About this file

Written by GovTribe AI ·

This file is a sample water quality and operational data report for the Yuma Desalting Plant (YDP) for fiscal year 2026, documenting potable water and service water treatment performance metrics. The report contains detailed daily operational data for June 10, 2026, including three main treatment train sections: Pilot System 1 (PS1) Pretreatment, PS1 Reverse Osmosis (RO) systems, and potable/service water quality parameters. Key operational metrics tracked include turbidity (measured in NTU), pH levels, free and total chlorine residuals, conductivity, flow rates, and pressure differentials across cartridge filters and RO membrane stages. The document specifies water quality compliance standards, such as maintaining turbidity under 0.30 NTU for 95% of monthly readings, minimum free chlorine residuals of 0.2 mg/L, and pH ranges appropriate for each treatment stage.

The report also includes calendar year 2025 summary data showing cumulative water diversions, production volumes, and consumptive use tracked in acre-feet across multiple water source feeds including the Colorado River, WQIC well, and MODE (Main Outlet Drain Extension). Daily product discharge records indicate YDP produced approximately 247,116 cubic meters (approximately 200 acre-feet) of product water distributed through service water systems, potable water systems, and discharge to the Colorado River, with documented operational events including temporary flow interruptions for maintenance, equipment cleaning, and system outages. The facility tracks water conservation metrics, cooling tower operations, irrigation usage, and maintains detailed records of chemical dosing rates for sodium bicarbonate, ferric sulfate, lime slurry, and antiscalant (VITEC 5100) to optimize treatment efficiency and water quality compliance.
