Techniques for managing delivery of water or other fluids have been disclosed. A central server provides real-time data and cost analysis to a client. In addition, fluid delivery techniques provide alerts or automatic schedule suspensions to reduce risk of loss. The techniques reduce or eliminate the impact of air or gas captured with water or other fluid of a fluid delivery system. The techniques allow a preexisting fluid delivery system to be retrofitted to communicate with a central system and one or more sensors of a fluid delivery system.
