Upper Lakeview/Rigi Pressure Reducing Valve (PRV)                      01/25/19

Project Description and Cost Detail        

Scope Described

Update PRV set up by separating the lines between the zones covered by this PRV.  This project is a high priority as customers are negatively impacted by water pressures in this zone.  Separating the lines will allow for reduction of pressure to customers on Lakeview and Oak Ridge while maintaining and supplying adequate pressure to customers on Upper Lakeview.   

Separation of lines into 3 segments complies with the 2005 Water System Master Plan as well as allows for improved metering of zone to aid in leak detection and updates valve access when reading meter.  Also allows for improved access when an adjustment is needed to the PRV for pressure stabilizing within zone. 

Cost Detail

$36,140 for PRV pit #1

Excavation (3 days)                                         $9,500

Vault with ladder                                             $7,600

PRV pit #1 proposed for 2019; remaining work to be proposed for future years.

Remaining work for this zone:

 $34,700 for PRV pit #2

$34,700 for PRV pit #3

Funding will be from water usage fees. 

All figures are from contractor quotation and equipment price from the supplier; ledge blasting is estimated.  If the $5,000 for ledge removal is not used, the funds will be placed into the water system Capital Reserve Fund. 

Muddy Beach 5,000-gallon tank replacement                               01/25/19

Project Description and Cost Detail        

Scope Described

This warrant article proposes to replace the existing Muddy Beach 5,000-gallon tank in 2019. Muddy Beach is the secondary source of water for the District and supplies 15 to 20% of the water needs for the Village District.

The tank at Muddy beach is not a water storage tank by today’s standards, it is actually a WW II marine buoy modified years ago for the Village District water supply. The existing modified vessel does not have an access panel for inspection and cannot be re-lined. State recommendations (regulations do not apply to tanks under 10,000 today) recommend all water tanks be inspected this cannot be accomplished with the existing unit. Replacing this vessel with a new tank is a Village District priority to secure water from a secondary source prior to completing work on other water system components to insure minimal impact on the district residents.

Expending funds on old equipment that has not been inspected is not viewed to be in the best interest of the District, therefore, replacement with a known entity that will be properly maintained for maximum life expectancy is recommended. 

Capital Improvements completed at Muddy Beach well in the last few years allowed Muddy Beach to supply the District with water during the recent 4-day DPW well outage which included two of the highest water usage days annually.

5,000-gallon tank & materials                                     $19,100

Reinach 90,000-gallon cast-in-place concrete tank                     01/25/19

Project Description and Cost Detail        

Scope Described

Replace the two 30,000-gallon steel tanks which failed inspection during 2018 with one 90,000-gallon cast in place concrete tank.  This project will comply with the NH DES water storage requirements as well as create the Reinach Pressure Zone which is needed to supply adequate pressure to the houses at the higher elevations near the Reinach tank.  

Creation of the Reinach Pressure Zone will impact houses located on the upper section of Aspen, Bristenstock, Reinach, Biasca, and Adelboden are all impacted by reduced pressure; 30-35 houses.

This proposal is the lowest cost alternative for replacing the water storage tanks and creation of the Reinach Pressure Zone. 

Cost Detail

$653,400 as shown on Engineer’s Estimate spreadsheet

Funding to be raised from a 20-year bank loan at 3.13% interest with a first year’s payment of $50,300

DPW Electrical Upgrade                                                                          01/28/19

Project Description and Cost Detail        

Upgrade of electrical systems and components at the DPW Well site.  This is a high priority as a result of the inability to maintain water supply should the DPW well be out of service due to an electrical failure.  Project corrects noted electrical code deficiencies found during the review by Electrical Engineer. 

Scope Described

Upgrade water system electrical to 480-volt service; add lightening protection for DPW well; upgrade pressure transducers; replace panel with one of proper size and add proper surge protection and grounding; add variable frequency drive control for DPW well; add proper surge protection for water computer in office.

Addition of VFD drive is anticipated to create a significant savings in electric.  In 2018, Jungfrau pump house used 30,978 kw hours where as DPW used 56,417 kw hours as shown on electric usage chart below.  Jungfrau pump house has 2-20 HP pumps where as DPW has only one; yet the DPW pump cost $4,962 more to run per year.

Break even from savings in 13 years.

Break even from line item in 2 years.
