How much maintenance cost?

The electricity to run a pump for a typical 176-square-foot pond costs about $260 a year. Smaller backyard ponds are much less usually.  Pond filters need frequent cleaning and recommended to be cleaned monthly. If you cannot keep up on the maintenance, hire a pond-maintenance company. Yearly maintenance of ponds costs an average of $2,000 for four regular servicing visits during each of the seasons. People pay $450 on the low end and over $5,000 on the high, but the price is heavily subjective and based on the size and complexity of the pond’s environment.

Where to Put Backyard Ponds?

Backyard Ponds or Lagoon?

The location of a backyard pond determines its health and your ability to enjoy it.

How much sun?

Ideally, ponds should receive sunlight in the morning and shade in the afternoon. This keeps the water cooler, discouraging green algae blooms.

How far from the house should a pond be?

Ponds that are out of sight tend to get quickly neglected. Additionally, if they are farther than 20 feet from your patio or outdoor living space, you likely will not hear the peaceful cascade of a waterfall or fountain.

Does the yard have Overhanging trees?

A tree’s afternoon shade is welcome, but a pond that is directly under a tree’s branches will quickly clog with unwanted leaves, seeds, or pine needles unless given constant maintenance. If your landscape as a nearby tree that is young, factor in its mature size and spread before settling on the location of your backyard ponds.

What do the building codes say?

Ask your local building department about how far a pond must be set back from the home property line.

Where are my utility lines?

In Virginia Dial 811 before any digging to have your utility lines marked. This is a free service by the utility company, and it is Virginia law to be done to avoid damaging underground utilities.  Striking a single utility line can cause personal injury, costly repairs, fines and inconvenient outages.

Pond Materials:

Liner – Utilize these calculations to determine how much material you will need for the pond.  (all measurements in feet)

In simple terms, your pond liner size is always “double your depth added to your dimensions plus a safety overlap”.

Manufactured elastic – The most ideal decision for most ponds, 45-mil-thick EPDM comes in sheets up to 50 by 200 feet. Solid, UV safe, and adaptable to – 40 degrees F. Costs approx. 67 cents per sq. ft.

Plastic – Liners made of polyethylene (PE) and strengthened polypropylene (RPP) are more slender, lighter, and more affordable than EPDM yet stiffer and harder to work with. Costs for 20-mil PE liners, are about 30 cents for each sq. ft., and 36-mil RPP, approx. 45 cents per every sq. ft.

Pond Pumps:

Select the right size pump for your backyard ponds.  At minimum, the gallons every hour (GPH) rating should match the volume of your pond. The pump will require extra GPH to properly supply a cascade waterfall or fountain, and enough “head” to push water to the top of the waterfall or fountain. Search for the right pump for the pond with the lowest wattage, which will cost the least to run.

Pond Filters:

Pond Filters

Pond filters help keep water free of debris so that the pump will not clog. Other filter types remove chemicals that can harm fish. To sustain fish in your backyard ponds, you will need both types or a product that has both filters in one package.


Mechanical filters trap debris before it reaches the pump. It’s best to clean filters weekly in spring and fall, every other week in summer, and monthly in winter. A filter in a waterfall or a surface skimmer is easier to reach than one on a pump placed at the bottom of pond.  Costs vary on filters and range from $60—$800. 


Biological filters are a must for ponds with fish. Bacteria living on a porous filter medium will digest toxic nitrites and ammonia that is harmful to fish. You should wait at least 72 hours or more before putting fish in your new pond. By taking these actions, the water temperature and chemistry can level out. Note: Drastic changes in your backyard ponds can have a serious impact on the health of your fish.  Filter costs vary and can range from $140 — $500 depending on what your pond needs.

Pond Equipment:

Water Agitators

Your pond will become a stagnant and an algae-filled eyesore if you don’t keep the water moving and properly aerated. Here are three ways to agitate the pond:

Water Fountain

Water shooting up from the surface of the pond or flowing from a man-made ornament is visually compelling and nice to listen to in your outdoor spaces. Fountains come in a variety of sizes and shapes and require the right pump to function at full capacity.

To create the tranquil waterfall you want, measure its width in inches at the point water spills out. Multiply by 50 if you want a trickle of water, by 100 for a sheet of water, and by 200 for Niagara Falls type action. The result is how many GPH your pump will need for the falls alone and does not factor in the pond requirements.

Bubbler air pumps are separate devices from a pond pump and produces bubbles that subtly ripple the pond’s surface.

DIY Pond Kits

Koolatron Pond Kit – 84 Gallon

Most online retailers bundle the backyard ponds essentials. Or you can buy a prepackaged kit from a home center that includes a rigid plastic tub, flexible tubing, and a properly sized pump. These kits are small and manageable enough to install in a weekend, but they don’t include the biological filter you need for fish. Though you could add such a filter, they’re really intended to be low-maintenance water features for people who want the pleasant sound of trickling water near a deck or patio, not a full-fledged ecosystem.
