Re: Modification Request to Permit No. WQ0039131-Modification
Orange Water and Sewer Authority
Hillsborough Street Water Main Replacement Project
Wastewater Collection System Extension Permit
Mr. Robinson:
Orange Water and Sewer Authority (OWASA) hereby request a modification to existing Permit No.
WQ0039131-Modification issued on November 20, 2017. During construction, a utility conflict prevented
full installation of the approved sewer. After evaluation of potential options it was determined that
adjustments to upstream and downstream sewer outside the approved permit coverage will be necessary.
The following modifications are hereby requested:
• Remove and reinstall sewer installed under approved Permit No. WQ0039131-Modification to
avoid utility conflict.
• Replace approximately 48 LF of existing 12" DIP immediately upstream of the permitted sewer
replacement.
• Install approximately 135 LF of sewer immediately downstream of permitted sewer replacement.
This will be a completely new sewer alignment and will consist of 15 LF of DIP and 120 LF of
stainless steel sewer piping. 23 LF of the stainless steel segment will be an aerial crossing. This
sewer has been noted as a High-Priority Line in Section IX.6 of the sewer extension permit
application provided within.
• The new sewer alignment mentioned above will allow the existing 12" DIP sewer immediately
downstream of the permitted replacement to be removed. This work will include removal of
approximately 110 LF of existing DIP and the associated concrete piers.
