Hola Tanita Preston ! I do see some potential for collaboration and partnership between our organizations in Colombia. I will email you later today so we can continue this conversation!

Hello Ashley Tillman  thank you for your interest in our project and for your support in this challenge! AguaClara Reach firmly believes in a grassroots approach to ensure sustainability and long-term usage of our water treatment systems. We partner directly with local civil service organizations, such as NGOs that have experience in the local water sector and have established relationships with the communities in which they work. We first engage our partner and their project staff (including a team of engineers, community mobilizers, and managers) to undergo a series of thorough training sessions to orient them on AguaClara technologies. This includes engineering principles, design decisions, and operation and maintenance procedures. We believe in a very thorough technology and knowledge transfer to our partners in order to make our partners the local experts. During these training sessions, we also gather feedback on how to tailor operation and maintenance training for local community members. Our partners have many decades of experience working in their region and have the best knowledge on how to best engage their constituents. Recognizing our partners' strengths in this regard, we utilize our "train the trainer" model to allow our partners to tailor training to best fit the community’s needs and train the communities under our technical guidance.

Sustainability is at the core of AguaClara Reach’s operations. Our systems are sustainable in under-served communities because:
- Operation and maintenance is simple (can be done by a local operator) without sacrificing quality (we meet World Health Organization standards for drinking water quality, and we also meet the more stringent US EPA standards the majority of the time),
- Cost of O&M is one-third that of conventional plants (India: $1-2 per household per month for 90 liters of water per person daily; Honduras: $2-5 per household per month for 120 liters of water per person daily), and capital costs are one-half that of conventional plants,
- Systems are built by local labor, using local construction practices, and using locally-available materials (plastic drums, PVC pipes, and sand),
- Designs are modular, especially the PF300, making it easy to remove parts for maintenance or repair,
- All tanks are open so the operators have visual feedback of system performance, allowing them to develop intuition for operation,
- The processes are high-rate (fast), facilitating rapid response to sudden changes in raw water quality and minimizing water waste,
- They use inexpensive and easy to operate features such as “pipe valves” to replace components that need more frequent replacement, such as ball valves, whenever possible,
- Use of sloping geometries for self-cleaning sedimentation tanks.

Women and girls share the overwhelming burden of collecting water for household needs. In our project areas, prior to the introduction of AguaClara systems, the time spent collecting water is upwards of 30 minutes at a time, with an average of over 10 trips to gather enough water for daily consumption. Since this takes a large chunk of time, the act of collecting water limits the ability of women and girls to contribute to the local labor force, education systems, and the community as a whole. By making clean water more accessible, we hope to reduce the incidence of waterborne disease and thus allow community members to peacefully lead healthy lives. Less sick days means more productive work and school days, which in turn leads to a revitalized economy. Individual peace thereby leads to overall community prosperity.

I hope this answers your questions, but if not, let me know and I can expand further!

Thank you for your comment abubakar Mbarak The PF300 utilizes the same steps as conventional water treatment plants such as coagulation, flocculation, sedimentation, filtration, and disinfection. Yet each of these processes are designed in such a way that they are completely modular - they are fabricated inside plastic drums and easily fabricated tanks so they are easily transported. This is our solution for smaller villages, where the capital costs of a larger plant are too high to be economically feasible in these areas. Let me know if this answers your question! If not, I can go into further detail about how each stage in our water treatment train is designed to give a further understanding of how it is functional without the use of electricity, pumps, or sensors.
