Storm drain

Drainage and storm water drains are two closely linked systems that work side by side.

Drainage is the natural or artificial draining of certain objects, whereby excess surface water or various liquids are drained away. Drainage can also refer to a system of pipes or channels that help to deal with excess moisture. Meanwhile, storm drains help to channel all those excess fluids away from buildings.

Drainage planning is an important aspect of designing the layout of your site. Drainage is only installed when the permeability of the soil and the water level in the area have been assessed. It is the perfect assessment of these essentials that determines the protection of your site from puddles and of your building and its underground part from abundant moisture and mould.

Most customers install storm drains around their homes because of excess water from rain or melted snow. As mentioned above, it is important to make a thorough survey of your site: to decide whether the excess moisture is caused by groundwater alone, to find out what layers make up the soil and, of course, to pay close attention to the permeability of the ground. The depth of the drainage installation depends on the depth of the water table, but recommendations are that it should be around 1-1.5 m. The length of the drainage pipes depends on the distance of nearby ponds or pipelines, but they should not be laid at the frost line, as the water in the pipes would simply freeze in winter.

A drainage system is usually installed in two ways:

  • Trenching (where a trench about 1-2m wide is dug for installation)
  • Non-trenching

In order to direct rain or snowmelt away from the house, storm drains are installed. It is this system that helps to avoid various damages to the house structure or yard infrastructure, such as sinkholes in the yard, unevenness in the concrete paving, etc.

The installation of storm drains depends in many cases on the preferences of customers. It can be installed in different sections and to different points. Normally, the storm drains on the site are organised into a central storm drainage system, but according to the needs of the customers and the possibilities of the site, they can be drained into nearby water bodies (ponds, rivers, etc.).

The most important aspects of installation are:

  • Rainwater running off the roof is received and channelled by a drainage pipe, preventing moisture from accumulating on the façade of the house or on the unfilled lower floors.
  • In addition, a well with a grate is constructed from the surface of the plot to collect water after rain or snow melt to ensure that the yard dries out faster.
  • All water from the roof goes directly into the well, where a non-return valve prevents the water from flowing back, so that it drains either into the central sewer or into a nearby ditch.

Be confident that our experts are ready to properly assess and analyze your area, determine the nature, amount and indicators of rainfall. In this way, they will be ready to carry out the most important steps for the installation of a quality storm drainage system.

Maintenance of outdoor storm drains:

  • With gutter ends fitted with safety nets, your system will require no maintenance at all.
  • Depending on the type of gutter, it may need to be cleaned of leaves or branches.
  • If you have a sewer with a filtration system, the filter should be cleaned once a season.
