Water for Waslala is a Villanova Service Trip which goes to Waslala,
Nicaragua to provide engineering consulting services to a region
which lacks water resources and has a poor quality of life.
Waslala is a city of about 40,000 people who live in the
mountainous area of north-central Nicaragua, eight hours north
of Managua, the capital. The town center contains about 8,000
people with the remaining 32,000 being out in surrounding
villages. Our task down in Nicaragua was to survey the
surrounding villages and provide consulting as to how to provide
potable water to the surrounding villages. Only about 68% of
the people in Waslala have access to potable drinking water.
During spring break,
we flew to Managua, Nicaragua and took a bus to Waslala. Our
major task in Waslala was to hike or horseback ride out to the
surrounding villages, find water sources and take GPS
coordinates in order to design a piping and tank system to
provide the water from the source to the village. We surveyed
nine villages in the week which we were down there. While we
surveyed Waslala, we looked into design ideas for certain
projects which could provide basic needs like electricity and
sanitation for the people.
The first task of the
water project was to identify the water source. The types of
sources found in Waslala were groundwater, surface water, and
springs. When the source was found, the next step was to
deliver the water. To accomplish this, we surveyed the area and
decided which type of intake manifold, pressure head and piping
network was necessary to deliver to the village. Once the water
reached the village, a treatment process would be designed to
counter possible disease or sickness. The treatment process
could include disinfection, filtration or sedimentation
depending on the quality of the water from the source. Our
design team decided on filtration to separate fecal coli form
bacteria, the main contaminant found in drinking water in the
area, from the water. Once the water was treated, it would
be stored in a tank facility and distributed throughout the
village. |
