In Nicaragua, Technical Standard No. NTON 11-051-19 approved on September 30, 2020, defines drinking water as that which fulfils quality standards for drinking water as described in the WHO Guidelines for Drinking Water Quality and stipulates that water for human consumption and handwashing of agricultural workers must be drinking water.

In Uruguay, UNIT Standard 833:2008 issued by the Uruguayan Institute of Technical Standards establishes a series of requirements that must be met in drinking water for human consumption, regardless of water collection point, treatment type, production and distribution system. The requirements were adopted through a review process essentially based on World Health Organization (WHO) Guidelines. Of the total parameters that have been standardized in the country, 13.04% are below the values defined by the WHO, 7.83% are above WHO values and 46.96% match WHO values, while the WHO does not have reference values for the remaining 32.17% of parameters.

In Kenya, standards are developed by the Kenya Bureau of Standards (KEBS). The role of the Water and Sanitation Regulatory Board (WASREB) is to enforce the following basic requirements for drinking water, that it is: free from pathogenic (disease causing) organisms; contains no chemicals that have adverse or long-term effects on human health; is fairly clear (i.e. low turbidity, little colour); is not saline (salty); contains no compounds that cause an offensive taste or smell; and does not causing an encrustation of the water supply system nor stains clothes washed in it.
