Indoor Drainage

Everyone knows homes have indoor plumbing, but not a lot of people consider where the water goes once you are done with it. In fact, most people probably wouldn’t even know how your home drainage system works. Essentially, each fixture in your home has its own drain line, and those all merge into one central main line which has the required vent to the outside. This is the line that removes the water from the house. Our company can run this handle installing this system for you, both inside and outside of your home.


One type of indoor drainage system in the basement drain. If you install a drainage system that goes around the perimeter of your basement walls, this will catch not only the water at the most common point of entry, which is through the wall/floor joint, you also capture wall leakage as well.
Another type of indoor drain is a point drain. An example of this would be a shower drain in the middle of the floor. It collects water by forming a gully for the water to run down. Point drains usually connect to the drainage pipes that are underneath the surface.

Another way to drain water is with a sump pump. This typically requires a drain tile, filter, leakage plate and a sump pump. The drain tile, filter, and leakage plate are all installed underneath the foundation, draining to the outside of the building. The sump pump is connected to the system by a circular hole in the floor where the pump is installed to pump the water out through the pipe.

Other obvious types of drains are your everyday household drains: kitchen sinks, bathroom sinks, showers and tubs, laundry systems and the plumbing required to connect the different floors of your building together to all drain properly.

Outdoor Drainage

Once the water has left the home or building it is now being handled by the outdoor drainage system. Normally this empties to another line that runs in to a sewer system that is cared for by the city or municipality. These are usually emptied every 10 years or so. Our company can take care of all your outside drainage needs as well.

One type of outdoor drainage system is a slot drain system. This consists of a straight-lined thin opening where the water runs down into and then that slopes down to a central drain. The slot drain is a good system for parking areas, landscapes, and aquatic facilities.

Another type is a trench drain. This is when there is an actual trench built in the ground, sloping to a main drainage system. This type of system requires grates to cover them, so it usually isn’t efficient unless it is an HDPE drain, which is a lightweight, easy to install system, but even this type still requires grates.

Outdoor Installation

One way to drain water from your house is with an in-ground drainage system that keeps the water away from your home. This type of system is called a French drain. What we will do is dig a trench around your home with the end being at the lowest point. We then place drainage tile inside the trench on top of a layer of crushed rock or river stone and slope it downhill. If the tile is perforated, then a sock sleeve that is made from rot-resistant material is put over the tile to keep sand and dirt from clogging the holes. We then cover the tile with more rock, landscape fabric and topsoil. This is only one way of creating drainage for your home or business.

Another type is a Footing drain. A footing drain is when you install a pipe around the foundation of the building’s perimeter walls on level with the footing. Any water that possibly would have leaked into the home or basement is collected by the pipe and drained away from the building. The drain itself if covered by gravel that is level to the surface of the ground.

There is also a system call the Gutter drainage system. These are the gutters and downspouts you put on your building to catch rain from the roof. It drains the water from your roof into the downspouts and away from the structure. This is commonly used on almost all types of structures.

The last type is a Grading system. This is a simple system that is composed of grading the land down away from your building towards a storm sewer. This is all done within the requirements of the building code.

Septic System

A septic system is an underground wastewater treatment structure that is most commonly used out in rural areas that don’t have access to a city or local town system. This normally consists of the septic tank, a drainage field and a soil absorption field.

A septic system works by having the main drainage line from the building ran into the septic tank, which is usually buried. This tank holds the wastewater and allow the solids to settle down to the bottom (called sludge) and the lighter oil and grease (called scum) to stay floating at the top. A T-shaped outlet allows the liquid wastewater to leave the tank out to the soil drain field while the sludge and scum stay in the tank.

The pretreated wastewater runs out of the outlet and into the soil. Once there, the soil percolates the wastewater, naturally removing harmful bacteria and viruses, and nutrients.

A septic system is installed by finding the best site to bury the tank and soil for the wastewater. Installing a septic system will require approval so our experts will be sure to have all the required permits needed. We then install and bury the tank and outlet pipe, create the leech field (soil) and it is ready to go.
