'New reservoirs will help address water shortage'

Essex & Suffolk Water has launched the Suffolk Water Recycling, Transfer and Storage Project as part of a wider £1.5bn regional investment to bolster long-term supply in a county designated by the Environment Agency as Seriously Water Stressed. The plan would add an 11 million-litre-per-day purified water recycling plant near Lowestoft, two partly buried reservoirs (near Sibton and Eye airfield), and roughly 50 miles of pipelines to serve about 1.8 million households and enable additional commercial connections; initial public consultation attracted ~1,000 participants and feedback was broadly supportive.

Analysis

Market structure: The Suffolk scheme crystallises winners as regulated water utilities and large infrastructure contractors — firms able to capture regulated asset base (RAB) growth (e.g., Severn Trent SVT.L, United Utilities UU.L, Pennon PNN.L) and contractors with civils capabilities (Balfour Beatty BBY.L). Pricing power for utilities is steady but capped by regulators (Ofwat); incremental supply from reservoirs/recycling reduces local scarcity premium and lowers the probability of demand curtailment in East Anglia over 3–10 years. The £1.5bn regional pipeline implies meaningful mid-capex procurement (hundreds of millions) for contractors and supply chains over 2–5 years.

Key Decisions for Investors

• Establish a 3% portfolio long in Severn Trent (SVT.L) over a 6–18 month horizon; target 8–15% total return if Ofwat approves cost recovery; trim if 12-month TSR exceeds 15% or if disclosed capex overruns exceed 30%.
• Add a 2% long position in United Utilities (UU.L) as defensive regulated exposure; increase to 4% if Ofwat issues positive direction on cost recovery or incentives for water-stressed regions within 6 months.
• Buy a 12-month call-spread on SVT.L (buy ATM call, sell +15% strike) to capture upside with limited premium; position size capped to 0.5–1% portfolio risk and reassess after contract awards or planning approvals (expected within 6–12 months).
• Allocate 3% to Invesco Water Resources ETF (PHO) for diversified global water infrastructure exposure; rebalance if the ETF outperforms FTSE All-Share by >5% in any 3-month window.
• Purchase £10k–£20k equivalent of 7–12yr UK utility green bonds (Severn Trent/United Utilities) if spread to UK Gilts is ≤150bps; do not buy if spread >250bps or if base rates rise >100bps in the next 6 months.
