Reviewing my JEA bill http://www.jea.com the sewer service charge for 8000gal is $39.61. The water service is $20.97. On 8k gallons at $39.61 = $4.95 per 1k gallons. Looking at my prior statements online the water usage and sewer rates go up in costs as you use more water. Looks like they have a pricing scale. Check your current statement against a (recent) older one that is similar in water usage for a comparison. Just remember they recently had price increases (don't recall when they went into affect). It's not a far stretch for JEA to have mis-billed you and for them to have not taken notice to it on your initial call to them.
