Industry overview
The Sewerage sector across Belgium comprises approximately 220 enterprises employing about 2,890 people and generating โฌ1.4 bn in net turnover in 2020. The average enterprise size is โ employees per firm. This is a useful yardstick when assessing whether your own operation sits within the typical scale band of the sector.
Profitability
With a robust operating margin of 38.2% of revenue in 2020, the sector reports โฌ541 M of gross operating surplus (Eurostat's EBITDA-equivalent, before depreciation). This figure provides the headline benchmark against which an individual operator can sanity-check their own bottom line, values significantly below indicate cost or pricing pressure, those above suggest competitive advantage worth defending.
Cost structure
The Sewerage cost mix is reasonably balanced: cost of revenue at 47.8%, personnel at 14.6% and energy at โ of turnover. Without a single dominant cost driver, margin management requires attention across the full operating envelope rather than focus on any one line.
Trend & trajectory
Over the period 2008 to 2020 the operating margin moved from 34.3% to 38.2% (+3.8 percentage points), an encouraging upward trajectory. Sectors with stable or improving margins tend to reflect successful pass-through of input costs and disciplined capacity management; declining margins typically point to either over-supply or a structural cost squeeze that warrants strategic review.
