let the Tillman reclaimed water run through the river, before diverting it for other beneficial uses.
Distribute advanced water reclamation (like the La Noria waterwheel) downstream of where the water can provide multiple uses and still be practicably reclaimed. Of course this is a much more complicated scheme than just piping the water directly to Pacoima from the Tillman Plant for "Advanced Water Treatment", but the potential benefit of having a watered river far exceeds the cost. The River we now know is far from irrepressible. It has been re-materialized by reclaimed water, a resource now in the city's crosshairs.
The River is now effectively a fountain that we will someday turn off unless it becomes integrated with our water resource management practices.
