Water Feature Types & Options
From simple bubblers to full-scale koi ponds, we design and build water features for every style and budget.
Koi Ponds
Complete koi pond systems including design, excavation, EPDM liner installation, biological and mechanical filtration, UV sterilization, and fish-safe landscaping. Built to thrive through Massachusetts winters with proper depth and aeration.
Fountains & Waterfalls
Natural stone fountains and cascading waterfalls that integrate seamlessly into your landscape. Custom-built from granite, fieldstone, or bluestone with concealed plumbing and recirculating pump systems.
Lily Ponds
Serene garden ponds with aquatic plants, water lilies, and natural stone edging. Lower maintenance than koi ponds while delivering stunning visual impact and attracting beneficial wildlife.
Pondless Waterfalls
The beauty and sound of a waterfall without a standing pond. Water recirculates through a hidden underground basin — perfect for families with small children or limited yard space.

Filtration Systems
Biological filters, mechanical skimmers, UV sterilizers, and high-efficiency pumps sized for your water feature.

Water Feature FAQ
A professionally installed koi pond in Massachusetts typically costs between $8,000 and $30,000 depending on size, depth, filtration system, and surrounding landscaping. Smaller garden ponds start around $5,000, while large show-quality koi ponds with advanced filtration can exceed $25,000.
Yes, koi can absolutely survive Massachusetts winters with proper pond design. The pond must be at least 3 to 4 feet deep to prevent complete freezing. A de-icer or aerator keeps a hole in the ice surface for essential gas exchange. We design every koi pond with New England winters in mind.
Koi ponds require weekly checks on water quality, filtration, and fish health. Seasonal maintenance includes spring cleaning, filter servicing, fall netting to catch leaves, and winterization. We offer monthly maintenance plans starting at $150 per month to handle it all for you.
