Project Appreciation and Objectives
Service pipe data held by Water Utilities are generally incomplete and of poor quality. Details such as exact location, construction material, diameter and age of these assets are not usually available. There are also concerns over service pipe ownership and whether Utilities will be expected to adopt supply pipes and maintain them in the future. This places Water Utilities at an immediate disadvantage in day-to-day operations and in understanding the impact of any changes to the current ownership / responsibility model.
Two issues that present immediate concern are the:
- Requirement to reduce the maximum allowable concentration (PCV) of lead in drinking water at consumers taps from 25 µg/l to 10 µg/l by 25 December 2013. This will be achieved by water treatment and a targeted lead pipe replacement programme.
- Need to reduce leakage from water supply pipes - considered to be one of the last areas where a significant reduction in leakage could still be made.
This project will improve the data gathering process for service pipe interventions, particularly lead pipe replacement and supply pipe leakage strategies, to support cost-effective network management. Existing working practices will be analysed to identify opportunities for improving data capture. Technological solutions for recording data in the field will be trialled in order to identify the most appropriate solutions for filling the data gaps.
