The water supply covers most of the Kalajoki Valley and includes the cities of Kalajoki, Ylivieska, Nivala and Haapajärvi, as well as the municipalities of Sievi and Alavieska. Himanga's water intakes and trunk lines were transferred to the ownership of Vesikolmio Oy on 1 January 2015. In 2015, approximately 3.78 million m 3 of groundwater was sold . Water distribution facilities also supply Vesikolmio's domestic water outside the cooperatives, such as the Alaviirte Water Cooperative, Pyhäjoki, Merijärvi and Haapavesi. Groundwater is supplied to about 21,000 water connections with about 54,000 water users. The connection rate to the public water supply network is 99%. HOUSEHOLD WATER SUPPLY Approximately EUR 3.8 million is purchased annually for domestic water in the Kalajoki Valley. m 3 of good quality groundwater from Sievi, Kalajoki and Haapajärvi groundwater bodies. The pumping volumes are distributed as follows: Sievi 52%, Kalajoki 30% and Haapajärvi 18%. Water supply is dimensioned so that water demand can be met even during peak consumption times. Back-up power plants are permanently installed in water intakes and intermediate pumping stations to ensure a continuous supply of water. The contingency plan has been made to ensure security of water supply even in exceptional situations. Backup power machines ensure a continuous supply of water. HOUSEHOLD WATER TREATMENT AND WATER RESEARCH The groundwater supplied by the water triangle fully meets the quality requirements and quality monitoring is carried out in accordance with the control research program. The groundwater of the water triangle would be suitable for use as such, but a little lime is added to the water to prevent corrosion. Water treatment takes place at all water intakes with limestone. Water pumped from the water intakes into the network is disinfected with a UV sterilizer to ensure quality. Veden laadun tarkkailupalvelua hoitaa Eurofins Scientific Finland Oy:n laboratorio- ja ympäristöpalvelut Kokkolasta. Vesikolmion toimittama pohjavesi täyttää kaikilta osin laatuvaatimukset ja laadun tarkkailu tehdään valvontatutkimusohjelman mukaisesti. Verkostoon pumpattava vesi johdetaan UV-sterilisaattorin läpi. KAUKO-OHJAUS JA HÄLYTYSJÄRJESTELMÄ Vesikolmion ja asiakaslaitosten toimintaa valvotaan ja ohjataan reaaliaikaisella kaukokäyttöjärjestelmällä. Osakaslaitokset ovat yhteydessä valvomon päätietokoneeseen sivuvalvomo-ohjelmalla. Sivuvalvomoista voidaan seurata tapahtumia, mutta ohjaustoimenpiteet tehdään päävalvomossa tai päivystäjäpäätteellä. Keskusvalvomon normaalin työajan käyttöpalvelu ostetaan Ylivieskan Vesiosuuskunnalta ja muuna aikana Vesikolmion päivystäjät hoitavat valvomon käyttö- ja hälytystyöt. Operations are monitored and controlled using a remote control system. Vesikolmio Oy | Vesitie 7, 85500 Nivala | Tel. (08) 440 266 Fax (08) 440 252 Emergency telephone 2 4 h / day 0 4 4 0 8 9 0 2 1 9
