Option Wastewater EN 1610 - 222607

Wariant:

Menu-guided test sequences for performing pressure tests on wastewater pipes and manholes in accordance with the regulations EN 1610 (Europe), DWA-A 139 (Germany) and DWA-M 149-6 (Germany). This option includes the following menu items in the device: Wastewater Procedure Air : Performing tests with air as the test medium in accordance with the regulations mentioned. EDS2-P 1 bar pressure sensor required. Wastewater Procedure Water: Performing tests with water as the test medium in accordance with the regulations mentioned. The EDS2 level probe is required, and optionally, a smart level control.

Testing of wastewater pipelines

In addition to drinking water pipelines and pipelines for energy supply (e.g. gas, district heating, etc.), wastewater pipelines are also part of the important infrastructure. It is therefore not surprising that every pipeline, sewer or manhole within the wastewater network should be tested for leaks before it is put into operation.

Installation and testing of wastewater pipes and sewers are regulated by the European standard EN 1610, which also requires a final leak test of newly built or renewed wastewater pipelines.

In addition to EN 1610, the DWA as a national association in the field of wastewater (similar to the DVGW) has published the DWA-A 139 worksheet, which specifies further requirements for the construction and final leak testing of wastewater pipelines.

The DWA has issued the DWA-M 149 series of worksheets for the "Recording and assessment of the condition of drainage systems located outside buildings". Part 6 (DWA-M 149-6) describes how the condition of drainage systems in operation can be assessed by means of pressure tests.

All regulations stipulate either a leak test with the test medium air or with the test medium water. Since the procedures differ fundamentally in the process and the measurement technology, the procedures are divided into different menu items in the smart memo.

Option Wastewater EN 1610

Menu-driven test sequences for leak testing of wastewater pipes can be installed via the Wastewater EN 1610 option. Within the menu item, you can select whether the test should be carried out according to the requirements of EN 1610, DWA-A 139 or DWA-M 149-6. The smart memo guides you through the test in an automated process, displays measurement data and progressions, and stores and documents all relevant test data.

The following menu items are installed when the option Wastewater EN 1610 is activated:

EN 1610 Procedure A (air)
The tests with air as the test medium are carried out in accordance with the regulations mentioned. The EDS2-P 1 bar pressure sensor is required for this.
EN 1610 Procedure W (water)
The tests with water as the test medium are carried out in accordance with the regulations mentioned. The EDS2 level probe (plus level probe tripod) is required for this. The smart level control can optionally be used for automatic level control and measurement of the supplied water quantity.

EN 1610 Procedure A (air)

With the help of the appropriate connection accessories, the air procedure can be easily carried out with the smart memo. The compressed air hose is connected (possibly via a suitable adapter) to the bypass of a test seal pocket. Above ground, the hose is connected to the test fitting, to which the smart memo pressure sensor is also connected. The test valve is fitted with suitable connections and ball valves for increasing and decreasing the pressure. This allows all phases of the test to be carried out using the test valve and the smart memo.

EN 1610 Procedure W (water)

The inspection in the Wastewater Procedure Water is usually applied to manholes or pipes connected to a manhole, so that the inspection can be carried out using the level measurement method. With the help of the EDS2 level probe, the water level in the manhole filled with water can be measured and checked. If there is a leak in the manhole (or the adjacent pipe), the resulting drop in the level will be reliably detected by the smart memo.
