(KMOV) -- St. Louis County emergency management officials are nearing the completion of a project to revamp the outdoor warning system.

The county bought 169 new tornado sirens and kept 16 old ones to make up a 185 siren system that's expected to reach 99.6% of people in the county.

The county spent around 7.5 million dollars on the project, after voters agreed to a 1/10 cent sales tax increase in 2009.

The old system was made up of 210 sirens, but the county says the old sirens weren't as effective and only reached about 88 percent of people in the county. The old sirens consisted of one speaker, that rotated. The new sirens resemble a beehive and are made up of 10 speakers stacked on top of each other.

The county still has to install two more sirens, but the system is expected to be fully operational by the end of the summer. A tentative test date is set for 11 a.m. on Labor Day. That's when officials will sound the sirens to make sure they are all working properly.
