Innovation Manager
Severn Trent Model AreasTrimpley and Spernal
• Trial and demonstrate new technologies and ways of working.
• Pursue integrated management, control and automation.
• Deliver more resilient, calmer networks and enhanced customer performance.
• Develop the Effluent and Water Factory and Smart Network thinking - connecting our infra and non-infra assets.
Innovate – Integrate – Replicate
Spernal Catchment
Inputs
• Domestic Population ≈ 92000
• Trade effluent
• 34 consents (metal finishing, food processing & leachate)
• Dry Weather Flow Components
• 95% Domestic, 4% Trade, 1% Infiltration
Assets
• 575km of sewers - 3.25km of rising mains
• 16 pumping stations
• 5 CSOs
• 1 Siphon
Building on the Factory Concept
The Factory will automate the treatment process to match demand within the local network.
