Oasis is now Ojal

Oasis is now Ojal.

In Sanskrit, “Ojal” means “vision”, and “jal” means “water”.

Our re-branding reflects our plan to ensure that no human being on the planet is left without access to clean drinking water.


The wait is over!

Since our victory at the 2018 MIT Water Innovation Prize for developing the simplest and cheapest E. coli test yet, our team has been working tirelessly to make the test available to consumers worldwide.

We conducted a UNICEF-backed trial to evaluate the accuracy of the test, which demonstrated that the Ojal E. coli test is as accurate as membrane filtration, the current gold standard method. To validate the design of the test, we performed a randomized controlled trial in the slums of Kanpur, India which proved beyond doubt that even where poverty and illiteracy are rampant, people are able to successfully use the test and interpret its results.

After integrating user feedback from small-scale deployments in India, the United States, Bolivia and Mozambique for a wide array of clients, we will be launching the test with a revised form factor.

The Ojal E. coli Test will be available to individuals and organizations worldwide in the Spring of 2019.

In the short term, we have the capacity to meet urgent requirements. If your project cannot wait for our official product launch, please contact us and we will ensure that your needs are met.

custom design + Manufacture of water quality tests

An early iteration of the Ojal  E. coli  test undergoes lab validation.

Our effort to design the perfect test has inspired us to work closely with leading experts, national and local governments, NGOs, industry partners, educational institutions and individuals across the world. These interactions have made it clear to us that there is not and there never will be a single solution for all contexts. With this in mind, we have designed the Ojal E. coli test to meet the needs of most use cases, but are aware that certain clients will need custom designed and manufactured tests to meet their needs.

Our team of experts has extensive experience in designing and manufacturing water quality tests for a wide range of form factors, aesthetic considerations, data outputs and use cases, and will be happy to work with you to design a test specially for you.
