Well Replacement and Rehabilitation to Restore Firm Capacity


  • Eileen Murphy PE - Hazen and Sawyer

The plight of aging infrastructure, an aging work force, and financial constraints have forced water utilities into a reactionary state foregoing scheduled maintenance and heading straight to capital construction and emergency repair. Using the East Orange System as a case study, the presentation will provide:

- An overview of the East Orange Water System; the struggle to meet firm capacity and where they are today. – Review of the fundamental steps of Well Replacement and Well Rehabilitation will be covered along with the construction schedule and maintenance of existing operations. – Review of the Drilling Methods, and Construction Issues encountered during well replacement. – Review of the types of equipment and rehabilitation methods used at East Orange and the level of success achieved. – Finally, a review of key monitoring parameters and recommended maintenance for groundwater systems will be covered to improve system reliability.
