Drainage is an important part of the infrastructure from ancient times to the present day and is done in many ways. Drainage pipes are required in every location to take wastewater from our homes and industrial areas. There are different types of drainage pipes available depending on the application. The importance of good drainage can help prevent water build-ups, flooding, structural damage, and soil erosion among other things – so having your drainage systems up to scratch is crucial to avoid bigger problems down the road. In this article, we’ll go over the different types of drainage systems.
What is a Drainage Pipe?
A drainage pipe is a pipe designed to drain water away from a building’s foundation. Drainage pipes allow water to flow naturally to the nearest stream, river, lake, ocean, etc. There are many types of drainage pipes; some are designed to drain water from roofs, while others drain water away from land. Water removal is necessary to prevent flooding of basements, damage to structures, soil erosion, and the creation of swamp-like conditions around a home or property.
There are two types of drainage pipes: storm and sanitary. Storm drains collect rainwater runoff from streets and parking lots. They are designed to drain into the city sewer system. Sanitary drains are designed to drain toilet wastewater and sewage from homes, businesses, and commercial buildings. Sanitary drains are typically made of concrete and lead directly to a sewer line. Storm drains are usually made of metal and lead to a catch basin.
How does the drainage system work?
When rain falls on a roof, it collects on the surface of the roof. Water then runs down the roof into the gutters. Gutters direct the flow of water away from the house. As the water flows through the gutter, it hits something called a downspout. Downspouts are designed to catch the water and funnel it away from the house. This is where the drainage pipe comes in. A drainage pipe is connected to the downspout. This allows the water to drain into the drainage pipe. The water then flows out of the pipe and into a nearby storm sewer system.
Drainage pipes are used for a variety of reasons.
- Flooding: A drainage pipe helps prevent flooding. If there isn’t a drainage pipe, the water would collect on the roof and run off into the ground. Flooding could damage property or cause health issues.
- Surface runoff: A drainage pipe keeps the area around your home dry. Surface runoff can cause erosion and damage the soil and vegetation near your home.
- Prevent Pollution: A drainage pipe helps prevent pollution. Storm sewers are connected to wastewater treatment plants where pollutants such as oil and grease are removed.
Different Types of Drainage Pipes
If you decide to use a drainage pipe, you must first determine what type of pipe you need. Choose a pipe material that is strong enough, yet as simple to install as possible. Once you have chosen a type of pipe, you must then decide where you would like to place the pipe.
Corrugated Polyethylene Drainage Pipes
The corrugated polyethylene drainage pipe is a strong, durable and cost-effective solution for a good drainage system. They are made up of corrugated sheets of plastic bonded together using heat and pressure. It is commonly used in storm sewers and sanitary sewer systems. It is a flexible type of plastic that is easy to install and manipulate. Corrugated pipe is an economical alternative to other materials like concrete and steel. Plastic drainage pipes made from HDPE/N 12 corrugated dual walls are the strongest.
PVC Drainage Pipes
Pipes made of polyvinyl chloride are most commonly used for drainage projects. PVC is considered to be one of the most versatile plastics available. It is durable, flexible, and resistant to chemicals. Flexible PVC pipes are typically used in irrigation systems, storm drains and sewers. These pipes are thinner than their rigid counterparts. This makes them easier to install and repair. However, these pipes tend to break easily. SDR 35 PVC drainage pipes are mainly used for municipal sewer systems, but can be used for other purposes as well.
Concrete Drainage Pipes
When it comes to drainage projects requiring heavy-duty piping, concrete drainage pipes are a popular and inexpensive option. It’s often used when it’s critical that the pipes do not leak or become damaged. Furthermore, concrete can also be used to support another kind of drainage pipe. Unlike other plastic pipes, these pipes are eco-friendly and non-flammable. They are mostly used in commercial applications.
Other Materials: There are many pipe materials that can be used for drainage like Ceramic drainage pipes, Cast Iron Drainage Pipes, Copper Drainage Pipes, Galvanised Drainage Pipes etc. Today, plastic drainage pipes are preferred over metal ones due to their features.
Here are some things to consider when choosing a drainage pipe,
- Size: Drainage pipes come in different sizes. When choosing a drainpipe, size matters. A larger diameter pipe will allow water to flow faster through it. This means less clogging and fewer trips to the plumber. However, large diameter pipes are heavier and require more material to construct. If you plan on installing a bathroom sink, then a smaller diameter pipe will be sufficient. A 1 inch pipe is usually recommended. You need to choose one that fits your project.
- Material: There are many different types of materials used to make drainage pipes. Some are made out of metal, while others are plastic. Plastic and galvanised steel pipes are cheaper alternatives. They are easier to install and are much lighter than copper pipes.
- Installation: Drainage pipes are installed using either a trenchless method or a traditional method.
- Durability: Durability is another factor to consider when choosing a drainpipe system. Pipes made of metal tend to be more durable than those made of other materials. Copper pipes are also more likely to last longer than plastic or steel pipes.
- Maintenance: Maintaining a drainpipe system is an ongoing project. Regular maintenance helps prevent problems and prolongs the life of your pipes. Checking the condition of your pipes regularly will ensure that they are functioning properly.
- Cost: Cost is usually the number one factor when choosing a drainpipe. A cheaper pipe might seem like a great deal, but it could break down over time. If you’re looking for a cheap solution, you might find yourself replacing pipes sooner than expected. On the other hand, a higher priced pipe might seem expensive, but it’s likely to last longer. When shopping for a drainpipe, try to find a pipe that fits your budget.
Size of Drainage Pipes
The size of your drainage pipe depends on the amount of water that needs to be drained. The size of your drainage pipe is determined by the following factors,
- Amount of water
- Type of soil
- Location of the drainage pipe
- Number of fixtures draining into the drainage pipe
- Whether the drainage pipe leads to a storm or sanitary sewer
If you’re unsure about what size drainage pipe you need, contact an engineer who specialises in drainage systems.
Application of Drainage Pipes
Drainage pipes play a major role in construction projects. Their application depends on the type of soil, weather conditions, and other factors. They are used in construction, agriculture, mining, water supply, sewage treatment, etc. Drainage pipes are mainly used for disposing of wastewater from homes, office buildings, or industrial areas. A well-designed drainage system is essential to the success of any building project. If the drainage system isn’t properly designed, water could enter into the structure through cracks or holes in the foundation. This can cause costly damage to the building’s interior.
Choosing the correct sort of drainage pipe might take a long time and effort. You may have to modify project drawings or blueprints depending on the substance and style, or vice versa.
