Water Treatment and Infrastructure
We specialise in civil engineering solutions for the built environment, including designing, constructing, and maintaining essential water infrastructure. Our expertise encompasses Controlled Sewer Overflows (CSOs), sewage and wastewater systems (including sewers, treatment plants, shafts, tanks, and pumping stations). We handle everything from minor repairs and pipe replacements to the installation of completely new water systems, ensuring efficient and safe operation.

Transportation washing facilities
Routine train presentation is essential to uphold clean rolling stock and upkeep maintenance. Washing facilities such as carriage washes and hand washing spaces provide safe, accessible spaces to carry out duties
Cairn Cross has installed many carriage wash facilities, including the associated civils for drainage, connecting to existing infrastructure, potable water and pollution control.
