[ARCHIVED] Harris Addition Sewer – Project Open House and Work Activities

The Town of Sunnyvale has contracted with an engineer to design the replacement of sanitary sewer lines in the Harris Addition.  We welcome members of the community to attend a Project Open House on Monday, Sept. 16.  The Open House will be come and go from 4 p.m. to 6 p.m. at Town Hall.

Upcoming Work:

CP&Y Inc. - Surveyors on Site – There will be survey crews on site for through approximately the end of October 2019. They will be obtaining property information and topographical information in all alleys and in selected streets where there are Sanitary Sewer Mains. The only streets involved that contain existing sanitary sewer mains are Mansfield Dr. and Tripp Rd. Property owners & residents may be of the opinion that their property is up to the street paving when it actually begins several feet away from the street or alley. Surveyors may be on the strip of Town-owned right-of-way outside the paving & may have the appearance of work on private property. Activities that may be observed by the survey crews include:

  • Crew truck parked in street or alley - May temporarily prevent through traffic in the alley
  • Personnel working with survey equipment in the alleys and streets – equipment consists of a mounted transit and a telescoping rod for measuring heights
  • Pull manhole lids to survey the existing sanitary sewer main components
  • Some work on the edges of private property to obtain location and elevations of structures and/or paving that may be impacted during construction
  • Slight excavations near existing property lines where the surveyor may be attempting to locate an existing rod at property boundaries – this should be minimal and readily restored by the crew

AIMS COMPANIES – Sanitary Sewer Main Cleaning and Televising Crews – The AIMS personnel are to begin in mid-September and are scheduled to be on site for

Approximately 5-6 weeks. Their work consists of cleaning the existing sanitary sewer mains located in the alleys and some streets. They will also be putting a television camera through the pipelines to evaluate the existing condition. Activities that may be observed by the survey crews include:

  • Parking a vehicle adjacent to an existing manhole and personnel located at a second manhole on the same pipeline – this may result in a temporary blockage to through traffic in the alley
  • Connecting a hose to an existing fire hydrant to gain access to water for the process of cleaning the mains – this should not affect traffic, but may be noticeable to citizens
  • It is possible that the effort to clean the pipelines may release blocked flow and cause sounds in the private plumbing – no flooding of private pipes should result

Both companies are required to have personnel and equipment that readily identify them and wear uniforms and safety apparel when working on the streets and in the alleys.

Neither company has authority to enter private property. Access to private property may be requested for the survey team in a location between homes where an existing sanitary sewer main exists. This will be coordinated through town staff.

If there are questions regarding this information, please contact Town Engineer Lyle Jenkins at (972) 203-4115 or by email at
