Building the Capacity of Drinking Water Systems

Water System Partnerships Case Studies

Drinking water systems across the country face unique challenges to provide safe drinking water and operate with often limited resources. Partnerships are a tool to help address those challenges, with options ranging from informal arrangements, such as sharing equipment, to transferring ownership of a system through consolidation. The proximity of systems to potential partners can provide many opportunities for systems to form cooperative agreements, share services, or join together under common management.  Additionally, systems with common needs that are geographically separated can enter into partnerships where remote operations, such as billing, or customer services, are shared.

The case studies found on this page help highlight the many potential opportunities for partnerships. 

Types of Partnerships

 Informal Cooperation: Working with other systems, but without contractual obligation. Examples include sharing equipment, sharing bulk supply purchase, and mutual aid arrangements.

 Contractual Assistance: ​Requires contract, but contract is under system's control. Examples include operation and maintenance (O&M), engineering, and purchasing water.

 Joint Power Agency:​ Creation of a new entity by several systems that continue to exist as independent entities. Examples include     shared management and shared operators.

Ownership Transfer: ​Takeover by existing or newly created entity. Examples include acquisition with physical interconnection and/or satellite management, as well as the creation of a new public entity.
