DECATUR - Beginning Sunday in DeKalb County, any house built before 1993 and sold will have to have low-flow toilets that consume 1.6 gallons of water or less per flush.<br />
<br />
Low-flow toilets became mandatory in new construction around 1993, which is why officials picked that year. The county still has as many as 165,000 houses built before 1993, but no one knows how many have been upgraded with toilets that use less water.<br />
<br />
The low-flow requirement is one thing the county is using to cope with the drought.<br />
