Updating septic system
I dont think adding a bath would make you change septic.the same amount of people would be living in home extra baths dont bring more waste water. It almost seems if you live any place around here and system is more then 7yrs old selling it means improving system.If you call an engineer or an excavator for an estimate, they will be able to tell you if you just need a larger tank/field, or a full system replacement.I needed a new system to go from 2 to 3 bedrooms, but the original system was a cesspool, so no other choice.Depending on where you live and the complexity of your project, you may need a building permit.A permit may add several hundred — or even several thousand — dollars to the cost of your overall project, but it and its accompanying inspections will help ensure your tank is installed according to code.
Also, if you have to sell the house in a hurry for any reason, you may be scrambling to do the septic in order to close a sale as a 3-4 bedroom.A septic tank riser allows above-ground access to your tank and can considerably reduce the cost of maintaining your system.Septic tank risers are commonly made from polyethylene, PVC or concrete.The Iowa Administrative Code (or IAC) 567-69 sets the State of Iowa wastewater regulations which are adopted by Story County and apply to construction of private sewage disposal systems.
The IAC 567-69 is available to download in the Regulations section of our webpage.All homes in Story County that are not connected to approved municipal, community, or group sewer systems are required to have private sewage disposal systems.
