Beginning in the 1870s, Mannheim expanded beyond the city squares. The Schwetzinger Vorstadt and Neckargärten districts were developed. Because these areas were lower than the squares, the first sewers were installed there to discharge wastewater into the Neckar. With the introduction of a central water supply in 1888, a systematically planned drainage system became necessary throughout the city. Frankfurt municipal building official William H. Lindley was commissioned to construct the sewer system. To demonstrate the advanced state of Mannheim’s urban drainage, Lindley had a public access point known as the “Fremdeneinstieg” built beneath Breite Straße. Even Grand Duke Friedrich I descended its spiral staircase into the sewer in 1893 and observed a flushing operation from the gallery. During this process, backed-up wastewater rushed through an opened sluice gate and carried away accumulated deposits. Rapid population growth and industrialization threatened to fill the Neckar with sediment. Lindley recommended discharging the wastewater into the Rhine farther north. Since then, wastewater and stormwater from the city squares and southern districts
have traveled through a culvert beneath the Neckar to the Ochsenpferch pumping station. There, the wastewater is raised six meters before continuing under gravity to the sewage treatment plant near Sandhofen.
Seckenheim, 1901: Until 1908, the municipal sewer operations facility was located on the grounds of the former starch factory, now MVV.
