Mexico's state-owned oil and gas company, Pemex, has entered into an agreement to develop water and wastewater infrastructure for its upstream and downstream facilities in Mexico.

The partnership with Global Water Development Partners (GWDP), founded by private equity funds managed by Blackstone, aims to boost Pemex's efforts to design, finance and implement critical and environmentally conscious solutions for its oil and gas water and wastewater treatment operations.

Jose Manuel Carrera, general director of Pemex's international arm, PMI, said the partnership will enable Pemex to better focus its financial resources on its core business, while also addressing its water and wastewater needs.

"In addition to providing a source of financing, the partnership will facilitate access to the industry's most advanced technology and integrated full-service water systems for all of Pemex's water supply and wastewater treatment needs at both its onshore and offshore oil production facilities, refineries and petrochemical plants," he added.

GWDP was established by Blackstone last year as a platform for expanding its investment in the global water and waste sector.

Welcoming the new agreement, GWDP's CEO, Usha Rao-Monari, said: "We look forward to partnering with Pemex to provide innovative and sustainable water solutions throughout its value chain."

In a separate project, Spain's Abengoa and Italy's Enel Green Power will construct a cogeneration plant that will supply power to Pemex's Antonio DovalÌ Jaime refinery in southern Mexico.
