Brazil's Alagoas state water utility Casal will call a 132mn-real (US$80mn) tender by month-end for a 30-year public-private partnership (PPP) to update the water supply system in Arapiraca city and surrounding areas, Casal VP Alvaro Jose Menezes told BNamericas.
The project is aimed at meeting the increasing potable water demand in Arapiraca in the short term and providing water for 10 nearby towns in the long term.
The awardee will lay some 95km of pipeline, install two pumping stations and build a potable water plant with capacity to treat 1,200m3/h, or 1,260m3/h counting its water reuse component.
A total of 1500m3/h of water will come from the city of Traipu, with 1,000m3/h being directed to a new water treatment plant in Arapiraca and 500m3/h being channeled to serve mining company Mineraçao Vale Verde in Craibas.
By the end of the concession period, the water supply system should have capacity to supply 200l/d to Arapiraca and 167l/d to the surrounding area. The Arapiraca distribution network will also be updated to handle 2,250m3/h.
The PPP contract also calls for a reduction in the area's water loss rate from 40% to 25% by the year 2020, the executive said.
