Reclaimed Water
Dear Mr. Beck:
Attached are letters of concern from our Landscape Architect and Landscape Contractor regarding
the availability of reclaimed water.
Please note that it is their opinion that without water available during the daylight hours we will be
unable to support the establishment of the new landscaping.
There are alternatives to the use of reclaimed water for this purpose addressed in the attached
letters. Please review these proposals and provide direction to the district.
Regards,

Dear Josh,
With the reclaimed watering schedule allowance only at night, this will affect the fields Seed
germination. New seed will need to watered 3-times daily to achieve germination. If SLI
cannot water during the day, then SLI cannot guarantee germination, and will void there
warranty. Please forward on to the design team for their direction.
Thank you,
Bill Drea

Re: Athletic Field Irrigation
Yelm Junior High School
Yelm, Washington
Dear Stan,
As you know the contractor is working towards completion of Bid Alternate #4, which includes the new football field and
softball field at Ridgeline Middle School. I am concerned that the contractor will be unable to adequately germinate and.
grow in.the grass on these two fields using the reclaimed source for irrigation. Newly germinat`mg grass required irrigation
during daylight hours in order to ensure that the seed bed does not dry out and kill the young grass plants. Typically, the
irrigation runs 4-6 times per day for very short durations, just enough time to wet down the top'/," of soil.
There are two alternatives for irrigation that will allow the contractor to complete their work and provide the owner with a
satisfactory product:
1. ~ Obtain permission, from the City to provide a temporary tie-in to domestic water off a nearby hydrant for operation
of the irrigation during the day, through the end of the fall growing season. This would involve keeping the new
part of the irrigation system completely separated from the existing, so as to ensure no cross connection or
contamination. Once use of the temporary hydrant connection is terminated and disconnected, the new irrigation
could be plumbed back into the existing system and operated on reclaimed water from that point on.
2. Use the reclaimed water for germination of the new grass. This would require obtaining permission from the City
to operate the system during daylight hours in order to keep the ground moist as mentioned above. This option is
further complicated by the spikes we have seen in the pressure of the reclaimed system during the day. This would
likely result in compromised performance of the system, and spotty germination as a result.
Please let me know what we can do to get this issue'resolved. I would be happy to meet with you and the City to discuss in
more detail. The contractor is intending to seed the fields by September 15, 2007, and irrigation water will be needed
through the end of October.
