The average daily use of the institutional customers (2 churches at 0.00041 MGD) is too low to register in the data field. Also, LMAC has two industries that are connected to the system for fire protection only. These industries did not draw water from the system during 2002 and are not included in the total number of connections to avoid skewing the average usage of the customers who are regular water users.

Does this system have a wellhead protection program?   No

Wells not metered and therefore average daily and maximum day withdrawals are unknown. LMAC owns approximately 3,000 acres of land. Development of the land is controlled by the Commission. The Commission has not implemented a wellhead protection program because it controls land use around existing wells as well as the location of new wells.

     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

LMAC has two finished water elevated storage tanks, one 100,000-gallon and one 500,000 gallon. The system also has two raw water clearwells, 280,000 gallons each. Phosphate is added at the clearwells and chlorine and caustic are added between the clearwell and the elevated storage tanks. There are two chemical feed treatment systems, the old system and the new system. These systems are identified above in the water treatment plant section. The capacity of the chemical feed systems exceeds the current available supply, which will allow for growth in the system.

The goal of the LMAC is to foster industrial development in the area. The LMAC utility systems primarily serve industrial customers. A few residences have been served due to their proximity to the system, however there is no plan to extend service to additional residences. The purpose of the Laurinburg/Maxton Airport Commission is to encourage industrial growth in the area. The purpose of the LMAC water system is to provide water to new and existing industrial customers. Because of this, it is unlikey that additional residential customers will be connected to the system. Because the majority of the customers on the LMAC system are industrial, it can be difficult to accurately project future demands. Average daily industrial demand decreased from 1.137 MGD in 1997 to 1.05 MGD in 2002. It is likely that this decrease is due to the economic slowdowns impacting local industries. An average growth of 2.0% per year is used to estimate future demands on the LMAC system.

LMAC's average daily water demand will exceed 80% Demand as Percent of Supply by 2020. The authority owns approximatley 3,000 acres of land surrounding the airport facility; thereby providing adequate space for the installation of new wells as customer usage dictates.

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 33 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?   

LMAC's average daily water demand will exceed 80% Demand as Percent of Supply by 2020. As previously discussed, the goal of the LMAC is to foster industrial development in the area. Ensuring a reliable water supply is critical to retaining and attracting industrial and commercial development. The Commission has procedures to review demands and future needs. In addition, the Commission works with potential industries to ensure their utility needs can be met. The authority owns approximatley 3,000 acres of land surrounding the airport facility; thereby providing adequate space for the installation of new wells as customer usage dictates.

Additional Information
