Bonnycraig Water Treatment Works, Scotland

Scottish Water (SW) selected PWNT’s CeraMac® filtration and Inline Coagulation and Adsorption (ILCA®) technologies for the construction of its new-build water treatment plant at Peebles, Scotland. The new plant replaces an existing installation dating from 1970 and became operational in December 2022.

The decision to use PWNT’s technologies at Bonnycraig was made after a series of successful pilots in Invercannie (2017), Turriff (2018), and Marchbank/Bonnycraig (2019/20) in line with two key principles: a plant that would be sustainable, and the minimisation of landscape impact.

Consisting of four C-19 CeraMac® vessels and four ILCA® 270 vessels, the plant using feedwater from Megget Reservoir is expected to produce 4 MLD, and shall be constructed relying on the Transportable Treatment Units developed by Ross Shire Engineering (RSE). RSE’s modular units, complete with PWNT equipment, will be fabricated and assembled in RSE’s Muir of Ord workshops, prior to being transferred to site at Bonnycraig WTW, Peebles. Transporting the completed unit direct to site will overall reduce the MEICA and civil construction impact on the local community and wider environment.
