The Water Main Blowout on Lake Washington
A faulty metallic plug failed under pressure, exposing the vulnerability of Seattle's early water infrastructure.
The story, cleaned up
A cleaned-up reading of the newspaper page: spelling and layout repaired, one story lifted off a crowded page. It follows the original closely but it is not a transcription. The original page is below; read it if a detail matters.
The cause of the burst main on Monday between the Lake Washington pumping station and the reservoir was not due to a break in the pipe, but to the blowing out of a plug. At several intervals the pipe is joined by a section formed like a Maltese cross. To two of the branches are attached the main now in use, leaving the other arms ready when the time shall come to put in cross mains. These are at present stopped by metallic plugs, held in place by fused lead. One of these, through some flaws in the metal, had gradually worked itself loose and was finally forced out by the pressure. A new plug was put in and the damage was repaired. 'I would like the council,' said Superintendent Calligan, 'to authorize a valve or gate near the reservoir and another near the pumping station. It is unsafe to be without it. If they will not go to that expense there should be a pipe from the present point where the water enters the reservoir to a height equal to that of the usual level of the water. Then if a break occurs the water cannot flow back. We have such a safety for the Dow and Worthington, but not for the Holly pump.'
“It is unsafe to be without it. If they will not go to that expense there should be a pipe... Then if a break occurs the water cannot flow back.”
Early Seattle infrastructure was plagued by rapid, sometimes shoddy expansion; the concern over the 'Holly pump' safety features highlights the constant fear of water loss in a growing wooden city. Today, Seattle's water system remains a top-tier civic obsession, though the risks have shifted from simple pipe plugs to seismic resilience and regional drought.
