Stormwater Solutions: Hydraulic Systems to Prevent Flooding and Damage in Industrial Buildings

Learn about the key components of stormwater systems, their benefits, and the importance of designing them based on the specific characteristics of each industrial building.

In the construction of industrial buildings, stormwater solutions are an essential component to protect the infrastructure, prevent flooding, and ensure continuous operation of the facility. A poorly designed or standardized stormwater system can lead to leaks, structural deterioration, damage to goods, and operational downtime.

Therefore, the design of stormwater solutions must be based on a hydraulic study tailored to the real conditions of each project, taking into account factors such as location, rainfall patterns, roof type, and the building’s operational use.

stormwater solutions in industrial buildings

stormwater solutions are the systems responsible for collecting, conveying, and draining rainwater in a controlled manner. these systems are part of the building’s hydraulic design and must be properly sized according to the project’s conditions, avoiding generic solutions that do not reflect the site’s actual requirements.

each industrial building presents different challenges: designing a stormwater system for an area with moderate rainfall is not the same as designing one for a region with intense precipitation or short-duration, high-intensity rain events.

how do they work?

the system directs water from the highest points of the roof toward gutters and downspouts, then channels it to municipal networks, absorption wells, or storage systems.

to achieve efficient performance, the stormwater study must consider:

• roof catchment capacity
• rainfall intensity and frequency in the area
• required drainage rate based on operational use
• materials resistant to corrosion and wear
• continuous and safe flow during heavy storms
 

main components of the stormwater system

1. gutters or collection channels

installed along the edges or at the center of the roof to collect water and direct it to the downspouts. their design and capacity must be defined based on the hydraulic study.

• prevent overflow on facades
• reduce leaks
• prevent accumulation on the roof
2. stormwater downspouts

vertical pipes that carry water from the gutters to the drainage system.

• made of pvc, galvanized steel, or high-density polyethylene
• can be internal or external depending on the project design
• their diameter and quantity depend on the volume of water to be drained
3. absorption wells and drainage systems

structures that allow water to infiltrate into the subsoil when there is no access to municipal drainage.

• reduce the risk of external flooding
• regulate flow pressure during heavy rainfall
• must be designed considering soil type and its absorption capacity
4. debris traps

elements that prevent leaves, trash, or sediment from entering the system.

• prevent blockages
• facilitate maintenance
• extend the service life of pipes and gutters
5. rainwater storage systems

cisterns or tanks designed to collect and reuse rainwater.

• can be integrated into irrigation, cleaning, or industrial processes
• contribute to project sustainability
• require precise sizing to operate correctly

advantages of implementing efficient stormwater solutions

• prevention of internal and external flooding
water accumulation can halt operations and damage machinery.
• protection of the building structure
prolonged leaks affect walls, slabs, and roofs.
• longer service life of the roof and installations
moisture, corrosion, and premature deterioration are avoided.
• compliance with construction and safety regulations
a proper stormwater study ensures adherence to local codes.
• reduction of long-term maintenance costs
a well-designed system reduces corrective repairs.

 

common challenges when an adequate stormwater study is not conducted

• water pooling in loading yards
• constant moisture in walls and roofs
• leaks that affect goods or electrical installations
• ground settlement due to poor water absorption
• overflow from the roof in loading and unloading areas
• gutter collapse due to insufficient capacity during storms

what is the best stormwater solution for your industrial building?

there is no single solution. the best stormwater solution is the one designed based on a project-specific study, considering location, roof type, annual rainfall, and the building’s operational requirements.

however, the most efficient and safest option is usually the combination of an integrated system for collection, conveyance, drainage, and, when applicable, storage, achieving:

• constant flow without obstructions
• full protection against flooding
• regulatory compliance
• greater sustainability and water-use efficiency

a professional design based on the project’s real conditions ensures that the industrial building can operate safely even during heavy rainfall, protecting the infrastructure and operational continuity.
