Gully Emptying with Tardis

It’s that gully emptying time of year again.

Autumn is now in full swing, the leaves are turning from green to autumnal colours and falling off the trees. Even though the autumn leaves are pretty, mixed with the rain water from the typical British wet weather, without prior planning this could then result in havoc. With building site road gullies, car park and street gullies becoming blocked.

leave_ blocking_drain_iStock

If the gully becomes blocked it can then cause flash floods in heavy rain situations as the rain water will not be able to be drained away properly. Gullies are commonly found in a car park locations, if they become blocked this could lead to you being left with a flooded car park. This could then force you to close the car park, until the matter is resolved.

This week at Tardis Environmental we were called out to a company with a flooded car park. See below for the not very pretty pictures of the event. This is a scary example of how car parks can be affected when the gullies become blocked. Unfortunately for this company, that car in the middle was of a visitor!


To avoid something similar happening to your car park and to the high insurance costs associated with this, planning ahead is key. It is advisable to ensure gully emptying is regularly maintained to avoid such circumstances.

Here at Tardis Environmental our gully suckers are specialised tankers. Our tankers have suction specialised gear that will take up the wet waste from hollows and spaces and then take the wet waste and carry it to a suitable disposal point. Specific suction power is often needed for gully emptying as the material being removed can contain bulky debris such as branches and stones.



We at Tardis Environmental provide a nationwide gully emptying and cleaning service. Call our hire desk for your quotation at: 0800 731 0589 or enquire via the website today.

Introducing the Tardis Toilet Calculator

Ok so maybe a bit over the top but we’re excited to share our new interactive toilet calculator with our readers. It’s already proving to be very helpful.

Here at Tardis Environmental we understand it can be a stressful task organising an event or festival, with so many things to arrange. We are already receiving enquires about events for 2016! When organising larger events with a high attendance expected it can become even more confusing.

We are always asked, ‘how many portable toilets do i need?’. In order to make organising sanitation for your event as stress free as possible, we’ve put together a guide that will answer this question for you.

There are a number of factors that can effect the number of portable toilets required, with these factors included in the new toilet calculator. An important influencing factor is the consumption of alcohol, as this will increase the usage and therefore the number of portable toilets required.

The only other information you will be asked is the maximum attendance of your event and the duration of your event (measured in hours).

We’ve also included a calculator for construction sites.

Click here to take a look and let us know your thoughts.

For further assistance contact our hire desk team on the usual phone number 0800 731 0589.

Don’t forget, we can offer the complete event sanitation service from portable toilet hire, water bowsers and waste tank hire.

Water testing, simple isn’t it?

Clean water is something we take very much for granted in our modern daily lives, but if you give it some thought, a lot of effort goes in to supplying water in volume, that is fit to drink.

You only have to take the recent mayhem caused when Cryptosporidium was discovered in the north west’s United Utilities water supply which required people to boil their drinking water.

Water is complicated stuff, it does after all support life. Fish absorb oxygen from their surroundings. Work your way down the microscopic scale and you’ll find a whole spectrum of odd and unusual creatures that live out their lives in water.

Water sampling

Some are harmful to us if consumed, which is why our drinking water is treated to make it fit for purpose. That fitness for purpose is of course only up to the point of delivery, usually your tap.

If not stored correctly, water can easily spoil just like milk or perishable food.

In large quantities, it is not always practical to keep water refrigerated (one method to stall the development of harmful bacteria).

Water bowsers offer the next best storage alternative, especially if they are approved drinking water vessels and employ WRAS fittings are pre-treated prior to filling and securely closed to preserve the integrity of the water inside.

Providing these conditions are followed you can store drinking water safely for 48 hours and then you need to test it for its fitness for purpose (drinking).

Since we launched our sister website, H2O on site water services earlier in the year, we’ve become pretty busy testing and reporting on water quality.

As well as bowsers, drinking water is often stored in larger vessels such as tankers or even pillow tanks.

Our standard test encompasses the following: Bacteria, Nitrate, Nitrite, Hydrogen sulphide, Sulphate, Total hardness, Total alkalinity, Total chlorine, free chlorine, Chloride, copper, iron, exact PH level, exact temperature. Coliforms and E coli. Quite a list isn’t it?

We also check fixtures and fittings for damage or potential contamination. Inlets and outlets of vessels containing water to be tested are sanitised prior to the test being taken to reduce to “negligible” the risk of cross contamination.

Testing is specifically colour based, with the colour of the sample compared to the calibrated test sheets, calibrated we hear you ask?

Water testing sample

Imagine you have a sheet of card which has colours of test variants printed on it. You’ve been using it a long time. You’ve left it out in the sun a few times. The sunlight has bleached the page slightly.

