WINNIPEG — As spring runoff begins, Manitoba Hydro is reminding homeowners to be mindful of where they direct water from their sump pumps — especially if they have a padmount transformer (those green electrical boxes) in their yard.
The utility says crews have already spotted several transformers surrounded by standing water this season. While the equipment is designed to withstand moisture and sits elevated on concrete or fibreglass pads, prolonged exposure to pooling water can corrode internal components, potentially leading to costly repairs and power outages.
“If your sump hose is going all the time, it’s best to direct the water elsewhere before the transformer turns into a green metal island,” Manitoba Hydro advises.
Homeowners are also encouraged to consider landscaping solutions to keep meltwater flowing away from these boxes. Anyone planning to dig should contact the utility first to avoid damaging underground cables.
Padmount transformers are commonly used in neighbourhoods with underground power lines, reducing electricity voltage before it reaches homes.
