Stormwater runoff occurs when rain and snowmelt flow over land or impervious surfaces (such as streets, parking lots, sidewalks, and rooftops) and does not percolate into the ground. Increases in impervious surface area cause higher flow rates as runoff collects debris, chemicals, oils, sediment, and other pollutants that could adversely affect water quality if discharged to the environment without first being treated.
Controlling and treating runoff is known as stormwater management. While there are many different types of facilities used to control stormwater, two broad categories are Above Ground and Below Ground. Above ground facilities include basins, dry ponds, wet ponds, sand filters, bioretention, swales, etc. Below Ground, facilities are usually unseen and maybe underground pipe storage systems, oil/water separators, sand filters, vaults, or they may be proprietary devices for separating, filtering, or storing stormwater.
To mitigate the risk of the damage to the property and proposed structure, during the construction and post-construction, the professional experts at 3A HYDROTECH SOLUTIONS will:
- Conduct a thorough review and study the available hydrological data and documentation such as site topography, aerial photos of the neighboring properties, to get a better understanding of the surface and underground flow.
- Use the most reliable yet economical technology, materials, and equipment available in the market in our design of the stormwater management facilities.
- We believe that a site visit and interview with the general contractor, property owner and the architect of the record is the most essential task for our designers before starting any design. Also visiting the site during the construction and post-construction is necessary to make sure that all the designed components of the stormwater management facilities are addressed the way it should be.
One of the most important – and simplest – tasks that is needed to ensure stormwater facilities are functioning is to Operate and Maintain the facilities. We suggest annual inspections for owners to ensure they are in compliance with regulations and to avoid surprises.
