After volunteering as an intern, young graduate establishes a thriving water bottling firm

Ruth Mwanzia’s entrepreneurship journey is a story of resilience, patience, hardwork and determination. She was born in a remote village in Kyondoni in Kitui West; a semi-arid place where fetching water   is the order of the day. She vividly remembers that bathing, doing laundry and domestic chores was a luxury due to the scarcity of water in the region. “Growing up in the village, there was a serious   water shortage due to irregular rainfall,” she recalls.  Mwanzia came to the city at a tender age when she was in class five. After her secondary school education, the Koola Waters’ founder and Chief Executive Officer (CEO) pursued a degree course in communications at Africa Nazarene University where she majored in electronic media. Her goal was to become a broadcast   journalist. “In order for me to graduate, I had to secure an internship and therefore I applied for numerous jobs with local media houses, but two years down the line, no opportunity was forthcoming,” she recalls.  She was on the verge of giving up when she got an internship opportunity at the Water Resources Management Authority (currently known as the Water Resources Authority).

At the time, the organization was having challenges with organizing events such as the World Water Day, and the World Wetlands Day. “Most employees in this organization were engineers who were not well versed with communications and events’ organization,” she says adding that given her training in communications, she assisted them to fill that gap.  It was a good opportunity for her to hone her skills and even though she was not getting any allowance, she seized it. After the expiry of her attachment, she volunteered   for one year in order to gain more experience.  Fortunately, Mwanzia was hired after one year as a communications assistant by the organization, thanks to her passion and resourcefulness.   She would later rise through the ranks to become the assistant corporate communications manager. “I worked there for four and a half years before I quit,” she says.  “By that time I had started Koola Waters as a side hustle and given my experience, I was ready to grow the young business to the next level,” she adds.


It was during this time that the thoughts of transforming her village by providing water to the local community came to life. Her family believed in her business idea and they invested in it. At a tender age of twenty four years, she became the chief executive of the new venture.

In October 2014, she purchased   a small machine and bottles for packaging water and one of the investors offered her some premises to run the business.  To save on overheads, her sister volunteered as an employee during the startup stage of the business when every coin that was being generated had to be used prudently.  The company has since grown to be a brand to reckon with in the Kenyan market.  Mwanzia attributes that to teamwork and commitment from her employees as well as loyal customers.

Market penetration

In order to penetrate the water bottling business  that  is traditionally  characterized by cut throat competition ,  the young entrepreneur  came up  with an  innovative and inexpensive marketing  strategy.  For instance, she   branded   the delivery track after which she received about six calls from potential customers.  In addition, she offered her customers free merchandise.  Most importantly, her product was competitively priced. “Currently the demand has grown   and sometimes we really get overwhelmed by orders, forcing us to work round the clock,”   she says with a smile. Most of Koola Waters’ customers are in Kiambu County.


 Koola Waters has invested heavily in a modern production line.  As a requirement  to do this business,  the  company  has also  secured  licenses  and  permits  from state bodies like the Kenya Bureau of Standards  and  Kenya Revenue Authority –  an expensive   exercise  that requires a lot of patience.   

Hiring the right people is also not a walk in the park.  By the same token, she says that the company has had to severe its   relationship with some distributors who defaulted on their payments.  The company’s strategy is to conquer new territories gradually after undertaking thorough market research.  It is considering expanding to Mombasa and Kisumu by the end of this year.


In 2016, Mwanzia got an award from her alma mater – Africa Nazarene – because of supporting the university’s scholarship kitty.  In 2018, Avance Media recognized her for being among the top one hundred most influential entrepreneurs in the country.  She has also been featured by CBNC Africa, besides attending many local and international entrepreneurship conferences.

As an employer, the warm lady stands out because of giving jobs to the less privileged members of the society. “I have deaf people and albinos in my team who are very resourceful despite their physical challenges,” she says. The company is planning to have a fully automated factory in the near future in a bid to raise its production. Going by her zeal, that is a feat that the young and focused entrepreneur should be able to achieve with ease.
