Located in Temple, near Gorebridge, in Midlothian, Scotland, Rosebery Wastewater Treatment Works treats raw water sourced from Megget and Gladhouse Reservoirs.

In recent years, the facility had suffered a number of water quality incidents, including positive detections of cryptosporidium and so Scottish Water sanctioned the £15.5m project to address water quality issues, with ESD, their non-infrastructure alliance partner.

The existing Rosebery site is extremely constrained by existing assets and topography and this was exacerbated by the need to maintain operation at full output throughout the construction and commissioning phases.

ESD were able to demonstrate that the design optimisation from innovative use of digital delivery tools and clever hydraulic design achieved significant embodied carbon savings, as well as providing time-saving solutions by avoiding lengthy re-engineering processes due to clashes.
