Turkmenistan's Ministry of Construction and Architecture has formally approved new building codes titled "Water Supply. External Networks and Facilities" (TGK 2.04.02-2026) via a decree issued on June 26, 2026. The technical standard, which replaces previous infrastructure design protocols, was officially registered by the Ministry of Justice of Turkmenistan on July 29, 2026.

Under the updated regulatory framework, daily per capita potable water consumption standards are categorized according to residential infrastructure levels:

Dwellings without baths: 160–200 liters per person daily.

Homes with baths and localized water heaters: 210–260 liters per person daily.

Residences with centralized hot water systems: 300–450 liters per person daily.

Public standpipe usage: 30–50 liters per person daily (subject to reduction during water supply constraints).

For master planning and regional zoning, aggregate daily consumption benchmarks have been established. Urban targets are set at 550 liters per resident daily for initial development phases and 600 liters for long-term planning periods. Rural allocations are fixed at 125 and 150 liters daily per capita, reflecting differences in utility infrastructure density.

Additionally, the code standardizes fire-suppression water flow rates, sanitary protection zones around water sources, purification protocols, and engineering guidelines for constructing water transport facilities in seismic zones or unstable soil conditions.
