Water Supply

This structure is part of the set of improvement measures of the local public supply system

This Thursday, 11/11, the Renova Foundation officially delivered to the City of Linhares an alternative structure for water withdrawal to supply the city. The new pipeline, installed in Lagoa Nova, can meet around 50% of the city consumption, contributing to reduce supply dependency from the Pequeno River.

The pipeline is 9-km long and has a flow capacity of 200 liters per second. Water withdrawn from Lagoa Nova will be taken to the Water Treatment Plant (ETA) from Linhares’ Autonomous Water Sanitation Service (SAAE), where it will be distributed to the city that will define the best way to use the second water withdrawal. The water withdrawal from the Pequeno River will continue as normal and will supply the population with the same water quality as before the turbidity plume passed by, as confirmed by the reports hired by the Renova Foundation and independent entities.

The pipeline installed in Lagoa Nova is the result of a 7-million BRL investment by the Renova Foundation. The structure has been in operation since late September when the monitored operation started, period when the City of Linhares counted with the technical support of the Renova Foundation. All deadlines were in accordance with the agreement signed by Renova, the City, and the State Public Prosecutor.

Still as part of the improvement measures of Linhares’ public supply system, the Renova Foundation is installing, in Regência, a Mobile ETA, one more alternative for water treatment. It will be operating until the ETA renovation work going on now, also by Renova, is completed. The Mobile ETA construction work will be completed in late November and the ongoing renovation work is planned to end in July 2017.

The Mobile ETA uses two actuation systems: ultrafiltration and reverse osmosis. Ultrafiltration is enough to treat almost everything, except for salinity. In case salt is found in the water, the reverse osmosis process is triggered. This system will only be used if ultrafiltration cannot solve the entire problem.

This set of initiatives is part the action plans for the rainy season by the Renova Foundation. The plan consists of preventive and contingency measures implemented to minimize the impacts on society, the environment and the economic activities of the locations impacted by the collapse of the Fundão dam.

Colatina also has a new pipeline

This week, the Renova Foundation also delivered a new alternative structure to supply water in Colatina. The pipeline installed at Santa Maria River will be triggered in case rains bring variation in turbidity to the Doce River, the main water source of the city.

With capacity of 75 liters per second and volume equivalent to 50% of the consumption in the Southern part of Colatina, the Santa Maria River pipeline is ready to work.

The implementation of a pipeline at Pancas River is also ongoing in the municipality, which will supply the Northern part of the city, planned to be ready in January 2017.

The Renova Foundation

The Renova Foundation is an autonomous and independent institute founded to repair the damage caused by the collapse of the Fundão dam, property of Samarco Mineração S.A., located in Mariana (MG). A private non-profit organization, Renova was created to guarantee transparency, legitimacy and sense of urgency to a complex and long term process. The Foundation was established by means of the Transaction and Conduct Adjustment Term (TTAC), signed between Samarco, its shareholders, the federal government and the state governments of Minas Gerais and Espírito Santo, as well as several authorities, foundations and institutes (like Ibama, the Chico Mendes Institute, the National Water Agency, the State Forestry Institute, Funai, Governmental Departments of Environment, among others), in March 2016. The Colatina and Linhares pipelines are included in this document and represent the first delivery by the Renova Foundation in Espírito Santo.
