A Guide to the Various Types of Drainage Systems

Drainage-Systems

Drainage home systems are crucial for any residential property. Understanding the various types of drainage homes can help you to make a decision on what system is best for your needs. There are a few factors you should consider when choosing a drainage system for your home: the slope of your property, the amount of rainfall in your area, and the type of soil on your property.

There are three main types of drainage systems: gravity, pressure and vacuum, so before you call a company for drain unblocking in London (or anywhere else for that matter) to deal with your situation, refer to this article, so you understand which direction to lead them. Each type has its own specific advantages and disadvantages which will be discussed in this article.

Gravity Drainage System

The gravity system relies on water weight to move water from the roofline down into the ground by way of rain gutters or drains installed at intervals along the roofline that lead to an outlet such as a pipe or drainpipe that empties outside away from buildings, landscaping, storage sheds and other structures. Gravity systems rely solely on natural forces like gravity and rainfall to move water from where it falls to a lower elevation. The end result is the need for roof water catchment tanks that will store rainfall to be used in dry periods.

Gravity systems are inexpensive and relatively easy to install, although they do require a large storage tank or cistern which can be expensive and take up space in your driveway or garden.

Pressure System

The pressure system is a type of drainage system that relies on a pump to move water from the roofline down into the ground by way of rain gutters or drains installed at intervals along the roofline that lead to an outlet such as a pipe or drainpipe, which empties outside away from buildings, landscaping, storage sheds and other structures.

Pressure systems achieve water flow with the use of a pump which is installed at a higher elevation than your home’s rain gutters or drains and is connected by way of piping to your outdoor drainage system. A pressure-assisted sewer system pumps wastewater from homes into larger mains where it enters a treatment plant for processing. A positive displacement pump is the only type of pump approved for use with a pressure-assisted sewer system and must be used downstream of all fixtures to avoid introducing solid particles into the sanitary sewer.

Pressure systems require an electrical supply to power your home’s pump, and it requires regular maintenance such as cleaning your rain gutters, inspecting your irrigation system and cleaning the filter in the pump.

Vacuum System

The vacuum system is a type of drainage system that relies on a pump to move water from the roofline down into the ground by way of rain gutters or drains installed at intervals along the roofline that lead to an outlet such as a pipe or drainpipe, which empties outside away from buildings, landscaping, storage sheds and other structures.

The vacuum system uses a non-clogging pump to lift water up and over the roof edge of your property and deposit it into an open surface such as a pond or garden. A vacuum system is considered one of the most effective methods of water removal; however, it is one of the most expensive systems to install.

So, There You Have It…

Drainage systems are an important part of any home, and it’s essential to understand the different types available and how they work. In this article, we’ve outlined the three most common drainage systems and their properties.

Ensuring your home’s drainage system functions properly will depend on choosing the right system for your needs and knowing how to maintain that system at regular intervals, so you can avoid costly repairs down the road. Each type of system has its own advantages and disadvantages, so be sure to take your choice of system into consideration before making a final decision.
