Esders GmbH

Night-time acoustic leak-noise corpus from wireless correlating noise loggers: qualified per-logger night noise measurements transmitted autonomously over mobile networks (roaming eSIM, best-network selection) to a central cloud server, where they are automatically cross-correlated against GIS pipe data — layout, material properties and diameters — to localise leaks. Each detection is followed by repair, often within 24 hours, producing a tightly coupled measure-detect-excavate-verify loop. Validated by a scientifically accompanied pilot at IWB, the public supplier for the canton of Basel-City. Notably the method targets quiet leaks that fixed-threshold alarm systems miss, so the corpus contains the hard, low-signal cases

Dataset card

Type: not stated
Format: Time-series acoustic recordings plus correlation outputs — nightly noise captures per logger with frequency content, paired correlation results with time synchronisation, delivered to a cloud server and rendered into network GIS views with pipe attributes; GIS layers are updatable through a Draw Pipe feature, so logger data and vector network data are joined
Volume: Est. nightly acoustic captures per logger across the installed base: each logger records during the night window and transmits daily, so 33 loggers in the documented pilot yield roughly 12,000 qualified captures a year, and a fleet in the hundreds of loggers yields hundreds of thousands annually with a multi-year retention window. Frequency-domain captures are byte-heavy, so the acoustic archive is measured in gigabytes to terabytes per deployment — substantial for a small installed base, and dense because it is nightly, continuous and paired with GIS attributes
Users: N/A — B2B instrumentation and cloud analytics sold to water suppliers; no registered-user base. Footprint is per-deployment: a documented 33-logger scientifically accompanied pilot at IWB in Basel-City plus commercial deployments across German-speaking utilities; with 77 employees at the parent, the installed base is material but not large-aggregator scale
History: 7 years
Update frequency: not stated
Growth: Active — the article promotes the system as an established product with repeated field proof, positions it explicitly against fixed-threshold competitor systems, and highlights flexible logger relocation plus a Draw Pipe GIS update capability, all indicating ongoing product development rather than a frozen catalogue line
Launched: ~2018-2019 for Enigma3m — the article (published May 2020) refers to the previous summer's drought stress test and cites 2018 training statistics while describing the system as already proven many times in practice, including a completed scientifically accompanied pilot, so the product was commercially mature before 2020
