The East Wenatchee Water District Commissioners held
a Special Meeting / Open House on August 1, 2016 to discuss water
infrastructure, system reliability, and future water rate schedules.
The following are displays that were present at the meeting.
1. Capital Improvement Program
(Cost of System Improvements & Funding Sources)
2. Decaying Infrastructure Needing Replacement
(77 miles of steel pipe that needs to be replaced)
3. Local Water Rates Comparison
(Rates of 11 Local Water Purveyors Compared)
4. EWWD Long-Term Capital Needs
(Projected Annual Expenditures Adjusted for Inflation)
5. System Main Leaks (2006-2016)
(Major System Infrastructure Failures Repaired)
6. System Service Leaks (2006-2016)
(Secondary System Infrastructure Failures Repaired)
(Current Water Rates & New Water Rates as Suggested by FCS Group)
8. Projected Future Rate Increases
(As Determined and Suggested by FCS Group)
9. Unrepaired Leak Water Loss Chart
(Water Lost Due to System Failure Based on Leak Size)
In 2015, the EWWD purchased 1.303 billion gallons of water.
However, only 1.179 billion gallons of that amount was metered and billed.
That equates to 124 million gallons of water lost due to leaks in a failing infrastructure.
124 million gallons of water (165,775 units of billable excess water)
resulted in a direct water revenue loss of $257,000 for fiscal year 2015.
That does not include revenue lost in expenses incurred to repair the problem.
numbers for 2016 will be even more staggering as the existing system continues
at an even more alarming rate. As you can determine from these numbers, the EWWD
cannot sustain revenue losses of this magnitude without addressing the cause and effect.
The band-aid method of infrastructure maintenance must be converted from repair to replacement.
Pictures of Decaying Infrastructure
Leaks & Corrosion
2" galvanized steel service line with a 1.5" x 1" hole. Pipe is 40 years old.
4" steel distribution main with severe corrosion and decay. Pipe is 37 years old.
8" distribution main cut-away showing corrosion and decay. Pipe is 35 years old.
This picture is worth a thousand words. This is a five foot section of steel distribution
main with 4 patch bands (band-aids). This section of pipe was repaired
4 times in a period of 3 years (2013-2015). This pipe is 40 years old.
As you can see, all of this pipe has seen better days!
This type of pipe (steel) comprises 77 miles of the
195 miles of pipe the EWWD has in the ground.
Some of the pipe is 35 years old... some of it is 60 years old.
Some of it has been failing for years, some is just beginning to fail.
The bottom line is that the steel pipe in our system is failing and will continue to fail.
Ultimately, today's technology and manufacturing processes are capable of creating pipe
(ductal iron, high density polyethylene [HDPE], even concrete) that will last upwards of 100 years.
The condition of the infrastructure within the EWWD is solid and reliable.
Water storage, regional transmission mains and water quality are all up to,
or surpass, recommended standards to deliver a quality and reliable product.
It is time our distribution mains are updated to perform
at the same standard as the rest of our system.
If we continue to simply plug holes rather than replace failing infrastructure, in 20
years, we will find ourselves in a far more dire, and potentially hazardous
predicament than we find ourselves today.
