What is a Soakaway?

Soakaway is the technique of encouraging water to be reabsorbed into groundwater systems through measured release. It uses the natural infiltration properties of subsoil to reintroduce water into the environment at a rate and volume that won’t saturate or flood surrounding land. Where ground conditions allow, soakaway systems represent an efficient and reliable water management practice, retaining surface water on-site, recharging groundwater sources and providing treatment as water percolates through soil and gravel.

How often should my Septic Tank be emptied?

Whilst there is no easy answer to this question we can provide advice based on a number of factors including the size of the tank, the size of the property, the method of discharge and the number of occupants. Please feel free to contact us for guidance

What is High Pressure Water Jetting?

High Pressure Water Jetting (HPWJ) has been around for many years for a number of manufacturing and cleaning applications. The use of High Pressure water for cleaning dates back to the mid-1800s when it was used in the mining industry. Much later, in the 1930s, more refined jets of water were used as an industrial cutting solution. Today HPWJ is still mainly used for clearing blockages in the pipe. It is the high pressure that makes the water such an effective clearing solution and the water pressure for cleaning drains is usually between 1000 and 3000 psi or 200 bar.

What is a sewage treatment plant?

A sewage or wastewater treatment plant is designed to treat raw effluent to a better and less polluting quality than a septic tank. Most treatment plants will have a secondary or biological treatment zone that removes the soluble polluting matter by the use of micro-organisms. Then a final section will settle out the solid particles. Note: The selection and sizing of a treatment plant requires specialist advice to ensure it meets the needs of the site or application. Please feel free to contact us for guidance and/or to arrange for us to conduct a no obligation free survey.

What is a grease trap?

A grease trap is a containment tank to capture fats, oils and grease from sink waste to prevent it entering the drain system. Evidence tells us that should fats, oils and grease get into drains as they cool down they solidify and then other debris get caught in the grease which, in turn causes blockages. Grease traps should be cleaned and maintained regularly and the grease waste disposed of to registered waste disposal sites. We strongly recommended that commercial properties where food is prepared should have some sort of grease trap in place. For our domestic customers you can allow the grease waste to cool and then bag it and bin it. Alternatively an ecological solution would be to allow the grease waste to cool add some nuts into the grease and then feed to wild birds especially in the winter time.

Can I set up a regular empty?

Yes, you can choose to have your tank emptied at regular intervals to suit your particular requirements. Please contact us for advice.

Do you need for me to be at home when you visit?

No, just as long as we can access the sewage tank you do not need to be present.

Do you accept card payments?

Yes, we accept all major debit and credit card payments over the phone, by transfer online or you can pay the driver by cheque at the time of the service.

What is a Petrol Interceptor?

Petrol interceptors are installed at commercial and industrial sites and on car-parks to intercept oil and petrol passing through below ground chambers before discharging into a storm water system.

What is a Reed Bed Sewage System?

Reed beds only treat liquid effluent - solids will need to be treated elsewhere, either pumped from the septic tank and treated with the mains sewage, or composted. Reed beds are aquatic plant based systems which allow bacteria, fungi and algae to digest the sewage and clean the water.

What is a Pump Station?

Sewer pumping stations are designed and used to move wastewater to higher elevations in order allow transport by gravity flow. The wet waste ( Sewage ) is fed into and stored in a sealed underground pit, commonly known as a wet well.

What is a Vacuum Tanker?

A vacuum tanker is a truck with a heavy duty vacuum designed to pneumatically load solids, liquids, sludge or slurry through suction hoses.

What is a Drainage CCTV Survey?

A CCTV drain or sewer survey is an accurate way to get detailed look at the condition of your underground drains

What is a confined space entry?

A confined space is a place which is substantially enclosed (though not always entirely), and where serious injury can occur from hazardous substances or conditions within the space or nearby (e.g. lack of oxygen).

What is a Maintenance Contract?

An agreed fixed fee over an agreed period for periodic maintenance of buildings, equipment or plant.
