A Complete Guide to drain system design and installation

A drain system will only be efficient if sufficient effort is put into the initial stage. Different types of drainages work differently. All drainages, however, serve similar general purposes. Whether they are installed on a bridge or in a building, the purpose of a drainage system is to remove excess water from the surface and allow it to flow somewhere it will not cause damage.

Often drainages will direct to creeks, rivers, beaches, or other water outlets to avoid damage to commercial homes, land, and property. However, that is not always the case. Sometimes, they simply slow down the absorption rate of water so that the land has time to adjust without causing any damage.

Drainage and grading are an apparent concern in rainy climates. Even in areas with little and moderate rainfall, proper grading can prevent problems such as draining towards the foundation and water puddling in the landscape. Don’t let a drain problem go unattended in your garden. Poor drain issues may cause water damage problems that are costly to fix. A proper drain system design and installation is the only solution to ensure that the excess water on your yard drains properly. 

Importance of drain system design and installation

When constructing roads, bridges, buildings or, other structures, it might look like water systems should be an afterthought. However, drainage system design is a crucial part of building before ever breaking ground. Because water can cause much damage if you don’t have any plan for it. In the case of significant rain or flooding, water will pool. If water does not have any place to go, you are looking at potential foundation problems, sinkholes, erosion, and more.

Surely, those are the worst-case scenarios. However, a little water damage can also cause mold, cracking, discoloration, and more that no one wants. That is why it is critical to address a building’s drain system from the beginning.

Pros and Cons of drain system design and installation

In addition to installing a drain system under your basement, a well-planned landscape also requires a good drain system. Install a drain system before creating your garden beds or laying down sods. Although considered by farmers and gardeners as beneficial, a drain system has some disadvantages too. Learning the pros and cons of drain systems will help you determine whether installing one will work great for your garden and its environment.

Pros of drain system

Prevents water accumulation

Drain systems can prevent water accumulation that can lead to flooding by directing the water away from your house. Over-accumulating water in your yard may kill plants. The drain system also prevents the accumulation of stagnant water, which can encourage mosquitos to breed.

Reduces soil erosion

Over time, accumulated stagnant water can make soil muddy, which in turn can erode the soil. Drain systems maintain balanced moisture in your garden to reduce erosion of soil.

Removes disease organisms and toxic materials

Continuous heavy rains may cause the water level to rise that can lead to flash floods. These flash floods often bring contaminated water into soil. Drain systems will be able to remove these toxic materials by draining them away from your garden.

Cons of drain system


Installing a drain system is a costly investment. You will end up paying a high price, especially if you hire a professional for drain system design and installation. You may even need permission to install a drain system, especially if your specific project requires various channels and deep excavations.


Regular maintenance of your drain system will make sure that it functions properly at all times. You have to make sure that the outlet ditches of your subsurface systems don’t have any blockages caused by sediment buildup. You will need to look that debris does not seal the inlet covers. If your drain system tile breaks, you have to replace it. Removing water-loving trees such as elm, willow, cottonwood, and soft maple from within 100 drain feet will keep your drainage away from blockages caused by overgrown roots, fallen branches, and leaves from these trees. Ochre, an iron oxide that can block your drainage pipe, may also build up. Therefore, you continuously have to be on the lookout for it.   

Can contaminate water bodies

Drain systems can also contribute to contamination issues, especially when not maintained properly. According to the study, subsurface drain systems can carry nitrate through the drainage pipes, channeling it into the bodies of water such as rivers, lakes, and streams.


At the end of the day, a homeowner with a garden or yard must ensure a proper water drain system design and installation to refrain from the possibility of water damage caused by standing water. If standing water goes into your home and does not drain away, the water can cause serious damage to the roof, ceiling, walls, and floors.
