The new construction of the wet filter building in Harlingerland is designed as a building with earth and

Upper floor provided. On the ground floor and upper floor of the processing hall, 6 open filter basins as well as other processing technology will be accommodated.

On the ground floor of the processing building there are toilets and additional technical rooms

(dosing systems, purge air blowers). On the upper floor, in addition to the open filter basins, the

extend over both floors, electrical control and switchgear

Housed. Both storeys are accessed via a staircase in front of it

opened up.

The water-exposed areas of the filter basins as well as the complete base plate

of the processing building will be constructed of waterproof concrete. All other components are

also designed as reinforced concrete elements.

The processing building will have a bypass paved with composite stone pavement, which will be connected to the

the existing forecourt fastening.

The waterworks site is located within water protection zone 2. Due to the proximity of the planned wet filter system to the existing wells and thus to the

designated protection zone 1, the greatest possible protection of the subsoil and thus also of the groundwater from pollution caused by construction operations must be ensured.

It is planned to start the construction work for the construction of the new wet filter system.
