Sienna MUDS

Sienna Municipal Districts

Sienna residents' water, sewer, and trash services are managed by the multiple municipal utility districts (MUD) located throughout Sienna (resident MUD districts are generally based on geographical location of neighborhoods).  Each MUD contracts with Si-Environmental as its operator in providing these services to residents.

In addition, each MUD is represented by individual Boards of Directors, many of whom are elected by residents within those districts.  Each Board is responsible for managing the District's assets and related district projects.  The MUDS meet monthly.

The Sienna MUD districts each utilize individual websites to convey information or updates to their constituents.  The Association encourages residents to check on these sites periodically for MUD updates.  Note:  These sites are operated by a third party entity under contract to the MUD, not by the Sienna Associations.
