Brazil's São Paulo state water and electricity department DAEE has launched a tender for a project to restore electrical and mechanical installations associated with pumping stations in the state's Paraíba valley area, a DAEE spokesperson told BNamericas.
The work is specifically aimed at improving the management of polders or low areas of land enclosed by dikes.
"The bidding competition, which contemplates work for polders Lorena I and Pinda IV, will take place on July 13," the spokesperson said.
No ceiling price has been set for the tender, which will be carried out through an onsite bidding process, which is aimed at speeding up the work.
The artificially managed wetlands are important for agricultural activities in the region which are regularly hit by floods and periods of severe drought. A system of canals and pumps is used to improve the region's production of rice, corn, potatoes, cassava, beans, and vegetables.
DAEE maintains 16 polder areas in the Paraíba valley, located in the municipalities of Taubaté, Tremembé, Pindamonhangaba, Roseira, Aparecida, Guaratinguetá, Lorena, Cachoeira Paulista and Canas.
