Hydrionis Data

France Water Service Performance Dataset

Annual water and sanitation service performance for French departments and France from 2008: all-in price per cubic metre, distribution network efficiency, linear leakage index, drinking-water compliance, unplanned interruption rate and mains renewal rate, from the SISPEA observatory. Reported as the median of what a typical service returns, with the number of services behind every figure published alongside.

What this looks like

One real series from the dataset, and real rows from the head of its published extract. Neither is a mock-up: the rows below are the same rows, unchanged, that are in the file you would download.

All-in water and sanitation price per cubic metre at France

The longest single series this dataset holds — 12 annual values, one of 783. The dataset is not this chart.

Drawn to show the shape and resolution of what the dataset contains, not to make a point about France. Gaps are breaks, never interpolated.

Methodology

Aggregated by Hydrionis from the statutory annual returns of individual French water services. Each figure is the median across the services that reported that indicator, computed only where at least three did. A median rather than a mean because these distributions have long tails and a mean would track a handful of outliers rather than the typical service. Unweighted, because the SISPEA served-population field is empty on every record the API returns: rather than weight by a proxy and call the result population-weighted, Hydrionis aggregates without a weight and says so. The count of services reporting is published as its own series, so the basis of every median is visible as data rather than asserted in prose.

What this dataset cannot tell you

Read before relying on these figures

A median over the services that made a return, not a population-weighted average and not a census. It answers "what does a typical French water service report", which is not the same question as "what does a typical French household experience": a department of many small rural services and one large urban one is described mostly by the small ones.
SISPEA response is voluntary in practice and varies by year. The services-reporting series must be read alongside the indicators to know how much of a department each figure describes.
These indicators are defined by French regulation and are not interchangeable with the English and Welsh measures of the same concepts. Network efficiency and the linear leakage index in particular are computed under different rules from the Ofwat leakage measures and must never be benchmarked against them.
A service spanning several departments is attributed to the department of its first commune rather than split, because the publisher does not provide a split and inventing one would fabricate a number.
The observatory has not released returns after 2019 through this API, so the series end there.

Suggested citation for Hydrionis

Hydrionis (2026), France Water Service Performance Dataset, version 1.0.0, accessed 2026-10-05, hydrionis.com/data/datasets/france-water-service-performance/

Cite Hydrionis where you rely on the compilation, the normalisation, the eligibility judgements or a chart. Where you use an unmodified published value, the publisher’s attribution is the one that is required; crediting Hydrionis as well is welcome and is not something Hydrionis can require of you.

Recommended, not required. Hydrionis does not claim rights over unmodified public data it relayed, and doing arithmetic on somebody else’s measurements does not make them Hydrionis’s. Cite the version and the access date: France Water Service Performance Dataset changes as publishers release and as methods are revised, and a citation without both cannot be checked later. Full guidance is on cite and reuse.

About this data

Everything below is a property of the data rather than a rating of it. There is deliberately no single confidence score: how much a gap matters depends on what you are about to do with the series, and only you know that.
