The southern portion of this project is the main pond, which at this stage is lined, with the two islands under development.
This 12-by-7-by-7-foot precast concrete vault will be one of several pump vaults. As you can see, there are numerous pipes and conduits running to and from the vault, and all have to be accounted for. An image taken from higher elevations will provide details for the actual location of each vault and valve box within the project.
