SECURE UNDERGROUND COLLECTION, ACCUMULATION AND STORAGE SYSTEM FOR WATER (THE "SYSTEM")

Abstract: The invention relates to a system for the collection, accumulation and storage of water supplies in a reservoir which would be a standard in city planning technology which: a) is built underground; b) can be made secure from sabotage, terrorist attacks and war, from chemical, biological and other attacks; c) would contain water collection channels; d) would contain water treatment/purification plants; e) be space-saving and can be constructed under urban built-up areas and therefore also be in close proximity to heavily populated areas; f) would be able to accumulate and store water indefinitely; g) would be able to incorporate new technologies like the generation of hydroelectric power from water flows from collection; and h) can serve as underground bomb shelters. The stored water could be used for human consumption or industrial use.

Description: SECURE UNDERGROUND COLLECTION. ACCUMULATION AND STORAGE SYSTEM FOR WATER (THE "SYSTEMS DESCRIPTION Introduction 1. There is always a need for potable water supplies, particularly in cities and in certain regions for the world where there is no regular or constant water supply. Currently, water supply is obtained from sources like rivers and lakes, open reservoirs both natural and man-made, desalination and even from natural underground wells and streams. As the world's population grows, the need for potable water supply will increase. There is no efficient collection and storage of potable water from natural supplies. Even open reservoirs lose water through evaporation. Current existing sources of water supply may not be sufficient to provide for an increase in demand for potable water. Current city planning procedures and technology do not provide for such a reservoir. 2. In addition to the foregoing, in present day situations, there is always present the potential of attack, by chemical, biological and/or other means, on present water supplies. Summary of the concept of the Underground Collection. Accumulation and Storage System For Water 3. The concept calls for the construction of concrete underground tanks which would be built generally in accordance with the drawings annexed. These tanks would store water to be used as required. Using current construction technologies, the System could be built in high density urban areas, beneath buildings and occupied areas, maximizing land use and providing a secure reservoir in close proximity to highly populated areas. The System could be made a standard for city planning techniques in the future. A variation of the Storage System could also be built under the sea-bed, in conjunction with a desalination plant. Current and future technology may also provide for the generation of electricity from the collection of water into the System. Such water as is collected would be treated, filtered and purified prior to being accumulated and stored. The System is naturally secure against physical, chemical, biological attacks and attack by other means. 4. The System can be divided into the following stages :- a. the collection of rain-water from drains and canals, diversion of streams and rivers and even from desalination; b. the generation of hydroelectric power from the water flows; c. the treatment, filtration and purification of collected water; and d. the secure accumulation and storage of such treated water to be used as and when necessary. Collection and treatment/purification of water 5. Current and future technology relating to the collection of rain-water from existing and new drains and canals and the diversion of streams and rivers and from desalination would be applied and used in the System. 6. Current and future technology relating to the treatment, filtration and purification of water would be applied and used in the System. Generation of hydroelectric power 7. It is envisaged that both current and future technology relating to the generation of hydroelectric power from the collection of water, particularly from low head running water flows, can be utilized and applied in the System. Accumulation and storage of water 8. Current and future technology relating to the construction of hardened concrete storage tanks, passages, pipes, and underground facilities for the treatment/purification and power generation will be utilized and applied in the System. A typical System is envisaged at occupying an area of roughly 600m x 600m and will be built underground. Please refer to the Drawings which are ■ described as follows :- a.

Drawing 16: Plan view of a series of Systems, linked from a water collection point; 9. The underground component of the System will comprise the following basic components :- a. Concrete tanks for the storage of water which will be built underground. (Please refer to Drawings 10, 11 and 12); b. Hardened ventilation wells and air shafts (please refer to Drawing 4); c. Pressure tanks (please refer to Drawings 1, 6, 12 & 13); d. Reinforced underground passageways connecting the storage tanks which would be wide enough to act as bomb shelters during emergencies e. A collection point for the accumulation of collected water which may be from drains, canals, rivers (please refer to drawings 14, 15 and 16); f. a hydroelectric generation system; g. a monitoring, treatment/purification filtration plant (please refer to Drawings 8 & 9); h. pumps for the output of water from storage. 10. Security of System Due to its underground nature, the System allows for the natural control of the movement of persons and allows for the monitoring persons having access to the stored water supplies by present day technology. The System also naturally limits the risk of attack by chemical and biological means. Because of its specifications, the Storage System can also function as an underground bomb shelter. 11. Other advantages of the System a. The System(s) can be built below urban areas and buildings or even golf courses, eliminating the issues of transporting water from distant regions, and providing for localized reservoir for water supply. b. Land and building owners would be able to commercially exploit each System by charging public utilities for storage and the supply of water from the System. c. Depending on the size of each Storage System, it may also act to prevent flooding of rivers, canals and drains during heavy rains, particularly in tropical/sub-tropical areas.
