The LWTST treats fresh water (from lakes, rivers,
wells, etc.) by pumping it first through a coarse
filter and then through a fine filter. After filtration,
a residual amount of chlorine is added to the
water. The chlorine kills any bacteria that made
it through the filters. It also makes sure that
the water stays clean and safe during storage.
How much water can an LWTST purify?
The LWTST can purify up to 10,000 gallons per
day, or 10 gallons per minute which is enough
water for 3,000 people.
Can the LWTST treat salt water?
No. The LWTST can only remove suspended contaminants,
such as dirt and bacteria. Salt is dissolved in
water and unaffected by filtration. However, the
Rapid Response
Water Treatment System can remove salt.
What is the life expectancy of the LWTST?
Five years is a conservative estimate. The system
is made from durable, high-quality material, and
as long as it is protected from the environment
and regularly maintained, it should last two to
three times that long.
How much does an LWTST cost?
Cost varies depending on configuration. For a
quotation, please contact

My church/civic club/non-profit organization
knows of a community that needs an LWTST. How
can we get a system installed there?
The answer to this depends on several factors,
as explained below. Click
here for a list of countries we are currently
working in.
If your group is able to fund the project and
the community is in a country where WMI is already
working:
WMI should be able to take on your
project. The first step is to look over the
Site
Selection Criteria. If you feel your community
is a good candidate for a Living WaterT Treatment
System or an alternate safe-water project, please
contact us.
If your group is able to fund the project but
the community is not in a country where WMI is
already working:
WMI may be able to provide a Living
WaterT Treatment System for your group's use.
WMI can also provide training in Charleston,
South Carolina, a training DVD, and manuals.
Please be aware, however, that if your community
is not located in a country where WMI is currently
active, then we may not be able to send our
staff or volunteers to provide on-site support.
If your group is not able to fund the project
and the community is in one of WMI's countries
of focus:
We will take your community into
consideration when planning our projects. However,
due to budget and personnel constraints, we
cannot guarantee that WMI will be able to implement
a safe-water solution in the community.
If your group is not able to fund the project
and the community is not in one of WMI's countries
of focus:
Unfortunately, WMI will probably
not be able to provide assistance. We have found
our programs to be most effective when we are
able to implement several safe-water projects
in a particular country, rather than installing
a single, isolated system. We regret that we
are not able to work in every community in every
country that lacks safe water. However, we are
continually expanding the scope of our work
and ask you to check back for updates on our
country programs.
I am an individual and would like to
improve the quality of my water. Can I purchase
an LWTST for my personal use?
WMI is a nonprofit organization. However, in order
to generate revenue for our projects, we are willing
to sell the RRWTS at a fair retail price. Please
contact us for more information.
I heard that the LWTST can't be used
in the United States. Is that true?
In order to use the LWTST in the U.S., the system
must be permitted by state agencies. State and
federal environmental regulations applying to
public water treatment and distribution are very
effective in protecting public health. However,
there are no provisions for emergency permitting
to supply safe water after disasters.
WMI is currently in discussion with state emergency
and environmental departments to obtain pre-permitting
for the RRWTS so that it can be used immediately
after a disaster to provide safe water to the
victims. While both the LWTST and the RRWTS are
highly effective in providing safe water, after
a disaster within the U.S. WMI engages in relief
efforts using the RRWTS.
