Before certain construction permits are issued, the applicant must certify that a licensed exterminator has been retained.
Sealing the source
solving the problem
- The first step in any mitigation effort is important to find the source of the entrance and seal it off.
- The main source of entrance in a city like New York City is the sewage system, where they come up through the drains.
- Control is key and sealing sewage drains is a major part of the process that can allow us to contain them underground.
- By sealing the drain it allows them to go in one direction, underground, while preventing them to go back up.
- Sewers are ideal for rats due to them being warmer in cold weather and cooler in hot weather.
- It also helps them avoid any human or other animal interaction.
- With garbage disposal systems also dumping bite-sized food into the sewers food is plentiful.
About TDS
goal of device
The device primarily aims to stop rodents and insects from coming out of drains into surrounding areas by sealing the source of the entrance, while still allowing them to get back into the drains. In addition, it also prevents harmful odors from escaping from rainwater and sewage drains, gullies, and manholes. The device is also suitable for retaining swelling sewage water from getting onto the surface.
The device has been working in the sewage system of the Sewage Company Budapest for more than 8 years without any issues.
Installation
The device is adapted to the requirements of the respective manhole cover. The installation can take place with or without a special frame beneath the manhole cover. The fixation is accomplished by the manhole cover itself or with small hooks on the sidewalls/frame. The device can be removed any time from the manhole with a special hook, cleaned & reinserted.
Operation of the Device
The invented device in the dwell position is closed ensuring that rodents, insects, and odors do not escape from the compact sewage system. Under operation the shafts are open, however, water pouring into the drains stops rodents and insects from getting out. The double valve system of the device also impedes wastewater from bursting out onto the surface in case of sewage water swells. The double valve system will open if water or waste water flows in from the surface at the rate of the quantity of the incoming water and will let the liquid into the drains. If the liquid stops flowing in, the shafts close again and will only open under external force.
Device After Settlement
- Blocks the escape of rodents and insects onto the surface and into the environment
- Stops harmful odors from escaping the drain system
- Retains the burst out of waste and rainwater from the sewage system in case of swells and in harbours
Quick Thoughts
- Several models exist according to shut-off types and shapes.
- The device may be produced and placed in any gully or other in- or out-low openings (also in pavement side in-flow openings).
- No advanced skills needed for installation.
- Installation weight of the device is 2, 5-4 kg. Installation weight of the oil and sludge trap is 4-5 kg.
- May be placed into existing systems without hitting the road.
- Installation requires approximately 30-40 minutes for each piece.
- Device is made of plastic and corrosion, base, acid, hydrocarbon and UV resistant.
- No external power for operation is needed.
- Expected time of operation is minimum 30 years.
- The flexible valve shall be checked and replaced if necessary every 10 years.
- Oil trap may be installed under the device.
- This oil trap ensures the collection of oil and sludge tainted by sulphur emitted from vehicles.
- Rodent trap may be installed under the device.
- This rodent trap may collect the rodents getting into the sewage system from the surface.
