What is your signature innovation, your new idea, in one sentence?

Colloidal Sivelr Impregnated Ceramic Water Filters (Silver Filters)

Describe your innovation. What makes your idea unique and different than others doing work in the field?

Silver Filters are a great Point of Use solution to contaminated water; they are inexpensive, easy to use and maintain, and neraly 100% effecdtive against water-borne disease.

Delivery Model: How do you implement your innovation and apply it to the challenge/problem you are addressing?

We are working with local potters using local materials and creating employment along the production and delivery chain. We produce, market and deliver the product. Making Silver Filters available to those without pure drinking water will immediately improve their health.

How do you plan to expand your innovation?

Through marketing efforts aimed at increasing sales and distribution.

Do you have any existing partnerships, and if so, how do you create them?

Potters for Peace (PFP) and Potters without Borders were instrumental and valuable in teaching us how to produce the filters to standard protocols established by PFP. Wecould not have done it without them.

Provide one sentence describing your impact/intended impact.

The local people who have come in contact with the Silver Filters love them for water purity, ease of maintenance, low price and taste.

What are the main barriers to creating or achieving your impact?

Distribution channels and limitations to production, ie. current production capacity.

How many people have you served or plan to serve?

This is a new enterprise and we are working on produiction of our first 1000 filter order. Two pilot projects distributed around 290 filters to date.


This is all an effort aimed directly at home consumption.



Please list any other measures of the impact of your innovation?

Safe drinking water improves the general health of the family and protects the family economy. Sick persons can't work or go to school. Healthy families survive, unhealthy families do not. Over the long-term, we would hope to see a reduction in infant and child mortality rates due to intestinal problems arising from unbafe drinking water.

Is there a policy intervention element to your innovation, if so please describe?


Exactly who are the beneficiaries of your innovation?

All people who lack access to pure drinking water, i.e. the entire Yemeni population. Rural residents who rely on surface water for drinking water are most affected and are therefore the natural target consumer.

How is your initiative financed (or how do you expect your initiative will be financed)?

Support from the German Embassy and GTZ to established the kiln and provided the training to learn how to make the filters. Now, it is an entirely private affair.

Provide information on your finances and organization:

There is no budget; we invest a portion of our receipts to make site improvements. Currently, we are focused on obtaining new business.

What is the potential demand for your innovation?

All of Yemen lacks potable water. Those with sufficient income can purchase pure water while those without adequate income must drink the available water. Most rural residents cannot afford to purchase water or lack access to pure water other than bottled water. This is expensivve especially if it supplies all your dirinking water needs. We have 8 employees.

What are the main barriers to financial sustainability?

We will become financially stable once we start selling our product more widely.

The Story
What is the origin of this innovation? Tell us your story.

The innovation originated in Guatemala in 1981. Potter for Peace has taken it to commercial levels first in Nicaragua and then in 11-15 other countries. There is no patent and anyone with the initiative can adopt the technology to local conditions. We started with nothing more than idea to build a more efficient gas-fired kiln to promote Clay Pot Irrigation. Then the idea to produce water filters came to the attention of Dr. Michael Klingler, Team Leader of the GTZ supported Integrated Water Resouces Management project.
