(1) During the year 2002 we built a 400,000 gallon storage tank and installed approximately 40 miles of water mains. The flushing and filling of tank and lines caused a good percentage of this unaccounted for water.

(2) The Institutional connections for Gates County are 4 connections billed as 1 connection to the Gates County Board of Education.

Does this system have a wellhead protection program?   No

(1) On our Number 2 Well the information given may be confusing. We have two screens in this well. One screen is located at 220 feet and it is a 10 foot screen. Then we have a casing. At 380 feet we have another 10 foot screen that brings the total well depth to 400 feet.

(2) In mid 2002 we started monitoring the withdrawals and days the three wells were being used. Therefore the answer is unknown for average daily withdrawals and maximum daily withdrawals because there is not a completed year of data.

(3) Number 1-3 Wells Average Daily Withdrawal was determined by dividing the 2002 Average Annual Daily Water Use among the three wells.

Did average daily water production exceed 80% of approved plant capacity for five consecutive days during 2002?  No
     If yes, was any water conservation implemented?  
Did average daily water production exceed 90% of approved plant capacity for five consecutive days during 2002?  No
     If yes, was any water conservation implemented?  
Are peak day demands expected to exceed the water treatment plant capacity in the next 10 years?  No

We call our water plant a water treatment plant but in reality we do not treat any water, we only add chlorine as a disinfectant.

(1) The institutional projections have been updated to account for growth approximate to the residential projections.

(2) Typically, water supply systems should be less than 10% for unaccounted-for water projections. The projections for 2010-2050 are in agreement with this guideline and with the 1997 LWSP estimated unaccounted-for water use. The significantly higher 2002 unaccounted-for estimated water use is a result of the installation and subsequent flushing and filling of a 400,000 gallon storage tank and approximately 40 miles of water mains.

The purpose of the above chart is to show a general indication of how the long-term per capita water demand changes over time. The per capita water demand may actually be different than indicated due to seasonal populations and the accuracy of data submitted. Water systems that have calculated long-term per capita water demand based on a methodology that produces different results may submit their information in the notes field.

Your long-term water demand is 72 gallons per capita per day. What demand management practices do you plan to implement to reduce the per capita water demand (i.e. conduct regular water audits, implement a plumbing retrofit program, employ practices such as rainwater harvesting or reclaimed water)? If these practices are covered elsewhere in your plan, indicate where the practices are discussed here.    

Are there other demand management practices you will implement to reduce your future supply needs?   

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   

How does the water system intend to implement the demand management and supply planning components above?   

Additional Information

Has this system participated in regional water supply or water use planning?  No

What major water supply reports or studies were used for planning?  none

Please describe any other needs or issues regarding your water supply sources, any water system deficiencies or needed improvements (storage, treatment, etc.) or your ability to meet present and future water needs. Include both quantity and quality considerations, as well as financial, technical, managerial, permitting, and compliance issues:   At this time we do not see any increase in needs that we cannot handle.
