DAEE plans Taquaritinga wastewater treatment plant tender

Monday, November 14, 2011

Southeastern Brazil's São Paulo state water and electricity department DAEE is planning a 14.5mn-real (US$8.25mn) tender to build a wastewater treatment plant for the city of Taquaritinga, a DAEE spokesperson told BNamericas.

Governor Geraldo Alckmin was due to sign an agreement on Monday (Nov 14) in Taquaritinga, accompanied by national sanitation and water resources secretary Edson Giriboni and DAEE superintendant Alceu Segamarchi Jr.

"Since the project's basic plan is done and environmental licensing has been obtained, the signing of the agreement gives us the green light to call for bids," the spokesperson said, without specifying a schedule for the tender.

The plant will have two UASB reactors, two biological filters, two secondary settling tanks, a chlorinating system, wastewater outfalls, and a pumping station.

The facility will serve 100% of Taquaritinga's population until 2031, when its population is expected to hit some 67,000, the official said.

Currently, 90t of waste from the city is released each month into the Porcos river, a tributary of the São Lourenço river that eventually flows into the Tietê river.

The work falls under the state's Água Limpa (clean water) program, created in 2005 to improve sanitation services in municipalities with up to 50,000 residents that are not covered by state water utility Sabesp (Bovespa: SBSP3, NYSE: SBS).
