Stormwater Upgrade.
A stormwater upgrade involves improving a property’s drainage system to manage rainwater efficiently, prevent flooding, and protect structures from water damage. This can include enlarging or replacing pipes, installing new drains or channels, repairing gutters, adding detention systems, or regrading surfaces to ensure proper water flow and compliance with local regulations.
Common Objectives
-
Prevent localised flooding around buildings.
-
Reduce erosion and soil instability.
-
Protect foundations, basements, and paved areas.
-
Ensure compliance with stormwater regulations.
Common stormwater system problems
-
Undersised pipes or pits that can’t handle heavy rainfall
-
Blocked drains from debris, silt, or tree roots
-
Poor falls or incorrect gradients, causing ponding
-
Broken or collapsed pipes
-
Inadequate surface drainage near buildings
-
Overflowing gutters and downpipes
-
Illegal or non-compliant connections
-
Erosion and soil washout around outlets
1
Clear Out
Clearing stormwater pipes by removing blockages such as debris, silt, leaves, and tree roots that restrict water flow. This is typically done using high-pressure water jetting or mechanical cleaning to restore full pipe capacity and prevent backups, flooding, and overflow during heavy rainfall.
2
Repair Damaged Pipe
Fix cracks, joint failures, collapses, or corrosion that allow leaks or restrict water flow. This may involve patch repairs, sealing joints, relining pipes internally, or replacing damaged sections to restore structural integrity, prevent water loss, and ensure the stormwater system functions correctly.
3
Upsize Under Designed Components
Upsizing an under-designed stormwater system means increasing the capacity of the drainage network so it can handle current rainfall demands. This typically involves replacing small-diameter pipes with larger ones, adding extra pits or drains, and upgrading outlets to reduce overflow, flooding, and water damage during heavy rain events.
4
Fall Correction
Adjust the slope or gradient of pipes, drains, or surfaces so stormwater flows naturally toward discharge points. This may involve regrading ground levels or relaying pipes at the correct angle to prevent ponding, backflow, and blockages, ensuring efficient drainage throughout the system.
5
Surface Upgrade
Upgrading the surface by modifying ground or paved areas to improve how stormwater drains. This can include regrading surfaces to create proper falls, replacing damaged concrete or paving, installing surface drains or channels, and sealing cracks. The goal is to direct water away from buildings and into stormwater systems efficiently.