The colours of your test sheet are no longer a fair comparison.

So, rather like everything else in the clever world of quality control, comparison sheets are in turn compared against a master sheet (calibrated to national standards) and certified as a true match to a specific colour result. The sheet is known as a “correct colour chart“.

Coliforms and E coli tests are a little more involved. A strict sampling procedure is followed to prevent accidental contamination. Samples are incubated at a constant (calibrated) 35 degrees for 24 hours before the test is conducted.

Portable water testing lab

If the sample (which was yellow) is green or blue, those yukky little Coliforms are present.

Testing for E coli involves viewing the sample under UV light (again a measured wavelength or approximately 365mm) Zero fluorescence means no E coli, blue fluorescence indicates the little varmints be there.

Water contaminating E coli must be chlorinated using a set procedure and measure of chlorine, then neutralised to make the water safe for emptying into a public drain.

That’s environmental care. Putting harmless but non potable water back into a biological environment where it will eventually be treated at the water works, once again to be safely delivered fit for drinking to taps and outlets.

Vessels which contained the contaminated water, must be treated and flushed to ensure the contamination is neutralised before being used for drinking water purposes again.

Autumn has arrived

September – as the days grow shorter and the leaves turn a variety of russet shades, it’s only a matter of time before the golden carpet will need clearing up.

Whilst it may look very pretty, leaves can present a variety of hazardous situations especially once they start to decompose. Roads, railways and footpaths can all become dangerous places, which is why Tardis roadsweepers are extremely busy at this time of year.

As well as making a slippery mush on roadways and paths as they rot down, the fallen leaves also cause blockages in drains and guttering, which as the weather turns inclement can create a flood risk.

Tardis Roadsweepers

An ounce of prevention as they say is worth a pound of cure. Good reason to book a Tardis roadsweeper.

With depots strategically placed across the UK, we provide coverage for car parks, construction sites, factory roads and forecourts.

Our roadsweepers feature the following:

  • Single and dual sweep operations
  • High pressure jetting lances
  • Gully emptiers
  • All fitted with reverse-aid cameras

Our roadsweepers are available for both half day and full day hire depending on the work required. To arrange for a sweeping service call our friendly hire desk team today on 0800 731 0589.

For rail welfare servicing call the experts

Here at Tardis Environmental we’re no strangers to railway welfare servicing. A large number of our tanker fleet are fully Crossrail compliant and our reputation in this field already speaks volumes.

When you consider there’s 9788 miles of networked railway in Britain which is pretty high maintenance, with our expertise working in the environment, we are closely involved with railway maintenance companies.

As Europe’s biggest construction project, Crossrail is working towards reducing journey time and easing congestion in London and the South East with the new railway covering 100km stretching from Reading and Heathrow in the West across to Shenfield and Abbey Wood in the East.

You may have read in previous blog posts that a large part of our vehicle fleet is Crossrail compliant, a necessity when working with the Crossrail project but also many other high profile construction projects where more than a cap is doffed to health and safety issues.

Crossrail vehicles carry signage alerting road users especially cyclists and pedestrians, to approach the inside of the vehicle with extreme care. HGVs have under run barriers and Sidescan equipment which senses proximity on the dangerous nearside of a vehicle in motion and provides the minimum of an audible alert in the cab though Tardis vehicles carry a video camera monitoring system so the driver can clearly see any approaching potential hazard. Vehicles which are not equipped to this high specification standard are not allowed to enter or work on Crossrail sites.

Some of the services were offer to railway maintenance companies include tank empties, portable toilet hire, welfare servicing, waste tank hire, portable shower hire, water bowser hire and water fills.

The search for happiness, hydration and health

How much drinking water do we need per day? Good question.

Tardis H2o has the answer.

We all know that good hydration is essential for our health and wellbeing, considering that 70% of the human body is made up of water.

We at Tardis H2o on site are often asked how much drinking water a person needs to maintain a healthy demeanor. The answer is dependent on a number of factors. One of the factors is physical build, a person’s physical activity and the weather can make a difference. A hot humid environment for instance would make you lose valuable fluids through perspiration.

We should take note of what our bodies are trying to tell us and the first signs of dehydration can include a dry mouth, lightheadedness and fatigue. In its extremes chronic dehydration can effect body functions such as the kidneys and lead to muscle damaged.

This is why you will often see during large music festivals, events and even raves, people drinking copious quantities of good old H2o. Water really is the best cure.

In situations such as this the worst thing to do would be drink alcohol which would add to the dehydrative effect.

When you are responsible for a gathering where people may be at risk of dehydration there are a number of options open to provide what people need.

