Pressurized Emergency Water Storage – No Pump or Electricity Required!
WatrWise™ develops innovative water storage systems for your home. WatrWise™ EWS – Emergency Water Storage – utilizes patented and patent-pending technology that automatically refreshes stored water reserved for you to use during water service or supply interruptions; supplying fresh pressurized water throughout your home, for use during an emergency.
Pressure tanks are available in many sizes and can be combined into manifolds of two or more pressure tanks to store more water; water reserved for use during an emergency.
The tanks are automatically cycled to ensure a fresh water supply. Every time water is used, water from the tank is used first, and replaced – cycled – every time you use water.
Hurrying to the store to buy bottled water when water service is interrupted is not needed when you have pressurized emergency water conveniently stored at home ready for use; no buckets or bottles necessary! Pressurized water is available throughout your home. WatrWise™ EWS is installed within your home’s existing pressurized water supply system and water flow throughout your home during every day operation is unchanged.
While flow is unchanged, WatrWise™ EWS uses pressure differential to cycle or refresh water stored in the pressure tank(s). This requires pressure in your home to fluctuate approximately 15 PSI. For example; normal incoming Water Supply pressure is 75 PSI, operating pressure differential would allow between 60 and 75 PSI as the operating pressure range in your home; while you are using water. When you are not using water the pressure tank(s) is recharged to 75 PSI. WatrWise™ EWS uses this pressure differential to cycle or refresh water stored in the pressure tank(s) during everyday use. WatrWise™ EWS is fully adjustable and can be adjusted for optimum operation, based on your Water Supply pressure, and personal preferences.
This patent-pending invention – WatrWise™ EWS – prevents stagnation by cycling water stored in the pressure tank(s). When WatrWise™ EWS is connected to a municipal water supply the incoming water is already treated for removal of suspended solids, bacteria, algae, viruses, fungi, and minerals and maintains the integrity of the already treated water supply. The water used needs no additional purification or treatment to be safe for drinking and sanitation.
WatrWise™ EWS can also be installed on rural water supply systems and private wells. When connected to a private well or rural water supply, the water is regularly cycled through the pressure tank(s), reducing incidence of stagnation. WatrWise™ EWS is not intended to be a water purification or treatment system. See Improved Access to Water
The patent-pending water storage system incorporated into WatrWise™ EWS allows for operation as part of the existing water piping network in your home and has a check valve used to automatically prevent water flowing back into the water supply should water supply fail to supply water; reserving stored water for use in your home; also a valve is installed that can be turned off to isolate your home from the water supply during water service or supply interruptions; and to also protect stored water from a contaminated water supply that may continue to supply water to your home; a water supply damaged during a catastrophes caused by weather – hurricane, blizzard, flooding etc.- and also damage caused by earthquakes, tsunami, volcanic eruptions and terrorist attack. Under normal, everyday operating conditions (non-emergency) the flow of water is enabled under pressure from the existing water supply. See Reserved Water Storage.
WatrWise™ EWS utilizes hydro-pneumatic or captive air pressure tanks to store water. In previous emergency water storage designs, water storage was limited to either a non-pressurized tank that does not have the ability to store water under pressure; or the design used a tank that stores water under pressure, but cannot supply pressurized water during an emergency or during water service or supply interruptions, without a pump; requiring electricity (that may not be available during an emergency). Storage tanks of this type act like a large pipe only allowing water to flow-through them to prevent stagnation; when the water supply is interrupted pressure and flow into your home is interrupted. Tanks of this type require you to drain the tank into a container (bucket or bottle etc.) through a hose bib or valve.
WatrWise™ EWS benefits go beyond emergency water storage by also lowering peak demand challenges for water systems. Peak demand is lowered because WatrWise™ EWS temporarily isolates Water Users from Water Supply while continuing to supply pressurized water to Water Users. Water Supply temporarily need not deliver water to these Water Users, enabling Water Supply to supply water elsewhere.
WatrWise™ EWS, “relates to water supply demand challenges related to available water reserves caused by seasonal and diurnal peak water demand, emergency water demand such as firefighting efforts and service or supply interruptions for municipal or rural water systems, while also reducing incidence of stagnation in connected pressure tank(s); and more particularly to a water storage apparatus that uses one cycle valve, at least one pressure tank and at least one check valve connected to water service lines that are connected to water mainlines that are connected to municipal or rural water systems. This method and apparatus can reduce water system peak demand challenges and automatically cycle or draw down pressure tanks; while storing regularly refreshed water for use by the water user or customer during service or supply interruptions, commonly called emergency water storage.”
