The purpose of this project is to provide water companies with good practice guidance for the whole life management of the construction, refurbishment, repair, operation and maintenance of treated water storage assets. Such guidance is mapped to the UKWIR Framework for Expenditure Decision Making in order to help asset managers, operators and capital investment planners better inform investment decisions to manage water quality risks.

The project was developed in conjunction with significant industry engagement, through two industry workshops involving representatives from UK Water Companies, Regulators, Academia and Industry, and five water company interviews. 

The project deliverables consist of:

• a guidance document summarising good practices for the inspection, operation, maintenance, refurbishment, repair and new construction of treated water storage assets; and
• a complementary spreadsheet toolkit illustrating a process to support investment planning activities for treated water storage assets through a condition assessment, deterioration and risk modelling approach.
