The Rotorua City Hot Water System

Abstract

The hot water sone City is fed, at least in part, from the geothermal system the south of the city. There is a growing publio view that use of the water energy from the hot water system could be in conflict with the need to maintain pressures and flows in the Whakarewarewa the surfaoe activity, so important a tourist asset, at its peak. This study of the Rotorua hot water system is a two study. In the first place we must the system, draw up a possible physiao-hydrological of system. Then we must the behaviour of this conceptual model to see just how much mass and energy may be extracted without adversely affecting the Whakarewarewa system and determine the of different withdrawal rates and withdrawal locations. Due to our current lack of knowledge of this system, of the second part of this study ban only'be conjectural. In this paper we thus purely on conceptualisation of the to make some conjecture.
