Dacula's water comes from Gwinnett County, which lists hardness at about 1.34 grains per gallon on average, which is soft, so most homes don't need a softener. Some Dacula properties are not on municipal sewer, which also argues against adding one. Call the number on this page to be connected with a local plumber in Dacula.

Signs that bring Dacula callers
- Chlorine taste in drinking water

Dacula's water
Dacula has no water department; its Non-City Utilities page lists Gwinnett County for water and sewer. Gwinnett draws from Lake Lanier, treats the water at its Shoal Creek and Lanier plants, chlorinates it and adds fluoride before it travels through the county's distribution system to Dacula. The county's water-quality page lists total hardness at 1.05 to 1.87 grains per gallon, averaging 1.34, which is soft. A softener rarely has much work to do here.
Dacula is a small, historic eastern Gwinnett town growing quickly, and its 30019 ZIP includes the large Hamilton Mill area. The median home was built in 1999, with about 12.5% predating 1980. The city's building permit application notes that some homes are not on municipal sewer and use private onsite wastewater systems, which need Gwinnett Environmental Health approval for new structures. On those properties, softener brine would go to the onsite system, another reason to skip a softener the water doesn't need. Gwinnett is responsible for the pipes that bring water to the meter; everything between the meter and the home is the homeowner's.
Cost factors
- Carbon filter size and location
- Bypassing or removing an existing softener
- Drain routing on a property off sewer
- Heater service if it's the source of grit
- Cartridges over time

You'll be connected with an independent plumber who serves Dacula. The City of Dacula issues building permits at City Hall, 442 Harbins Road, and does its own inspections through the City Inspector with 24 hours' notice. Its plumbing rough inspections check that water piping is strapped every 5 feet and that waste lines pass a water test. The plumber can tell you whether a treatment install needs a permit. Most Dacula visits end with a carbon cartridge, a heater flush, or a softener put on bypass so the household can judge whether it was doing anything useful.
