The Ministry of Housing, Construction and Sanitation began the second phase of topographic work and collection of social information for Stage II of the Comprehensive Drinking Water and Sewerage Project (PIAA) in Juliaca, according to an April 21 announcement. The project aims to improve water and sanitation services for more than 370,000 residents in the Puno region.
This development is significant as it addresses gaps in access to clean water and sanitation, which are crucial for public health and sustainable urban growth. The ministry said that activities have started in Taparachi (Cusco exit) and Horacio Zevallos (Puno exit), with inspections planned for 31 neighborhoods out of a total of 87 that will benefit from this stage.
“We promised to push forward the PIAA, and we are delivering. It is an important project for the region and Peru that will allow us to significantly reduce the gap in drinking water and sanitation,” Minister Wilder Sifuentes Quilcate said.
The first phase verified conditions at over 17,500 homes, with initial sanitation works carried out in Santa Ana (Arequipa exit), Cincuentenario Cancollani, San Pablo, and San Paulino (Lampa exit). Current interventions include excavation, pipe installation for potable water, trench filling, hydraulic testing, and placement of sewer system manholes across several neighborhoods.
Stage II involves installing more than 25,000 household water connections along with new primary lines spanning nearly five kilometers. It also includes constructing a new reservoir while upgrading existing systems. For sewerage infrastructure, over six thousand connections will be added or renewed along with dozens of kilometers of main collectors.
The Ministry operates as an autonomous entity within Peru’s Executive Branch established by Law No. 27779 according to its official website. It develops policies promoting sustainable access to housing, construction services such as water management projects like PIAA Juliaca as reported by the ministry. The ministry contributes to social wellbeing by enhancing access to basic services across communities nationwide through its headquarters in Lima’s San Isidro district as well as regional centers according to official sources.
Officials say that upon completion this megaproject will positively impact families across more than two hundred neighborhoods in Juliaca and San Miguel districts by providing improved living conditions.
