Straight straight pond
A sleek rectangular pond is also a great solution for collecting rainwater. Rainwater is not always of the same quality and therefore not suitable for all fish. However, fish in the pond are important for keeping the plants clean and controlling mosquitoes. You can, however, take some measures to keep the water quality good.
In the pond liner you can make water passages for the supply of rainwater. The drain is needed for excess water and any cables and pipes. Of course, you can also choose from several of ornamental elements and running water.
Cost
With a simple pond, the cost is usually limited. If you choose flowing water and many decorative elements, then this pond is a bit more expensive.
Space use
A pond requires a relatively large amount of space.
Difficulty
There are different types of sleek ponds. You can buy wooden kits with accompanying pond liner. If you are a bit handy, such a pond is easy to build yourself. To avoid pond leaks, however, care is important. If you choose a masonry or stone pond, you need a professional.
Earthmoving
A pond requires a lot of ground work. It is best to build a pond at the lowest point. The soil you no longer need can be disposed of.
Maintenance
A pond needs regular maintenance. In the rainwater pond you put out fish suitable for a nutrient-rich and more acidic environment. In addition to the fish, the aquatic plants also need maintenance and the removal of debris from the pond.
Climate Goals
The pond reduces heat stress and captures almost all rainwater. This relieves the sewer system and replenishes groundwater in the garden. A tight pond has no riparian zone so its contribution to biodiversity is less than a natural pond.

Points of interest
- Place the pond in a lower part of your yard, then when the bank and pond are full you will still have plenty of buffer space.
- There should be sufficient space to collect excess pond water.
- Put out strong fish in the pond; fish that can withstand rainwater, clean the plants and eat mosquito larvae.
- In old homes, the downspout is often also the vent to the dirty water sewer. If you disconnect this downspout then you must restore the venting.
