When it comes to creating a serene backyard oasis, pondless waterfalls are a popular feature. However, homeowners face a crucial decision between using concrete or pond liners for construction. The pond liner industry has seen prices soar, often equating to the cost of concrete builds. Yet, the durability and longevity of concrete waterfalls may make them a more sensible investment. This article delves into the comparison, providing insights and statistics to guide your choice.
Concrete waterfalls, often referred to as the "apples" in this comparison, boast a robust construction that can last a lifetime. The process involves excavation, installation of a flexible PVC pipe, and the use of 3500 psi concrete reinforced with stealth fiber and rebar. A high-efficiency pump and anti-vortex drain are also integral components. The total cost for a concrete pondless waterfall, based on a specific size and design, can amount to approximately $2,236.
Concrete offers several advantages:
On the other hand, pond liners, or "lemons," are often marketed by companies with a vested interest in promoting their product. A typical pondless waterfall liner kit can cost around $2,176, which does not include installation. While the initial cost may be slightly lower than concrete, pond liners come with their own set of challenges:
When comparing the operational costs, concrete waterfalls with above-ground pumps are more energy-efficient, producing 5,800 gallons per hour at 356 watts. In contrast, the liner kit's sump pump generates slightly less water flow at a significantly higher energy consumption of 911 watts. This difference can result in an additional $525 in annual electricity costs, based on an average rate of $0.12/kWh.
Concrete waterfalls allow for design modifications during construction, offering the flexibility to alter dimensions and shapes. Liner waterfalls, however, are restricted by the pre-set parameters of the kit. Moreover, the stability of mortared rocks in concrete waterfalls enhances safety, especially for children, compared to the shifting rocks of liner waterfalls.
When weighing the options between concrete and pond liners for pondless waterfalls, it's essential to consider the long-term durability, maintenance, energy efficiency, and safety. Concrete waterfalls may present a slightly higher upfront cost but offer substantial benefits and a lifetime warranty. In contrast, pond liners may have hidden long-term costs and limitations.
It's worth noting that while some professionals install liners with additional precautions against damage, the extra effort and expense could be better invested in a concrete construction from the start.
In conclusion, concrete waterfalls stand out as a permanent, cost-effective, and aesthetically pleasing option for those seeking a reliable pondless waterfall feature. As you make your decision, consider the long-term implications and choose the option that aligns with your vision for a tranquil backyard retreat.

Water serves three major purposes in our bodies. 1. It controls body temperature. 2. It is the solvent for the foods we eat, carrying the nutrients to every cell of our body. 3. Water replaces bodily fluids such as blood plasma, lymph, digestive juices, bile etc. and washes and bathes every cell, flushing and carrying away waste materials and toxic poisons. If water is so vital to our health and existence, shouldn't we drink the healthiest water possible?

The Durability of Concrete Ponds in Frigid Environments
Concrete ponds have often been criticized by proponents of pond liners, who claim that concrete is prone to cracking and cannot withstand the harsh conditions of cold climates. However, this article aims to dispel these myths by presenting the facts about the resilience of concrete ponds, especially when compared to rubber liners, and the engineering principles that ensure their longevity.
