Cesspits & Cesspools
Keeping Your Tank Safe and Clean
If your home isn’t connected to the main sewers, you might have a cesspit (often called a cesspool) in your garden. Unlike other systems, a cesspit doesn’t treat the waste or let it soak away into the ground—it simply stores it.
In simple terms: Think of a cesspit as a sealed underground holding tank. Everything that goes down your plugholes and toilets stays in the tank until it is pumped out.

Why Cesspits Need Special Care
Because a cesspit is a sealed container, it has a limit. It doesn’t have an outlet pipe, so if it gets too full, the waste has nowhere to go. This can lead to overflows in your garden or backups in your house.
Regular maintenance is vital to avoid:
- Costly bills: If your tank is leaking or letting in rainwater, it fills up faster, meaning you pay for more pump-outs than necessary.
- Environmental issues: A leaking tank can pollute the surrounding soil and groundwater.
- Health hazards: Overflows are unpleasant and unsanitary.

How ASL Can Help
We cover every aspect of cesspit ownership, from routine emptying to emergency repairs.
1. Emptying & Maintenance – Since the waste has nowhere to go, it must be taken away by a licensed waste carrier like ASL. We offer:
- Scheduled Emptying: We can set up a monthly, quarterly, or annual schedule so you never forget.
- One-off Emptying: Just call us when you need us.
- Emergency Response: If your tank is full or overflowing, our tankers are ready to help.
2. Inspections & Health Checks – Is your tank filling up faster than usual? It might have a crack letting groundwater in, or a surface water drain might be wrongly connected to it. We inspect for:
- Cracks and leaks (watertightness).
- Tree roots growing through the walls.
- Damage to lids and covers.
- General structural health.
This is especially useful if you are buying or selling a property with a cesspit.
3. Repairs & Upgrades – If we find a problem, we fix it. We can replace broken manhole covers, seal leaks to stop groundwater getting in, and repair inlet pipes. We can also install high-level alarms inside the tank to warn you before it gets full, saving you from nasty surprises.
Common Signs of Trouble
You should give us a call if you notice:
- Bad smells in the house or near the tank.
- Wet patches or spongy ground around the cover.
- Frequent filling: If you are emptying it much more often than usual, rainwater might be getting in.
- Toilet trouble: Slow flushing or gurgling sounds.

Who Is This For?
Cesspits are usually found in:
- Rural homes and cottages.
- Properties with poor soil (like heavy clay) where soakaways won’t work.
- Holiday lets, farms, and campsites.
- Commercial sites without mains drainage.
