Securing safe water distribution

Water consumption doubles in the summer
From the viewpoint of the Alavus water utility, the growth of the Kyläkauppa area in Tuuri has meant repeated measuring reviews on their water supply network. The water comes from two intake facilities, which are located about 10 and 15 kilometres from the village. If one line would fail, the other line could supply enough water – provided, that they were lucky enough. If such failure took place in the middle of the summer, a shortage of water would be a very likely scenario.
“Summer brings big crowds to the area, and the water consumption can be as high as 300 cubic metres per day. On the other hand, 130 cubic metres per day is more than enough in winter”, says Plant Manager Timo Seppä from the Alavus water utility.
“The Tuuri area has grown rapidly over the last ten years and continues to grow. We decided to install two 100-cubic-metre low water tanks on the area to balance consumption peaks and help in preparing for potential failures.”
Ready from the factory
Before making the decision to purchase the low water tanks, the water utility studied other options. These included, for example, increasing the size of the supply lines, but soon it was clear that storing the water is the way to go. Seppä had cost estimates calculated for both concrete and plastic tanks.
“It turned out that plastic is more cost-effective than concrete. Following a competitive tendering, Uponor won the contract, and they built the tanks and a pressure boosting station ready for installation at their factory.”
Both the tanks and the pressure boosting station were made from Weholite polyethylene pipe with an inner diameter of 2.4 metres. The length of each tank is 23.4 metres.
Straight into the trench
Uponor delivered the products to the site in Tuuri in September 2020. The Alavus water utility had commissioned the necessary excavation work and the construction of foundations, on which the tanks and the pressure boosting station were lifted and anchored by Uponor’s installation team. After the anchoring was completed, the water utility connected the tanks to the pressure boosting station and water supply network and filled the trench. Now the only things that are visible above ground are three manhole covers and two control cabinets for the electrical and automation systems.
“Installation was quick and smooth. The inlet and outlet fittings were exactly where they supposed to be, so it was easy for us to fit the pipes and valves between them.”
During the winter, the water utility’s own team continued to install the electrical and automation systems, and a decision was made to postpone commissioning so that it will take place closer to the summer, the high season of Tuuri. By that time, the installation of the remote monitoring of the tanks and the pressure boosting station will also be completed.

Szybka akcja była bardzo ważna, gdy poważnemu uszkodzeniu uległ kolektor ściekowy w Warszawie, powodując masowy wyciek nieczystości do Wisły. Załoga Uponor Infra pracowała 24 godziny na dobę, aby powstrzymać zanieczyszczenie rzeki. Tymczasowy rurociąg został wyprodukowany, dostarczony i połączony w ciągu zaledwie ośmiu dni.

City of Lahti is building new neighborhood called Ranta-Kartano. While they were constructing basic infrastucture the city saw the possibilty to reserve some ground space for storm water management. Now there is a test running for different kind of storm water management. Uponor is involved with new type of storm water filter.
