CP503  Increased Compliance Through Effective Lead Indicators Asset Management
Project Appreciation and Objectives

The correct selection and use of lead indicators in water and wastewater treatment provides forewarning of asset or compliance failure. Depending upon the timescale of interest, lead indicators can provide information to:

  1. operations, to prevent asset/compliance failure (short-term benefit);
  2. planning and strategy teams, to determine the most cost-effective measures to intervene to minimise risk of service failure (medium or long-term benefit).

In order to understand the probability of asset failure (and the subsequent consequences of failure on customer service), there is a need to monitor lead indicators in real time so that resources can be allocated effectively to mitigate such risks and avoid unwanted failures.

In addition, lead indicators provide an effective means of monitoring process 'drift', long before any failure or compliance issue occurs, to highlight sub-optimal process efficiency.

The objective is develop or identify suitable lead indicators that can be used by companies to enhance the effectiveness of monitoring and auditing of water treatment and wastewater treatment assets to optimise operation and improve compliance; and offer confidential company-specific recommendations for improvements to current practice where required.

Business Benefits to Clients

  • Mitigated and reduced operational failure risks.
  • Effective allocation of resources on developing operational issues.
  • Improved practice in performance management across water and wastewater treatment functions.

Work Programme

  1. Identify current industry practices in performance management of water and wastewater treatment facilities, in particular the use of indicators for early warning of compliance or process efficiency issues. Cross reference to out-of-sector practices (e.g. chemical processing)
  2. Review practices relating to the use of lead indicators for treatment process performance management and, building upon relevant research, develop good practice guidance.
  3. Benchmark company practices against good practice and make company-specific confidential recommendations.

Project Output and Implementation

  • Good Practice Guide for performance management of water and wastewater treatment assets through the adoption and use of lead indicators.
  • A confidential company-specific report which makes recommendations for migration from current practice to good practice, as required.

Related WRc Work

  • Strategic review of forward-looking indicators for treatment assets for a large water and sewerage company.
  • Multiple projects to implement water and wastewater treatment monitoring and control strategies for individual water utility clients.
  • Work on behalf of UKWIR on the application of Statistical Process Control (SPC) in water treatment for managing cryptosporidium risk, and evaluating process-based control as a management and regulatory tool for the water sector.
