Design Specifications

The Waterbag is made from durable Food Grade plastic that stores up to 10 L of water. The water is collected in the Waterbag and a PUR packet is added to the bag and is closed. The bag is then hung (from a branch or other device) and mixed for 5 minutes. The bag should be left hanging for 25 minutes, allowing all particles to settle at the bottom. Water can then be dispensed with the nozzle on the bag. An instructional video is available on the DayOne website.

As per Bob: Manufacturing
of this type of product requires documented process and assembly
standards. In volumes of 100 special
attention needs to be paid to ensure that each unit is not a unique â€œone ofâ€
but rather follows and industrialized, documented and controlled assembly and
test process. With the exception of the
setup and assembly/test of the actual UV unit no special manufacturing
processing is required.

Trained users imply that training processes and support materials will be made available. Ongoing application and service support will be required. Trainers will be required to develop user guides and training classes.

This product states that repair parts will not be available and that support will not be provided to the customer by the manufacturer. This is not practical for an installed base of more than ~50 units. The global distribution to both Africa and India will require 24 x 7 staffing and when repair is required the unit will either need to be returned for repair or repaired on site by someone sent out from the factory. Neither approach is practical.
