Community Profile

Mbuuni Self-Help Group was formed in 2010 and currently has a huge membership of 254 people; 194 men and 60 women. The group is located in Mbuuni Village, which has a population of 1,978 people.

The average household size is five, and the average age of the group members is 45. The main sources of income are farming and casual labor – if one doesn’t own their own farmland, they’ll look for work on someone else’s farm. Most people earn less than 10,000 shillings ($100) each month.

This self-help group has been involved with us for two years now, and their aim is to bring much-needed water to their region. We stand alongside them, providing the tools and finances needed to achieve this goal.

Mbuuni Village has a population that’s nearing 2,000 people – and they all used to rely on just one borehole. This was installed by the Machakos County government, which would charge people for each jerrycan of water collected from the pump.

Those who couldn’t afford that water, dug holes in the sandy bed of Thwake River to access its water.

There isn’t only one clean water source in Mbuuni, thanks to our partnership with self-help groups. We built a sand dam and hand-dug system that supplies clean water.

This water isn’t free. The fees paid by users are kept in the community for pump maintenance and development opportunities. But with such a large population, these two wells are not enough. One water point can only reasonably serve a few hundred people. That’s why multiple projects in one community is important.

And there are still families living a great distance away. As of now, many families spend a lot of time walking to and waiting at these clean water points.

Thus, we have accepted the self-help group’s application to construct two more sand dams and well systems in Mbuuni.


Continuing hygiene and sanitation training is part of our relationship with Mbuuni. They’re doing a great job implementing everything they’ve learned, including building and using latrines, bathing shelters, and handwashing stations.

There’s 100% latrine coverage, and almost everybody has a bathroom for washing every morning. Almost half of household have a hand-washing station called a “tippy tap,” a jerrycan that pours water as a string tilts it.

About 75% of people are treating their water before drinking it. Though water from these wells is clean when gathered, it should be treated after transportation and storage.

Here’s what we’re going to do:


We recently visited over a dozen households to check on sanitation and hygiene standards. One of the most impressive households we visited was that of Mrs. Nduku Mutua (pictures on this page). These visits inform our trainers on what they might need to review with the community during their next trainings. We will continue to teach about the importance of handwashing, for though Mrs. Mutua has a tippy tap, many neighbors still don’t.

Hand-Dug Well

This particular hand-dug well is being built adjacent to this group’s ongoing sand dam project (click here to see), which will supply clean drinking water once it rains. We have supplied the group with the tools needed for excavation. With the guidance of our artisans and mechanics, the excavated well will be cased, sealed with a well pad, and then finished with a new AfriDev pump.

Excavation takes a month or more on average, depending on the nature of the rock beneath. Construction of the well lining and installation of the pump takes 12 days maximum. The well will be lined with a concrete wall including perforations so that once it rains, water will filter in from the sand dam.

This well will be located in Mbuuni Village, and will bring clean water closer to families having to walk long distances for their water.

This project is a part of our shared program with Africa Sand Dam Foundation (ASDF). Our team is pleased to provide the reports for this project (edited for clarity) thanks to the hard work of our friends in Kenya.

Project Updates

06/15/2018: Mbuuni Community Well Project Complete

Mbuuni Community, Kenya now has a new source of water thanks to your donation. A new hand-dug well was constructed adjacent to a sand dam. The dam will build up sand to raise the water table and naturally filter water. Community members also attended hygiene and sanitation training, and plan to share what they learned with their families and neighbors.

New Knowledge

The first hygiene and sanitation training done for this area was in March 2017. Trainings thereafter are intended to cover weaknesses we notice during household visits. After a follow-up conducted in July 2017, there was a clear need for a review because very little had been achieved by the group members.

Reviewing the group’s progress in establishing good sanitation facilities at home.

Training was in the homestead of Gideon Kiilu and attended by 210 group members over the course of a few days. It was very sunny during training, so everyone kept shifting their chairs around to be in the shade.

We informed group members of different ways to treat water. They were very curious about learning the pros and cons of each method.

As for weaknesses, we realized the majority of latrines had open pits that allowed odors to escape and flies to enter. For new content, we taught group members how to make their own soap. Many members had already been mixing their own soap but admitted that after a few days it would spoil and have to be thrown away.

This session was particularly interesting for group members who wanted to fix their process and produce good soup for sale.

“According to how group members expressed interest in the training, I think it will change our lives,”70-year-old Gideon Kiilu said.

“For instance, on the issue of diseases, we have learned how we can prevent waterborne diseases. That knowledge will help us. We have also learned about making soap, which is a very important activity. It will help us change our hygiene standards and increase incomes.”

Hand-Dug Well

We delivered the experts and materials, but the community helped get an extraordinary amount of work done. They collected local materials to supplement the project, including sand and water.

A hole seven feet in diameter is excavated up to a recommended depth of 25 feet. (Most hand-dug wells don’t reach that depth due to the existence of hard rocks between 10-18 ft.).

A bucket continuously hauls up the material the excavator clears.

The diameter then shrinks to five feet when construction of the hand-dug well lining is completed. This lining is made of brick and mortar with perforations to allow for water to seep through. Sand builds up around the well walls and will naturally filter the rainwater that’s stored behind the dam.

Once the construction of the lining reaches ground level, a precast concrete slab is laid on top and joined to the wall using mortar. Four bolts for the hand-pump are fixed on the slab during casting. The mechanics arrive to install the pump as community members watch, learning how to manage and maintain the pump for themselves.

The well is then given a few days after installing the pump to allow the joints to completely dry. Communities are advised to pump out the water that seeps into the well after it rains for the first time because it needs to be cleaned out after construction. After pumping that for a while, the water turns clean and clear.

The pump was installed level with the top of the sand dam (click here to see that project) because as the dam matures, sand will build up to the top of the wall. We wouldn’t want the pump to be buried by sand!

The more sand that’s built up, the less this well will look like an island, and people will no longer have to use the steps to get up to the pump.

04/18/2018: Mbuuni Community Hand-Dug Well Underway

A severe clean water shortage still affects hundred of families living in Mbuuni Community. Families are having to walk long distances to find clean water, wasting hours of time and tons of energy. Thanks to your generosity, we’re working to install a clean water point nearby and much more.

Get to know your community through the introduction and pictures we’ve posted, and read about this water, sanitation and hygiene project. We look forward to reaching out with more good news!

Project Type

Dug Well and Hand Pump

Hand-dug wells are best suited for clay, sand, gravel and mixed soil ground formations. A large diameter well is dug by hand, and then lined with either bricks or concrete to prevent contamination and collapse of the well. Once a water table is hit, the well is capped and a hand-pump is installed – creating a complete and enclosed water system.
