Fencing Along Calesetta Place

In 2018, fences were installed around the spray fields bordering Calesetta Place.  The fencing is required by the State Regional Water Control Board because the irrigation on this property is above ground unlike the underground irrigation between Chiavari Way and the railroad tracks.  OLWD uses the spray fields on Chiavari Way and Calesetta Place to dispose of recycled water from its wastewater treatment facility.  Once the OLWD connection to Manteca is in place, these spray fields will no longer be used and the fences will be removed.