Probably the simplest is bottled drinking water because of its self-contained ease of use. For outdoor events you may consider using a specially prepared drinking water bowser. When we say specially prepared we mean that the vessel and the water it contains meet strict guidelines laid out by the Health and Safety Executive and the Drinking Water Inspectorate. Also fittings such as taps and connectors must be WRAS approved (Water Regulations Advisory Scheme).

Drinking Water Station

Storage of drinking water is also strictly regulated and must not exceed 48 hours in a tamperproof vessel without testing for E-coli as a minimum. Tests should also be carried out every 48 hours afterwards to assure that the water is fit for purpose (drinking).

Water testing

Taking into consideration these factors, a rough guide as to how much a person should drink to maintain hydration, 2 litres per day (approximately half a gallon) is the amount advised.

However one should take into account the physiology of the individual. There are no hard and fast rules, just general advice.

The body has many mechanisms for alerting an individual to its needs; thirst being one of them in this case. Taking into consideration what has been said thus far, you can begin to calculate the amount of wholesome drinking water you will need to keep people happy, healthy and hydrated with an idea of how you will store it too.

Moving to the extreme, Tardis H2o on site have provided a tanker filled with 16,000 litres of drinking water and a special dispensing station in recent weeks though our maximum current capacity is a whopping 32,000 litres, enough to swim in let alone drink.

If you have to provide wholesome drinking water, talk to Tardis H2o on site and get the very best advice and service.

Portable Toilet Troubleshooting Guide

Very occasionally, a few problems occur when using portable toilets. We’ve put together a quick guide to help you get them back up and running as soon as possible.

Safety Warning

When you open the toilet unit, you are working in an unsanitary environment. Please ensure you wear appropriate PPE before engaging in even the most minor maintenance operations.

Common problems encountered with portable toilets and how to troubleshoot them.

If the toilet won’t flush properly, lift the lid on the waste tank.

You will see a 1″ pipe with a plastic mesh bag hanging from the gusher pump. It is fastened to the pipe by a jubilee clip.

Occasionally, the pipe assembly will become loose. Affix this by pushing the pipe and the bag on the underside of the pump.

If the pipe is still fixed in place, check for splits. If a split is discovered a new pipe and mesh bag will have to be ordered/supplied.

Portable Toilet Troubleshooting

Less common – If the pipe and bag are in good working order, check below the gusher pump for the condition of the black circular tubular diaphragm. If this is damaged, a Tardis engineer will be required to repair it.

Less commonly, with heavy use, two other issues occur. The toilet paper can cause the filter to become blocked. One sign of this is the flush handle becoming stiff to operate. If this happens, you will need to call a Tardis engineer to repair the problem.

If the flush handle has been operated aggressively, the mechanism may snap. The flush handle will move around with no resistance and the flush will not operate. In this instance, you will also require an engineer to repair it.

Very occasionally, the nozzle shown below can become blocked. The best solution if this happen, is to clear it with a jet lance.

Lancashire drinking water supply

You may have seen in the news the warnings issued by United Utilities about drinking water safety in the north west of England, affecting areas including Blackpool, Preston, Chorley and other surrounding districts, when the bug cryptosporidium was detected in drinking water last week.

Stand pipesThe official advice from the water authorities has been to boil water before drinking which is good advice for any water stored under uncontrolled conditions.

Water testing

Tardis Environmental stepped into the breach with emergency drinking water deliveries, one tanker into Blackpool due as we write.

water tanker at twilight

Our H2O division is ever ready for situations such as this, with supplies of quality assured wholesome drinking water which can be delivered in bowsers (towable and static) or for bulk situations, in tankers like shown in the photos.

Pallet of drinking water

Smaller or domestic requirements can be catered for by the provision of pallets of bottled drinking water available in a range of sizes from 330ml to 1.5 litres.

Where water safety is suspect, we provide water testing services for E coli and Legionella as well as a range of water hygiene services such as welfare cabin testing and cleansing and bowser cleansing all fully documented and to Health & Safety guidelines.

Out and about with Tardis…

Jon, one of our stalwart tanker drivers has been busy with his camera – he gets all the best locations!

Last weekend, Saturday 1st August, was the Leicester Caribbean Carnival. We delivered a mixture of portable toilets and urinals to the event.

Jon took some cracking pictures, though he wasn’t involved in the carnival action (he’s put away his Carmen Miranda outfit until next year), he has a job to do after all.

Last week he was despatched to Edgbaston Cricket Ground in the shiny new MAN Euro 6 tanker with 2500 gallon waste capacity and 1000 gallon clean water capacity. (See the blog we posted last week!)
