BQ - Achieving 100% compliance with drinking water standards at point of use by 2050? Taste and Odour: Methods of Detection

To provide the water industry with a quantitative method of measuring Taste and Odour

Problem

The taste & odour (T&O) of water supplied to customers affects their perception of the quality of that water. When Water Companies receive contacts from customers about T&O, it is often difficult to pin down the root cause and to rectify it. We need a better understanding of the causes of T&O and understand what causes the customer to react.

Customer sensitivity to T&O causing compounds varies widely, as it does for those investigating them. The current method of analysing T&O is qualitative and subjective; a taste panel based on a limited number of descriptors. At present, we only have analytical methods for a small proportion of T&O causing compounds.

Impact

Unless T&O can be accurately measured and understood the risk of performance commitment penalties increases. It also leads to reputational impacts and a high number of customer complaints. 

Project

This project forms part of UKWIR’s Big Question ‘How do we achieve 100% compliance with drinking water standards by 2050?’

 The project will improve our understanding of T&O by developing analytical methodologies and exploring the links between the molecular chemistry and the sensing that triggers customer contacts.

BQ How do we achieve 100% compliance with drinking water standards by 2050? Better understanding of the chemistry of the control of lead

To advance the water industry’s understanding of the chemistry that controls the solubility of lead and the conditions which influence the efficacy of phosphate in plumbosolvency control.

Problem

Much of the underlying work on lead compliance is based on an empirical understanding of the behaviour of lead compounds formed on the surface of pipes. This is the basis which the Industry uses to deploy high OPEX phosphate dosing and high CAPEX limited impact lead pipe replacement.  

The industry is now driving for compliance at a lower standard - 10µg/l and the DWI have commented that they are ‘minded to support’ an even lower 5µg/l standard in the future.

Impact

The key mitigations deployed to date have needed considerable capital or operational costs. The approach of phosphate dosing relies on very complex chemistry and the majority of research on this took place 15-30 years ago when the regulatory standard changed from 100µg/l to 50µg/l. It is not clear how we will meet the lower levels of compliance.

BQ02-E21- Transferring minimal excavation methods into the water industry

To assess the current methods of carrying out minimal excavation repairs, identify the issues in transferring these technologies into the water industry and develop both a routemap and a functional specification that will facilitate application for suitable innovation funding and the successful deployment of such products.
