LORENTZ smartTAP combines
hardware, software and predefined
business models to allow for water
infrastructure to be delivered in an
economically sustainable way.
Users of the system access water
from a tap using a tag. The tag is precharged with water credits at a local
shop or directly with the connected
optional GSM modem.
The revenue collection function allows
the system to be maintained, any
investments to be returned and for
the system to be expanded to more
users.
The LORENTZ smartTAP solution provides the
necessary technology for sustainable water solutions
anywhere in the world.
The LORENTZ combination of field experience, hardware design, manufacturing for off grid environments
and software development results in a solution that is
reliable and flexible.

The LORENTZ smartTAP components allow for not only
a single tap deployment, but also for a fully scalable
multi community solution. The modular design means
the system is cost effective at any size.
The system analyses and reports any problems for long
lasting service. Hardware is designed to be repairable
with low skill levels and limited training. Sub unit parts
are simple to replace and can even be repaired down
to component level in country, making smartTAP a
dependable long-term solution.
