This indicator calculates the pressure of all sectors in the country on renewable freshwater resources. The low level of pressure on the water resources indicates that the amount of water resources used by all sectors is small compared to existing resources and, therefore, has little potential for the sustainability or competition among users.

The high level of pressure on water resources indicates that the overall use of water in all sectors constitutes a considerable proportion of the total amount of renewable freshwater resources, which ultimately affects the sustainability of resources and causes potential conflict and competition among users can be.

The total amount of renewable freshwater reserves is the total amount of renewable domestic and external water resources. Here, "water resources" and "use of water" are meant to use freshwater resources and freshwater resources.

Renewable internal water resources are defined as the long-term annual average of the annual flow of rivers in a given country and the amount of re-feeding resulting from endogenous rainfall in underground waters.

Renewable offshore resources include water flows to the country. In this case, the amount of flows of the currents held for the countries located in the upper and lower streams is also taken into account in accordance with the contract or agreement.

The total volume of freshwater resources extracted from the source is the amount of fresh water taken from the source (river, lake, lake) for agricultural, industrial and household use. It is calculated nationally for the following three major sectors: agriculture, domestic use and industry. The first freshly taken fresh water from the source (not earlier than the source), the freshly taken fresh water (returned from the source and returned to rivers and groundwater) water - treated waste water and drainage water in agriculture) and groundwater. This includes non-traditional water, for example, direct use of treated wastewater, direct use of agricultural drainage water, and salt-free water. The total volume of freshwater resources extracted from the source is responsible for the direct use of waste water from the total water resources withdrawn from the source of the water resources, the direct use of agricultural drainage water and the removal of saline water.

The water demand for water is the amount of water required to maintain freshwater and excretory ecosystems. Water quality and ecosystem services are not included in this calculation. This calculation is limited to the volume of water. This does not mean that the support and quality of societies that depend on environmental flows are not crucial and should not be overlooked. The methods for calculating the water demand for water are extremely variable and vary from global estimates to complex reviews on river stripes. For the purposes of this SDG, the volume of water may be expressed by the same units as the total volume of freshwater resources extracted from the source, and then the percentage of existing water resources.

The State Statistical Committee implements the quality management system in accordance with the international standard ISO 9001. In 2013 the external audit of the quality management system was conducted in the State Statistical Committee, and in August of the same year for the first time ISO 9001:2008 international certificate of conformity was obtained in the direction of "Production and dissemination of official statistical data". After a major change of the international standard in 2015, all documents of the quality management system were redesigned in accordance with the requirements of the international standard ISO 9001:2015. According to the results of certification audit conducted on March 09-10, 2017, the apparatus of The State Statistical Committee and 13 local statistical offices where QMS is applied, and then the apparatus of the State Statistics Committee according to the results of recertification audit conducted on March 02-06, 2020 and another 17 local statistical offices where QMS is applied, then according to the results of recertification audit conducted on February 13-17, 2023, the apparatus of the State Statistics Committee and 45 local statistical offices where QMS "Production and dissemination of official statistical data" is applied, have received the international certificate of conformity 9001:2015 in the direction of "Production and dissemination of official statistics". http://stat.gov.az/menu/2/quality/en/sertifikat_ISO_9001_2015.pdf

On the basis of the “Audit Program” approved annually, internal audits are carried out in the departments of the Office and in the local statistical bodies where the GIS is applied. Audit teams are formed to conduct audits and an individual audit plan is approved for each structural unit. The audit team conducts inspections in accordance with the audit plan. Internal monitoring of quality aspects in the State Statistics Committee is carried out in a centralized manner by the authorized structural unit (Quality Management and Metadata Department) and an annual “Analysis by Management” document is prepared and submitted to the management based on the results of audits. The members of the audit team (auditors) are instructed before each audit by the auditor general, as well as through seminars organized at least once a year. The activity of the State Statistics Committee is “Quality management systems. Requirements ”ISO 9001: 2015 is one of the strongest strengths. Increased workload due to incomplete transition to electronic documentation and parallel paperwork, late adaptation of staff (employees) to the requirements of the new standards are the weakest weaknesses.

Non-sampling error is carried out in accordance with the "Rules for classification and elimination of errors in the reporting data" approved by the decision of the State Statistics Committee No. 9/3 dated October 30, 2019. https://www.stat.gov.az/menu/2/quality/az/00_5.pdf
