible structure/feature. The type of data and information such as provided in this work are required for institutional water board documentation, water use planning, and archival purpose.
