Project Description

Water Technology R&D Tax Credit



Re-Water Corporation provides consultation, design, construction, and process optimization to the water and waste-water industry. The organization now provides recycled-water validation services for new and existing water-reuse schemes.

In 2013, Re-Water began a project with the main objective being to design and develop a water-quality system to detect contaminated storm water and prevent spillage and flow offsite. Specific technical objectives of developing the water-quality system included:

  • Design and develop analytical sensors to monitor, detect and extract data related to the chemical properties of contamination’s in waste-water streams—the focus will be mainly on storm water.
  • Develop a human machine interface (HMI) and control parameters to control the hardware components of the system—this needed to also allow users to switch between various screens related to equipment setup and the various accessing of data logging.
  • Design and develop programmable logic controller (PLC) as part of control parameters.
  • Develop the programmable coding for the PLC, which can be manipulated by users depending on site requirements and water data–monitoring requirements.
  • Design and develop hydraulics.
  • Design and develop electrical components—to be low voltage across various circuit boards.

Re-Water needed to determine the eligibility of its proposed R&D activities  in order to know if they qualified for R&D Tax Relief Schemes. It had to be certain that its qualified research met key legislative requirements within the tax definition to demonstrate the project is R&D. These requirements include defining for tax purposes:

  • Project
  • Advance in science or technology
  • science
  • technology
  • directly contribute
  • scientific or technological uncertainty


Background research to evaluate current knowledge gaps and determine feasibility (background research of the water-quality plant system). 

Background research for Re-Water’s R&D water technology credit included the following:

  • Literature search and review.
  • Market analysis and review, including competing products, bench marking of best available solutions.
  • Consultation with industry professionals and potential customers to determine the level of interest and commercial feasibility of such a project.
  • Preliminary equipment and resources review with respect to capacity, performance and suitability for the project.
  • Consultation with key component/part/assembly suppliers to determine the factors they consider important in the design, and to gain an understanding of how the design needs to be structured accordingly.

Design and development of a series of prototypes to achieve the technical objectives (design of the water-quality plant system). 

The hypothesis for the design phase of Re-Water’s project was designing a water-quality system with improved hydraulics, user-friendly PLC, and seven analytical sensors will produce a system that more accurately detects the contamination substances (type and chemical properties) in storm water and, therefore, allow operators to prevent spillage and flow offsite.

Major changes to the design of the plant/system and its components resulted from the finding that the organization could use the information generated in the water samples taken to conduct various other activities. Re-Water designed many versions of components and the overall system as a whole to avoid potential technical issues in the development phase; however, to prove that its theoretical concepts can operate in the intended application, it needed to develop and construct prototypes for chemical testing.

Trials and analysis of data to achieve results that can be reproduced to a satisfactory standard and to test the hypothesis (prototype development and testing of the water-quality plant system). 

The hypothesis for this stage of the R&D project was the same as the design phase. The following activities were conducted to prove the hypothesis:

  • Development of a prototype and manufacturing was conducted by an external manufacturer
  • Development of the HMI and control parameters
  • The sensors  on the prototype were found to have made more sense (regarding the data obtained) when combined as opposed to when they were operating independent of each other. That is, they provide clearer indication about contamination physical properties and chemical values, which therefore allows Re-Water to more accurately identify the type of contamination within the storm water.

Ongoing analysis of customer or user feedback to improve the prototype design (feedback R&D of the water-quality system). 

The feedback was necessary to evaluate the performance capabilities of the new design in the field and to improve any flaws in the design. The feedback activities included:

  • Ongoing analysis and testing to improve the efficiency and safety of the project.
  • Ongoing development and modification to interpret the experimental results, and draw conclusions that serve as starting points for the development of new hypotheses.
  • Commercial analysis and functionality review.



Qualified R&D projects consists of research for the intent of achieving an advance in overall knowledge. Advances in capabilities in the field of science or technology through the resolution of scientific process or technological uncertainty general qualify as R&D project. The advancement but not simply be in its own state of knowledge or capability. A companies R&D project must relate to the trade of the business whether it be an existing product or process or one intend to start based on R&D outcomes.


Activities that are eligible for R&D Relief are defined in the Guidelines by the HMRC, which must be met for the project to qualify as R&D.

  1. Project
  2. Advance in science or technology
  3. Science
  4. Technology
  5. Directly contribute
  6. Scientific or technological uncertainty


Similar to any tax relief, Re-Water had to save business records that outlined what it did in its R&D water technology activities, including experimental activities and documents to prove that the work took place in a systematic manner. Re-Water saved the following documentation:

  • Project records/ lab notes
  • Conceptual sketches
  • Design drawings
  • Literature review
  • Background research
  • Design documents for system architecture and source code
  • Testing protocols
  • Results of records of analysis from testing/trial runs
  • Records of resource allocation/usage logs
  • Staff time sheets
  • Tax invoices
  • Patent application number

By having these records on file, Re-Water confirmed that it was “compliance ready” — meaning if it was audited by the HMRC, it could present documentation to show the progression of its R&D work, ultimately proving its R&D eligibility.
