Abwasserbetrieb Troisdorf AöR

What Abwasserbetrieb Troisdorf AöR does

Abwasserbetrieb Troisdorf AöR is a municipal wastewater utility (Anstalt des öffentlichen Rechts) established in 1969 and owned by the City of Troisdorf in North Rhine-Westphalia, Germany. The company is the statutorily mandated provider of public wastewater collection, treatment, and drainage services across the city, operating the Kläranlage Müllekoven — a mechanical-biological treatment plant with 84,000 Einwohnerwerte design capacity — together with approximately 400 km of public canal network (274 km mixed-water, 33 km wastewater-only, 43 km rainwater), 42 pump stations, and 8 stormwater overflow basins. Beyond core wastewater services, the utility operates the city's street lighting network (currently undergoing phased LED modernization under the National Climate Protection Initiative), maintains multiple local watercourses (Mühlengraben, Asselbach, Scheuerbach, etc.), and provides property drainage services including connection, condition testing (Kanal-TÜV), and backflow protection for ~17,000 connected properties achieving a 99.9% connection rate.

The business model is entirely fee-based and statutorily cost-covering: regulated wastewater fees (€4.19/m³ for conveyance and treatment; €1.22/m³ for conveyance only), Niederschlagswassergebühren (rainwater fees at €1.88/m²), Straßenentwässerungsgebühren (street drainage at €1.94/m²), discharge fees for groundwater and cooling water (€2.71/m³), sludge disposal fees (€19.41/m³), and one-time Kanalanschlussbeitrag contributions for new connections (€4.20–€5.71/m²). Distribution is exclusively direct via a customer service office at Poststraße 105, dedicated billing and property-drainage phone lines, a 24/7 emergency hotline, and an online self-service portal covering area declarations, meter registration, inspection uploads, and SEPA mandates.

Digital differentiation includes the Starkregengefahrenkarten (interactive heavy rain hazard maps built on a 1x1 m digital terrain model across three rainfall scenarios), the Wasser-Risiko-Check (a 30-question property flood risk tool co-developed with StEB Köln, launched August 2023), and the Digitale Netzplanauskunft online infrastructure map. Sustainability initiatives include four photovoltaic installations, biogas cogeneration, and biodiversity programs on ~9,000 m² of green space. The utility co-founded KLAR GmbH (Klärschlammverwertung am Rhein) in July 2022 with StEB Köln, Stadtwerke Köln, Bundesstadt Bonn, and KKP to build a regional sludge incineration facility with phosphorus recovery in Köln-Merkenich, planned for operations start in 2029 under new federal sludge regulations.
