What are Assets?

3

An asset is a resource with economic value and the expectation that it will provide a future benefit. Facilities

  • Storage tank
  • Well pump stations
  • Water treatment plant

What is Asset Management?

4

Asset Management is a systematic process of

  • perating, maintaining, upgrading and disposing
  • f assets cost-effectively while maintaining a level
  • f service that is acceptable to the customers.

  • 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

Level of Service

A Level of Service Agreement (LOS) defines how the utility owners, managers, operators and customers want the system to perform

  • ver the long term.

The District chose to create a LOS that covers both vertical and distribution system assets “Report Card” for the system

Level of Service

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

  • 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

  • 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

Next Steps: Asset Management Maintenance Plan

19

Revise asset information as inspections, rehabilitation and repair projects are completed. Continue collection of missing assets and asset characteristics. Add asset information assessment information to GIS and CUPSS.

1 2 3

Revise CIP and FIP annually as part of the budget development process. Provide training to staff members who will be maintaining data sets and coordinating with GIS and

  • CUPSS. (Use RCAP)
