Major constraints of this project include the following:

c. The basin intermediate slab surfaces and walkways have limited weight restrictions.
d. Access into the lower level portions (including flocculators and residuals collectors) of Basins 3 and 4 is limited.
e. The worksite is a secure facility with specific access and personnel requirements.
