Ephrata Public Utilities District Service Center

Grant County Public Utility District (Grant PUD) is developing a new $188.6 million service center in Ephrata, Washington, to support its growing utility operations. The 34-acre campus will include maintenance and fabrication shops, warehouse facilities, covered vehicle storage and operational support spaces.

Designed to accommodate more than 30 years of growth, the new facility will replace an aging downtown service center that no longer meets the utility’s operational needs.

The Challenge

The existing service center, built in the mid-1970s, had become overcrowded and inefficient, with limited room for expansion.

The new facility requires durable concrete floors capable of withstanding demanding operational conditions, including heavy vehicle traffic, rolling loads, equipment movement and daily wear. Long-term durability is essential to minimizing maintenance interruptions and supporting reliable utility operations.

The Solution

Hard-Cem^® Integral Hardening Admixture is being incorporated into the new service center’s concrete slabs to improve abrasion and erosion resistance. Unlike surface-applied hardeners, Hard-Cem is added directly to the concrete mix, providing wear resistance throughout the slab without relying on a separate surface treatment.

This approach supports Grant PUD’s commitment to building a durable, resilient facility designed for decades of service. By improving concrete wear resistance, Hard-Cem is intended to help preserve floor conditions, reduce the potential for premature repairs and support long-term operational efficiency.

With construction underway and initial occupancy anticipated in early 2028, the project demonstrates how integral concrete durability solutions can support long-term infrastructure investments.
