Municipal water and sewage utility serving Warsaw's 1M+ residents
Warsaw Waterworks operates Poland's largest urban water and wastewater infrastructure, moving 346M liters daily across 9,000+ km of pipe network. The tech stack is deterministic and legacy-heavy—Windows, Office, AutoCAD, SCADA, PLC, CCTV—reflecting the capital-intensive, mission-critical nature of utility ops. Recent hiring velocity is accelerating, with ops and security roles dominating 63% of open reqs, signaling active focus on network management and cyber-resilience for critical infrastructure.
Wodociągi Warszawskie (Warsaw Waterworks) is a publicly owned utility company chartered by Warsaw's municipal government to supply water and handle sewage treatment and disposal for the Warsaw metropolitan area. The organization operates over 4,500 km of water mains and an equal length of sewage networks, processing 346M liters of daily water supply and 512M liters of daily sewage discharge. Core infrastructure includes the Filter Station (a pre-war asset), modern treatment plants, and the Czajka sewage treatment facility (Poland's largest). The company balances 137 years of legacy engineering with modern technologies, including renewable energy investments and low-emission fleet development.
Windows, Linux, Microsoft Office (Excel, Word, PowerPoint), AutoCAD, SCADA, PLC, and CCTV systems. The stack is industrial/operational rather than software-development focused, typical of critical infrastructure utilities.
Active projects include hydraulic modeling and network optimization, cybersecurity improvements, payroll system implementation, and tariff approval processes. Pain points center on ISO 45001 compliance, incident response, fire safety regulation enforcement, and environmental monitoring.
