Stage 4: Transition to Scale

Six ClariWash self-washing filters have been installed in Kisya Kagana, western Uganda and have been operating since January 2017 supplying a community of 800 people. A further ClariWash filter has recently been installed in Kamwenge district, Uganda

Registered as a Non-Profit in United Kingdom.

Problem

The use of relatively complex conventional drinking water treatment processes used in the developed world is impractical in remoter parts of the developing world due to a lack of skilled operatives, lack of maintenance parts for electro-mechanical & control systems, unreliable power supply and poor access to treatment chemicals.

}

Solution

The ClariWash system is a new concept addressing these challenges. It is a low maintenance water treatment system suitable for long term use in improving water quality for communities in developing countries. The system is hydraulically automatic and has no control system, power supply or need for operator intervention requiring only the energy of the well pump to self-wash. It has no moving parts, and no need for replacement parts.

Target Beneficiaries

For use to supply drinking water to communities in developing countries in areas where there is low technical support infrastructure. For deployment in disaster response situations where power and other infrastructure has been disrupted.

Mission and Vision

In support of the UN Sustainability Goal 6 Clean Water and Sanitation, the vision is to provide a low cost method of treated water provision without need for power supply or human intervention. The system is replicable and scalable. WaterReach are to identify and develop delivery partnerships with country technical groups and engineers involved in WASH projects to transfer and deploy the technology to local communities.

Innovation Description

The new ClariWash self-washing filtration system is a low maintenance water treatment system suitable for long term use to improve water quality for communities in developing countries which lack access to skilled operatives, technical support, spare or replacement parts. The system is hydraulically automatic and has no control system, power supply or need for operator intervention requiring only the energy of the well pump to self-wash. It has no moving parts, and no need for replacement parts. It can be constructed using available items such as plastic pipes, plumbing and tanks which keeps cost down. The system can be pre-assembled in a workshop setting using drawings and an assembly manual. Modular parts can then be erected on site. The system does not need a complex manufacturing process allowing rapid start-up at low cost. The system is replicable and scalable.

Competitive Advantage

The ClariWash filter innovation is self-washing with no moving parts or need for replacement parts. It can therefore remain operational when other innovations may suffer breakages, loss of essential parts, need for replacement of consumable items. It requires no power supply or control system which contrasts with higher technological solutions which require engineering support and skilled operatives. This makes it suitable for areas where technical infrastructure/support is minimal. The ClariWash system does not require a complex manufacturing process and makes use of readily available materials ( such as pipes, tanks, plumbing) thus making it cheap and suitable for rapid start-up..

Planned Goals and Milestones

WaterReach has a partnership with GAIND Uganda for deployment of the system and also working with charity Protos to pilot test the system on site in Uganda. The assembly of a demonstration rig show-casing the technology to visiting NGO's and charities has worked well. WaterReach is seeking to establish similar delivery partners and other technical groups/WASH engineers in other developing countries to deploy the system more widely.
