Cleaning, unblocking, bacteria treatment, construction, repair and septic tank conversion across Greater Accra
Many homes in Accra now use biodigesters instead of traditional septic tanks. They are compact and use bacteria to break down waste — but they are not maintenance-free. Because a biodigester is a small chamber, sludge and silt still build up inside it over time.
When that build-up is not removed, it leads to blocked and clogged pipes, slow drains, bad smells and overflowing manholes. We recommend cleaning your biodigester at least every 1–2 years to keep it working properly.
Toilets take long to drain or need several flushes — a sign the chamber or pipes are filling with sludge.
Water backs up in showers, sinks or floor drains, or the soak-away overflows after rain.
Foul odours around the manhole, bathroom or compound mean waste is no longer breaking down properly.
Bubbling or gurgling sounds in the pipes when you flush or drain water.
Wastewater pooling around the biodigester cover or inspection chamber.
Even with no symptoms, a biodigester that hasn't been cleaned in 1–2 years is due for servicing.

A biodigester uses bacteria to break down waste, so it needs emptying far less often than a traditional septic tank. That is why many new homes in Ghana choose them. But no biodigester breaks down everything: sand, silt, tissue and other material slowly settle and fill the chamber.
Household cleaning chemicals such as bleach and strong detergents also kill the bacteria the system depends on. Over time digestion slows, sludge builds up faster, and the pipes start to block. Regular cleaning plus a fresh enzyme and bacteria treatment keeps your biodigester working the way it was designed to.

A biodigester should be cleaned at least every 1–2 years. Even though bacteria break down most of the waste, sludge and silt still settle in the chamber over time. If it is not removed, it causes blocked pipes, slow drains and bad smells.
Common signs are slow-flushing toilets, blocked or overflowing drains, gurgling pipes, foul smells around the manhole or soak-away, and water backing up into the bathroom. If you notice any of these, call us for an inspection.
