Manhole Covers & Frames

Through our network of supply manufacturers we offer a comprehensive range of products that are engineered to include standard and optional features that help to improve durability, operator safety, asset security and performance. Manhole covers and frames are used to prevent anyone or anything from falling into the manhole. We can provide manhole covers, frames and gully gratings, with features that are designed to make them durable, safe and easy to install. Locations of where you place your manhole covers has a huge impact on the type of manhole cover required. The appropriate class of manhole cover or gully grate required depends on the place of installation. The various places of installation have been divided into groups numbered 1-6

GROUP 1 (MIN CLASS A15)

Areas which can only be used by pedestrians and pedal cyclists.

GROUP 2 (MIN CLASS B125)

Footways, pedestrians areas and comparable areas, car parks or car parking decks.

GROUP 3 (MIN CLASS C250)

For gully tops installed in the area of kerbside channels of roads when measured from the kerb edge extend a maximum of 0.50m into the carriageway and a maximum of 0.2m into the footway.

GROUP 4 (MIN CLASS D400)

Carriageway/roads-Including pedestrian streets-Hard shoulders and parking areas for all types of road vehicles.

GROUP 5 (MIN CLASS E600)

Areas imposing high wheel loads e.g. docks

GROUP 6 (MIN CLASS F900)

Areas imposing particularly high wheel loads e.g. aircraft pavements

Domestic Wastewater Treatment

For full Environmental Agency guidance on current General Binding Rules see:

General Binding Rules: small sewage discharge to a surface water

Rules for existing and new treatment systems

Use the correct treatment system

You must use a small sewage treatment plant to treat the sewage if youíre discharging to a surface water such as a river or stream. A small sewage treatment plant (also known as a package treatment plant) uses mechanical parts to treat the liquid so itís clean enough to go into a river or stream.

Discharges from septic tanks directly to a surface water are not allowed under the general binding rules.

If you have a septic tank that discharges directly to a surface water you will need to replace or upgrade your treatment system by 1 January 2020. Where properties with septic tanks that discharge directly to surface water are sold before 1 January 2020, responsibility for the replacement or upgrade of the existing treatment system should be addressed between the buyer and seller as a condition of sale.

If the Environment Agency finds evidence that your septic tank discharging to a surface water is causing pollution, you will need to replace or upgrade your system earlier than 1 January 2020. You will usually have to do this within 1 year, although this will be agreed on a case-by-case basis.

Choosing the right sewage treatment and disposal method for your site is essential to ensure effective long term performance, protection of the public health and the environment, and compliance with relevant legislation.

If you do not have access to a main sewer then you would require either a septic tank arrangement that would require sufficient land space for drainage run off to field. If you have access to a water course then a suitably sized sewage treatment plant would be suitable. Failing this then you may have an option to fit a Cesspool.

If you require further guidance on your best option then contact our sales office to guide you through the process prior to ordering

Septic Tanks

(Euro or horizontal shape available)

2800Ltr (up to 4 users)
3800Ltr (up to 10 users)

Pump Stations

When a discharge to sewer mains is required, but to do so by gravity is impractical, a pump chamber system will be needed. Pump station systems are usually bespoke. And can be supplied with single or twin pump arrangement. Please phone our sales office to guide you through the process prior to ordering.

Grease Traps

A range of grease traps are available effectively prevents Fats, Oils and Grease from entering the drainage network or sewage treatment plants. Please phone our sales office to guide you through the process prior to ordering.

Oil Separators

Oil separators are designed to prevent oil and other hydrocarbons from entering the drainage system. They separate oil from water, and safely retain the oil until it is removed, separators should be used in such applications as petrol stations, industrial yards and garages. Please phone our sales office to guide you through the process prior to ordering.

Bypass Separators

Bypass separators are used in low risk environments where there is no requirements to provide full treatment for the flow, for example a car park where the risk of spillage is small. Please phone our sales office to guide you through the process prior to ordering.

Full Retention Separators

Full retention separators are used where there may be a high risk of a fuel spillage, such as vehicle workshops. Please phone our sales office to guide you through the process prior to ordering.

Alarm Systems

For oil separators, wash down units and silt traps, early warning of excessive level of oil, liquid or silt, or when the unit requires emptying. Please phone our sales office to guide you through the process prior to ordering.

Water Management

Water management is extremely important. With ever increasing developments and hard landscaping within our cities less water is able to naturally filter through the soil which increases the risk of flooding. Planning will now often dictate that an efficient water management system is designed into the project.

These may include the use of Storm water Crates, in ground or above ground rainwater harvesting systems, and the use of permeable paving. Many of these systems will also enable harvested water to be used within the building improving the Sustainability of the project as well as long term savings on Water bills. The manufacturers are also willing to provide more detailed information on your build specification. Please phone our sales office to guide you through the process prior to ordering.

Geotextiles & Ground Stabilisation
