ناودان

a vertical pipe attached to a building which carries away rainwater from the roof to the ground

What is a "downspout"?

A downspout is a pipe or tube that carries rainwater from a building's gutter to the ground or a drainage system. It is usually attached to the side of a building and directs water away from the foundation to prevent flooding or damage. Downspouts are often made of materials like metal or plastic and can be shaped in various ways to fit the building's design. Proper installation and maintenance of downspouts are important for effective water drainage and to protect the building's exterior.

What is a "sewer"?

A sewer is an underground system of pipes that carries waste, stormwater, or other liquid waste away from homes, buildings, or streets to be treated or disposed of. It helps prevent flooding, manage waste, and protect public health by directing waste to treatment facilities. Sewers can vary in size and design, ranging from small residential pipes to large city-wide systems. Maintenance and proper functioning of the sewer system are crucial to prevent blockages, leaks, or contamination.

What is a "cesspit"?

A cesspit is a large, sealed container or pit used to collect and store waste, particularly sewage, from a building or household. It is typically found in areas without a direct connection to a sewer system. Cesspits are designed to hold waste until it can be removed and disposed of properly. Unlike septic tanks, cesspits do not treat the waste but only store it, requiring regular emptying by a waste management service to prevent overflow or contamination.

a large congealed mass or blockage in a sewer system that is primarily composed of fats, oils, grease, and non-biodegradable items that have been flushed down drains or toilets

What is a "fatberg"?

A fatberg is a large, solid mass formed in sewers, created by the buildup of fat, grease, oil, and non-biodegradable items like wet wipes, diapers, or sanitary products. These materials stick together and block the flow of waste in sewage systems, often causing significant plumbing issues or even complete blockages. Fatbergs are typically found in urban areas where cooking oil and household waste are disposed of incorrectly by pouring fats down the drain. They can grow to massive sizes and are difficult and costly to remove.

What is a "gutter"?

A gutter is a long, narrow channel, usually made of metal, plastic, or other materials, that is attached along the edge of a roof. Its main purpose is to collect and carry away rainwater that flows off the roof, directing it away from the walls and foundation of a building. This helps prevent water from causing damage to the structure, such as eroding the foundation, staining the walls, or flooding the surrounding area. Gutters are commonly connected to downspouts, which lead the water down to the ground or a drainage system.

a point or location where water or another substance is discharged or flows out from a system, such as a drainage system, sewer, or wastewater treatment plant, into a body of water or the environment

What is an "outfall"?

An outfall is the point where water or waste flows out of a system, such as a pipe or drainage channel, into a larger body of water like a river, lake, or ocean. It is typically designed to release treated or untreated water, stormwater, or wastewater safely, preventing flooding or damage to the surrounding area. Outfalls are commonly found in areas where water management systems are in place to control the flow of water and protect the environment. They help direct excess water away from populated areas and into natural water sources.

What is a "septic tank"?

A septic tank is an underground container used to treat and store wastewater from homes or buildings that are not connected to a public sewer system. It collects waste from toilets, sinks, and drains, separating solids from liquids. The solids settle at the bottom of the tank, while the liquids are filtered out and allowed to slowly flow into the ground through a drain field. Septic tanks help prevent pollution and maintain hygiene by safely handling waste, though they require regular maintenance to avoid blockages or overflowing.
