ESA stands for Extended Service Agreement. Years ago, the District’s permanent water main system was not nearly as widespread through the District as it is today. As a convenience to certain property owners, the District allowed them to enter into Extended Service Agreements with the District, whereby they would be allowed to connect to a permanent water main some distance from their property—sometimes hundreds and in some cases, thousands of feet. The Extended Service Agreement is recorded against the title of the property, and runs with the property. Extended Service Agreements provide temporary water service until permanent service is available. When permanent service becomes available, the District terminates ESAs.
