Can you recommend an eco-friendly way to maintain a koi pond in my backyard?

Asked by Don Standridge

I have an amazing 2500-gallon koi pond built in the 1920s. It's the main focal point of my landscape. With water restrictions becoming more strict in Central California, can you recommend an alternative landscape feature, or point me to inspiration for the pond that would use less or no water?

It sounds like a lovely feature. Finding another source for water is the answer I recommend.

  • I would suggest installing a rainwater barrel collection system on your home that collects the water from your gutters and feeds it to the pond via gravity.
  • Then install a small, economical solar water pump to create a fountain or to filter/maintain the pond.

You can also consider installing a graywater collection system to gather water from showers, sinks, dishwashers, etc., and filter it for use in the pond.
