All resources are naturally filtered. Water drawn from all of our deep wells is simply treated with chlorine as it enters the distribution system.

Hard Water

Water is considered "hard" when it contains a high level of dissolved minerals. The two nontoxic minerals that cause our hard water are calcium and magnesium which do not pose a health risk.

Effects of Hard Water

Hard water can make it difficult to produce a lather (or suds) while washing. It also can leave a chalky build-up on fixtures and spots on glassware. These effects are solely aesthetic and do not affect our health.

Alternatives

There are several alternatives to reduce problems associated with hard water. They include laundry detergents that include water-softening agents, dishwasher rinse aids, bath salts and lime- or mineral-dissolving household cleaners.
Deposits on fixtures and countertops can be prevented by wiping surfaces dry. Mineral residue on surfaces only occurs when water is allowed to evaporate.

Cloudy Water

Drinking water delivered through  our system can sometimes look "milky" or "cloudy." This cloudiness often occurs when air becomes trapped in the water. While this may impact the water's appearance, it does not affect the water's safety and will not harm household plumbing systems.

Source of Air in the Water

Air can be introduced in many ways, including the groundwater pumping process, water pipeline maintenance, or the process of bringing cold groundwater to the warmer surface.   Because water pipelines are pressurized, air remains trapped in the water until you open the faucet and release the pressure—similar to the effect created when you open a bottle of soda. The thousands of tiny air bubbles that form give the water a slightly white appearance.

Cloudy Water Test

There's an easy way to test whether cloudy water is due to trapped air. Fill a glass with tap water and set it on the counter. Observe the water for a minute or two. As the air dissipates, water should start to clear up.

Trapped Air & Water Quality

Cloudy appearance does not reduce the water's quality. Our water maintenance/ production personnel collect water samples for lab test every month from throughout the Water District's service area to ensure that tap water meets or surpasses the standards.

To ensure that our water meets or surpasses drinking water standards, TWD collects and submit samples to UP Lab for bacteriological and Chemical/Physical test. This is done monthly and twice a year respectively on more than LWUA required number of samples.

Newly installed main pipelines are also tested for bacteriological quality before they are accepted as part of our water distribution system.
