Is your soak pit or sump pit no longer working properly?
If water is pooling around your property, stormwater drains are overflowing, or parts of your section stay wet long after rain, there’s a good chance your soak pit or sump pit isn’t working properly.
Many Hawke’s Bay homeowners are still dealing with stormwater issues linked to Cyclone Gabrielle and other heavy weather events. While surface flooding may disappear once the weather clears, silt and debris can settle underground and affect how well stormwater systems, soak pits, and sump pits work long after the flooding has gone.
If you’ve noticed flooding, soggy ground, or drains struggling in heavy rain, your soak pit or sump pit may no longer be working properly.
What’s the difference between a soak pit and a sump pit?
People often use these terms interchangeably, but they are slightly different.
A soak pit is designed to slowly disperse stormwater into the surrounding ground.
A sump pit collects stormwater and helps move it through your drainage system.
For most homeowners, the important thing is simple: if either system stops working properly, water has nowhere to go.
Sign 1: Water is pooling around your property
Are puddles hanging around after rain?
If water sits around your home, driveway or lawn for days after rain, your soak pit may no longer be draining properly.
This can happen when:
- silt blocks drainage pathways
- the pit becomes overloaded
- surrounding soil becomes compacted
- the system is damaged underground
In Hawke’s Bay, this is something we’re seeing more often following Cyclone Gabrielle and other flooding events, where fine silt has reduced drainage performance.
Sign 2: Your stormwater system overflows in heavy rain
Is water backing up during downpours?
A working soak pit should help manage stormwater during heavy rain.
If downpipes overflow, surface drains back up, or water starts collecting where it shouldn’t, it may be a sign the pit can no longer cope with the amount of water coming through.
Sometimes this points to a blockage. Other times, the system may simply be undersized for current conditions.
Sign 3: Parts of your section never seem to dry out
Is the ground always soggy?
Consistently wet areas can mean water isn’t dispersing underground as it should.
You may notice:
- boggy lawns
- soft ground underfoot
- wet patches near drains or retaining walls
- areas that stay damp even in dry weather
This can be caused by poor drainage, damaged pipes or a soak pit that has gradually filled with sediment.
Sign 4: You notice smells or stagnant water
Stormwater shouldn’t smell
A soak pit or sump pit should drain efficiently.
If water becomes stagnant, you may notice unpleasant smells or visible standing water around drains or collection points.
This can be a sign that water is sitting where it shouldn’t rather than moving through the system properly.
Sign 5: Stormwater problems keep coming back
Are you fixing the symptom, not the cause?
Stormwater problems rarely improve on their own. If the same issue keeps coming back, it is often a sign that the underlying cause has not yet been identified.
If you are repeatedly clearing drains, dealing with flooding or noticing the same wet areas returning after heavy rain, there is a good chance your soak pit or sump pit is no longer working as it should.
In some cases, what looks like a one-off blockage or isolated flooding issue can actually point to a soak pit that is blocked with silt, damaged, overloaded or no longer coping with the amount of water coming through the system.
Getting to the root cause of the problem early can help avoid bigger repairs and ongoing stormwater issues around your property.
Why soak pits fail in Hawke’s Bay
Stormwater systems can stop working for several reasons.
Common causes include:
- silt build-up from Cyclone Gabrielle or flooding
- blocked or damaged stormwater pipes
- tree root intrusion
- ageing infrastructure
- poor drainage soils in some areas
- systems that are no longer large enough for heavier rainfall
In Hawke’s Bay, extreme weather events have highlighted weaknesses in older stormwater systems that may have previously seemed fine.
Can a soak pit be repaired?
Depending on the issue, a soak pit may be able to be cleaned, repaired or upgraded. In other situations, replacement may be the best long-term option.
The right solution depends on what’s actually causing the problem. In some cases, the soak pit itself is the issue. In others, the real cause may sit elsewhere in the stormwater system.

Frequently asked questions about soak pits and sump pits
A soak pit may overflow when it can no longer drain stormwater fast enough. This can happen if the pit is blocked with silt or debris, damaged underground, overloaded during heavy rain or no longer suited to the amount of stormwater your property produces. In Hawke’s Bay, we are also seeing issues linked to Cyclone Gabrielle and other flooding events, where silt has reduced drainage performance over time.
Pooling water around your property can be a sign that your soak pit or sump pit is not working properly. If water has nowhere to drain, it may sit on lawns, driveways or around the house long after the rain has stopped. This can point to blocked drainage, underground damage or a soak pit that is no longer coping.
If parts of your section stay wet long after the weather clears, it may be a sign that stormwater is not draining properly underground. A blocked or failing soak pit can stop water dispersing as it should, leaving boggy areas, soft ground and persistent wet patches.
Yes. Flooding can leave behind silt and debris that settles underground and affects how well stormwater systems work. While surface flooding may disappear quickly, stormwater problems linked to Cyclone Gabrielle may take months or even years to become noticeable.
Common signs of a blocked or failing soak pit include pooling water, flooding during heavy rain, bad smells, overflowing drains and areas of your property that stay wet for long periods. If the same stormwater problems keep coming back, it is often a sign the underlying issue has not been identified.
In many cases, yes. Depending on the cause of the problem, a soak pit or sump pit may be cleaned, repaired or upgraded. Sometimes the issue sits elsewhere in the stormwater system, which is why identifying the root cause is an important first step.
If you are dealing with repeated flooding, standing water, soggy ground or drains struggling to cope after heavy rain, it is worth getting the problem checked before it becomes more serious. Identifying the cause early can help prevent bigger repairs later.
