East Dunne Water Transmission Line Installation

Project Overview

The East Dunne Water Transmission Main Line Project will construct approximately 4000 feet of 16" water transmission piping along East Dunne Avenue.  The pipeline will start at the existing East Dunne Booster Station, near the corner of Thomas Grade and East Dunne and continue southeasterly along East Dunne Avenue to serve a future 850,000 gallon storage reservoir site located east of Flaming Oaks Court. The transmission piping will connect to each of the side streets along its path to provide system redundancy. Construction activities are expected to start August 8, 2016 and continue through December 2016.  During the construction East Dunne Avenue will be reduced to one lane of traffic during the hours of 8:30am - 4:30pm, Monday through Friday.

This project is one of many projects to enhance fire fighting capabilities, enhance water system reliability and provide water redundancy in the Holiday Lake, Jackson Oaks and Jackson Meadows neighborhoods, see Plans.


Weekly Project Updates

Week of December 5, 2016
East Dunne Water Main Project:  With the exception of work to complete the installation of Pressure Reducing Valves (PRV) at Gallop Dr. and Vista Del Valle the project work is essentially complete.  The Contractor was given a punch list of items that must be repaired/completed prior to project acceptance.  The list includes items such as raising water valves lids in the street to meet the repaved asphalt roadway and installing concrete and bollards around new fire hydrants.  Weather permitting the Contractor should have these items completed by mid-December. 

Week of November 14, 2016
 
East Dunne Water Main Project:  The Contractor completed the installation of the 16” main line piping on E. Dunne Avenue and it has passed water quality and pressure testing.  This week the Contractor is connecting the side street piping to the new water main.  It has taken longer than expected because of the significant concrete surrounding existing piping.  Work will continue into next week with connections to the new Pressure Reducing Valves (PRV) at Gallop Dr. and Vista Del Valle.  Weather permitting the Contractor will be grinding and repaving the disturbed pavement along E. Dunne Ave.  Paving is expected to continue into Monday and Tuesday of Thanksgiving Week (November 21st and 22nd).  All work should be completed by the Wednesday, November 23rd before Thanksgiving Day.  Please understand that these dates may change if unforeseen conditions arise.

The City continues to work with the Contractor to minimize any disruption to our residents that these water shut downs might cause.  Please Drive Carefully Through The Construction Zone.  The speed limit through construction zones is 25mph unless posted otherwise. For your own safety and the safety of the workers, please slow down and observe traffic control/lane closures/other drivers around and through the construction zone.  For more information and weekly updates please check the following link http://www.morgan-hill.ca.gov/1551/East-Dunne-Water-Transmission-Line-Insta
 

Week of November 7, 2016

East Dunne Water Main Project:  The Contractor completed the installation of the 16” main line piping on E. Dunne Avenue.  The water main passed the pressure test and the water quality sampling is underway.  Work will continue on the side streets in order to make the water tie-in connections.  Between November 1 and November 11, weather permitting, the City and the contractor will be scheduling water shutdowns in order to make these critical tie-ins,  http://www.morgan-hill.ca.gov/DocumentCenter/View/19917.

Week of August 15, 2016 - The project is on schedule. The Contractor will continue utility potholing, project layout, and pavement sawcutting activities along the path of the new 16” PVC piping on E. Dunne Avenue. Potholing is the process of field locating the existing utilities and depth being crossed by the new piping. Pavement sawcutting is needed in order to remove the pavement section to install the new pipeline. The Contractor anticipates trenching for the new water mainline on or around Wednesday, August 24th. 
  
Week of August 8, 2016 - Construction activities will commence. Activities could include; USA locate, potholing to locate existing utilities and pipeline layout. Traffic control will be in place. Various color markings will be painted on the ground to identify the underground utilities, such as water (blue), sewer (green), electrical (red), gas (yellow), storm drain(orange) and communications (orange).
