Cost-effective drainage of rainwater and wastewater

The HS^®-Dual Control Chamber DN/OD 800 offers the ability to drain waste water and rainwater separately through one chamber. The waste water is led in an open DN/OD 160 channel through the chamber. The rainwater drainage is carried out through a K 90 branch which is situated below the benching and onto which a blue HS^® pipe DN/OD 160 is attached.

The advantage is that all necessary maintenance works such as CCTV inspection, jetting, cleaning etc are facilitated. The blue riser pipe reaches up to below the BEGU = Concrete Cast Iron Cover. It is well accessible and closed with a screw cap that keeps odours in. This is why the mixing of waste and rainwater is excluded even in the case of backwater or blockages.

Just one chamber cover on the premises

The "two-in-one" principle makes the use of HS-Dual Control chamber very economic. Construction costs remain low and there is just one chamber cover on the property. The channels are arranged in different heights adapted to the situation on site and local requirements. The integrated HS^® VARIOcoupler gives the chamber junction additional flexibility.

The advantages in practice:

• cost-effective solution „two in one“
• easy to carry out maintenance
• mixing of rainwater and wastewater is safely excluded 
• integrated HS^®-VARIOcoupler providing adjustable (up to 11°) sockets
