The customer shall agree to accept the elevation and location of all sewers as laid by the utility and will, where necessary, install and operate on his/her own premises and at his/her own expense, all necessary sewage lifting equipment or backup protective devices. Customers having drain or fixture outlets into the house connections that are at an elevation that is lower than the top of the nearest downstream sanitary sewer manhole shall protect their premises from possible backup of sewage by the installation of backflow or other devices to prevent sewage backing up and flowing out of such outlets. Such customers agree to accept responsibility for any damages caused by a sewage backup where the customer has failed to install devices to prevent such a sewage backing up and agrees to hold the City of El Paso, the utility and/or the Public Service Board harmless for any damage caused by such a sewage backup.
In areas where the vacuum sewer lines are installed, service valve boxes are required for service. As a condition of service, the service boxes may be located on the customer’s premises in an area determined by the utility to be accessible at all times for inspection, testing and maintenance. One service box may serve two or more properties. The service box may be set on the property line between adjoining served properties or on any of the served properties. The customer shall maintain the surrounding property in a manger that protects the service box from damage and assures that it is clearly visible. The customer shall immediately report any defect or damage he/she observes in the service box to the Utility.
