This document is applicable to ozone used for treatment of water intended for human consumption. It describes the characteristics of ozone, specifies tests methods for determining the ozone concentration in gases and determines rules for safe handling of the chemical ozone.

This document specifies and gives guidance on: - general requirements for storage of water outside consumers' buildings, including service reservoirs for potable water and reservoirs containing water not for human consumption at intake works or within treatment works, excluding those that are part of the treatment process; - design; - general requirements for product standards; - requirements for, quality control and auditing, testing and commissioning; - operational requirements; - requirements for inspection, rehabilitation and repair. The requirements of this document are applicable to: - the design and construction of new reservoirs; - the extension and modification of existing reservoirs; - significant rehabilitation of existing reservoirs. NOTE 1 It is not intended that existing reservoirs are to be altered to comply with this document, provided that there are no significant detrimental effects on water quality. NOTE 2 This document does not apply to reservoirs formed by the building of dams or the use of lakes for water storage purposes.

This document provides guidance on identifying and assessing impacts of climate change on wastewater systems and on developing strategies for the adaptation to these impacts. The assessment of the impacts is based on the assessment principles described in ISO 24566-1 Assessment Principles. This document also provides examples of some of the impacts of climate change on drinking water systems and of the responses that have been implemented by municipal water services or by the relevant jurisdiction (e.g., municipality or region served by the service). The examples of responses illustrate adaptation strategies that have been applied.

This document is applicable to ozone used for treatment of water intended for human consumption. It describes the characteristics of ozone, specifies tests methods for determining the ozone concentration in gases and determines rules for safe handling of the chemical ozone.

This document contains requirements for dosing systems for chlorine dioxide generation according to the chlorite-chlorine gas process, the chlorite-acid process and the chlorite-sodium peroxodisulphate process, which are used for the disinfection and oxidation of substances in water. The chlorine dioxide (ClO2) solution is produced on site (in situ) by automated mixing of chemical precursors. This document applies to the treatment of water for human consumption, rinsing water for filters for swimming and bathing pools as well as for other uses (e.g. cooling water, process water, etc.
