Throughout the world the necessity for a wholesome water supply is essential to sustain the life and health of humanity. Many areas of the world have population concentration where local water resources cannot support the demands placed on the limited water supply. Through the ingenuity of engineers, construction of very complex water transport and storage systems have been successfully implemented to make remote water resources accessible to population centers hundreds of miles away from the water source. Increased demands for limited water resources continued to challenge engineers for unique solutions to enhance water preservation and utilization. Precious water resources have become of paramount importance to governments and the populous at large. With the now intense emphasis on conserving and protecting water supplies, a very unique water storage concept has been developed which accomplishes these objectives. The Revoc® Elevated Water Reservoir (EWR) System when implemented will conserve, increase storage, and protect the precious water supply. This new concept incorporates three complex primary elements into the storage system. The three primary elements for the Revoc® EWR System consist of an elevated freestanding reinforced concrete perimeter wall system, a mechanical tensioned floating cover system and an impermeable reservoir lining system. The combination of these three primary elements of the Revoc® EWR System provides the capability for an efficient and unique water storage system that has not been incorporated, to my knowledge, into storage systems anywhere in the world.
The Revoc® EWR System allows for installation upon practically any size, shape and configuration where as conventional storage methods have typically been limited. The Revoc® EWR System allows for complete flexibility in that it may be installed in conjunction with a completely new storage facility or it may be added to an existing storage facility. In either case, easily 20 to 40% increase in storage volume can be realized by installing the Revoc® EWR System on a given reservoir site without the need of utilizing additional land area. Generally, the Revoc® EWR System would be well suited for applications in conjunction with earthen embankment type reservoir construction. Where a water system operator has a need to expand storage requirements it will be possible to save substantial sums of money by installing the Revoc® EWR System on an existing storage facility to accomplish the desired storage capacity.
Given that the Revoc® System is not constrained by shape or configuration of the reservoir geometry the reinforced concrete wall which provides for structural integrity of the complete system can be designed to sustain any individual or combined loading conditions typically experienced in reservoir storage facilities. The reinforced concrete reservoir wall does not require the development of hoop stress to withstand internal or external loads thus allowing for the wall to be constructed in a straight line. Typical loading conditions in which the Revoc® EWR System can be designed to withstand includes seismic wave slosh and weather conditions such as gale force winds, high and freezing temperatures.
In summary the Revoc® Elevated Wall Reservoir System is unique for the following reasons:
