1st Course in Mutirão the site Pátriaterra

Curso Patriaterra

The Office of Sustainability launched in Pátritaterra a series of courses in Sustainable task force. In the course participants learned to build the basin, putting their hands dirty, and calculate the dimensions suitable for every situation and every operating system including how to make your maintenance.

It took one day to complete all layers and on the day following planting on its surface with a suitable distribution. Meals and welfare of participants was ensured by Isabela Menezes who led his team and provided more encouragement to continue the work and good energy.
While the course was going, partners Forest Carbon took the energy to start planting native plants along one of the streams of the site.

The seedlings were carefully selected and distributed according to their ecological functions among species we planted, Uvaia, Guapuruvu, Paineira Rose, Cedar Rose, Inga Bean and Palmito Juçara.

On the second day, the staff of BET Course after completion of the basin, helped plant the seedlings and tutor them them. The rain hampered a little work, but the willpower team ensured that the work was completed.

Participants also had the opportunity to learn about the work of the Institute for Social and Environmental Research Projects (IPESA) in the region represented by Luciana presented videos and booklets developed for the project Water Management and Clean-River Integrated Community which aims to disseminate alternative appropriate management of water in the Rural Area through an environmental education program.

Just two days after fulfilling the Pátriaterra which is already beautiful by its nature is more beautiful and full of good energy from people interested and ready for action.
Located in the tourist city of Ibiúna which is part of the Watershed Committee of Sorocaba Rivers and Middle Tietê, Pátriaterra the site is within the Conservation Areas of Biodiversity and Conservation of Water Resources in APA (Environmental Protection Area) Itupararanga.

Near the site and within the region of the APA are two dams supplying the region: Itupararanga Waterfall and France.

Therefore, one of the main interests and objectives of the region is the protection of its watershed and its biodiversity. And to ensure the achievement of this goal there are several programs both public initiative and private sector working in the direct protection and promotion of sustainable practices in the use and occupation of land and water.

The Pátriaterra want to be a space disseminating knowledge and sustainable practices for the region and beyond. And the first step was taken this weekend, with the first course of a joint effort to build a basin evapotranspiration, taught by Mark permacultor Nobody.

The technology Basin Evapotranspiration was created to solve a problem is still relevant in our society, organic waste or sewage. In many Brazilian cities, especially in the countryside, it is still common in the release of effluents cesspools, or directly into rivers and streams.

A cesspit is not a closed system, although it seems as it is not sealed and water with the waste (black water) penetrates the soil to reach groundwater and water bodies consecutively.

Unlike the cesspit, the Basin Evapotranspiration (ET) or “pit banana” is a closed system that treats black water so as not to generate any effluent and contamination of water bodies.

The water went through the process of evaporation back to enter the natural cycle of water and wastes are decomposed by anaerobic bacteria in a fermentation process.

This breakdown occurs within a tire chamber, insulated by a layer of rubble. The other layers that cover this camera are rubble and gravel, fine sand, coarse sand substrate.

The water entering the system will only come out in the form of steam, because with increasing temperature in the fermentation process this water evaporates and rises through the following layers like passing through a filter.

The last layer possess plants absorb water through the roots and returned to the atmosphere through transpiration, thus the name given to the system is evapotranspiration.
