During the midst of the 2013 drought, the city of Wichita Falls (TX) was preparing to switch their potable water supply to effluent-sources since the City's water-supply reservoir had dwindled to 15% of normal pool. You know it's bad with you're faced with that option. Fortunately, they finally received a week of rain that completely filled the reservoir.


We call it grey water. Lots of great nutrients in it. I would look at maintaining water quality with hydrated lime. It will tie up soluble nutrients and make them available for the lawn you shoot it on.

Just maintain PH of pond water to 7.2 with hydrated lime and it will grow grass like you have never seen.

Cheers Don.
