Safe Drinking Water from Harvested Rain Water (RAINSAFE)

Download PDFDownload PDF
The purpose of the project is to bring the RainSafe™ machine, which treats harvested rain water to drinking water standards by means of UV and Ozone sanitisation with pre and post filtration to the worldwide market. By relying on completely natural methods of water treatment and ensuring an efficient running model, the RainSafe™ provides an affordable and viable decentralised water management solution. Implementation of the project will allow a reduced reliance on traditional water extraction, treatment and distribution models which are costly from an energy, capital and chemical/environmental perspective. Harvesting rainwater at source provides additional benefits in the areas of pollution control and storm water management. Project partners were selected with a view to eliminating significant barriers to the market. These barriers are identified as being in the areas of product certification, distribution, manufacturing and water testing/environmental assessment. Two of the partners will also host demonstration sites to assist with on-going product assessment and dissemination of product information. Additional host locations will be identified for further demonstration sites.


The RainSafe™ treats harvested rain water, well water or municipal water to bottled water standards by means of UV and Ozone sanitisation combined with filtration. Using only natural treatment methods, this affordable appliance which is also economical to run will benefit consumers by offering a viable solution for decentralised water management. It also offers the potential for water utility companies to reduce chemical usage and reduce stress on their distribution networks. 


  • The RainSafe™ market launch was delayed by technical issues which necessitated design modifications. In the interim, the coordinator maintained the relationships established with distributors prior to the project start and continued to pursue new opportunities, in particular with dealers in the UK. New relationships with UK water utilities were established with strong potential for collaboration in the near future. The company has also signed a contract to supply a Global Water treatment system company with RainSafe™ devices under an OEM deal commencing in 2015 covering EMEA and Australia.
  • Finalisation of the Bill Of Materials (BOM) is almost complete. Initial production machines have been built and are uder evaluation prior to the full production start-up in Q3. The consortium will examine the question of the timing for the transfer of the manufacturing process to other Flextronics sites as required to support market access. Consideration in this matter will be given to the volume and origin of orders and the level of maturity of the manufacturing process.
  • Market analysis work (focus group studies and customer/stakeholder surveys) was completed by GreenLife. Promotional materials have been structured accordingly.
  • The major focus for the coming months of the project is to complete the LCA and LCC work, which commenced at Exeter and will progress further when BOM’s are fully finalised. Following this work, associated tasks of the consumer validation and cost modelling will be addressed.
  • Demonstration sites were completed in late 2014/early 2015. They are located at: GreenLife in Schwerin, Germany; The Dental Hospital at Trinity College, Dublin; The premises of a Belgian distributor; The home of an OIIL employee; The Innovation Centre at the University Of Exeter and the premises of an Independent laboratory in Ireland.  Longitudinal studies are ongoing and the coordinator also has a number of units in tests which focus on different types of source water and other potential challenges such as climate.
  • Certification efforts were impacted by the delay in finalising the machine design. Preparatory work was completed with a view to being prepared for the finalisation of the design. Testing has commenced with each of the relevant bodies - KIWA (European certification) WRAS (UK approval) ACS (French certification) NSF61 (US/global markets) and Watermark (Australian certification) The last of these is expected to be completed by mid-July.
