Peru, where millions live without potable water and sewerage services, is accelerating plans to award billions of dollars in PPPs in the sector.
The public works minister said he expects a new US$9bn infrastructure fund to be approved by congress in the next few weeks.
The glacier law has been in the books since 2010.
The bid opening ceremony for the tender to build a potable water treatment plant in La Arenosa had been scheduled for November 14.
The US$130mn reservoir is expected to be completed by 2020 and will have capacity for up to 17Mm3 of water.
The two contracts have a combined price tag of US$7mn and are aimed at combating a severe drought that has affected the Pilcomayo river.
Over half of the 402bn pesos (US$134mn) allocated to the aqueduct will come from state oil company Ecopetrol.
