T.R.E.E. Facility Upgrade

TEACHING RESPONSIBLE EARTH EDUCATIONRemedial Water Strategy

A Tulane City Center Project

2Situated along the Little Tchefuncta River outside Covington, Louisiana on Lake Pontchartrain’s North Shore, Teaching Responsible Earth Edu-cation (T.R.E.E.) is an organization that provides curriculum based, en-vironmental education to students in Orleans and adjoining Parishes. Upwards of 50 students in grades 5 and 7 spend 4 to 5 days at T.R.E.E.’s 22.5-acre training ground. Under the instruction of Sue Brown, the ex-ecutive director, and others, the students are exposed to the systems on Earth through thought provoking activities in the natural environment on site. This engagement creates the impulsion for children to make wiser decisions on how to preserve the diversity of our natural world and to make informed choices to live more lightly on our planet.

Built in the early 1900s, the facilities at T.R.E.E. have worn through the years and have not been upgraded to accommodate the growing number of students entering the program. Currently, there are only three function-ing shower stalls for use by the participants during their days-long stay. As well, the septic systems for all the structures (dining hall, bunk house and main residence and office) are in serious need of fundamental repair and enlargement. While the owners make earnest attempts to maintain the system as is, considering the growth of the program, the need for complete redevelopment of septic and bathing facilities is a must.

As such, the scheme proposed by the Tulane team is to add a new 12-shower bathhouse, completely renovate the septic system and spec-ify water saving plumbing fixtures throughout. The two components were developed jointly to enhance the programs mission and reinforce the formal order at the site. In this case, a large cleansing pond will take the place of the existing field lines, providing for the students another teach-ing tool about natural processes, while alleviating the need for costly code-mandated sewage equipment. The bathhouse, a standalone build-ing, is located to formalize the student entry to the facilities. The simple form evokes similar qualities of the existing structures, though tweaked in this case to express raised floor plates required in this flood plane as well as the roofs role in channeling rainwater for use in an entryway didactic water garden.
