I'm in California.  Our water system is "a drought."

An entire State would have one water system??  We have municipal water systems, drilled wells, dug wells, shore wells, cisterns, river systems . . .

I don't understand this question. I'm from North Carolina... we have public water, we have community wells, we have private wells, etc. What state would have just one water system?

I second, Ryan Huggins - Thousand Oaks, CA 's answer.  I think each city has their own system, as least Santa Barbara does, and all our city landscapes are watered with recycled water.  A

There are NO "state" water systems I am familiar with.   Normally, they are controlled by a local water authority, a municipality or properties have an individual or community well.   Our home, here in Virginia, is on a community well system that my husband maintains.

I'm reading into YOUR question here but water "quality" is a current and appropriate concern.   Buyers should always request a water quality test, NOT by the water provider, but by an independant agency like a health dept. or other testing facility; of water drawn from the tap at the property.

With ALL the problems in the news, I think I would make that a standard clause in my contract offers if I was a buyer's agent.   I suggest it to MY borrowers all the time if they haven't already requested it !

State?   Not in Florida.   Different cities and towns, different communities do it different ways.  We are on a well.

Ruth Mary Hansen I work and live in Atlanta.  We have public water and buyer would have to work with each county for water sevice. 

VA. Most wells or public. A few older homes still use spring water.

We have county water in some places, city water in some places, private water systems with multiple homes in some places, shared wells in some places and private wells in some places. The state has nothing to do with it.

In the areas of Maryland I serve, we have public water supplies and wells.

public from Lake Michigan Evanston IL and Chicago land

I'm in CO. We have all kinds of water. I have a mountain property with a well, because there is no domestic water supplier for that area. We also have large and small domestic water companies. And then there's irrigation water. 

As tiny as Delaware is, we have a variety of water systems. Depending on the size of the lot and the availability of public water, you might have a well, or have water made available through a municipatlity or a private water company.

It flow freely through the water table, we stick a pipe in the ground and pump it up.

The Colorado River feeds AZ and several other states . . . water is like gold here.

Rain!?   Cities have wells or rivers and lakes...rural properties have wells

The good kind, filtered and chlorinated. I'm from another state, but live in Illinois.

I do not understand this question.

A good one.  In Arizona.

Albuquerque gets it's (City) water for the Aquifer, Rio Grande and Rio Chama.  

Wherever I have lived, the water has always had a "taste" to it. In Hawaii, it tasted like fresh rain. Here in Riverside, CA, its okay but has a signature to it

Here in NH the cities have municpal water, most often from a lake. The rural homes most often will have drilled wells. 

That depends on the municipality. Sarasota is well and river.

Carlsbad is reservoir, well and De-sal.

I can answer you question what state I am from (Tx); however I don't understand you question about water system.

In my local area, we have mostly wells and septics, but that is not true in all of Connecticut.

Our town has homes with public water as well as there are homes with wells.

Florida - municipal water is most common, with some rural areas still on individual wells!

I do not fully understand the question.  

My state is composed of several islands so no shared system. My island has different systems depending on location.

We have Cumberland Tea here in the Nashville area.

Our water source would be rivers and through public authorities we get treated water. Not many places in Montgomery County TN (Clarksville) use well water because "city" water is so readily available.

Well water, CA.
