Before the tanks were built, each of the three communities received water for only a few hours each day. Building the tanks greatly increased the capacity.
Water is pumped to the tanks from a deep well located approximately two kilometers from the site. When it leaves the tanks, the water is distributed to three nearby communities.
The storage tanks were designed by the Iowa Professional EWB Chapter and built with the help of the local community. To assist in construction, chapter members were able to travel to Tierra Blanca for a week at a time in 2012 and 2015.
