At the beginning of the 20th century, efforts continued to ensure a sufficient source of drinking water for Brno, which resulted in the construction of the so-called Březovské vodovod. In this context, two additional water reservoirs were built on Žlutý Hill in 1910. However, burnt bricks were no longer used as a structural element, but the entire structure of the giant reservoirs was built of reinforced concrete.
This youngest reservoir consists of two adjacent tanks connected by a large valve chamber. The northern tank is almost square in plan, measuring 35 x 30 m, while the larger southern tank is rectangular, measuring 45 x 30 m. The height of both tanks is about 6 m. The concrete tanks are vaulted by a system of cross vaults supported by 40 (larger tank) and 25 (smaller tank) prismatic piers on plain, comical-needle-shaped footings. The flat bottom of the tanks is divided by right-angled drainage channels.
Like the previous two brick water tanks from the 19th century, these two concrete tanks were also used for the pisárek water supply and also only for drinking water. They also ceased operation in 1997 and have been empty since then. However, they are currently the subject of a search for their new function. Making the reservoirs accessible is one of the few possibilities to reuse these valuable historical and technically interesting spaces. The genius loci of these places is so interesting that just visiting them is an attractive experience. With appropriate technical modifications, it is possible to obtain an extremely attractive zone without high financial costs, which with its multifunctional possibilities will offer unusual experiences to the citizens of Brno and visitors to the city and will contribute greatly to the attractiveness of the Moravian metropolis.
