Brazil's water agency ANA says that São Paulo state water utility Sabesp is extracting deeply settled water from the Cantareira water supply system without regulatory approval and violating a federal court order against the practice, state news service Agência Brasil reported.

According to an ANA inspection of the Atibainha reservoir, which is part of Cantareira, the level of so-called dead volume water is 38cm below the authorized limit.

ANA has requested that state water and electricity department DAEE look into the matter, the report said.

Sabesp, which extracted deeply settled water in May to increase water supply in Cantareira, was said to be considering a second round of extraction of dead volume water.

But the federal government has set water extraction restrictions. For now, water cannot be extracted below 815m in the Jaguari and Jacareí basins and below 777m in the Atibainha basin.
