The average pond maintenance cost is $2,000. But how much you pay to take care of your pond depends on multiple factors, such as the size of the pond and whether fish live in it. Your area's climate also affects the overall maintenance cost, as you may need to winterize your pond to protect it and any aquatic life in it during the colder months.

You have several options for your pond by getting your yard ready for the winter. You can winterize your koi pond by ensuring it’s at least 5 feet deep so it doesn’t freeze completely, installing a pond heater or aerator and having it run at all times, and installing a deicer if temperatures are dangerously low for an extended period. You can also choose to shut down your pond for the winter by removing all the wildlife in it and bringing it indoors, cleaning out the filter and pump, and then covering the pond with a tarp.

In addition to length and width, pond liners also come in various thickness levels. Thickness is measured in mils, a unit of measurement equal to one-thousandth of an inch, with most pond liners ranging from 15 to 60 mils in thickness. The smaller the number, the thinner (and weaker) the liner. To prevent rips and tears, it’s best to choose a pond liner that’s at least 30 mils thick.

Lifespans vary by material and manufacturer, but pond liners last anywhere from 10 to 75 years. For example, polyvinyl chloride (PVC) pond liners have a life expectancy of up to 20 years. Other types of pond liners, including those made of high-density polyethylene (HDPE) and ethylene propylene diene monomer (EPDM), can last 40 to 50 years.
