vesijakelusta

Vesijakelusta refers to the system and processes used to convey potable water from treatment facilities to consumers through a network of pipes, pumps, storage and controls. Its primary goal is to ensure a safe, reliable water supply at adequate pressure and quality for households, institutions and industries. The system typically includes treatment plants upstream, pumping stations, storage reservoirs or elevated tanks, distribution mains, service lines to buildings, valves, hydrants, meters and control systems. Operation relies on hydraulic design, optimization of pressure zones, looped pipelines to improve reliability, and monitoring with SCADA systems, sensors and water meters to detect leaks and ensure water quality.

Key functions include maintaining quality by keeping residual disinfectant, preventing contamination through backflow prevention and cross-connection control, and enabling rapid isolation of faults. The network must adapt to demand patterns, seasonal variation and emergencies while minimizing non-revenue water caused by leaks and theft. Maintenance activities cover pipe renewal, leak repair, valve exercising and corrosion protection.

Regulation and planning involve water quality standards, regular sampling and analysis, safety protocols, asset management, and contingency planning for drought, flood or contamination events. Challenges include aging infrastructures, financial constraints, climate impacts, population growth, and cybersecurity risks to control systems. Vesijakelusta is typically operated by municipal or regional utilities, often coordinated with water treatment and distribution planning to provide safe drinking water and fire protection to the service area.
