<br />The total future project costs allocated to growth from Table 8 are used to determine the unit costs of
<br />capacity reflected in Table 3. Table 3, like Table 2, consolidates the growth costs by parameter and
<br />summarizes the cost per unit of capacity (derived by dividing the total cost per parameter by the
<br />projected growth units).
<br />
<br />Tables 7 and 8 summarize the results of individual project cost allocation. To illustrate the application
<br />of the methodological steps, as shown in Figure 3, to individual projects from the proposed 20-year
<br />project list, several examples are provided bellow.
<br />
<br />Project Allocation Example A: Collection System, Screw Pump Station Expansion
<br />Total cost of the project is $1.7 million. Basis of improvement fee for this project is:
<br />$650,000 or approximately 38% of the total project cost, derived as follows:
<br />
<br />Step 1: Allocation of project to facility components
<br /> · 1/2 to Collection System Pump Stations = 50% x $1,700,000 = $850,000
<br /> · 1/2 to Peak Flow Management -- 50% x $1,700,000 = $850,000
<br />Step 2: Allocation of facility components to capacity parameters
<br /> · Collection System Pump Stations: 1/4 average flow = 25% x $850,000 = $212,500; 3/4 peak flow
<br /> = 75% x $850,000 = $637,500
<br /> · Peak Flow Management facility component is allocated 100% to Peak Flow capacity parameter =
<br /> 100% x $850,000 = $850,000
<br /> Step 3: Allocation of project to project type
<br /> · 100% of project (both Collection System Pump Stations and Peak Flow Management) is Capacity
<br /> project type
<br /> Step 4: Allocation of project to user type
<br />
