The DelAgua kit was first introduced to overcome the problem of lack of access to testing laboratories. It is now used all over the World by both Government and Non-Government Organisations as the Portable Water testing kit of choice. DelAgua also supplies all manner of water testing & laboratory equipment at heavily discounted prices to companies and individuals all over the world. This coupled with our expertise in delivering equipment to some of the worlds most remote locations, makes us the perfect `one stop shop`. In addition to water testing kits, DelAgua now designs, operates and supports large scale water treatment and testing projects in-country. We also execute Environmental Health Projects such as our project in Rwanda where we are distributing 600,000 water filters and 600,000 high efficiency cookstoves to the poorest 30% of households - see for more information.

About Us

In 1985, the University of Surrey in collaboration with Oxfam developed the Oxfam DelAgua Portable Water Quality Monitoring Test Kit. The Oxfam DelAgua kit enables field workers to test water quality in remote and isolated situations and in circumstances where there is no access to a water testing laboratory. Since its development in 1985, the water test kit is used by all the major International NGO's and other Aid Agencies in over 130 countries around the world.

In 2006, The University of Surrey and other investors founded DelAgua Water Testing Limited to take over the management of the DelAgua organisation. Consequently, various improvements have been made, including:

  • The upgrading of all kits
  • The upgrade of the design, manufacturing and distribution functions
  • R&D to produce a portable microbiological testing kit that provides quantitative results in less than 20 minutes.
  • The upgrade of existing services and the introduction of new services, including:
  • Free access to a water quality risk assessment software program on DWT's website
  • Free access to a library of reference documents on DWT's website

In addition to distributing its own kits and consumables, DWT also offers a distribution service for other manufacturers' products. The most popular products are detailed on this website, but those not detailed can also be supplied - DWT is able to source in excess of 60,000 products from numerous manufacturers.

DWT is committed to providing services and products to enable the provision of clean drinking water for everyone around the world.

Water Testing Kits And Equipment

Supplying NGOs, Governments and Companies with testing solutions, lab equipment and other products.

We have worked with the world’s major NGOs for 30 years, and in 2007 began to increase the product portfolio we could offer to them. This expanded product range allowed us to begin supplying Governments ‘in-country’ with complimentary equipment to our traditional offering of DelAgua Kits.

This in turn led to us winning supply contracts with companies and others whereby we provided a ‘one stop shop’ solution for all laboratory and life science requirements. We can now offer in the region of 60,000 products and have customers in over 150 countries.


Researching and commercialising the next generation of life science equipment and techniques

The organisation is inexorably associated with academia, which we are extremely proud of. From our origins at the University of Surrey to our current associations with LSHTM, Emory, PSU & Duke, we continue to work at the cutting edge of research and development.

DelAgua looks to invest in new technologies at an early stage and develop these into end-user led commercial devices. We aim to solve problems by making them the reason for development, rather than developing technology without purpose.

Alongside our own research and development we lead pilot programmes for projects that are yet to go to market. Our expertise in working with a diverse set of organisations means that we not only provide a fertile proving ground for new technologies, but offer a much greater chance of commercial success as well.


Designing & implementing large scale projects which help create self-sustaining communities and increase productivity for Government Public Health departments.

Our projects team is dedicated to creating the most efficient and sustainable models for improving public health on a large scale. Sustainability is at the heart of our planning, and we have made long terms commitments in Rwanda and India, with plans to employ over 5000 staff in those countries by the end of 2015.

Our project in Rwanda has taken 3 years of preparation, involved 15 organisations and hundreds of individuals have contributed at the planning stage. We aim to create communities that are healthier, more economically successful and that encourage the prosperity of future generations. Innovative forms of financing allow us to earn revenues on performance, guaranteeing commitment and ensuring the highest possible standards.

In India we aim to assist Ministries of Health to improve existing reporting and monitoring by embracing the latest technology. At the same time we will promote awareness of water safety in and amongst the rural communities, with a target of helping 10 million people by the end of 2015.
