Four Types of Stormwater Management Systems

Four Types of Stormwater Management Systems

Reliable is busy building all kinds of stormwater management systems in Maryland!

Your commercial property needs a drainage solution fit for its specific environment. Reliable Contracting is just the company to help you choose the best stormwater management system for your property in central Maryland. Whether it rains or shines, your premises can be ready for a storm with one of the four types of stormwater management systems that Reliable Contracting designs and builds.

Stormwater Management Ponds

Stormwater management ponds can be wet or dry. Wet stormwater management ponds always contain some water, while dry ponds are only full after a heavy rainstorm. These ponds are a reservoir for extra rainwater to prevent flooding and keep pollutants from natural waterways. The sediment settles at the bottom of the pond, and any overflow drains into the nearest stream through a pipe.

Micro-Bio Systems

A micro bioretention pond has layers of natural materials and a gravel base that allows stormwater runoff to filter through it into the ground. Above the gravel layer is soil, stabilized with various water-friendly plantings. It looks very similar to a rain garden. 

A perforated pipe deep underground allows the filtered water to flow into the ground from the gravel layer. By the time the water reaches this depth, it is purified of various debris, chemicals, and the like.

Submerged Gravel Wetland Installation

Submerged Gravel Wetlands

Submerged gravel wetlands are similar to micro bioretention ponds, except that they use gravel cells to filter stormwater runoff. From the surface, the system might look like a series of ponds in grassy ditches or a single marshy pond. It is just another way to keep stormwater from flooding local storm drains and streets and filter out contaminants before the water returns to the wild.

Underground SWM System Installation

Underground Detention Systems

An underground detention system is an arrangement of pipes that temporarily hold stormwater runoff before draining. This system is best for commercial properties with limited space; other types of stormwater management systems require quite a bit of space, up to an acre. Therefore, they typically reside under parking lots or any other manmade structure that still allows for maintenance access. 

Although they do not filter runoff, they do an excellent job of temporarily holding it and controlling quantity. It can also be part of a stormwater management system train that does filter stormwater runoff.
