Now in its 45th year and 14th version, WRc's TR61 is a powerful, integrated cost and carbon estimation tool. It is widely used to model water and wastewater assets across the UK water industry, and is certified for use in Periodic Review activities.
TR61, or 'Cost Information for Water Supply and Sewage Disposal' Technical Report 61, allows:
- up-to-date estimates of capital (CAPEX), operating (OPEX) and whole life costs; and
- estimates of embodied (building) and operational carbon emissions with their monetary equivalents in a manner consistent with Ofwat‟s requirements.
