The ELVD water system recently violated a drinking water standard. Although this is not an emergency, as our customers, you have a right to know what happened, what you should do, and what we are doing to correct this situation.

On Sunday, April 7, a resident on Ellen Brook Road informed the ELVD that her water had a bad taste and was turning things blue. WSO+ (our water “department”) was informed of the issue immediately. WSO+ went to the residence, obtained a water sample, and tested it. It tested with a very low pH, which meant the pH monitor at the Meeting House Treatment Center was malfunctioning. The problem was corrected, a replacement monitor has been ordered, lines were flushed, and the problem was taken care of. We were not made aware of what the problem was until Monday morning, when a call was placed to WSO+, who informed us it was already fixed.
Your water is perfectly safe. The low pH was leaching copper from the pipes in people’s homes. If you didn’t have copper water pipes, there was no problem; hence the reason for the sporadic nature of the problem occurring.
Any future announcements of interest to District residents will be put on the ELVD web site only.
The Consumer Confidence Report (CCR) details the quality of your drinking water, where it comes from, and where you can get more information. This annual report documents all detected primary and secondary drinking water parameters, and compares them to their respective standards known as Maximum Con-taminant Levels (MCLs).

Summary Of Water Project
Background: The Emerald Lake subdivision was originally supplied with wells which connected to predominantly seasonal homes through 2 to 4 inch flexible tubing since the 1960s. This distribution system is failing and inadequate, as the community has grown into more permanent homes with year round residents. Therefore, the District has experienced a high level of leak occurrences which causes loss of treated water and are expensive to repair.
Moratorium: In 2007, the New Hampshire Department of Environmental Services (DES) Drinking Water Division, which regulates our drinking water system, imposed a moratorium on new hookups due to insufficiency of the water supply, a water ban was implemented which restricted nonessential water usage, and a Water System Master Plan study was produced in April 2009.
Issue: These steps addressed the failure of the water distribution system from the wells to individual properties. However, in addition, the District was experiencing deteriorating infrastructure and insufficient capacity to insure continued production of water for an increasing population. The District was also under pressure from DES to upgrade infrastructure and to increase capacity.
Major Water System Components: The current system consists of eight producing wells: Meetinghouse Well at the Gould Pond Road Beach, Hummingbird Well on Hummingbird Lane, Mary Rowe Well off of Mary Rowe Street; plus five wells on Patten Hill which are three wells at the main site and two wells at the end of Patten Hill road. In addition, we have a water storage tank and a main pumphouse facility on Patten Hill, and a treatment facility at the Meetinghouse Wellsite which treats Meetinghouse and Mary Rowe wells. Capacity and flow are now much better through leak detection measures and distribution improvements and meet current standards. However, wells lose production capacity over time, and even though the population levels are stable, a contingency water source plan is being developed.
Infrastructure Improvements: Capacity was added with new Well #11 in 2007. (Note: There are a total of eight wells which are productive). A new Water Storage Tank with a holding capacity of 180,000 gallons was installed on Patten Hill which is still the subject of bond repayments from capital construction financing. A “pumphouse” or main station building was also constructed on Patten Hill in 2012.
Ongoing Infrastructure Improvements: In addition, the District has implemented source protection and security measures by cleanup and enclosure of the wells at Hummingbird Lane and Meetinghouse, and submission of a grant for enclosure and security at Mary Rowe, and the Patten Hill wellsites, in 2014.
Water System Upgrade Plan: Developed by engineers, the April 2009 Master Plan offers a comprehensive but expensive upgrade to the entire system. Due to the shortage of water and partial ban with new service moratorium in 2006-2007, ways to increase flow were a priority and in 2010 this goal was achieved and the DES new connection moratorium lifted, subject to continuing water conservation efforts. Capacity relates to (1) how much water is generated by the wells, (2) how much is lost through leaks in the distribution system, and (3) efforts of homeowners to conserve water as end users.
Leak History: A high degree of leaks were experienced which have been mitigated by several measures so that the flow rate today is better than it has ever been. The largest project was to replace the aging and inadequate sized distribution lines and mains in a large loop around the lake, which was completed in 2013 at a cost of ap $1.8 million. Leak experience has dropped considerably as a result; however, the branch roads still have leakage and need to be addressed in future. Leak repair costs the District ap $20,000 to $30,000 annually. However, complete upgrade of the distribution system all at once is impossible. Therefore, a phase capital improvement plan for future work is being developed. In the meantime, DES requires ongoing flow tests and leak surveys, as well as conservation efforts.
Water Meters: DES will require individual house metering. To date, due to the efforts by the District to upgrade its system, DES has not imposed a deadline. Individual metering will aid greatly in leak detection and correction. However, it will be a very expensive project. It must be done all at once rather than in phases so everyone stays on the same water billing system, the cost will be increased where there are homes which do not have a basement (which are numerous within the District) since a meter vault must then be installed, and the meters will have to conform to current specifications including automatic reading, and the entire billing system will have to revamped. This project can only be done with bond financing through the State Revolving Fund. Although the District has established a reserve fund for meters, it is currently at a level of only ap $50,000 and engineering estimates for this project are in excess of $1 million. The end result will be a billing system with a base charge to cover and recapture capital improvement and financing costs, with any excess being user based.
