Work Description & Methodology

The upgrade required sophisticated live flow management to prevent service outages. SNG’s methodology involved the construction of a new penstock chamber and the integration of modern mechanical systems into legacy structures. The electrical component involved replacing outdated switchboards with new units featuring PLC/SCADA logic, enabling remote flow monitoring and reducing the frequency of on-site manual inspections.
