I have visited these garden three times. The garden has creeks and large man-made lakes and ponds. The 6½ acre (2.6 ha) park uses the reclaimed water from the adjoining Donald C. Tillman Water Reclamation Plant.
The water from the reclamation facility can only be used for irrigation and is not cycled into the general water supply. The facility purifies waste water, removing it from the sewer system. This reclaimed water from the West San Fernando Valley is also used to fill Lake Balboa in the adjoining park as well as providing year round water to the LA River.
The reclamation facility has also been used as a backdrop in films and TV, including Star Trek‘s Starfleet Academy and Soilent Green.
