Why choose DEHTLET ?
WATER CONSERVATION

The panel shows the water and electricity consumption by an eco-toilet at a scenic spot   in Beijing. Consuming 81.5445 tons of water for 54,363 uses, average of 1.5 litres water consumed for flushing. We can fill up a short course swimming pool in a year!

The amount for water usage in sewage treatment facilities is not take into the account. Assuming each DEHTLET DTC model serves 30 persons per day, we can save more than 300 litres water for flushing in one single day!

Each year, we can save more than 100 tons of water for
only 1 DEHTLET unit!




REDUCE CARBON FOOTPRINT

 
Transport of Toilets & Sewage

Trucking thousands, sometimes millions of litres of liquid waste from one site to the nearest treatment plant or sewer line access point will add significantly to overall transport emissions.


DEHTLET system only needs regular cleaning once a week or even longer. Mini van is used instead of a heavy loading suction truck.

The carbon emission of a suction truck
3 times a week for transportation is 8.4 times* comparing with our mini van.  The carbon emission of the suction
pump is not take into the account.

At the conservation area,  our
service team can simply use the
bike or on foot with a backpack to
do their services.

Apart from the waste, of course the existing portable toilets must be moved to the site further adding to the emissions impact.

DEHTLET is a smart sanitation system. It can be installed at the existing structure or using our easy installation system which is durable and able to  disassemble and reuse; The standard unit of DEHTLET is

free-standing which requires no concrete or laying foundations. It
can be installed on DIY basis within
4 hours.


We reduce more than 60% of carbon emission!

WASTE RECYCLING

The chemicals contained in standard portable toilets cannot completely disinfect human waste and those are highly toxic to humans and the natural systems. The waste can only be disposed to the sewage treatment plant which is a burden to the environment.

DEHTLET use no chemicals which means dry waste & urine can be collected and reused as fertilizer for gardening and planting.

  • no sewage system or septic tank is required. Construction cost could be minimised. ​Free-standing, not fixed to the ground, and its design and structure allow it to be assembled and disassembled many times over.
  • You can use your existing hut or DIY or home improvement retailing company to fit your home design.

  • no heavy machinery or suction truck is required for regular waste disposal or cleaning. It can also be DIY.
For Household

For Authority

Take Hong Kong as an example:

  • Hong Kong as an international city, the sewerage network is currently serving only 93% of the population. The local authority may preferably allocate sanitation facilities at the foot of the mountains or choose chemical toilets which increase the burden of the existing sewage treatment plants. In fact, there are not enough sanitation facilities for hilltop, hiking trails and remote areas.

Every year, Hong Kong people generated about one  billion m3 of sewage. About 17% of the total sewage generated receives secondary biological treatment and it consumes about 90 million kWh of electricity a year for achieving the required higher quality effluent standard.

DEHTLET system does not require water for flushing, and thus, reduce water consumption and the system reduces the quantity and strength of wastewater to be disposed of onsite. It would definitely lower the operating cost for treatment.

MONEY SAVING

For Industrial
By providing a DEHTLET system on your job site, you can reduce the distance employees travel to use a restroom as well as the time employees must spend searching for an alternative facility, as no close toilet has been provided.
