Pays/région Période Budget
01.01.2010 - 31.12.2022
CHF  19’000’000

EPS Grau is one of the largest water utilities in Peru and provides water and sanitation services to around 750’000 residents in the entire region (77% water supply, 62% sanitation coverage). EPS Grau and their customers are highly dependent on the efficient use and protection of the scarce and vulnerable water resources. The further development of the economically important coastal region (fishery, gas and oil production) is hampered by the inadequate and unreliable water supply as well as by pollution due to insufficient wastewater treatment.


The overall objective of the integrated project is to ensure the sustainable growth of the economically important coastal area of Piura through a reliable and affordable water supply system, to enable EPS Grau attaining financial sustainability in their operations and to promote a sound management of the regional water resources.
