A History of the Millbrook Waterworks

Early years

Before 1887, Millbrook drew its water the way most small towns did: from private wells, a handful of shared pumps on the main street, and, for those who could afford it, a cistern fed by roof runoff. This worked poorly. The town's own health records from the 1870s show repeated outbreaks of what was then called "summer fever" — almost certainly waterborne illness, though the germ theory behind it was still new enough that most residents blamed the weather instead. It took a particularly bad outbreak in the summer of 1883, which killed eleven people in a town of under two thousand, to force the question of a proper water supply onto the town council's agenda for good.

The council spent nearly four years arguing about it. Not about whether a waterworks was needed — by 1884 almost nobody disputed that — but about where to draw from, who would pay for it, and whether the town should build and run it itself or contract the work out to a private company, as several neighbouring towns had done. The private-company faction lost, narrowly, after the council toured a waterworks in a nearby town that had been run privately for six years and found its rates had tripled with no corresponding improvement in service. Millbrook decided to build and own its own works.

Construction and the first reservoir

Construction began in the spring of 1886, drawing from Millbrook Creek roughly two miles upstream of the town centre, where the water was judged cleanest. The site chosen was a natural basin in the hills that needed only a modest earthen dam to become a workable reservoir — this became the original Millbrook Reservoir, still in use today though heavily rebuilt since. The engineer in charge, a Scottish immigrant named Alasdair Reid who had worked on waterworks in Glasgow before coming to North America, insisted on a slow sand filtration system rather than the cheaper alternative of no filtration at all, which was still common practice for a town this size at the time. This decision, more than any other single one, is usually credited with why Millbrook's water-related illness rates dropped so sharply once the works opened, well before most of its neighbours saw similar improvements.

The works opened in October 1887, a year and a half after construction began, at a final cost of just under sixty thousand dollars — considerably over the original estimate, mostly due to unexpected rock excavation for the pipeline route. The opening was marked with a public ceremony at which the mayor reportedly drank a glass of water drawn directly from the new mains, a piece of theatre that was apparently repeated, with much less enthusiasm, at every subsequent mayoral inauguration for the next thirty years.

Expansion through the early twentieth century

The original works served the town well for about two decades, but Millbrook's population nearly doubled between 1890 and 1910 as a shoe-manufacturing plant opened on the eastern edge of town and drew workers from surrounding rural areas. By 1908 the reservoir was running close to capacity in dry summers, and the council authorized a second reservoir, built further upstream and connected by a new pipeline, completed in 1912. This is the reservoir now known locally as the "new" reservoir, despite being well over a century old itself — a naming quirk that has confused more than one newcomer looking at an old map.

The shoe plant itself became the works' single largest customer for several decades, at one point accounting for nearly a fifth of total water usage in town. When the plant closed in 1968, following the broader decline of domestic shoe manufacturing across the region, the waterworks lost enough revenue that rates rose noticeably for several years afterward — one of the few times in the works' history that a single customer's departure showed up directly in ordinary residents' bills.

Modernization

The slow sand filters that Reid insisted on in 1887 remained in continuous use, with periodic resurfacing, until 1974, when the works were modernized with a mechanical filtration and chlorination system more typical of the era. Two of the original filter beds were preserved rather than demolished, at the request of the town's newly formed historical society, and can still be seen — no longer operational, but maintained as an exhibit — at what is now the Millbrook Waterworks Museum, itself opened in 1981 in the original pump house.

Further upgrades followed roughly every twenty years: a new treatment plant in 1996 that finally retired the last of the 1912-era pipework, a supervisory control system installed in 2009 that allowed the works to be monitored remotely for the first time rather than requiring an operator on site around the clock, and most recently a lead service line replacement program begun in 2019 and still ongoing, targeting the roughly six hundred properties in the town's oldest neighbourhoods still connected by pipe materials that predate any of the modern safety standards.

The works today

The Millbrook Waterworks now serves just over nine thousand customers across the town and two adjoining unincorporated areas that have contracted for service over the years. It remains municipally owned, as the 1884 council decided it should be, and is one of relatively few waterworks of its size in the region never to have been sold to a private operator, a fact the utility's own annual report has mentioned, with evident pride, in some form for at least the last twenty consecutive years.
