If safe, take photos while rainwater is moving so the flow direction is clear.
Stormwater drainage
Stormwater drainage help for surface water, yard flooding, channels and downpipe discharge.
Stormwater drainage should move rainwater away from buildings without pushing water into drains, neighbours or weak property areas.
Plumb A Nator helps with stormwater drainage concerns where rainwater pools near walls, gullies overflow during storms, channels block, downpipes discharge badly or paved areas send water toward buildings. This page focuses on practical drainage symptoms, access points and water-flow decisions for domestic and light commercial properties.

Rainwater flow diagnosis
Stormwater drainage starts by watching where rainwater actually moves.
Stormwater problems are often created by surface levels, blocked channels, short downpipe outlets, compacted soil, paving fall or undersized drainage paths. The right solution depends on flow direction, access and where water can legally and practically discharge.
Quick details that help before arrival
Useful details include photos during rain, where water enters, downpipe positions, channel drains, nearby gullies, paving slope and whether the problem affects a neighbour or public area.
Before the team arrives
Record the water path while it is raining if safe.
Stormwater faults are easier to diagnose when the water path is visible. Photos taken during rain often show whether the problem is a blocked outlet, bad fall, downpipe discharge or surface-level issue.
Clear visible leaves
Remove leaves from grates and channels only where it is safe and easy to do so.
Mark the worst point
Note the doorway, wall, garage, patio or gully where water becomes a problem first.
Avoid redirecting blindly
Do not cut channels or redirect water toward neighbours without a proper route.
Focused service
Stormwater issues separated by where the water appears.
This section keeps stormwater content focused on rainwater movement rather than general drain cleaning.
Surface
Yard and paving runoff
Paving and compacted soil can send water toward walls, garages or patios. The fall of the surface and available outlet route must be checked before changing channels.
What to look for: Water running toward doors, pooling against walls or crossing paving instead of entering a drain.
Helpful hint: Photos during the first heavy rain are often more useful than dry-weather photos.
Downpipes
Downpipe discharge problems
Downpipes that dump water at the wrong point can flood flower beds, paving edges, foundations or gullies. The outlet route should be visible and serviceable.
What to look for: Water trenches under downpipes, splash marks on walls or pooling near the base of a building.
Helpful hint: A longer outlet pipe helps only if it sends water to a safe drainage point.
Channels
Blocked channels and grates
Channel drains can block with leaves, sand and roof debris. If the channel is clear but still backs up, the outlet or fall may be the restriction.
What to look for: Water sitting in a channel after rain, debris against grates or overflow at one end of the line.
Helpful hint: Cleaning the grate is not enough if the channel outlet is blocked downstream.
Gullies
Gully overflow during storms
A gully that rises during rain may be receiving too much surface water, may be blocked or may be connected to a route that cannot cope. The symptom must be separated from wastewater overflow.
What to look for: Outdoor gullies rising during rainfall, smells, slow drop after rain or water reaching doors.
Helpful hint: Mention whether the gully rises only in rain or also when fixtures drain inside.
Stormwater routing note
Stormwater should be assessed separately from sewer and indoor waste plumbing.
Rainwater runoff, paving channels, roof downpipes and yard drainage should not be redirected blindly into sewer or indoor waste routes. The practical route depends on the property fall, visible discharge point, municipal stormwater rules and whether the water is surface runoff rather than plumbing wastewater.
Helpful hint
Record where water travels during rain and keep photos of the downpipe outlet, paving channel, gully, boundary wall and lowest flooding point. That evidence helps separate stormwater routing from blocked drains or sewer-line faults.
Stormwater Drainage FAQ
Common questions about stormwater drainage.
These answers are written for practical plumbing decisions, safety and preparation before the team arrives.
What is stormwater drainage?
Stormwater drainage manages rainwater from roofs, paving, yards and surface areas so it moves away from buildings through suitable channels or outlets.
Why does water pool near my wall after rain?
Pooling can come from poor surface fall, compacted soil, blocked outlets, short downpipes or paving that sends water toward the building.
Can a blocked stormwater drain flood a garage?
Yes. If a channel, grate or outlet blocks, water can collect at the lowest point and enter garages, patios or rooms.
Should stormwater connect to sewer drains?
Stormwater and sewer routes should not be treated as the same thing. The correct route depends on property layout and local drainage requirements.
Why does my outside gully overflow during rain?
It may be receiving rainwater, may be blocked, or may be connected to a route that cannot handle storm flow. It should be checked carefully.
Can downpipes cause damp walls?
Yes. Downpipes that discharge too close to walls or foundations can keep areas wet and contribute to damp problems.
What should I photograph before the visit?
Photos during rain showing flow direction, pooling points, downpipe outlets, grates, channels and affected rooms are very useful.
Can stormwater drainage be improved without digging everything up?
Sometimes. Cleaning, redirecting downpipes, improving outlets or adjusting surface flow may help depending on the cause.
Why does a channel drain stay full after rain?
The outlet may be blocked, the channel may not have enough fall, or the receiving drain may be restricted.
Can stormwater problems affect neighbours?
Yes. Redirecting water without planning can push water onto neighbouring properties, so discharge routes must be considered carefully.
Do leaves cause stormwater blockages?
Leaves, roof grit, sand and garden debris commonly block grates, channels and outlets.
Can paving cause stormwater problems?
Yes. Paving with poor fall can send water toward doors, walls and garages instead of safe drainage points.
Is stormwater drainage urgent?
It is urgent when water enters rooms, threatens electrical areas, undermines paving or floods garages during rain.
Can stormwater drainage help prevent damp?
Good rainwater management can reduce moisture around walls and foundations, but existing damp may also need separate investigation.
What is the first step in stormwater drainage work?
The first step is usually to identify the water path, lowest points, downpipe discharge, channel condition and practical outlet route.
