DRAINAGE SOLUTIONS

Each project has its own particular set of design parameters. An elementary solution that solves one drainage problem might not be applicable to another project.

We are registered consulting civil engineers within the State of Texas.

We will analyze the site for volume of runoff and design a discharge system accordingly using acceptable engineering practices and methodology.

We utilize state-of-the-art technology including Geographic Information System (GIS) based design software as well as extremely accurate data which is obtained from government agencies including FEMA, USGS, USDA and other local, state and federal agencies.

There are a number of factors to consider in the design of a drainage system. Among them are:

Gravity.
The lack of a positive outfall that drains by gravity alone might dictate the installation of a pump.

Imperviousness
Imperviousness is calculated as ranging from sand to concrete.  The greater the percentage of impervious surfaces (concrete for instance) the greater the stormwater runoff.  We calculated the percent imperviousness for each project.

Gradient.
Steeper sites drain faster that flat sites. Steeper sites generally require fewer intakes, while flatter sites require more intakes.

Storm Event.
A storm event with a short but intense duration will generate more runoff than a longer but milder storm. All habitable areas should be protected from the inundation expected of a 100-year storm. Other areas can be protected from lesser storms dependent upon the owner’s wishes.

Outfall.
Each project has a different set of parameters including one or more acceptable outfalls which are the lowest points about the property.

Solutions.
Whether using a closed system or an open channel, there are choices in materials and methods, dependent upon the required solutions.  One project might require a french drain while others require creation of an earthen swale or channel.  We focus on the most efficient and cost-effective solution for each project.
