Scott Anderson Design has been installing custom koi ponds, ecosystem ponds, pondless waterfalls, and water features throughout Nassau County for over 20 years. As a CAC Certified Aquascape Contractor and licensed landscape designer, Scott brings architectural precision and deep water feature expertise to every installation.
From Bellmore and Merrick to Oyster Bay, Muttontown, Great Neck, and Garden City — we've built ponds in backyards across Nassau County. Every project starts with a free site visit, custom design options, and a transparent price quote.
Custom koi pond installations start at $9,000 for a small ecosystem pond and range to $25,000+ for large ponds. Pondless waterfalls start at $6,000. All installations are turnkey — no hidden materials costs. See the full pricing guide.
Requirements vary by town and pond size. Scott Anderson Design handles all permit research and submissions as part of our full-service process — you don't have to navigate the approval process alone.
We serve all of Nassau County, including Bellmore, Merrick, Massapequa, Seaford, Wantagh, Garden City, Mineola, Great Neck, Manhasset, Oyster Bay, Muttontown, Brookville, Old Westbury, Roslyn, Port Washington, Syosset, Jericho, Plainview, Hicksville, and dozens more. See our full Nassau County service area page.
Most installations take 3–5 days for a standard pond. Larger custom projects with streams and extensive stonework may take 7–10 days.
