After nearly a year of research, Delmarva Pool & Pond Co. won us over with their initial consultation. Honest timeline, realistic budget, no pressure. The concrete pool they built is exactly what we designed together. The kids are in it every afternoon. If you want it done right the first time, these are your people.

We went with a fiberglass pool because we wanted something low-maintenance and fast. Delmarva delivered on both site visit to first swim took under two weeks. The crew showed up on time, kept the yard clean, and walked us through the setup before leaving. Three months in, zero issues.

Our pool was original to the house, cracked coping, worn plaster, outdated equipment. Delmarva gave us a clear written scope and stuck to it. They replaced the coping and tile, refinished the shell, and updated the pump system. The craftsmanship is clean and solid. Couldn't be happier.
Ponds & Waterfalls
Natural Water Features Built to Last
A well-built pond or waterfall adds sound, movement, and life to any yard. Delmarva Pool & Pond Co. designs and builds natural aquatic ecosystems across the Delmarva Peninsula—from koi ponds and water gardens to cascading rock waterfalls. We handle excavation, liner installation, filtration, and plant integration to create a self-sustaining water feature.
Custom Ecosystem Design: We balance fish, plants, and filtration for a low-maintenance, thriving water feature. A well-designed pond ecosystem largely takes care of itself—the fish, plants, and beneficial bacteria work together to keep the water healthy.
Natural Stone Waterfalls: Hand-placed rock work creates natural cascades that integrate with your existing landscape. We source stone regionally when possible and place each piece by hand to achieve a look that improves with age.
Koi-Ready Construction: Proper depth, aeration, and filtration are built in from the start for healthy fish. Koi ponds require specific minimum depths to survive Delaware winters and sufficient filtration to handle the biological load fish produce.
Services
Excavation & Liner Installation
Every pond starts with a properly excavated basin and quality liner installation. We design depth zones for fish health, plant shelves for aquatic vegetation, and overflow channels for heavy rainfall. The design phase determines how well the pond functions for years—improvising these elements after the fact is difficult and costly.
Filtration & Rock Work
Biological filtration keeps water clear without chemicals. We source and place natural stone to build waterfalls and edges that look and age like they've always been there. Waterfalls also oxygenate the water, which benefits fish health and reduces algae pressure.
Pond Design & Build
Koi Pond Construction
Depth zones and filtration designed specifically for healthy koi habitats. Proper depth is critical for fish to overwinter safely in Delaware and Maryland climates.
Natural Waterfall Builds
Hand-placed stone cascades built to look natural and last for years. Each stone is positioned for stability and visual flow, not just stacked for appearance.
Aquatic Plant Integration
Marginal and submerged plants help maintain water clarity naturally. They compete with algae for nutrients and provide shade that keeps water temperatures stable.

Do koi ponds require a lot of ongoing maintenance?
A well-designed koi pond with properly sized filtration is very manageable for most homeowners. Routine tasks include feeding, water quality testing, and periodic filter cleaning. We design systems with practical, low-maintenance operation in mind from the start.
What's involved in building a koi pond?
A koi pond build includes excavation, liner or concrete installation, filtration system setup, plumbing, and rockwork. Proper filtration and circulation are critical. Koi produce significant biological load, and the system needs to handle it reliably year-round.
Can you add a waterfall to an existing pond?
In most cases, yes. Adding a waterfall typically involves installing a spillway, connecting it to the existing pump and filtration system, and integrating natural stone or custom rockwork. An on-site visit helps us assess what's feasible with your current setup.
