What Is a Cesspit? Uncovering the Hidden Truths
What Is a Cesspit?
A cesspit is an underground tank that collects wastewater and sewage without any processing or treatment.
Unlike septic tanks, cesspits do not have a separation process and simply store sewage.
They require regular emptying to prevent solidification and overfilling, with the frequency depending on usage.
Cesspits do not have an outlet like septic tanks, making them a holding tank for wastewater that cannot be discharged.
They are more expensive to install and maintain compared to septic tanks, and annual emptying costs can range from £3,000 to over £13,000.
Key Points:
- A cesspit is an underground tank that collects wastewater and sewage without treatment.
- Unlike septic tanks, cesspits do not separate sewage, but simply store it.
- Cesspits need to be regularly emptied to prevent solidification and overfilling, depending on usage.
- Unlike septic tanks, cesspits do not have an outlet for discharging wastewater.

Did You Know?
1. Did you know that the oldest known cesspit, dating back to around 3,000 BCE, was discovered in the ancient city of Mohenjo-daro, located in present-day Pakistan? This early form of a cesspit provided the inhabitants of the city with rudimentary sanitary conditions.
2. Cesspits, also known as privy pits, were widely used in Europe during medieval times. However, only the wealthy could afford the luxury of having their own personal cesspit, while the majority of people shared communal cesspits, leading to unsanitary living conditions.
3. In the 19th century, the invention of the “earth closet” by an Englishman named Henry Moule offered an alternative to traditional cesspits. The earth closet utilized a mixture of earth and ash to absorb waste, reducing odor and providing a more hygienic solution.
4. It is worth mentioning that cesspits played a crucial role in archaeology, as they often preserved ancient artifacts and remains. The lack of oxygen in these sealed pits can protect objects, such as coins, jewelry, and even human remains, from decomposition, providing valuable insights into past civilizations.
5. Today, cesspits are more commonly known as septic tanks, which rely on bacterial decomposition to break down sewage. However, in areas without access to centralized sewer systems, such as rural communities, cesspits are still in use to collect and contain human waste.
Introduction To Cesspits: What They Are And How They Work
Cesspits, often referred to as cesspools, are underground tanks designed to collect wastewater and sewage without any processing or treatment. Unlike septic tanks, cesspits do not have an outlet for the liquid to flow through. Instead, all the waste is collected and stored within the tank until it is manually emptied. This means that cesspits require more frequent maintenance and emptying compared to septic tanks.
To ensure proper functioning, cesspits need to be emptied regularly, depending on the size of the property and the tank itself. The frequency of emptying can vary from four weeks to once a year, depending on the usage and capacity of the cesspit. It is crucial to prevent solidification and overfilling by adhering to the recommended emptying schedule.
- Key Points:
- Cesspits are underground tanks for wastewater and sewage.
- They do not have an outlet for liquid flow.
- Waste is manually emptied from cesspits.
- Cesspits require more frequent maintenance than septic tanks.
- Emptying frequency depends on property size and tank capacity.
- Prevent solidification and overfilling by following recommended emptying schedule.
Comparison: Cesspits Vs. Septic Tanks
Septic tanks use a treatment process where solids settle and decompose in the first chamber. This separation process allows the liquid to flow into the second chamber, eventually exiting through a soakaway system. Unlike cesspits, septic tanks do not directly collect and store all the sewage. This means that septic tanks do not require frequent emptying like cesspits.
Another significant difference between cesspits and septic tanks is the way they handle wastewater. Septic tanks separate wastewater before it flows to the outlet, while cesspits simply collect and store sewage without any treatment. This distinction results in septic tanks functioning as a more self-sustaining and natural sewage treatment system.
Maintenance And Emptying: Frequency And Costs
Regular maintenance and emptying are vital for the proper functioning of both cesspits and septic tanks. However, there are significant differences in the frequency and costs associated with maintaining these systems.
Cesspits, which directly collect sewage without any treatment process, typically require more frequent emptying compared to septic tanks. While septic tanks only need to be emptied once a year, cesspits may need to be emptied every four weeks to once a year, depending on their capacity and usage. This higher frequency of emptying significantly impacts the maintenance costs of cesspits.
In terms of costs, maintaining cesspits is more expensive than maintaining septic tanks. The annual emptying costs for cesspits can vary from £3,000 to over £13,000, depending on factors such as size, location, and accessibility. On the other hand, septic tanks are generally more affordable to maintain, with average annual emptying costs around £220.
Environmental Impact: Septic Tanks As Natural Sewage Treatment
While both cesspits and septic tanks serve as underground sewage systems, septic tanks offer the additional benefit of acting as natural sewage treatment systems. The separation process within septic tanks allows solids to settle and decompose, while the liquid portion flows out and is filtered through the soil.
As a result, septic tanks aid in the natural treatment of sewage and help plants grow. The organic matter from the wastewater acts as a nutrient for the soil, promoting the growth of vegetation. This natural sewage treatment process reduces the environmental impact, making septic tanks a more sustainable option compared to cesspits.
Importance Of Regular Maintenance: Preventing Blockages And Pollution
Regular maintenance is crucial for preventing blockages, overflows, and pollution in both cesspits and septic tanks. Flushing anything other than pee, poo, and paper down the toilet can lead to blockages and potential flooding, especially in cesspits where there is no separation process.
To ensure proper maintenance, it is important to adhere to the recommended emptying schedule and take precautions to avoid depositing non-biodegradable or harmful substances into the system. By regularly maintaining your sewage system, you can prevent potential environmental pollution and extend the lifespan of the system.
Both cesspits and septic tanks are underground sewage systems, but they have significant differences in their operations and maintenance needs. Cesspits are holding tanks that directly collect and store sewage, requiring more frequent emptying and higher maintenance costs. On the other hand, septic tanks utilize a natural treatment process and have lower maintenance requirements.
Regardless of the type of system in place, regular maintenance is essential to prevent blockages, pollution, and ensure proper functioning of the sewage system.

Frequently Asked Questions
What is a cesspit used for?
A cesspit serves as a storage unit for wastewater and sewage, without undergoing any treatment or processing. Situated underground with a manhole cover for waste collection, the primary purpose of a cesspit is to collect and temporarily contain these substances. Consequently, regular emptying is necessary to maintain its functionality and prevent overflow or other potential issues.
What is the difference between a cesspit and septic tank?
The primary distinction between a cesspit and a septic tank lies in their functionality. A cesspit, unlike a septic tank, lacks an outlet. Essentially acting as a holding tank, a cesspit does not allow for the discharge of wastewater. On the other hand, a septic tank has an outlet and is equipped to separate wastewater before it flows towards this outlet. This ensures that the effluent only discharges into the ground and not into streams or watercourses, as a measure to prevent contamination.
What does a cesspit look like?
A cesspit, resembling a circular brick well, was a common sight in older times. These chambers were typically around 2 meters deep and served as a soakaway for waste. However, despite their intended function, the flawed design of cesspits led to eventual drainage issues, causing the system to back up over time.
Is a cesspit the same as a cesspool?
Yes, a cesspit is the same as a cesspool. Both terms refer to an underground holding tank used to temporarily store liquid waste until it can be properly disposed of. These tanks are typically equipped with a single pipe connection to transport waste from a property into the tank.
