Water Allocation in the MAURE – MAURI transboundary basin

INTRODUCTION

• Peru has 34 transboundaries basins along its borders.

• Peru shares superficial and ground waters with all its neighbors.

• The south region of the country is located at the northern part of the Atacama desert, and is considered the most arid region on the world.

• Tacna is the main city of the region, and for the last 10 years it has been suffering of water scarcity.

WATER USE AND CONSUMPTION IN TACNA REGION

TACNA

The Tacna region has 4 main basins used for population use, food production, energy, among

others uses. This basins of Tacna are: the Locumba river, the Sama river, the Caplina river and the

basin composed by the Maure, Uchusuma and Caño rivers.

The basin of the river Maure is very

important for Tacna. The use of its

waters could ensure the supply of this

resource for the growing population of

341,838 thousand inhabitants and the

improvement of water supply for the

agricultural development.

At present its waters are captured through the Kovire tunnel with an average flow of 0.5 m3 / s and are derived to the

Aricota lagoon for the generation of energy (hydroelectric). In this regard, the Ministry of Foreign Affairs has been

developing binational negotiations on the use of the waters of the Maure River, within the framework of the Binational

Technical Commission - CTB Maure Mauri.

BINATIONAL TECHNICAL COMMITTEE– CTB MAURE MAURI.

Within the framework of CTB Maure Mauri, the Peruvian Ministry of Foreign Affairs forwarded to the Bolivian

authorities the Mathematical Model Study of the Maure Basin prepared by the National Water Authority of Peru

with the objective of defining the present and future scenarios that test the exploitation of dams, canals and

other hydraulic works for the derivation of approximately 2.4 m3 / s additional to current volume used.
