Cities that transport their septic tank sewage to Richfield will be paying as much as 12 times more for its disposal.

And many communities won't be able to continue using Richfield's waste-disposal facility to get rid of such sewage after the Richfield City Council decided to discontinue accepting waste from areas as far away as Utah and Carbon counties.The price of sewer and water connection fees for undeveloped properties is also going up in Richfield, in some cases nearly doubling. But residents needing water connections on developed properties will get fee reductions.

The City Council has approved the charge for septic dump fees at $180 per load, up from $15. The areas from which such sewage loads will be accepted is also being greatly reduced.

The city has been accepting septic tank sewage from communities, including Spanish Fork and Price, in more than a half-dozen counties. Some 221 dumps were accepted last year and 238 dumps in 1993, according to city employee Chuck Pollock, whose work involves the sewer system and lagoons where the sewage is processed.

Septic tank sewage will now be accepted only from areas in Sevier and neighboring Wayne and Piute counties.

Pollock fears the sewer system may fail if the current disposal volume continues. He explained the lagoons don't work well in the winter when the water is cold. And, the system must rely on the right water flow and bacterial activity for proper functioning.

Furthermore, Pollock noted that the bacteria necessary for the system to work properly is killed by chemicals that are used to control odors in non-flushing and portable-type systems.

Meanwhile, it will cost owners of undeveloped property as much as $550 more for sewer connection fees in Richfield.

The price will be more than double for hooking up with a 4-inch line, rising from $450 to $1,000, while the costs for a 6-inch line increased to $1,100 from $600.

Water connection fees have also been hiked on undeveloped properties with smaller than a 2-inch meter. The 3/4-inch meter fees will go from $450 to $700, 1-inch from $550 to $800 and 11/2-inch from $1,200 to $1,800. Fees for 2-inch meters remain at $2,250.

The connection fee structure is much different on developed property, however, substantially declining.

Cost for a 3/4-inch meter and connection fee will be reduced from $450 to $75, 1-inch from $550 to $125, 11/2-inch from $1,200 to 350, and a 2-inch meter from $2,250 to $500. The fee will be based on actual cost for larger sizes.

Revenue from fee connections has failed to meet costs, according to Mike Langston, city finance director.

He said the City Council's goal was to develop a structure that covered actual costs. The new fees will largelycurtail losses, Langston added.
