The City of Wyoming operates the Donald K. Shine Water Treatment Plant in Holland, a vital facility providing water to over 235,000 residents across Ottawa and Kent Counties. Established in the 1960s with an initial capacity of 32 million gallons per day (mgd), the plant has grown to accommodate regional demands and in 2024 has a treatment capacity of 120 mgd and an average daily discharge of 40 mgd. The plant services a wide range of communities, including Zeeland, Park, Olive, Blendon, Holland, Georgetown, Jamestown, Gaines, and Byron Townships, as well as the cities of Wyoming, Hudsonville, Grandville, and parts of Kentwood. Water is conveyed through two large diameter transmission mains, with a third transmission main planned for the future.
In July 2020, amid peak water demand season, the facility faced a significant challenge when one of the two transmission mains failed near the plant, effectively removing half of the City’s transmission capacity. The failure required immediate emergency repair during which interconnections to adjacent water suppliers were utilized and a sprinkling ban was implemented to reduce water demand.
The emergency repair jumpstarted a subsequent project to replace and enhance the City’s existing yard piping to address underlying concerns identified while investigating potential causes for the pipe failure. The expedited yard piping project was initiated in the Fall of 2020 with a target completion date of Spring 2022.
To meet this accelerated schedule, Prein&Newhof partnered with international engineering firm, Black&Veatch, to provide the City of Wyoming a valuable engineering team with local expertise and responsiveness partnered with the knowledge and resources of a large firm.
The project included the installation of a new 54-inch steel pipe within the plant’s yard and the addition of six metal-seated AWWA ball valves—five 54-inch and one 42-inch. These valves were strategically placed to allow for the isolation of different segments of the transmission main, facilitating easier maintenance and repairs. Additionally, a section of the existing 54-inch transmission main on New Holland Street was replaced to ensure proper thrust restraint and to reinforce the system. Lastly, the yard piping project included a connection point for the third planned transmission main.
