Wannon Water

What Wannon Water does

Wannon Water is a Victorian government-owned regional urban water and sewerage corporation, established under the Water Act 1989 and headquartered in Warrnambool, Australia. It is described as Victoria's second largest regional urban water corporation and provides reticulated water treatment and sewage services to more than 30 communities across 24,000 square kilometres of South West Victoria, supplying more than 33 million litres of drinking water daily (nearly 12,000 megalitres annually) through nearly 2,000 kilometres of water mains and more than 1,000 kilometres of sewer mains. Its core service portfolio comprises water supply, sewerage (covering 16 towns with sewage treatment, recycled water, and biosolids processing for agricultural reuse), trade waste management, and property connection services; supporting these are digital self-service (myWannonWater online portal powered by Azure AD B2C), concession programs, hardship support, the Ripple Effect community grants program, Thirst Aid event water stations, and a structured Learning Centre for school education.

The company operates a diversified water source portfolio including the Otway supply system, Grampians supply system, the Dilwyn and Bridgewater Formation aquifers, surface catchments, and an award-winning roof water harvesting system. Notable infrastructure includes the Portland wind turbine (2020, first Australian city to achieve net zero-plus emissions at water/sewage facilities) and the Brierly Basin floating solar array (under construction, 500kW, ~AU$2M, partnership with Enervest, targeted to be Australia's largest upon completion in 2026).

Wannon Water operates as a not-for-profit monopoly utility under regulatory oversight from the Essential Services Commission, which approves prices generally effective 1 July each year. Its revenue model combines fixed service charges (~$192/year water service, ~$846/year sewerage service for homeowners) with variable usage charges ($1.761/kL, average customer uses 142 kL/year), billed quarterly, plus trade waste volume charges for commercial customers and concession discounts of 50% for eligible card holders. The customer base spans residential (homeowners and renters), rural, non-residential/business, trade waste, and local government segments, with no concentration in any single named account. GTM is sales-led but regulator-driven, with distribution through three physical offices (Warrnambool, Hamilton, Portland), the myWannonWater portal, phone support, and a community engagement platform (Engage & Explore).

Direct peers

• North East Water: Regional Victorian water corporation serving north-east Victoria. Closest peer in terms of regulatory framework, customer scale, and reliance on seasonal water sources; comparable drought-management profile and infrastructure footprint to Wannon Water.
• Coliban Water: Regional Victorian government-owned urban water corporation serving central and northern Victoria. Directly comparable as a similarly-sized regulated water and sewerage provider outside Melbourne, with comparable customer mix, pricing approval via the Essential Services Commission, and a multi-source supply strategy.
• Goulburn Valley Water: Regional Victorian water corporation serving the Goulburn Valley. Comparable as a state-owned regional water utility operating under the Water Act 1989 with similar service scope (potable water, sewerage, trade waste) and pricing oversight by the Essential Services Commission.
• Lower Murray Water: Regional Victorian water corporation serving the state's north-west. Comparable as a similarly-sized rural/regional water utility exposed to irrigation customers, drought conditions, and highly seasonal demand — directly relevant to Wannon Water's rural customer segment and water security planning.
• East Gippsland Water: Regional Victorian water corporation serving East Gippsland. Comparable in scale and in the mix of small-town potable water supply and sewerage services across a wide geographic area, with similar regulatory and pricing dynamics to Wannon Water.

Broad incumbents

• Sydney Water: NSW state-owned water and wastewater utility serving Greater Sydney. Provides a read-across for net-zero roadmaps, recycled water programs, and Indigenous/community engagement initiatives at the scale a regional Victorian utility could aspire to.
• Melbourne Water: Bulk water supplier and major drainage operator for Greater Melbourne. Comparable as the upper-catchment and waterway-management counterpart to Wannon Water's role in South West Victoria, sharing the same state-government oversight and environmental management mandate.
• South East Water: Large Melbourne metropolitan water utility with broader product breadth (recycled water, large-scale trade waste, smart metering). Provides read-across for how Wannon Water's customer service and digital (myWannonWater) capabilities could evolve at regional scale.
• Yarra Valley Water: Melbourne's largest water utility by customer base. Acts as a broader-incumbent reference point: an established state-owned utility operating diversified water, sewerage and recycled water services with mature community engagement programs.

Others

• Enervest: Australian renewable energy developer partnering with Wannon Water on the AU$2M Brierly Basin floating solar project. Comparable as a strategic infrastructure and ESG partner rather than a direct competitor, but relevant to understanding Wannon Water's pathway to its net-zero 2030 commitment.
