Tankered Waste support

Under the regulations laid out by the Environment Act, businesses are obliged to ensure that waste is disposed of safely, with no danger to people or the environment.

Tankered waste is liquid waste that is unsuitable for discharge into the public sewer system, or waste that is received by us from tankers that service areas without a connection to the public sewers. This might include waste from septic tanks, cesspools and chemical toilets.

Our tankered waste teams have years of experience in ensuring that all waste is responsibly dealt with. All our industry leading facilities, the two largest being at Howdon and Bran Sands, hold EA permits stating they can treat cess and septic waste, and do so responsibly and with exemplary eco-friendly credentials.

Under the regulations laid out by the Environment Act, businesses are obliged to ensure that waste is disposed of safely, with no danger to people or the environment. For businesses that work in areas such as manufacturing, construction, or industries where waste water might contain chemicals or organic matter unsuitable for the public sewers, it is important to know that your tankered waste is being dealt with by government approved, experienced sewage treatment centres that are environmentally focussed.

Our sewage treatment centre at Bran Sands, Teesside, is industry leading in its sustainable approach to waste treatment. Using anaerobic digestion, the liquid waste is transformed into energy rich biogas, which is used to power the facility, and agricultural fertiliser. Using this method, the centre has achieved not only a reduction in carbon emissions, but a 90% reduction in biogas consumption and a 50% reduction in imported electricity. This reduction in the operating costs of the facility means that our customers’ bills are protected, and we are able to offer a cost effective and eco-friendly waste water treatment solution.

Cess & Septic Tankered Waste

Businesses have a responsibility for ensuring that liquid waste is dealt with safely and sustainably. Our sewage treatment centre at Howdon, Tyneside, is industry leading in its sustainable approach to cess and septic waste treatment, and offers a cost-effective and environmentally friendly option.

Where waste cannot be discharged into the public sewer systems, sending cess and septic tankered waste to EA permitted and approved sewage treatment facilities ensures that waste is dealt with securely, legally and with a focus on sustainability.

Under the regulations laid out by the Environment Act, businesses are obliged to ensure that waste is disposed of safely, with no danger to people or the environment. It is important to know that your tankered waste is being dealt with by government approved, experienced sewage treatment centres that are environmentally focussed.

Our sewage treatment centre at Howdon uses advanced anaerobic digestion (AAD), which is where the liquid waste is transformed into energy rich biogas. This method produces 50% more biogas than conventional anaerobic digestion, leaving the Howdon plant energy self-sufficient with excess energy exported into the grid.

Between the Howdon plant and our facility at Bran Sands, Teesside, all of Northumbrian Water’s sludge is now used to produce energy, allowing us to offer a cost effective and eco-friendly waste water treatment solution.

Cess & Septic Tankered Waste Regulations

Under the regulations laid out by the Environment Act, businesses are obliged to ensure that waste is disposed of safely, with no danger to people or the environment.

Tankered waste is liquid waste that is unsuitable for discharge into the public sewer system, or waste that is received by us from tankers that service areas without a connection to the public sewers. This might include waste from septic tanks, cesspools, chemical toilets.

Our tankered waste experts have years of experience in ensuring that all waste is responsibly dealt with. Our industry leading facility at Howdon holds an EA permit stating they can treat waste, and do so responsibly and with exemplary eco-friendly credentials.

The ‘Power from poo’ production at Howdon, more formally known as Thermal Hydrolysis Advanced Anaerobic Digestion (AAD), started in 2012 with the company generating electricity. Three years later, this was followed by the production of gas for the National Grid, meaning customers were now cooking on poo too.

The Howdon plant is the company’s largest sewage treatment works and treats up to 12,000 litres of wastewater from customer homes and businesses every second. Its £8 million gas to grid plant is the biggest of its kind in the industry.

The industry-leading ‘Power from poo’ process has transformed sewage sludge from being a waste product that needed a lot of energy to clean up before it could return to the natural environment, into a fuel being used to produce green energy. The innovative process is cutting the company’s annual operating costs of around £9 million and delivering a significant cut of more than 20% in the company’s carbon footprint.

The Thermal Hydrolysis AAD process involves pre-treating the leftover sludge and heating it in something similar to a giant pressure cooker to around 165 degrees Celsius under six bar of pressure. This process destroys any pathogens and breaks down the cell structure, which is then fed to billions of bacteria in giant digester tanks, making it easier for them to eat.

As the bacteria eat the sewage sludge, they release biogas (methane and CO2), which is similar to a person burping and letting off wind. These gases are collected in huge 11-metre diameter sized golf ball-like biogas storage bags, before being fed into a high pressure water wash gas clean up system where the methane and CO2 are separated.

The gas to grid process has a higher financial return than electricity generation and was introduced as it is more efficient than CHP electricity production due to the amount of heat energy losses from the gas engines while creating electricity.

Septic/Cess Waste – Sustainability and Environmental Impact Statement
In March 2020, the Environment Agency published their strategy for safe and sustainable sludge use. In it, the Agency reiterated their position that the most sustainable option for treated sewage sludge is to recycle it to agricultural land as a fertiliser. It provides beneficial amounts of organic matter and nutrients to the soil. This also fits into the government’s strategy as set out in Defra’s 25 year environment plan.

At the same time, the EA also wishes to end the practice of spreading untreated septic tank sludge to land. Although the water industry voluntarily ceased spreading any untreated waste several years ago, it is still possible to spread septic tank waste under the Sludge Regulations. The new strategy will bring an end to this regulatory regime and all treatment and spreading will be brought into line with the Environmental Permitting Regulations.

The safest and most economical way of treating septic, cess and toilet waste is to import it into a regulated sewage treatment works such as Howdon or Bran Sands. Here, it will get treated along with the sewage and sludge on site, to not only provide a fertiliser for agricultural land but also to generate biogas which then gets send to the national gas grid for use in domestic properties.

Tankered Waste: Waste Treatment Processes

Our facilities and processes at our waste water treatment works at Howdon are industry leading in their sustainability and eco-friendly approach.

Backed up by a network of satellite centres designed to reduce the transportation costs, the treatment centres at Bran Sands and Howdon generate their own energy by converting the sludge from waste water into energy rich biogas. The solid waste that is left over after treatment is used on agricultural land as fertiliser, which is the Best Practicable Environmental Option and is supported by the UK government.

Annually treating 40,000 tons of tankered waste, the treatment centres use a combination or thermal hydrolysis and anaerobic digestion. Thermal Hydrolysis is a process in which sludge is pressure cooked, and then rapidly decompressed. This process sterilises the sludge and also improves biodegradability, which means that the feed rates of the digesters can be doubled, leading to maximised energy production.

Anaerobic digestion is a process in which microorganisms break down the sludge in a sealed container without any oxygen present. The microorganisms convert the natural material into various gases, which when combined produce energy rich biogas.
