The springs at Deildartunga supply 180 L/s of water at

96oC and the wells at Baer can produce about 20 L/s in artesian

flow. Thus, the combined supply capacity is 200 L/s.

Currently, however, the system is using only 170 L/s at peak

load, which are taken from the Deildartunga hot springs. The

wells at Baer are only used if the supply from Deildartunga is

interrupted for some reason and flows cannot be maintained

by the storage tanks.

The collection system at the springs is very simple. An

arrangement of low walls guides the boiling water into the

collection pipes. These conduct the fluid to a nearby pumping

station that pumps the water up to a storage tank at the

highest point in the pipeline at Kroppsmuli a few km away.

The system also includes two storage tanks to maintain supplies

to Akranes and Borgarnes if breaks in the transmission

pipeline occur. The tank at Borgarnes has a capacity of 2,500

m3 and that at Akranes 2,000 m3. These give the

nmaanicnete c-rews several hours in which to repair breaks. Pumping

stations are at six different places in the system.

The distribution system is a single pipeline system, made

of buried steel pipes, pre-insulated by polyurethane. The total

pipe length of the distribution system is 107 km; thereof,

57 km in Akranes, 23 km in Borgarnes and 27 km in the rural

areas. The water supplied is used directly by the users in their

is disposed of through the local wastewater system.

radiator systems and as domestic hot water. The return water is
disposed of through the local wastewater system.
