As a Subsurface operation Glasgow Subway experiences water ingress into its Tunnels system that is managed by a water pumping system that consists of 21 separate Sump locations and 43 Pump sets spread across the Subway infrastructure. Installed within these Sumps are either 2 or 3 Pumps sets, dependent on the water flow that is managed at that location. All pump sets operate on Duty/Standby configuration with the duty alternating between each pump. The Sump Pump starter control arrangements have been installed in a ‘Direct on Line’ (DOL) configuration that is both energy inefficient and produces a high mechanical shock on the pump set itself.
SPT wishes to upgrade and modernise a number of these Pump sets to utilise Variable Speed Drive (VSD) Technology and to bring with it benefits of less mechanical wear through a ramped start up operation and also look to reduce where possible the speed of the pumps to harness Energy and Carbon emission reduction.
