When should I pay my bill?

Payment should be made within 24 days of the Bill Date. If your payment is made later than that, your new bill may be generated before payment of your previous bill is received, and your payment will not be displayed. If this happens you can verify receipt of your payment, and get your up-to-date balance, by selecting the MyOnlineBill link on the PWD home page. First time users will need their PWD bill to register. If you are already registered, just log in with your username and password.

Why did I get a late fee?

A late fee or penalty can be charged when your unpaid bill is at least 30 days old.

My bill says I have a credit balance, what does that mean?

A credit balance will occur when you pay more than the amount you owe, or if we adjusted your account because we over billed you. The Total Amount Due on your bill payment stub will have a CR after the amount.

Are there pharmaceuticals in my drinking water?

Last year Associated Press news reports shed some light on the widespread concern that medications are being detected in the drinking water of our nation’s largest cities. Major sources of pharmaceuticals in waterways are direct discharges from wastewater facilities and septic systems – either from people flushing unused medications down the toilet or from unabsorbed drugs being excreted from the human body.


Is there lead in my water?

There is pink slime in my shower. Is it caused by my water?

No, certain species of airborne bacteria gravitate towards and thrive in a moist environment, such as showers, toilet bowls, sink drains, tiles, and dog dishes. These slimes are naturally occurring and can be unattractive but are generally harmless. The best way to avoid this problem is to keep these surfaces free from the bacterial film through regular cleaning using Lysol or a chlorine-based product.

Is water treated with chlorine safe to drink?

Yes. Many tests have shown that the amount of chlorine found in treated water is safe to drink. Chlorine is needed to maintain disinfection throughout the distribution system. The potential for water contamination when chlorine is not used, outweighs any long-term concerns.

Why does my water sometimes look cloudy?

The cloudy water is caused by tiny air bubbles in the water similar to the gas bubbles in beer and carbonated soft drinks. It is particularly noticeable in water taken directly from the tap. Within seconds, the bubbles rise to the top and are gone. This type of cloudiness occurs more often in the winter, when water temperature is colder, and does not indicate any problem with the water.

What is the hardness of my water?

Hardness levels in Maine waters are generally low but can range from near zero to several hundred milligrams per liter as calcium carbonate (mg/L as CaCO3), the standard unit for hardness. The Greater Portland water source (Sebago Lake) has a hardness value of 9 and is described as soft, as you can see from the following table.


There is a blue-green stain where my water drips into my sink. What causes this?

This stain comes from the chemical copper. Copper is present in your home plumbing and can dissolve into the drinking water. If you would like to have your water tested for copper, or lead, please contact a customer service representative at the Portland Water District.
