OUR HISTORY

DELAGUA WATER TESTING LIMITED

THE PROBLEM

In order to test water quality, aid agency field workers would have to take a sample and transport it to a laboratory. The sample would often have to travel a long distance, taking a long time and in poor storage conditions. Frequently therefore, the sample was spoiled before the test could be administered. What the aid agencies needed was a portable kit that could test samples in situ for the 5 World Health Organisation (‘WHO’) parameters – microbiological quality, turbidity, free chlorine, total chlorine and pH.

THE SOLUTION

In 1985, the leading water quality monitoring aid agency – Oxfam – approached Surrey University (SU) with this problem and SU subsequently developed an innovative portable water testing kit. Following extensive use in the field by Oxfam operatives, this DelAgua kit quickly became recognised as the premier portable water testing kit used by aid agencies around the world. DelAgua became an internationally well-known and highly respected brand.

 

INVESTMENT & GROWTH

Cheap competitors entered the market with under- performing imitations that threatened to undermine the portable water testing concept. So, in order to compete and continue to deliver the much needed technology, in 2006 the business was spun out of SU and into a private company – DelAgua Water Testing Limited (DWT) .

DWT invested in overseas manufacturing which cut costs by 50% and improved delivery flexibility, financial information and marketing systems, expanded the range of products sold and grew the customer base. Today DelAgua is the leading portable water testing kit brand with its kits being used in over 150 countries.

DELAGUA HEALTH RWANDA LIMITED

THE PROBLEM

As a company that specialised in water testing, the obvious next question to answer was, “When a water source is found to be contaminated, what is the solution?”

DWT conducted extensive research, working with organisations such as the Bill & Melinda Gates Foundation, PATH, Halosource, Cascade Design and its own clients including Oxfam, Loughborough University and Islamic Relief , to better understand which technology would be best suited to providing rural communities with a cost-effective method to treat microbiologically contaminated water.

 Technologies considered included various forms of chlorination, filtration followed by bromine treatment, purification via exposure to ultra-violet light and filtration.

THE SOLUTION

The solution that emerged as the best to tackle the multiple challenges: low cost, no change to the water taste, minimal behavioural change, was simply to boil water. This could be achieved most efficiently and effectively by using a stove instead of a traditional open fire.

However the end- user cost of a stove was $50 which is prohibitive for an impoverished family living in rural Africa with an average income of $1.9 per day.

So, in 2011, DelAgua explored the concept of carbon credits which would be generated by the stove and then sold to provide the funding for them. Using this model, stoves could be provided by DelAgua to the poorest people free of charge, a market that extends to hundreds of millions of households in Africa alone.

THE RWANDA PROJECT

INNOVATIVE FUNDING

In March 2012, DelAgua chose Rwanda as the project location and pledged £3m to register the project with the UN.

Over the next year, a 100-household pilot was conducted, followed by a larger 2000-household pilot. Key metrics were gathered including amount of non-renewable biomass being used as fuel, level of fuel usage, source of fuel usage, in order to set a baseline from which reductions in emissions resulting from the intervention could be measured. Today, DelAgua can produce circa 2.5 Certified Emission Reductions (CERs) /annum/new stove and circa 4.0 Verified Emission Reductions (VERs)/annum/new stove.

Carbon credits generated by high quality cookstove projects typically command a premium price because of the “development dividends” that come from the project. In addition to reducing carbon emissions that are produced when wood is burned, the project also offers significant health, economic and gender benefits. Consequently, Supranational and National bodies are willing to pay significantly higher prices as a, “pay-for-performance” aid contribution. Companies are also willing to pay higher prices for these credits to offset their carbon footprint. Their staff and customers value the association with a project that delivers multiple benefits to people most in need.

To date the project, funded by the sale of carbon credits, has distributed over 600,000 stoves free of charge to rural households, benefiting 3 million Rwandans.
