Rainy Season Plumbing: Protect Your Accra Home
Anyone who has lived through a few rainy seasons in Accra knows the pattern. The first heavy downpour arrives, and across the city the same compounds flood, the same yards turn into ponds, and the same toilets start backing up. It looks like bad luck, but it almost never is. The homes that stay dry did a handful of unglamorous checks before the rains — and the homes that flood usually skipped them. Here is the checklist that decides which house you are.
Why Accra Floods the Way It Does
Two things make Accra’s rains hard on plumbing. First, the soil: much of the city sits on heavy clay that drains slowly, so soakaways and yards saturate fast and have nowhere to send the water. Second, the rain arrives in short, violent bursts that overwhelm any drainage that is even slightly blocked. A gully that copes fine in dry months chokes the moment it has to take a real downpour through a half-silted line. The flooding is rarely the rain alone — it is the rain meeting a drain that was not ready.
The Pre-Rains Checklist
Do these before the first big storm, not after.
Clear every gully and yard drain
The outdoor gully traps and yard channels that carry rainwater away are the first things to silt up with leaves, sand and grit through the dry season. A blocked gully has nowhere to send a downpour, so it overflows back across your compound. Lift the gratings, clear the traps, and make sure water runs away freely.
Check the soakaway and septic before they are full
This is the one most people skip and most regret. If your soakaway or septic tank is already near full going into the rains, the first storm tips it over the edge and the whole system backs up into the house. Get it checked — and emptied if needed — before the rains, not during. Septic-tank emptying runs indicatively GH₵400–800 by tank size.
Test that drains flow under load
A drain that trickles fine in dry weather can still fail under a downpour. If a line has been slow, or a gully gurgles, that is a warning — clear it now while it is a small job, not when it is backing up at midnight in a storm.
Look for the small leaks that become big in the wet
Damp seasons expose roof-line, tank and pipe leaks that you tolerated through the dry months. A small leak plus saturated walls is how serious water damage starts. Trace and fix them now (see burst pipe and leak repair) while the weather still lets you.
For Compounds, Flats and Businesses
A single home’s flooding is a problem; a compound’s or a block of flats’ is a much bigger one, because the shared drainage and the soakaway serve everyone at once. If you manage a property with shared drains, the pre-rains check is not optional — one blocked main line floods every unit. Our commercial drainage systems work covers exactly this: surveying, clearing and, where needed, upgrading shared drainage so a compound stays dry through the season.
When the Storm Has Already Hit
If you are reading this with water already rising:
- Stop using toilets and sinks that are backing up — adding flow makes it worse.
- Move valuables and electronics clear of the water and off the floor.
- Keep clear of any socket or board near standing water.
- Call a plumber for the backup; a storm-driven sewer backup is an emergency.
Get Ahead of the Rains
The homes that stay dry are not lucky — they are prepared. A pre-rains drainage check is one of the most worthwhile things you can do for an Accra property, and it is far quicker and easier than dealing with a flooded house.
