This week in Riga there will be flushing of the main water pipe from the turn to Langstiņi (Vidzeme highway) to the water preparation station "Zaķumuiža". Works are planned for three days – from Tuesday, October 20, 8.00 to Friday, October 23, 8.00. During rinsing, water fouling may occur in Jugla, Teika and Čiekurkalns.
The purpose of preventive flushing of water pipes is to maintain a consistently high quality of drinking water and ensure a stable water supply, preventing the accumulation of deposits in the system. In total, Rīgas ūdens had planned to flush 360 km of water pipes this year, which has already been done, but the weather conditions currently allow these works to continue.
During flushing works, temporary interruptions of water supply are expected for certain buildings:
‘Indās’, Makstenieki;
If the required water quality is achieved faster as a result of flushing the water pipe, the works will be completed before the specified time. After rinsing work in these areas, the water may be saturated with air, which visually makes it white, but is absolutely safe for use and not harmful to health.
During flushing, the accumulated deposits – iron and mineral particles – are flushed out of the pipes with an increased water flow rate and air, which helps reduce water turbidity, improve water color and taste.
Based on a study carried out in cooperation with Riga Technical University, Rīgas ūdens has developed a long-term flushing plan for water mains networks. This allows for the prioritisation of the flushing sequence of the nearly 1 550 km long water mains network, with flushing of the mains and distribution water mains networks at least every five years.
