All required information must be submitted to our office prior to the issuance of a new service permit, or before the meter size may be released to Johnson County Wastewater (JCW). We ask for 10 working days review time to provide initial comments but strive to get them sent back as quickly as possible. Please keep in mind very large projects, like a Hospital, might take additional time.  Our plan review includes a compliance check for cross connection control. For more information about cross connection control, see our Preventing Backflow page.

Please only submit electronic plans on a disc or by email to distserv@waterone.org. Plans submitted via email must be in standard PDF format with a maximum size of 25mb. For IT security reasons, WaterOne cannot accept zip files or files via external download links such as Dropbox.

Sizing

Meter
WaterOne will provide the minimum size of water meter based on water supply fixtures and probable demand according to the 2012 International Plumbing Code (IPC). For redevelopment of properties with an existing water service, WaterOne will confirm the meter size is appropriate.  

Service Line
WaterOne will provide the minimum size of service line required from the water main to the entrance of the building.  The size of the line does not account for losses through a backflow preventer or the height of the building. If requested, applicants may install a larger service line.
