The City of Lawrenceville Water Department is responsible for providing city residents and businesses with a reliable supply of clean, high quality water.  The Water Department strives to provide responsive, consistent service throughout the city and to protect the public health and safety by using responsible and efficient water delivery and treatment systems. 

The Water Department takes an active role in planning for future growth and expansion.  This planning will ensure that the city has sufficient water and sewer capacities to support quality growth, while maintaining the integrity of the environment.  On average, each household in Lawrenceville uses approximately 210 gallons of water per day.  Residential water use was 75 gallons per capita daily (GPCD) in 1997. 

The City of Lawrenceville currently purchases approximately 85% of its water supply from Gwinnett County.  The county obtains water from Lake Lanier, which it treats at its Lake Lanier Water Treatment Plant.  Groundwater fills the remaining 15% of water supply needs and is treated at Lawrenceville's Water Treatment Plant No. 1.  This treatment plant is located at Rhodes-Jordan Park within the City of Lawrenceville.  The purchase of water from Gwinnett County is based on a wholesale agreement between the city and the county.  The city is billed for consumption; based on the readings of the city-county connection meters.  Water is transferred to the city through two peak meters and five non-peak meters.

The total annual water demand of the City of Lawrenceville is about 900 million gallons.  The average daily demand is 2.44 million gallons per day (MGD).  Maximum daily demand is 3.0 MGD.  Residential water use constitutes about 60% of the total and the balance is attributed to commercial and industrial activities.  All residential, commercial, and industrial users are metered.  Water demand increases 40% during the summer months.

The city's water storage facilities consist of a single million-gallon standpipe located on Oak Street.  The steel standpipe maintains pressure throughout the distribution system and provides fire protection.  The standpipe was constructed in 1966-67 and is equipped with an altitude valve, which prevents the tank from overflowing during low demand conditions.

The City of Lawrenceville built its first water treatment plant in 1993; for the purpose of supplemental emergency back up during summer high demand conditions.  Regular year round operation started in January 1996
