6. 6 System Capacity Determination  Each applicant for a permit to construct or modify a public community water system must demonstrate that a proposed water system improvement, extension or connection will not exceed the firm capacity of the water system or the water diversion limits contained in an applicable water allocation permit.  Source and Treatment Capacity Evaluation -Firm Capacity Determination -Monthly Demand -Yearly Demand  Reliable Capacity

7. 7 Definitions: “Firm Capacity” means adequate pumping equipment and/or treatment capacity (excluding coagulation, flocculation, and sedimentation) to meet peak daily demand, as defined below, when the largest pumping station or treatment unit is out of service. "Peak daily demand" means:  For modification to or extension of an existing water system, the average daily demand as recorded in the peak month of the prior five years, plus an estimation of the anticipated peak daily water demand calculated as follows:  Residential – Average daily demand according to DCA’s Residential Site Improvement Standards (RSIS), N.J.A.C. 5:21-5.2(d);  Non-Residential – Average daily demand according to N.J.A.C. 7:10- 12.6(b), Table 1;  The sum of the above multiplied by a peaking factor of three (3)  For a proposed new water system, an estimation of the anticipated peak daily water demand calculated for residential and non-residential development, per the above.

Self-service laundry ……………………………………………….50 gal/wash *Includes kitchen demand at 10 gallons per person per day. If laundry demand is anticipated, the estimated water demand shall be increased by 50 percent. **Demand projections shall be calculated by multiplying the certified seating capacity of the establishment by the applicable water usage in gallons per person under 9a, b or c above, and by a factor of 1, 2, or 3 reflecting the hours of operation, as follows: one to six hours (1), seven to 12 hours (2), or more than 12 hours (3). ***When the establishment will serve more than one use, the multiple use shall be considered in determining water demand

11. 11  The Firm Capacity and Water Allocation Analysis consists of two (2) components:  1) Firm Capacity: The proposed water system has adequate firm capacity to meet all of the following:  Existing peak daily demand  Anticipated peak daily demand from both of the following:  Previously approved but not yet constructed DEP-permitted water main extensions or connections; and  Non DEP-permit water main extensions committed to, but not yet completed by, the water supplier  Anticipated peak daily demand from the subject application Firm Capacity & Water Allocation Analysis

12. 12  2) Water Allocation: The applicant possesses a valid water allocation permit with sufficient monthly and annual diversion limits and/or bulk purchase agreements to meet existing and estimated demand, as follows:  Monthly – Average daily demand calculated for residential and non-residential development as above, multiplied by a peaking factor of 1.5, and then multiplied by 31 (days/month)  Annual – Average daily demand calculated for residential and non-residential development as above, multiplied by 365 (days/year) The estimated peak monthly and annual demand shall be added to the respective, existing demand figures and then compared to the applicable water allocation permit limits Firm Capacity & Water Allocation Analysis

16. 16 Formula for Calculating Peak Monthly Demand:  Peak Monthly + [1.5(outstanding avg. + estimated avg. project demand) x 31] =  155 MGM (July/2010) + [1.5(0.0668 + 0.015) x 31] = 158.804 MGM Formula for Calculating Annual Demand:  Peak Annual + 365 (outstanding avg. + estimated avg. project demand) =  1,330.8 MGY(2009) + 365(0.0668 + 0.015) = 1,360.66 MGY Current Water Allocation Permit Limits Monthly: 170.5 MGM Annual: 1,443.0 MGY Water Allocation Analysis
