The source of drinking water for the city of Narva is the Narva River at its upper course. Water comes to purification facilities from a collecting facility located at a 26-kilometre distance from the city.
The building of the new water collecting facility was completed on the Mustajõe River in 1997. A new 26 kilometres long water main was launched in 1998.

The intake is a two-part reinforced concrete construction planted in the riverbed, 30 metres from the bank. The inner cavities are filled with gravel and closed with a big-cell net to prevent fish, water-plants, etc., from getting into the system. From the intake, water flows through two Ø 1200 mm pipelines to collecting chambers.
The amount and pressure of water are registered by the Dispatcher program installed on the computer in the WPP Centre. The current and total flow of water in the pressure collectors is taken from the readings of meters installed on pipelines in the switching unit. The work of the Mustajõe water collecting facility is controlled remotely from the WPP Centre.
There are alarms at the collecting site. If they start working, the signal is forwarded to the computer in the Centre.
