1. Introduction

1.1. Summary

The City of Waxahachie, Texas (hereinafter referred to as the "City" or "Owner") is soliciting proposals from qualified vendors to provide a comprehensive, turnkey chlorine dioxide generation program for the Howard Road Water Treatment Plant and the Robert W. Sokoll

Water Treatment Plant. This Request for Proposals (RFP) seeks a full-service solution that includes equipment provision, installation, chemical supply, routine maintenance, regulatory testing, and ongoing technical support for a two-chemical process.

1.2. Background

The City of Waxahachie operates two major water treatment facilities that serve as critical infrastructure for delivering safe, reliable drinking water to residents and businesses across the region. Chlorine dioxide plays a vital role in the City's disinfection strategy, offering powerful microbial control while minimizing disinfection by-products such as trihalomethanes (THMs) and haloacetic acids (HAAs).

The current chlorine dioxide generation equipment at both facilities has reached the end of its expected service life and requires replacement with modern, high-efficiency generation systems. The City seeks a vendor partner who can deliver a seamless transition to new equipment while maintaining uninterrupted disinfection operations.

Existing generation systems are at or beyond their useful life. The City seeks a modern, reliable, and performance-guaranteed solution that:

• Maintains uninterrupted disinfection

• Improves efficiency and chemical utilization

• Ensures regulatory compliance

• Reduces operational and maintenance burden on City staff
