Sewage infiltration tunnel 300L, for rainwater, sewerage. ST300

A modern multifunctional infiltration tunnel is a suitable solution for the infiltration of both rainwater and treated wastewater into the ground.
Infiltration tunnels are intended for use in the drainage of rainwater or wastewater from private houses, farmsteads and summer houses. Tunnel covers are not included.

Technical data:
Volume of one tunnel: 300L
Load: 3.5 tons
Height: 500 mm
Width: 800 mm
Length: 1200 mm
Connection diameter: 110/160/200/315 mm
Ventilation connection: 110/160/200 mm
Weight: 11 kg

Each module replaces 32m 110 diameter drainage pipes by volume. Using an infiltration tunnel will save you money on buying gravel and digging. The infiltration tunnel is a cost-effective and efficient solution for the infiltration of treated wastewater into the ground.

Sewage disposal:
Ø septic tank, concrete pits - 2 tunnels per user;
Ø biological treatment plant - 1 tunnels per user.
Drainage of rainwater:
Ø 1 infiltration tunnel for every 30 m2 of roof surface or area from which water is collected.

Infiltration tunnel modules are installed either in one line or in several lines. They can be easily adjusted to the specific conditions and the desired volume. Installation of infiltration tunnels does not require hiring a team of professionals. Thanks to the simple design and light weight of the tunnels, connecting the modules to each other is convenient and the customer can do it himself. The infiltration tunnel module weighs only 5 kg, so it is easy to transport and requires no special tools for installation. This means that the amount of excavation work is reduced, and special equipment for transportation and installation is not required.
Tunnel production technology allows, with proper digging and installation, to withstand a weight of up to 3.5 tons. Tunnels can also be installed under the driving part right next to the house.
The modules of the infiltration tunnel are easy to connect to each other (in a row) and close the ends with covers.

The infiltration tunnels are placed in a pre-dug 90 cm wide pit, which contains a 10-20 cm thick layer of washed pebbles or granite, with a slope of 0.5% to 1%.
It is important to observe the following: limestone and dolomite chips should not be used, because they cauterize.
It must be remembered that the tunnels must be placed with the open part down so that the sewage flows out of them. It should be noted that aerobic purification processes take place in the soil and pebbles, the formation of which is influenced by the presence of oxygen. It is important to create a ventilation system for the infiltration field through a closing well with a perforated cover or to run a ventilation pipe above the surface of the ground, through which air inflow to the infiltration field will be ensured.
