EnviroHorn Oil and Sediment Drain Filter - Holds 19kg / 1 Litre - 100 Micron || SKU: 1000608 || MPN: GRR 10 00 01 EHRN || Brand: Green Rhino®
The EnviroHorn Sediment Drain Filter sits inside a roadside drain (gully) and filters out sediment and debris from site run-off. The sediment and oil is retained and the water is discharged to regulator-approved standards of 100µm.
To use the Envirohorn, the conical filter is placed inside the drain pot and the large square top is cut to size leaving a 6” collar on all sides of the drain aperture. This collar is taped down onto the road using a roll of wide insulation tape. This ensures that all run-off goes through the drain filter. If the Envirohorn fills with silt, simply empty out the collected sediment and refit the filter to the drain. Alternatively, it can be emptied while in situ by simply scooping the sediment out.
The Envirohorn is capable of collecting 19kg of Sediment before it needs emptying to be reused. Additionally this variation of the filter retains up to 1 litre of oil, once the hydrocarbon indicator becomes a dark blue then the filter is full of oil and will need to be replaced rather than reused.

Firewater Runoff - CIRIA (736)
Fire water runoff refers to the excess water used during firefighting efforts, which can pose significant environmental risks. The water used to combat fires can carry pollutants and hazardous materials, potentially causing harm to the environment if not managed properly. It is crucial to control and contain fire water runoff to prevent pollution and protect surrounding ecosystems.
Business owners are responsible for managing fire water runoff and must have a Fire Prevention Plan in place to address this issue. This plan should outline procedures for collecting, containing, and safely disposing of fire water in case of emergencies. Compliance with regulations such as CIRIA (736) is essential to prevent environmental accidents and ensure safe management of fire water runoff.
To effectively manage the risks associated with fire water runoff, it is important to conduct a thorough assessment of the premises and identify potential contamination sources. Implementing secondary and tertiary containment measures, such as blocked drains or containment areas, can help prevent unwanted water from entering drainage systems or natural water bodies.
Engaging the expertise of environmental and flood risk consultants can provide valuable support in meeting regulatory requirements and avoiding enforcement actions. These professionals can assist in developing a comprehensive Fire Water Management Plan tailored to your site's specific needs, helping to mitigate liabilities and protect the environment.
Having a clear plan in place to manage fire water runoff is essential for safeguarding your business and the surrounding environment. By taking proactive measures to address this issue, you can minimise financial risks, legal issues, and environmental damage, ensuring a sustainable future for your operations.

Sewage treatment plants, cesspools, septic tanks, pumping stations and grease control systems in Scotland.
An IBC/ cesspool is simply a single-chamber storage tank with no outlet.
The tank is usually very large (as it has to contain all waste water & sewage) and often made from concrete, brick or grp. The only way to dispose of the waste is by hiring a licensed sewage contractor to remove the sewage for off-site disposal.
The use of cesspools is no longer an option in most instances and new installations are banned in Scotland.
IBC/ Cesspools are simply storage tanks, often underground, and hold untreated sewage.
There is no treatment process in IBC/ cesspools and are generally used when it's not possible to pump wastewater to a mains sewer, the ground conditions aren't suitable for the effluent to soak away, or, where there's no watercourse for treated waste to be discharged to.
They can be good option on temporary sites or those that don't produce much waste, and because they are completely sealed, they're also good for environmentally sensitive sites, where even treated effluent could be a pollution problem.
Wastewater needs to be tankered away regularly, which is where we come in. Your job is to simply check the sewage levels and give us a a quick call when the tank's almost full. it is recommended that you check your cesspool at least once a fortnight. If a full tank isn't emptied it will overflow and you'll notice unpleasant smells, drains backing up, and pools of waste appearing around manhole covers. This kind of pollution can lead to prosecution and hefty fines.
A septic tank is a multi-chamber storage tank allowing liquid (effluent) and solid waste (sludge) to separate, the effluent flows out of the system, usualy in to a soakaway.
Sewage enters a settlement chamber, allowing solid waste (sludge) to sink and the liquid (effluent) to rise to the surface. the surface liquid makes contact with oxygen and the organic matter starts to breakdown biologically. While this liquid (effluent) still contains sewage it is in small enough particles to be carried through the discharge outlet and into the ground (soakaway).
Only partial treatment takes place in septic tanks, and the treated effluent is often low quality and smelly.
Wastewater leaves your property via the plumbing system, and enters the septic tank. Here, gravity separates solids and liquids. the heavy solids (known as sludge) build up at the bottom of the tank, while lighter greases and oils, or scum, float to the top of the liquid layer. Micro-organisms begin to break down the contaminants in the liquid, which are naturally present, partially treating the wastewater. This process generates natural gases, which are released through installed plumbing vents.
The liquid in the tank (called effluent) flows into a soakaway system. This will usually be a series of pipes, set underground in a bed of crushed rock, that allow the effluent to seep slowly into the ground. The rock acts as a filter, while natural bacteria helps break down the waste even further.
At least once a year, you'll need to arrange for your septic tank to be desludged. This keeps your tank working efficiently and helps prevent irreversable damage to your soakaway.
Every septic tank system is designed to handle a certain volume of waste. If more people are using the tank, you might need to have it emptied more often, or increase the size of the tank or soakaway to cope with the extra usage.
