The British Water Pumping Station in the Tel Afek area of the Yarkon National Park is a significant historical structure from the British Mandate period in Palestine. This facility was part of a broader water supply system that was instrumental in conveying water to Jerusalem. The process began with the collection of water from the Rosh Ha’Ayin springs. This water was then transferred to filtering pools for cleaning, followed by chlorination. Once treated, the water was stored in an underground reservoir and subsequently pumped to Jerusalem.

The British water supply system from Rosh Ha’Ayin to Jerusalem, constructed during the British Mandate period, included multiple pumping stations along its route. This ambitious engineering project, aimed at solving Jerusalem's chronic water shortage, featured pumping stations at Rosh Ha'Ayin (Ras al-Ein), Latrun, Sha'ar HaGai (Bab al-Wad), and Saris, the latter of which was replaced by the Israeli village of Sho'eva, named after the pumping station. The system utilized advanced pumping technology to force water up the mountainside to Jerusalem and was operational until the 1948 War of Independence when it was cut off by the Jordanian Arab Legion.

The physical remnants of this system in the Afek area include the pumping station itself, as well as the sinking and filtering pools, and the chlorination structure. Additionally, buildings opposite the station, which served as offices and residences for the British soldiers who guarded it, are now used by the Israel Nature and Parks Authority. This setup was not only crucial for Jerusalem's water supply but also forms an integral part of the area's history, blending seamlessly with the natural and archaeological significance of the Yarkon National Park.
