I run eight low-pressure (gravity fed) drip irrigation systems at our farm and house.

My experience is that they work very well for "spot" irrigation, such as getting a few trees, shrubs, or tomato plants established and watered during drought periods.

I cannot envision any easy way to irrigate an "area" with that type of system.

I agree with Augie, a sprinkler pump would be by far the best solution to watering an area of any significant size.

Especially, if you have electricity at or near your pond.
