Solving Your Stormwater Management Problems

Solving your Stormwater Management Problems

One of the foundations of a successful construction project is solid water management systems. Without one, runoff stormwater will cause the ground to erode and prone the site to flooding and pollutant discharges. So, before your project even starts, make sure you’re attacking the problem at hand and find a sustainable solution for stormwater.  Here’s some common stormwater management problems and solutions you need to be aware of.

The Right Approach to Saturated Soil

Every natural soil is water permeable, but each react differently to the effects of runoff water.

Let’s start with saturated soil. Saturated soil is the most common type of soil. It’s mostly permeable, provides groundwater recharge and treats water naturally. Saturated soil is great for potable or sewage water runoffs. However, it does have a limit. Soil can only filter so much water before it cannot accept anymore and water floods on top of it. At this point, runoff water can cause flooding, carry pollutants and chemicals into natural streams and ultimate lead to land erosion.

The best solution we have for this is by designing a ‘rain garden’. A rain garden is lower than the rest of the land around it, composing of mulch, soil and native plants. The purpose of this garden is to capture, absorb and infiltrate incoming stormwater and prevent natural overflow without resorting to a mechanical system.

How to Take Care of Semi-Permeable Surfaces

Parking lots are just a common example of semi-permeable surfaces. You’ve never seen an asphalt parking lot absorb water, and you won’t in the future. There must be some sort of water retention system in place to manage runoff stormwater. During a high rain period, sewers often overflow and cannot handle excess rainfall, which can cause a flood hazard in parking lots and carry off oil residue and other harmful chemicals into a natural stream.

A retention system prevents the scenario above from occurring. A water retention system holds back excess water before allowing it back into the municipal water system. Made of clean stones inside, the retention system filters out pollutants and other contaminants in runoff water. The size of the retention system depends greatly on both the average rainfall (watershed) and the length of time it must hold the water before it can safely return it for water treatment.

Looking at EPA Requirements

Now more than ever the EPA requirements are demanding a tight grip around water management. There’s a huge concern for pollutants that flood into our natural water supply by runoff stormwater, and so construction projects will often face delays until there is a fit solution in place.

When it comes to finding that solution, our team of Adkan Engineers know how to approach it with diligence. We’ll find a solution that is relevant to the project, and meets EPA requirements, no matter the size of the project. In addition, the requirements aren’t static, they change often. You want a team behind your back that knows the ins-and-outs of the EPA guidelines and make sure that your construction project is always in line with what they want.
