1. Stoomgemaal Halfweg / Halfweg Steam Pumping Station Marker
De eerste machine van 100 pk werd in 1888 vervangen door een sterkere. Ook werden de schepraderen vergroot. Omdat een grotere stoomproduktie noodzakelijk werd, moest in 1888 het huidige ketelhuis worden gebouwd. waarin vier zogenaamde Lancashire-ketels werden geplaatst. In 1923 werden de stoommachine en de vier ketels vervangen door de thans nog aanwezige installatie. bestaande uit twee Babcock & Wilcox- waterpijpketels en een 500 pk stoommachine. Zowel de ketels als de machine zijn gebouwd door de machinefabriek Gebrs Stork & Co te Hengelo.
Ketel 1 is ontdaan van de ommetseling waardoor nu het inwendige kan worden gezien. Ketel 2 is bedrijfsgereed en wordt nog regelmatig met kolen gestookt, zodat de stoommachine in bedrijf kan komen.
De doorsnede van de schepraderen bedraagt 7.5 m. de breedte 2 m. Per seconde kan 25 m3 water worden uitgeslagen. ofwel 1500 m3 per minuut.

The Halfweg steam pumping station was built in 1852 and operated as a reservoir pumping station until April 20, 1977. The original pumping station consisted of the engine house, with the housing for the scoop wheels on either side.
The first 100-hp engine was replaced by a more powerful one in 1888. The paddle wheels were also enlarged. Because increased steam production became necessary, the current boiler house had to be built in 1888, in which four Lancashire boilers were installed. In 1923, the steam engine and its four boilers were replaced by the installation still in place today, consisting of two Babcock & Wilcox water-tube boilers and a 500-hp steam engine. Both the boilers and the engine were built by the engineering company Gebrs Stork & Co. in Hengelo.
Boiler 1 has been stripped of its brickwork, revealing the interior. Boiler 2 is operational and is still regularly fired with coal, allowing the steam engine to come into operation.
The paddle wheels have a diameter of 7.5 m and a width of 2 m. They can discharge 25 m³ of water per second, or 1,500 m³ per minute, 90,000 m³ per hour, and 2,160,000 m³ per day.
