MAJI (Water)
In embarking on our water filter project, we sought to explore the transformative impact of positive changes in infrastructure, viewing these ripple effects as an interconnected chain of benefits. Termed the "effect chain," our focus was honed by aligning with the Sustainable Development Goals outlined by UNOPS, serving as a guiding value system. Upon closer examination, the positive change extended beyond the provision of clean water; it profoundly influenced the health of the community. Moreover, this service not only liberated time but also held the potential to positively impact education and culture. Our ultimate goal was to ensure universal accessibility, fostering equality through a system that transcends boundaries.

Brief
After closely examining our target values and the existing circumstances, we were able to specify the particular aspect of water supply we aimed to address – specifically, the provision of drinking water. Our final knowledge gap revolved around determining the optimal per capita daily water requirement based on biological needs, considering factors such as age, gender, and the unique geographical and climatic conditions in Mombasa.
Ultimately, we established a per capita water amount ranging from 2.7 to 3.7 liters. Recognizing the importance of societal impact for maximum effectiveness, we aimed to work within people's homes to bring about significant change.
The Challenge
Upon a thorough examination of our targeted objectives and the prevailing circumstances, we have refined our focus to specifically address the domain of drinking water supply. Our primary concern was centered around ascertaining the precise quantity required per capita per day, factoring in biological necessities. This determination considered various demographic aspects, including age, gender, and the unique geographical and climatic conditions of Mombasa.
Location
In this early conceptualization, it was evident that Maji, like our test unit, would also be attachable to ensure compatibility and flexibility with the most common water jerrycans.The directional sculpture is designed to fulfill all functions and requirements for its later use. A crucial aspect of the architecture is a logical division of the volume. This includes compartments for the filtered water, a carrying handle that doubles as a pump, a designated space for hoses, and, of course, the primary filter, to highlight the key components. The use of simple and straight lines facilitates easy repair and replacement of individual parts. Larger radii are incorporated where the filter is gripped and at the spout of the water container, ensuring an intuitive and user-friendly experience.
Ideation
Parts and Details
Central to our design philosophy is not only simplicity in aesthetic realization but also an interior that forsakes all unnecessary elements to minimize potential weak points. A key aspect of this approach was the deliberate decision to forgo electronics.
Maintenance
As Maji is utilized and managed by people in a self-responsible manner, maintenance is designed to be simplified and as infrequent as possible. Drawing from our researched examples and anticipating future developments, the filters are recommended to be changed every 10,000 liters, equivalent to 500 Jerrycan fillings. Replacement filters would be delivered to the Community Kitchen by Halfull staff. To replace the filters, one only needs to remove the housing for the tubes and unplug the maintenance cover, making it a straightforward process to change the pre-filter and main filter.
Flexible In Use
In exceptional situations, Maji proves to be versatile and reliable. When used outdoors, Maji can be placed directly on the floor after removing the jug attachment. The included tubes eliminate the need to attach the module this time. Stability is achieved by pressing on the knee, and the pumping process can commence. This allows dirty water from one tank to be filtered directly into the clean tank. In large numbers, Maji could be employed in crisis areas to replace or compensate for destroyed infrastructure until it is rebuilt.
Material Selection
Material requirements are inherently tied to durability, corrosion resistance, and food safety. Sustainable raw materials with ample availability were crucial considerations. The housing is crafted from resilient aluminum, further fortified through an anodizing process. Aluminum, abundant in the earth's upper crust, is easily processed and boasts a high recycling rate. For the jug top, providing users with a clear connection to clean, filtered water was vital. Opting against glass due to its fragility, a semi-transparent polycarbonate was selected. Natural rubber ensures tightness where necessary.

Jua Kali Craftsmenship
The Jua Kali, skilled craftsmen in Mombasa and Kenya, excel in upcycling, recycling, and crafting new products using various raw materials. We aim to establish a collaboration with the Jua Kali from the outset because their exceptional manual skills and machinery make them the most efficient option for maintaining our device hardware. This partnership not only ensures effective maintenance but also connects us with the local community, allowing the system to operate independently.

EMPOWERING
Discussions with the Jua Kali have shown their enthusiasm for such a collaboration. They would not only handle maintenance and repair but could also participate in filter production. Halfull would provide them with a kit containing only the parts that can't be locally sourced. The remaining components would be crafted on-site using materials like old buckets and corrugated iron, enabling individual adaptation in terms of function and visual appearance, as the local craftsmen best understand how it should work.
Forging Relations
Prototyping
As a follow-up, we successfully created a mock-up of MAJI, aiding us in refining and providing a platform for future iterations. This prototype not only showcases the project but also conveys its meaningful concept, making it tangible and understandable for people.