If you don't have your tank desludged regularly, sludge builds up which means there's less space for new solids to settle. The new sludge would then get carried through the system in to the soakaway, which will cause irreversable damage called 'blinding' and will block the soakaway; making the whole system ineffective. You'll know you've got a problem when:-
A sewage treatment plant is a sewage-works system that converts raw sewage into water (effluent) and solid waste (sludge). These ‘packaged’ plants come in all shapes and sizes but treat the waste using the same principles - combining oxygen and food (organic waste) to speed up a natural biological breakdown.
All treatment plants need routine maintenance to keep them working at their optimum levels but treat them right and they are an environmentally friendly way of solving an off-mains drainage problem when a pumping station is not possible.
Sewage treatment plants create an artificial environment to speed up the natural process of breaking down the pollutants in sewage. The treated effluent can then be safely discharged into a local watercourse or soakaway system.
There are three main process types:-
Solid matter (sludge) separates from liquid waste and settles at the bottom of the primary settlement tanks, while lighter material forms a layer of scum on the top of the liquid. Sludge and scum need to be removed regularly. If it's not removed, the sludge will build up and eventually carry over into the secondary treatment stage, where it could interfere with the biological process, block the biological filter or pollute the watercourse or soakaway.
The remaining liquid is broken down by live, naturally occurring micro-organisms (biomass) until the quality is high enough for it to be safely discharged to a watercourse or soakaway. The biomass is fed with oxygen to speed up the digestion process.
This final stage allows the contents of the humus tank to settle out. Where discharge consent is more stringent, tertiary treatment is likely. This adds significantly to overall process costs (i.e. nitrification units, sand filters and reed beds). Not forgetting the need for more frequent desludging.
If a watercourse is available and you've been given permission by the environment agency, this is the simplest way to dispose of the treated effluent.
Regular tanker visits are essential to prevent sludge and scum building up in the tank. equally as important is having the system maintained by a properly trained engineer.
Day to day you’ll need to keep the system and electrics well looked after – it is recommended that you get into the habit of inspecting the plant every day to check everything’s working properly. Its crucial the electricity supply is never turned off, as this will stop the treatment plant from working.
Your sewage treatment plant should be desludged and serviced at least once a year. However, each system is different and you should always arrange a desludge and service inline with the manufactures recommendations. This will ensure your sewage treatment plant is in proper working order and that your not breaking the law.
If you pollute the surrounding area you could face prosecution and some hefty fines. If the biomass is harmed, it will usually recover with time and patience. But until it does, you’ll have to live with a pretty foul smell. A pump station is a chamber with electrical pumps inside. they are designed simply to move wastewater (or sewage) uphill or over a distance where gravity is insufficient to provide the required flowrate.
Consisting of a chamber with either single or multiple electric pump units, the pump station is tailored to site conditions, automatically monitoring and maintaining a specific flow of wastewater over a certain length and height. pump stations are the most environmentally friendly option available if your property is within 30m of a mains sewer. Alarms are often fitted to warn of any blockage or failure.
If the mains sewer is above the level of the property, you'll need a pump to raise the waste to the required level. Here, we'll install a chamber below the level of the house. waste discharged into the chamber is then automatically pumped out in to the sewer. Pumped mains need to be serviced, desludged and jetted regularly. some debris will build up in the bottom and sides of the chamber, so you'll need us to come and clear it from time to time. We'll also jet-wash the chamber to remove any build-up on the walls, float controls ans the pump itself.
An alarm can alert you of any problems, but if you don't have one fitted it's best to take a quick look at the chamber every day. The electrics and mechanics will need to be kept in good working order too.
If you don't get the sludge/ debris removed, solids and grits can build up in the chamber and cause damage to the pump - it's essential for keeping the pump and float switches working properly, and if the equipment isn't services regularly, the pump itself could fail - which can be an expensive replacement and may involve a number of emergency tanker attendances.
The pump chamber usually holds 24 hours' worth of waste, after which waste will either overflow or back up to the property.
If you have a sewage treatment plant or septic tank, you’ll probably have a soakaway system which takes the treated effluent from the tank and disperses it into the ground. The most common way of doing this is to use a herringbone layout of rigid, slotted pipework surrounded by drainage stone.
Your could also have a reed bed is a product often specified in order to obtain an even higher level of water quality of a treatment plant before it seeps out into the surrounding land or watercourse.
Soakaways have a limited lifespan which is heavily affected by the quality and volume of effluent dispersed through it. Typically soakaways last up to 10-25 years. the main cause of soakaway failures failing to have regular desludges carried out on your septic tank or sewage treatment plant, which allows untreated waste to flow in to the soakaway and causes a binging effect on the surrounding crushed rock preventing the soakaway from working correctly, this is irreversible.
Fats, oils and grease (fog's) can create big problems for your business, left unchecked, and land you with some pretty hefty fines - as well as bad publicity for your business.
Grease traps are equipment used to treat the wastewater produced by kitchens and food processing areas. The waste usually contains a mixture of fog (fat, oils and grease) that has lesser density than water and therefor floats on the surface of the water. Grease trap helps in the separation of such fog particles from the wastewater and prevent them from flowing through the drainage pipe.
Separated fats, oils & grease are retained inside the grease trap by a series of baffled chambers and the solid food waste is contained by the internal strainer basket whereas the cleaner 'grey' wastewater passes through the separator via a submerged outlet to the main drain.
Monthly visits are essential and are also a legal requirement to prevent fats, oils & grease from entering the public drainage network. Most system also have filters that require periodic replacement.
