Wet waste removal information

Tardis vacuum tankers are capable of removing liquid waste as per the following information. If there is anything else you'd like to know about septic tank emptying or any associated wet waste please contact our sales team on 0800 731 0589.

Tardis septic tanker filling times

Filling time is dependent on 4 factors:-
  1. Vacuum in tank - Dependent on quality of pump.
  2. Depth from which sucking load.
  3. Fluid properties of load - Water/Sewage/Blood
  4. Pipe diameter

If loading water from a surface lagoon with 28in HG vacuum the best performance that can be expected is:-
            
Loading Times
 1000 galls  2000 galls
*3" dia hose 145 galls/min 7 mins 14 mins 
4"  dia hose 260 galls/min 4 mins 8 mins
5"  dia hose 405 galls/min 2.5 mins  5 mins
6"  dia hose 583 galls/min 1.7 mins 3.5 mins

* Tardis tankers carry 3" dia hose
Tardis tankers use 3" hose to carry out wet waste removal. We can also provide bigger diameter hose on request.  Call our sales team on 0800 731 0589.

1" of HG Vac = 1 foot of lift (filling)
1 PSI of pressure = 2 foot of lift (discharge)

Tanker loading

Septic tanker filling time 2

Vacuum Requirements for solid column lifting

Liquid  "A"  is water with specific weight of 10.0 Lbs/Gal
Liquid  "B"  is sludge liquid with specific weight of 12.0 Llbs/Gal
Liquid  "C"  is sludge liquid with specific weight of 15.0 Llbs/Gal

The vacuum requirements shown are for lifting liquids "A", "B", or "C" the designated height in feet. These liquids are given as an example. Vacuum requirements for other liquids will depend on their specific weights.

Vacuum tankers

Performance limitations

Once there is a vacuum showing on the gauge then loading of the tanker can begin. The speed at which the liquid load flows into the tanker is largely dependent on the following five factors.
  1. The Amount of vacuum in the tank.
  2. The diameter of the loading pipes.
  3. The viscosity of the load.
  4. The density of the load.
  5. The depth from which the load is being drawn
The effective limit on vacuum loading is generally about 8 metres vertically down from the valve at the rear of the tanker to the surface of the liquid being removed. Depths slightly in excess of 8 metres can be tackled if the hose and is alternately pushed in and out of the liquid. This has the effect of reducing the column of liquid in the loading pipe to a series of slugs of liquid separated by pockets of air which aids the lifting effect of the vacuum.

Because the flow rate is proportional to the cross sectional area of the loading pipe the best loading rates are achievable with a full vacuum and a free flowing liquid with a density similar to that of water will be:-

For 3 " (75-80mm) hose it will load at up to 140 gallons/minute (650ltr/min) 
For 4 " (100mm) hose it will load at up to 250 gallons/minute (1150ltr/min)
For 6 " (150mm) hose it will load at up to 550 gallons/minute (2500ltr/min)

For a typical 2000 gallon tanker -
3" hose could load in 15 minutes, 4" hose could load in 8 minutes and 6" hose could load in 4 minutes.

Tardis septic tankers presented with FORS Bronze award!!

Tardis FORS Bronze award

FORS (fleet operator recognition scheme)

What is FORS?

Freight Operator Recognition Scheme (FORS) is an industry-led membership scheme that will change and transform freight delivery in London whether it be a van or a lorry.

The schemes is free and open to any company operating a fleet of vans or lorries in the capital. It will help Tardis Environmental meet the ever increasing demands of our customers and their contractual obligations whilst helping us drive down costs.

FORS offers practical advice and guidance that can reduce fuel consumption and fines such as penalty charge notices.

FORS will help us become even safer, more environmentally-focused and better equipped to deal with the trials of driving in London such as CO2 emissions and management of  collisions should they occur.  Legal compliance is another benefit of membership and we'll be able to demonstrate more fully our commitment to health and safety, managing work-related road risk and improving efficiency.

How did Tardis achieve the Bronze FORS award?

To achieve the Bronze FORS award Tardis Environmental had to meet all the standards laid down by FORS and provide evidence that we have in place a system for monitoring the core KPIs.

Here are the Headings which Tardis provided evidence of to receive the Bronze Award.

  1. Drivers and driver management
  2. EU Working Time Directive and drivers' hours
  3. Driver fitness and health
  4. Speed limits
  5. Mobile phones and in-vehicle Technology
  6. Agency and subcontracted drivers
  7. Vehicle maintenance and fleet management

Here are the benefits of a FORS membership? 


Fuel Advice
FORS will offer use practical ways to help us cut costs and improve the efficiency of our fleet which will help reduce the impact of freight transport on London's Environment.

Tools and guides
FORS tools and guides will help us to better manage fuel usage and monitor and record progress.

Fact sheets
The fact sheet will include topics like:
  • Alternative fuels
  • Engaging staff
  • Preventing diesel spills

Miles per gallon diagnostic tool
FORS have created a simple and easy to use spreadsheet to help us collect and analyse vehicle and driver fuel use data. Which will can be  adapted to our company needs and will feed data into FORS benchmarking system.

Driver licence checks
FORS driver licence check to ensure drivers are on the road legally and reduce time spent checking driver's credentials

Roadside recovery service
FORS members will also have the benefit of AVRO recovery at a discounted pay with no joining or administration fee.

Driver profiling
This will help in improving our drivers standards even more.
