Here’s why water service interruptions happen even if dams overflow

When a sequence of typhoons, capped off by Storm Ulysses, ravaged the nation and unleashed heavy rainfall sufficient to overflow dams in Luzon, loads of Filipinos had been perplexed that water provide was instantly interrupted.

Whereas there may be actually an overflowing quantity of uncooked water, this water is much from potable and due to this fact can’t be equipped to customers instantaneously. Right here’s why:


To simply visualize what a dam may appear like if its partitions had been see-through – similar to an aquarium – think about a tall glass of hazy water with filth on the backside. The water is hazy due to minerals, soil, clay, and so on., that stream into the dam with the water coming from mountain tops. The filth on the backside of the glass we’re visualizing are known as sediments—all of the aforementioned minerals, filth, and contaminants that ultimately settled down.

When heavy rain strikes the dam water constantly, it’s as if you happen to had been mixing the glass of water and filth with a spoon, ultimately turning the water into one that will appear like a chocolate drink with nearly no readability. That is known as extremely turbid water.

Merely put, turbidity refers to how clear or “muddy” water is. And whereas the expertise to deal with turbid water exists, when turbidity is excessive and unlikely to settle anytime quickly due to constantly pouring rain, it turns into very tough to scrub and provide to customers at a traditional price.

From Dam to House

Okay, so the water is soiled and tough to deal with at an everyday tempo, thus the constriction and regulation of provide to make sure constant high quality. However how come some water service suppliers don’t halt water provide even when turbidity is excessive?

Nicely, it is because some water service suppliers have an enormous impounding reservoir for uncooked water. When the uncooked water coming from dams is saved inside a reservoir first earlier than it’s allowed to enter a therapy facility, extra sediments naturally settle to the underside by gravity. The outcome: Uncooked water turns into much less turbid, permitting for simpler and less expensive therapy.

Water service suppliers that aren’t afforded the posh of an identical impounding reservoir for uncooked water find yourself immediately receiving muddy water from the dams through the wet season. This extremely turbid uncooked water is tougher to deal with. The outcome: Decrease water manufacturing resulting in service interruptions.

So why don’t they only construct a reservoir for storing uncooked water? The quick reply is that there’s merely no house for one. A whole bunch of hectares of unoccupied land close to the therapy services could be wanted. With our nation as densely populated and extremely urbanized as it’s, one could be fortunate to have land for a tiny home.

Therefore, the one choice for water service suppliers that don’t have a storage facility for uncooked water is to spend money on costlier therapy applied sciences.

Addressing water shortages

The excellent news is that investments for higher water therapy are being made, as water service suppliers are conscious of the affect of local weather change and environmental degradation on our nation’s uncooked water sources. Such investments are wanted for long-term water safety.

Meantime, water customers can do one thing to ease the impact of water provide interruptions ensuing from extremely turbid uncooked water. A precaution we will take is to at all times have a provide of water saved for emergency use. And ensure to retailer simply sufficient water for when the service might be disrupted. It’s because the scheduled service interruption may lengthen if all customers draw an excessive amount of water concurrently in a panic.

A great tip would even be to comply with your water service supplier on social media as they often announce particular schedules by these channels.

All that being mentioned, with all these investments and ongoing upgrades, the time will certainly come once we received’t have to fret about opening an empty faucet anymore.
