Abstract
The Philip geothermal district heating project, which uses the waste water from the Haakon School, has now been in operation for 15 years. The origins of this project is discussed in the article by Childs, et al., (1983), presented in an abbreviated form in this issue of the Bulletin. This project was one of the 23 cost shared by USDOE starting in 1978, of which 15 became operational. The city district heating system was added on to the original USDOE cost shared project for the Haakon School (named after King Haakon V of Norway). The 4266-ft. (1,300-m) deep artesian well can provide up to 300 gpm (19 L/s). It has a shut-in pressure of 52 psi (3.6 bars) and will flow naturally at 15 gpm (0.9 L/s) (Fig 1). Today, there are eight buildings in downtown Philip using the geothermal heat as shown in Figure 2. The waste water from Haakon School is delivered downhill in a single six-inch (15-cm) preinsulated FRP pipeline to town at 120 to 145oF (49 to 63o C), depending upon the outside temperature and the amount of heat extracted at the school. The pipeline Figure 1. Haakon School well with maintenance person William DeLayne. Figure 2. Philip district heat system schematic.
