DEVICE FOR INCREASING PRESSURE IN WATER SUPPLY SYSTEMS WITH MEASUREMENT OF ACCUMULATED DRINKING WATER QUALITY

Abstract

Low pressure in water supply systems, affecting both residential and industrial facilities, is a common issue in water distribution networks. Water sourced from municipal systems or shallow wells can experience pressure fluctuations or even complete drops, particularly during summer months. Supply from rooftop or overflow reservoirs often fails to maintain sufficient pressure to adequately supply all taps and appliances. Low pressure can also disrupt household devices such as washing machines, dishwashers, and water heaters. To address these problems, pressure-boosting systems are installed, which include additional pumps connected inline with pipelines or accumulation tanks for cases when water supply is interrupted. +The simplest solutions involve hydrophore units (a booster pump combined with a pressure vessel controlled by a pressure switch). However, noise generated by water pipes or booster pumps can cause discomfort for residents, often due to improper pump selection or inadequate regulation. Older centrifugal pumps with fan-cooled motors can create system-wide vibrations, increasing overall noise levels. This paper presents a technical solution for a pressure-boosting device in water supply systems, featuring reservoirs, recirculation pumps, water quality measurement systems, pressure-increasing pumps with PID control, compact electronic pressure transmitters, and expansion tanks. The design ensures silent operation while maintaining constant pressure in the water supply network. The device has been installed and tested in the Tonanti Hotel, Vrnjačka Banja, Serbia.
