  1. Safe Drinking Water Permit and Capacity RequirementsDeveloper Services SummitNovember 16, 2010 Engineering - Asset PlanningVince Monaco

  2. Objectives • Explain Asset Planning Functions • Review SDW Permitting Requirements • 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.

  3. 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

  4. 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

  5. Established in the SDWA Rules at NJAC 7:10-11.5 Application Endorsements Engineering Report Plans and Specifications Fees SDW Permit Application Process: Standard Application Simplified Master Permit Application SDW Application Types

  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. 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.

  8. Residential Site Improvement Standards

  9. Non-Residential Demand

  10. Non-Residential Demand (continued) TABLE 1- AVERAGE DAILY WATER DEMAND Type of Establishment Gallons per Person 17. Swimming pool or bathhouse ………………………………………………. 10 18. Club house* a. For each resident member ………………………………. 60 b. For each nonresident member ………………………………. 25 19. Nursing home 150 20. Campground a. Without individual sewer hook-up ………………………………. 75 per site b. With individual sewer hook-up ………………………………. 100 per site c. With laundry facility and individual sewer hook-up ………………. 150 per site 21. Store, office building ………………………………………………. 0.125 gal/sq. ft 22. 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. 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

  12. 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

  15. Calculating Projected System Water Demand

  16. Water Allocation Analysis Current Water Allocation Permit Limits Monthly:170.5 MGM Annual: 1,443.0MGY • Formula for Calculating Peak MonthlyDemand: • 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 AnnualDemand: • Peak Annual + 365 (outstanding avg. + estimated avg. project demand) = • 1,330.8 MGY(2009) + 365(0.0668 + 0.015) = 1,360.66MGY

  17. Our Challenges . . .

  18. Number and System Sizes • Five large regional water systems • 30 Additional water systems • 17 Counties • 187 Municipalities • 323 MGD production • All regional systems have supply capacity surpluses • Five relatively small systems have supply capacity challenges • Several remedial projects are being planned

  19. Surplus Deficit Systems with Supply Surplus & Supply Deficit

  20. Select County & search Select this option

  21. Check these critical items

  22. Master Permits • Raritan • Union, Somerset, Middlesex, Mercer, Morris and Hunterdon County • Coastal North • Middlesex, Monmouth, and Ocean County • Coastal South • Atlantic County • Delaware River Regional • Burlington, Camden, and Gloucester County
