Solids separation system – The premium solution for sewage pumping

Wilo provides the right solution for all your sewage disposal requirements. Based on an extensive product range, pumping stations can be individually planned and assembled. Whether in a prefabricated, concrete or plastic sump – Wilo will work out the most economic solution for you.

With wet well installation, costs are saved above all by the simple construction. The pumps stand directly in the sewage and can be assembled without having to climb into the sump by using a self-coupling system.

With the dry well installation version, the sewage is collected unfiltered in a reservoir. The pumps are located outside the reservoir. This means that maintenance work on the pumps can be carried out conveniently without coming into contact with the sewage. Dry well installation is suitable for uncritical sewage with a low solids content.

This innovative Wilo technology separates the solids from the sewage and holds them back in separate solids tanks upstream of the pumps. Only prepurified sewage comes into direct contact with the pumps on the way to the combined collection space. Once the coarse solids have been eliminated from the sewage using this technique, the sewage is transported by the dry well pumps and pumped out into the collection tank. On the way to the outgoing pressure pipeline, the sewage flows through the solids separation tank, pressing the solids out into the pressure pipeline. Sewage and solids remain in the system. The pumps remain dry due to their location outside the tank. This allows maintenance work on the pumps to be carried out conveniently and hygienically.
