Purchased Water and Groundwater

The city purchases its water from Gwinnett County Water Resources through a multi-year wholesale contract. The city has seven inter-connections with the Gwinnett County distribution system. Each inter-connection is equipped with a meter, backflow device, and a pressure transducer. We monitor and record the inlet pressures at all inter-connections. The source of the water from Gwinnett County is Lake Lanier and the water is of a very high quality, meeting or exceeding all standards for drinking water. The City produces @5% of its 2 million gallons per day (mgd) water demand from two different wells. One well is located at Rhodes Jordan Park and the other is located off Old Norcross Road. The remaining 95% is purchased from Gwinnett County Water Resources. During 2008, the city purchased 670,340,000 gallons of water from Gwinnett County and produced 49,010,820 gallons from its one well. The combined total water provided in 2008 was 719,350,820 gallons or @2. mgd (million gallons per day). The city has one permanent water treatment plant located in Rhodes Jordan Park that produces @ 144,000 gallons per day (gpd). This plant utilizes two wells that were drilled in 1914 and 1947 respectively. These wells are connected by a fracture in the rock formations that is approximately 12 feet high at approximately 90 feet below land surface. Due to this connection, these two wells cannot be pumped at the same time. The Rhodes Jordan Water Treatment Plant utilizes pressurized, multi media, greens and filters to remove ferrous iron and manganese from the well water. Chlorine gas is added to the water for disinfection.  Potassium permanganate is added to the water to assist in iron and manganese removal and to recharge the greens and filters.  The City also has a temporary treatment facility located off Old Norcross Road.  This well has been in service since August of 2008 and produces approximately 80 gallons per minute.  We add chlorine for disinfection and a phosphate to sequester the iron.  The City is currently pursuing the use of additional wells to supplement the daily demand.  We have hopes that we will be able to produce in excess of 50% of our daily demand from groundwater.

 


 

New Groundwater

The City is currently in the design phase of a new treatment facility to be located on Winer Industrial Way.  The new potential will utilize up to 8 new wells that are dispersed around the central and western portions of the City.  The new treatment facility will utilize treatment systems to remove iron and manganese as well as low levels of Radium 226 and 228.  A 1 million gallon storage tank will also be constructed on site which will double the storage capacity for the City.
The City is also in the design phase of adding an additional well to the existing Rhodes Jordan Water Treatment Facility.  The new Ezzard Road well will add an additional 100 gallons per minute.  Additional treatment for radionuclides will be added at the well site prior to transmission to the Rhodes Jordan Water Treatment Facility.
 



Water Quality

Treated water samples are collected by the plant operators from the distribution system on a regular basis as required by the by the Georgia Drinking Water Act 391-3-5-25. An independent laboratory, certified by the EPD, conducts analysis for some of these tests and the State laboratory conducts others.  The plant operators gather all samples. There are numerous tests required at certain times during the year and some on a daily basis. The city operators conduct real time, continuous water quality testing at the plant as required by the EPD. These test results are recorded on a daily log to ensure public safety. Gwinnett County plant operators conduct all tests as required by the EPD at their lab on the water supplied to the city. The city reports to the public on the water quality of the distribution system and the plant through its Consumer Confidence Report published every year and mailed to each customer with their May water bill every year.



Distribution System

The city water distribution system consists of a variety of water lines in both size and material.  These lines range from 2” to 16” in size and made of polybutylene, plastic, galvanized, cast iron, asbestos cement, and ductile iron. The city has a good over all distribution system that works well, however, there are some areas that need to be upgraded in both size of the water main and the type of material the pipe is made of. The city has recently contracted with an engineering firm for a new hydraulic model of the system to help identify problem areas and potential problem areas. Once this model is complete, the city will contract out the new water lines to be replaced and begin to replace the old lines on a priority basis.  The city is also nearing completion of a two-year project that involves meter replacement and installation of radio reading devices on all of its @ 7,000 meters. This will not only regain lost revenue, but it will help identify water accountability issues.  This is the first meter replacement in the city history.



Storage

Water storage consists of (one) 1 mg standpipe water tank located on Oak Street. This tank was built in 1964 and is 104’ tall.  Its original design was to balance the distribution system and fire protection. Due to the high pressure provided by GWCPU, the tank stays full except in the case of a main line break or an emergency. Divers inspect the tank every other year and the tank is in good shape.  The water tank was repainted inside and outside in early 2006.

Water Conservation

The City of Lawrenceville recognizes the importance of water conservation as a vehicle for preserving its precious resource for future generations. The extreme five year drought that rocked Georgia at the end of the 1990’s is still fresh in our minds. The city saw a drastic reduction in water use from 2000 to 2004 as the citizens demonstrated an acute awareness of the drought problem by actually reducing water consumption from a daily average of 2.4 mg to 1.7 mg during these years. However, through development and with non drought conditions, the consumption numbers have crept back to 2.3 mg during 2005. The City plans to adopt a multi tiered water rate system designed to create incentives for curtailing residential and commercial irrigation during peak summer months.

For usage greater than 10,000 gallons and which exceeds average winter (Jan. Feb. and Mar.) usage as follows:

First Tier greater than 125% but less than 200% will pay at 25% higher than the current monthly rate per 1000 gals.

Second Tier will be for customers that use 200% more than the winter month average winter usage they will pay 100% higher than the current monthly rate per 1000 gals.
