PWSDS- Water Storage and Distribution System

Introduction:

Disasters are happening daily and all around the world.

Very often the drinking water supply is functioning partially (or not at all) and/or also water are contaminated. Water crisis and emergencies can also occur due to:

  • Poisoning the water;sabotage of water facilities
  • Vandalism and prohibited Entrance
  • System malfunction

 

People can survive days without food, but only hours without water. Lack of drinking water needs to be addressed immediately, and it is one of the first issues authorities need to deal with in any disaster or emergency. Water needs to be supplied to the population and to the first responders and rescue teams.

The short term objective is to supply minimum amount of water needed until the normal water supply system will become operational.

The following chart summarizes the logistics considerations of water crises:

A backup water system for emergency needs to address the following requirements:

ü  Portable

ü  Quick and easy deployment

ü  Small storage area when not in use

ü  Minimum or no maintenance

Water Emergency Guidelines – The Israel Experience

Based on extensive experience of dealing with emergency situations, the Israel Water Authority has developed the following guidelines for water crises:

  • The local municipality/water utility is responsible to provide water in a case of water crises.
  • The system should be based on portable water storage distribution systems, which can be easily and quickly deployed.
  • The water distribution station should be arranged so an individual will not have to walk more than 400 meters (450 yards) to get water.
  • Crises duration expected to last up to 10 days (until normal water supply is renewed).
  • Minimum drinking water per day per person is 4 liters (1 gallon water).
  • The authorities need to able to supply water for up to 50% of the population.

 

Based on those guidelines EZPack Water has developed its Portable Water Storage & Distribution System (PWSDS).

The EZPack bladders are available at sizes from 50 liters (~10 gallons) up to 20,000 liters (~5,000 gallons). The various sizes availability allows the PWSDS to be built according to site requirements (number of people to be served; frequent of water supply; etc.).
