We made a tremendous discovery while we were helping the church at Monduli Juu!
By the way, Monduli is the general region. Juu means “upper.” We have rented a house in this community, about a quarter mile from this church. Our co-workers, Lewis and Tammy Short, live in Lower Monduli, or Monduli Chini.
This church–and the community they are located in–has no water supply. They carry water in from streams and ponds a couple of miles away; the same streams and ponds that are used to water animals. It’s not clean water, but it’s all they have. We proposed collecting rain water from the church building, and sharing it with the community.
Initially, we were going to buy large vinyl tanks. We told the church that we would partner with them: if they buy one tank, we will match it. But since they don’t have a lot of cash, that wasn’t working well.
We found a design for building tanks and houses out of discarded soda bottles, filled with dirt. You still have to buy cement, but nearly all your other materials are free. We proposed this to the members of the Monduli Juu church. So after collecting about 500 bottles, we set a day and started building a tank.
We drew a circle on the ground, and mixed concrete to pour a circular floor. While one group was preparing concrete, another group started filling plastic bottles with dirt. We mixed mortar, and started building a circular cistern. When one of the neighbors wanted to learn how to build this way, we all got together another weekend and worked together with her family.
That’s when we made our discovery. It took a long time to fill bottles and mix cement and lay bottle bricks, and all that time, people were chatting. They made fun of each other, and they exchanged phone numbers. They tried to figure out which friends they had in common. In short, this time-consuming, tedious process was a perfect opportunity for evangelism!
It meets a felt need: for good water storage near home.
It’s sustainable: anyone can do it with local materials (and it cleans up the environment!).
And it provides a lot of relationship-building time between the local church and the non-believers who want to learn about this method.
This was exactly the sort of project we had been looking for. This method can help us become a valued part of the community, and can be part of an indigenous evangelism effort.
And that’s how we use empty soda bottles to win souls for Christ!
