The District is making needed improvements to the water and sanitary sewer infrastructure. The District has approved the following Fiscal Year 2018‐2019 capital improvement projects to increase the safety and reliability of the water and sanitary sewer system. Total cost: $1,639,000.

The current projects include:


Skyline Tank No. 3

Skyline Tank No. 3 exterior walls are showing signs of corrosion from the wind and ocean. This project consists of recoating the interior and exterior of the tank, appurtenance improvements to increase tank reliability, and a new drain outlet.

PROPOSED IMPROVEMENTS
• Structural improvements to withstand the design level earthquake
• Recoat the entire tank exterior and interior roof
• Various appurtenance upgrades

PROJECT BENEFITS
The Skyline Tank No. 3 Improvements protects and extends the tank's service life, ensures tank integrity following the design level earthquake, provides tank isolation during a seismic event, and reduces water waste.

Athy Drive Water System

Athy Drive Improvement MapThis project is to eliminate a cross country 8" asbestos cement pipe (ACP) which exists between Athy Drive, Carter Drive, and Meath Drive at and near the Skyline Village Subdivision. Click on map for larger detail.

PROPOSED IMPROVEMENTS
• Abandon 1,000 LF ACP
• Replace 150 LF of 2" PVC with 300 LF 6" DIP
• Replace 400 LF of 6" and 8" ACP with 8" DIP
• Replace 600 LF of 12" ACP with 12" DIP
• Relocate meters
• Replace 5 fire hydrants (2 Private and 3 Public)

PROJECT BENEFITS
The Athy Drive Improvements eliminates a CC water main, replaces aging water mains, and reduces District maintenance. The private water system will be maintained by Skyline Village.


Westborough Sanitary Sewer Lift Station

The valves are old and operation is becoming difficult and replacement is recommended. Automatic Transfer Switch and Motor Control Center also require replacement. The Westborough Sewer Pump Station Improvements decreases the risk of pump failure and down time.


Rowntree Sanitary Sewer Lift Station

The valves are old and operation is becoming difficult and replacement is recommended. The Automatic Transfer Switch also requires replacement. The Rowntree Sewer Pump Station Improvements decreases the risk of pump failure and down time.


Rowntree Pump Station Structural Analysis / Repair

Rowntree Pump Station is located along the northwest side of Gellert Blvd. directly across Rowntree Way. The pump station is a precast concrete structure built into the hillside with a concrete roof, rear and side walls dueling as retaining walls with the front exposed to the parking lot. There is also a wet well located directly behind the pump station between the building and sidewalk along Gellert Blvd. The pump station is accessed from the shopping center parking lot to the south. Over the years, the joint between the concrete roof and back wall has been leaking during rain events or when the wet well is full. It is also not known when the last structural analysis was performed on the building. This project involves performing a structural analysis of the building in addition to repairing the leak.


Avalon Sewer Pump Station Improvements

The Motor Control Center (MCC) panel and associated outdoor cabinet will be redesigned and replaced as they are in very poor condition. The Avalon Sewer Pump Station Improvements decreases the risk of pump failure and down time.


Westborough Blvd. Phases 1-3 Sanitary Sewer Improvements

One of the District's primary sanitary sewer (SS) mains, a vitirified clay pipe (VCP) varying between 6" and 10", runs along Westborough Blvd for approximately 4,100 LF between Skyline Blvd and the Westborough Pump Station located adjacent to the District office. In 2017, CCTV video determined the pipe showed a high frequency of internal defects including circumferential and longitudinal cracks, fractures, broken pipe, root intrusion and root balls, offset and separated joints - with some very severe. Although some sections of main have minor to no defects, the entire pipe should be replaced holistically. Due to it's length, replacement is recommended over three separate phases. P

Phase 1 replaces ±1,640 LF of deteriorating sanitary sewer main greatly reducing future maintenance and extending overall system life. Phase 2 replaces ±1,500 LF. Phase 3 replaces ±1,920 LF. For budgeting purposes, this project assumes open-trench construction and replacement with polyvinyl chloride (PVC).


Shannon Dr. & Vicinity Phases 1-3 Sanitary Sewer Improvements

Shannon Dr has ±5,400 LF of 6" and 8" vitrified clay pipe (VCP) sanitary sewers (SS) serving ±180 residents. In addition, 6 shorter sewer mains located on Olympic Dr, Wentworth Dr, Turnberry Dr, St. Cloud Dr, Orrey Way and Albright Way, collectively called "Vicinity", all connect to Shannon Dr over a total 1,100 LF of 6" VCP SS. In 2017, CCTV video determined the pipe showed a high frequency of internal defects including circumferential and longitudinal cracks, fractures, broken pipe, root intrusion and root balls, offset and separated joints - with some very severe. Although some sections of main have minor to no defects, all pipe should be replaced holistically. Due to it's length, replacement is recommended over three separate phases.

Phase I replaces replaces ±2,100 LF of deteriorating sanitary sewer main greatly reducing future maintenance and extending overall system life. Phase 2 replaces replaces ±2,260 LF. Phase 3 replaces ±2, 180 LF. For budgeting purposes, this project assumes open-trench construction and replacement with polyvinyl chloride (PVC).


Oakmont Dr. Sanitary Sewer Improvements

Oakmont Dr has ±1,060 LF of 6" vitrified clay pipe (VCP) sanitary sewers (SS) serving ±34 residents. In 2017, CCTV video determined the pipe showed a high frequency of internal defects including circumferential and longitudinal cracks, fractures, broken pipe, root intrusion and root balls, deposits, grease, and offset joints - with some very severe. Although some sections of main have minor to no defects, all pipe should be replaced holistically. This project replaces the existing sewer main in addition to replacing/rehabilitating laterals and manholes. For budgeting purposes, this project assumes open-trench construction and replacement with polyvinyl chloride (PVC).

The Oakmont Dr Sanitary Sewer Improvements replaces ±1,060 LF of deteriorating sanitary sewer main greatly reducing future maintenance and extending overall system life.


Bantry Ln. Sanitary Sewer Improvements

Bantry Ln. has ±1,200 LF of 6" vitrified clay pipe (VCP) sanitary sewers (SS) serving ±44 residents. In 2017, CCTV video determined the pipe showed a high frequency of internal defects including circumferential and longitudinal cracks, fractures, broken pipe, seal ring protrusions, and offset/separated joints - with some very severe. Although some sections of main have minor to no defects, all pipe should be replaced holistically. This project replaces the existing sewer main in addition to replacing/rehabilitating laterals and manholes. For budgeting purposes, this project assumes open-trench construction and replacement with polyvinyl chloride (PVC).

The Bantry Ln. Sanitary Sewer Improvements replaces ±1,200 LF of deteriorating sanitary sewer main greatly reducing future maintenance and extending overall system life.
