CP520  Cost Effective On-line Turbidity Monitoring Monitoring

Many adverse customer contacts could be avoided by better management of turbidity in the water distribution network but recent research by WRc into on-line monitoring of water quality in distribution has identified that no current commercial instrument meets the market need.

This is particularly true for turbidity where the main user requirement is for better than 6 month maintenance, accurate and reliable readings, ease of entry and retrieval in different size mains. However suppliers tend to include turbidity as one parameter on a multi-parameter platform which means that maintenance is too frequent and the annual cost of ownership is generally above the value of the data produced.

The objective of this project is to develop a new turbidity-only instrument for direct insertion into a main, with a long maintenance interval at an affordable whole-life cost and to do this in close collaboration with end-users.

BUSINESS BENEFITS TO CLIENTS

  • Cost effective on-line monitoring of turbidity to better manage discoloration and reduce negative customer contacts.
  • Potential income stream through the license agreement.

WORK PROGRAMME

The development programme will be carried out in stages with a decision point at the end of Stage 1

Stage 1 - 6 months

  1. Develop user specification and develop design ideas using Oxford University as consultants.
  2. Carry out feasibility study of options using modelling and laboratory testing.
  3. Protect IP, produce recommendations for a prototype design and apply for Knowledge Transfer Partnership (KTP).

Stage 2 - 14 months

Stage 2 will build and test prototypes for laboratory and field testing, supported by KTP with Oxford University to bring in additional expertise.

PROJECT OUTPUT AND IMPLEMENTATION

Stage 1 - a detailed specification and outline design of the selected option(s), application for KTP and a costed proposal for Stage 2.

Stage 2 - fully working prototype, license agreement with commercialisation partner and agreement for implementation of the first production units.
