Stormwater Detention Systems
What is a Detention System?
A detention system is a stormwater management solution designed to temporarily store water when infiltration is not possible or not desired. Unlike infiltration systems, which allow water to seep into the ground, detention systems hold water and control its release at a regulated flow rate, preventing flooding and protecting downstream infrastructure.
Why Choose a Detention System?
Heavy rainfall can cause sudden surges in stormwater runoff, leading to overwhelming drainage systems, riverbanks, and surrounding developments. Detention tanks are designed to delay and regulate stormwater discharge, ensuring that water is released at a controlled, pre-determined flow rate that matches the natural, pre-construction runoff levels.

Key Benefits of RainSafe Detention Systems:
Prevents Flooding
Reduces the risk of downstream flooding by controlling peak stormwater discharge.
Regulated Flow Release
Ensures water is discharged at a sustainable rate, protecting surrounding areas from water surges.
Fully Trafficable Design
Can be installed under roads, highways, and heavy-load areas, ensuring functionality without compromising infrastructure.
Optimized for Extreme Storm Events
Engineered to handle 1-in-100 or 1-in-500-year storm events, ensuring resilience and long-term reliability.
Minimized Environmental Impact
Helps maintain natural hydrological balance and prevents erosion or scouring of downstream water bodies.
How RainSafe Detention Systems Work
01
Stormwater enters the detention tank
through a high-capacity inlet system.
02
Water is temporarily stored
in the underground system, reducing immediate discharge.
03
Controlled release mechanism
ensures water exits at a pre-set allowable flow rate, matching pre-construction runoff levels.
04
Downstream flooding is minimized,
preventing stress on rivers, drainage networks, and surrounding infrastructure.
Applications of Detention Systems
RainSafe detention tanks are suitable for:
Urban & Commercial Developments
Managing stormwater runoff in high-density areas.
Hospitals & Critical Infrastructure
Ensuring operational resilience during extreme storm events.
Highways & Roads
Preventing surface water accumulation and traffic disruptions.
Airports
Managing large stormwater volumes while maintaining runway safety.
Schools & Sports Fields
Providing efficient drainage while keeping outdoor areas usable.

Ensuring Compliance & Long-Term Performance
RainSafe detention systems are designed to comply with local and international stormwater regulations, ensuring proper water management that aligns with environmental policies. Our Separation Row technology removes up to 98% of total suspended solids (TSS), preventing sediment buildup and ensuring minimal maintenance.
