The problem of water renewal in swimming pools is mainly related to the concentration of some contaminants (with the quality of swimming pool water) and to the need for water to supplement losses in the closed swimming pool circuit (volume of swimming pool water). This problem is presented on the basis of physicochemical analysis of pool water samples (taken every two hours during one day and taken daily during one week) and the amount of supplementary water demand (water metre reading) depending on attendance and in relation to rational water management for a sports-type pool. The results were compared with the guidelines of the Swimming Pool Water Quality Decree and the recommendations of DIN 19643. Pool water quality parameters, such as: absorbance, redox potential, combined chlorine, nitrates, and chlorides, could be considered as indicative for the daily assessment of water, and depending on their value, supplement the circuit with water from the water supply network. The amount of supplementary water used (an average of 40.6 L/bather day) exceeded the DIN 19643 recommendations by 26%. To rationalise water management, a water quality analysis should be carried out with the consumption of supplementary water reduced to 30 L/bather day (that is, on average 11.5 m³/day instead of 15.6 m³/day).

Problem odnowy wody w obiektach basenowych związany jest przede wszystkim z zatężaniem niektórych zanieczyszczeń (z jakością wody basenowej) oraz z zapotrzebowaniem na wodę uzupełniającą straty w zamkniętym obiegu basenowym (objętością wody basenowej). Problem ten przedstawiono na podstawie analizy fizykochemicznej próbek wody basenowej (pobranych co dwie godziny w ciągu jednego dnia oraz pobranych codziennie w ciągu jednego tygodnia) i wielkości zapotrzebowania na wodę uzupełniającą (rejestr wskazań z wodomierza) w zależności od frekwencji oraz w odniesieniu do racjonalnej gospodarki wodnej dla basenu typu sportowego. Wyniki porównano z wytycznymi rozporządzenia w sprawie jakości wody w pływalniach oraz zaleceniami normy DIN 19643. Parametry jakości wody basenowej, takie jak: absorbancja, potencjał redox, chlor związany, azotany i chlorki, można było uznać za wskaźnikowe do codziennej oceny jej jakości i w zależności od ich wartości uzupełniać obieg wodą z sieci wodociągowej. Stosowana ilość wody uzupełniającej (średnio 40,6 L/os.·d) przekraczała zalecenia normy DIN 19643 o 26%. W celu racjonalizacji gospodarowania wodą należałoby przeprowadzać analizę jakości wody przy zmniejszonym do 30 dm³/os.·d zużyciu wody uzupełniającej (czyli średnio 11,5 m³/d zamiast 15,6 m³/d).
