Review of System Capacity Determination
New Jersey American Water Approach
GOAL: An abundant water supply of superior
quality, available in adequate volume and pressure,
whenever and wherever is needed.
2
Asset Planning Functions
 Identifies and shepherds comprehensive planning studies
which identify needed projects for sustainability of current
and future system demands
 Performs system analysis to verify capacities and
availability
 Records and maintains buried assets geographic locations
and attributes
3
Verification of System Capacity
• System Capacity Analysis/Evaluation of:
 Source of Supply
 Production / Treatment
 Supply Conveyance / Delivery
 (Pressure Regulation, Distribution, Transmission)
 Storage
 (Equalization, Fire Flow, Emergency Supply)
 Other System Deficiencies

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
6
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. 7:1012.6(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.

*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
10
Firm Capacity & Water Allocation Analysis
 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
11
Firm Capacity & Water Allocation Analysis
 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

Water Allocation Analysis
Current Water Allocation Permit Limits
Monthly: 170.5 MGM
Annual: 1,443.0 MGY
• 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
