Volunteers use sand, gravel to provide clean water in Nicaragua
Members of several local Rotary Clubs–a group of people providing humanitarian services–have joined together to provide residents in the rural mountain areas of northern Nicaragua with a filtration system that uses sand and gravel to produce clean water, according to the Englewood Herald.
Littleton Rotary, the Littleton Sunrise Rotary Club and the Aurora Gateway Rotary Club–all from Colorado–worked together to raise $8,000, which was combined with money from district and Rotary International to pay for the $21,000 project.
Members of the Somoto Rotary Club joined in to help with the installation of the filters in Nicaraguan villages.
A plastic tank acts as the filter, which is filled with 2-inch layers of coarse gravel and pea gravel, then topped with volcanic black sand. Two weeks after the filtration system is built, a bacteria layer is ready to go to work purifying 12 to 15 gallons of water daily. The sand and gravel will only need to be replaced every 18 months.
The rotary club members have installed 261 filters in the villages.
