WATER CAPACITY FEESBeyond updating the fee, Willdan is recommending the District update the existing fee structure. Currently, theDistrict’s capacity fee is calculated by ERU – where each new connection equivalents units have to be manuallycalculated based on a variety of factors. The proposed water connection fees are based on the size of the installedwater meter, as recommended by the American Water Works Association (AWWA). A capacity ratio, based on themeters flow rating (in gallons per minute), is used to determine a capacity ratio from a standard 5/8 inch meterinto a proportionate fee for larger meter sizes. The capacity ratios are consistent with industry standards and arean accurate reflection of the possible demand of different meter sizes.For the smallest meter size, 5/8 inch water meter, the fee is derived by multiplying the gallons per day perresidential connection (figure 2-5) by the total capital cost per gallon of capacity (figure 2-5). The next step in thefee calculation is to add the average cost per water customer for joint costs. For example, 310 peak gallons perresidential connection (from Figure 2-5) multiplied by $6.99 (cost per gallon of capacity - Figure 2-5) equals $2,168Adding $189.63 (capital cost per connection) yields a capacity fee of $2,358 for a 5/8 inch meter. For larger metersizes, include the capacity ratio in the formation fee (before adding the capital cost per connection)FIGURE 2-6: WATER CAPACITY FEESComponent Unit Cost $1.98 $5.02 $189.63Component Mutliplier 310 310 1Water MeterSize GPM Capacity Ratio Storage Distribution5/8" 20 1.0 $ 613 1,555Joint Costs(per account)Total$ $ 189.63 $ 2,3583/4" 30 1.5 919 2,333 189.63 3,4411" 50 2.5 1,532 3,888 189.63 5,6091 1/2" 100 5.0 3,064 7,776 189.63 11,0292" 160 8.0 4,902 12,441 189.63 17,5333" 300 15.0 9,191 23,328 189.63 32,7084" 500 25.0 15,318 38,880 189.63 54,3876" 1000 50.0 30,636 77,759 189.63 108,5858" 1600 80.0 49,017 124,414 189.63 173,62110" 2300 115.0 70,463 178,846 189.63 249,498Please note, due to recent changes in building code regulations, new single-family homes are to be sized with a 1”meter because of fire protection systems, rather than the typical 5/8” meter. It is recommended that all newsingle-family residential units, with meter sizes 5/8” up to 1”, be charged the 5/8” meter rate to reflect their typicaldemand on the system.MCSD | Capacity Fee Study - Final 9
