Project Overview
We were commissioned to upgrade the water infrastructure at ATL Turbine Services in Dundee, addressing compliance issues and inefficiencies in their existing system. The project involved installing a 3,000L sectional GRP water tank and a Grundfos triple booster pump set to improve water supply reliability and meet Scottish Water byelaws.
Challenges Identified
- The site had an oversized 24,000L cold water storage tank, originally designed for fire suppression, but was now unnecessary due to the removal of all fire hose reels.
- The tank’s incorrect piping setup (inlet and outlet on the same side) prevented proper throughflow, leading to stagnation risks.
- Compliance concerns due to the lack of a suitable AB air gap required by Scottish Water regulations.
Solution Implemented
- Category 5 GRP Water Tank – Installed to provide the necessary AB air gap, ensuring full compliance with Scottish Water byelaws.
- Grundfos Triple Booster Pump Set – A new high-output, 3-phase Grundfos system was installed, featuring a standby/backup pump to maintain a continuous water supply in case of pump downtime.
- Inlet Float Valve – A 2” Keraflo KAX type valve was installed to regulate water flow from the 63mm incoming main.
- High-Quality Pipework & Insulation – The system was piped in 54mm press-fit copper with foil-faced mineral wool insulation for thermal efficiency and durability.
- Zero Downtime for the Client – All final connections were completed over the weekend, ensuring no disruption to factory operations.
Outcome
The new system provides a reliable, compliant, and energy-efficient water supply, eliminating previous stagnation issues and improving operational resilience for ATL Turbine Services.
