Presentation Overview What are Assets? What is Asset Management? Existing Infrastructure Level of Service (LOS) Analysis Risk Prioritization Recommendations Next Steps 2

What are Assets? An asset is a resource with economic value and the expectation that it will provide a future benefit. Distribution Facilities • Valves • Storage tank • Water Main • Well pump stations • Hydrants • Water treatment plant • Services 3

What is Asset Management? “ Asset Management is a systematic process of operating, maintaining, upgrading and disposing of assets cost-effectively while maintaining a level of service that is acceptable to the customers. 4

What is Asset Management? This is a continuous Existing process that should be Infrastructure revisited annually. Capital Level of Improvement Service Plan This is a continuous process that should be revisited annually. Risk Risk Analysis Prioritization 5

Existing Infrastructure - Summary Asset Type Count Bedrock Wells 8, (6 active) Source Water Facilities 4 Storage Tanks 1 Distribution Main ~13 miles Gate Valves 85 Hydrants 11 Zone Meters 4 Service Connections 538 Service Meters 0 >$15M in assets! 6

Asset Inventory & Condition Assessment • District uses online tools like Google drive for record information storage and data collection • Asset Inventory and condition assessment information on vertical assets included in ELVD CUPSS for asset inventory • Distribution system assets and attributes included in GIS database 7

Level of Service A Level of Service Agreement (LOS) defines how the utility owners, managers, operators and customers want the system to perform over the long term. The District chose to create a LOS that covers both vertical and distribution system assets “Report Card” for the system 8

Level of Service Frequency of Goal Target Level Measurement All federal and state water quality regulations will be <MCL Annually met Unaccounted-for-Water less than 15% <15% Annually The system will maintain a minimum pressure of 35 psi and a minimum operating pressure of 20 psi >35 psi Monthly under all flows All customer complaints will be investigated within 1 1 day Monthly business days of reporting the complaint. Breaks will be repaired within 24 hours of being > 95% Monthly reported 95% of the time. Contact the Board of Commissioners at least 48 hours prior to water main shutdown in planned situations < 48 hrs Monthly and ASAP in emergency situations. No adverse event will cause the customers to be 0 events Monthly without water. 9

Analysis – Interconnections • Interconnection options with Hillsborough and Henniker (6 options considered) • Each includes a booster pump station and meter building • Water main extension lengths vary from ~10,000 ft to 15,000 ft • 3 options include crossing Rt 202A • Conceptual project costs vary from $3.9M to $4.8M 10

Analysis – Source Water • Supplement current supply • Installation of pressure transducer and increased monitoring at existing wells • Bedrock and sand and gravel deposits • Multiple sand and gravel sites identified for further investigation 11

Analysis – Water Main & Storage • Water main replacements o Breaks, age • Storage tank o Cleaning and inspections • New zone meters o Hemlock o Turtle crossing bridge • Customer meters 12

Analysis – Metering • Temporary waiver from service meter installation • Zone metering o 5 meters o 2 proposed o ~90% of system covered after installation of add’l meters • Service meters recommended 13

Priority Recommendations Improvement Description Purpose of Improvement Length (ft) Total Project Cost Old Lantern Road Water Main Replacement Breaks, Age, Material 1,200 $252,000 Deerpoint Dr Water Main Replacement Breaks, Age, Material 1,800 $378,000 Well Transducer Installation Inadequate water source production - $35,000 Sand & Gravel Well Exploration Inadequate water source production - $40,000 Patten Hill Tank Recommendations NHDES Recommendation - $12,000 Patten Hill Control Building Recommendations NHDES Recommendation - $45,000 Meeting House WTP Recommendations NHDES Recommendation - $88,000 New gravel-packed well Inadequate Water Source Production/Water Quality - $280,000 Water Storage Tank Inspection Maintenance - $5,000 Zone Meters WCP Compliance - $20,000 SUBTOTAL $1,155,000 16

Secondary Recommendations If new source water development is successful, interconnection may not be necessary or can be delayed. Project costs should be transitioned to water main replacement or service meter installation.

Next Steps: Asset Management Maintenance Plan 1 4 Continue collection of missing assets Provide training to staff members and asset characteristics. who will be maintaining data sets and coordinating with GIS and CUPSS. (Use RCAP) 2 5 Revise asset information as Revise CIP and FIP annually as inspections, rehabilitation and repair part of the budget development projects are completed. process. 3 Add asset information assessment information to GIS and CUPSS. 19

Next Steps This is a continuous Existing process that should be Infrastructure revisited annually. Capital Level of Improvement Service Plan This is a continuous process that should be revisited annually. Reapply for DW Grant Program in December? Risk Risk Analysis Prioritization 20
