“…EDPr events may lead, for example, to floods and mudslides. As a consequence of these events, technical failures and disasters may occur, which in turn often give rise to big losses for society and the economy [9,12,17,20,31,37,38]. Scientific reports show an increased risk caused by extreme meteorological phenomena in recent years in different regions of the world, including intense precipitation [13,15,21,39,42].…”

“…Estimation of the number of extreme daily precipitation events is of great importance for prevention and management of floods, design of hydraulic structures (e.g., dams, spillways, and embankments) and municipal sewage systems [9,17,20,31,37,38]. EDPr may also play a significant role in the occurrence of other natural hazards, e.g., hydric erosion caused by storm precipitation, which may increase in Europe by 18% by 2050, landslides, and mudslides [39].…”

Extreme precipitation of a minimum daily value of >30 mm often initiates natural hazards such as floods, which in turn may not only lead to property damage but also present a danger to people’s health and lives. This paper mainly focuses on examining the trends and frequency of extreme daily precipitation (EDPr) in Poland. Also, it determines natural risk zones caused by EDPr of >30 mm, >50 mm, >70 mm, and >100 mm. In Poland, a significant positive trend was found for EDPr > 30 mm, >50 mm, and >70 mm in September, and for EDPr >100 mm in May. The most frequently recorded EDPr in Poland was >30 mm, the frequency of which ranged from 0.04% in February to nearly 3% in July. EDPr of >100 mm was recorded in 4 months, from May to August. An increase in the frequency of monthly EDPr in Poland occurred mainly in the southwestern and western parts. In Poland, three hazard zones of various frequencies of EDPr events were determined. In Zone III, which is in the southwestern and southern parts of the country, EDPr events occurred far more often than in Zone I; on average, four times more in the spring–summer season and slightly more than five times more in the autumn–winter season. The obtained results may help in the building of modern management and monitoring systems for the prevention of natural hazards caused by extreme precipitation.

“…The water supply and sewerage industry is sensitive primarily to heavy rainfalls and periods of high and low temperatures. During days with a high rainfall intensity, the phenomenon of the hydraulic overload of the rainwater drainage system occurs and may cause sewer flooding, resulting in flooding streets and basements, land flooding, or stormwater discharges in the case of combined sewerage [88]. On hot days, the water demand increases significantly (over the capacity of water intakes), and on frost days, the risk of failure of water pipes grows [89][90][91].…”

The weather derivatives market as an instrument of effective weather risk management is still not flexible enough for many industries. The water supply and sewerage industry is sensitive primarily to heavy rainfalls and periods of high and low temperatures: days with heavy rainfall may cause a hydraulic overload of the sewerage systems; on hot days, the water demand increases significantly; on frost days, the risk of water pipe failure grows. The work aimed to summarise methods of weather risk management and propose indices that will help to protect the interests of the water supply and sewerage industry in Poland. Three indices were proposed: a daily precipitation index, frost day index, and hot day index. The frequency of reaching these indices in Poland was verified with the use of meteorological data from 1970–2019, for 19 locations. The non-parametric Mann-Kendall test was used to determine the climate change impact on the exceedance frequency of the proposed indicators. The results showed that the indexes were exceeded in the past once every 6 years, on average. The hot day index was exceeded the least often, but it was the only one with a clear (growing) trend observed.
