Da pool saga part 2.
Our representative Eileen Ohara,has set a small fire under the parks and recreations
Admins feet I hope.
Her recent letter asking when ,where ,bid,no bid ? ,in respose to his leter to her,that
They finnaly have learned the art of pool cleaning??????

Maurice,
Yes you did send a long email Friday but it doesn't answer the question. While it may interest some to know all the steps that need to be taken to clean the pool, all your email pasted below tells me is that it has taken P&R TWO MONTHS to figure out "how to clean the pool?"
The question asked is "when" will the pool be operative. You told me a month ago it would be a couple weeks, but you also said that about the District Park which is still closed. In this detailed explanation (scope of contract) regarding how the clean-up WILL BE conducted, there is no mention of time. Has this gone out to bid or have bids been accepted? When will the work start? How long do you anticipate the contractor will need to complete all of these activities?
The public isn't interested in knowing all you have just learned about how to clean a community sized pool. Further, community pools maintained by the private and nonprofit sectors throughout the area were cleaned up and reopened two months ago.

"We know that you all have been receiving inquiries about the st[atus of opening the Pahoa Pool. We want to get the pool opened as soon as possible, as it is the only community pool available in Pahoa, but we need to make sure that it is absolutely safe for the public and our lifeguards.
We are currently going through the bid process to remove the Volcanic Glass (Pele’s Hair) from the 900,000+ gallon community pool. To give you an idea of what it will take to clean the pool, Roxcie Waltjen (Director of P&R), asked me to send to you all a description of anticipated work (sorry it’s long, but figured best to include everything we need to do):
1. The first step in removal is to pressure wash the entire pool deck within the designated fenced in pool area. This is to include the building walls and any and all sitting, lounging or play toys or play areas within the scope of the pool environment. This wash down will help to ensure Volcanic glass will not be tracked into the water or will affect any of the patrons or pool technicians.
2. The second step is to remove all of the existing sand media in all four filters for the main pool and the one sand media filter for the Keiki pool. The sand is inundated with the Volcanic glass and, as the filters are backwashed, the sand is disturbed giving the glass the opportunity to pass through the sand and return back to the pool. Once the existing media is removed it should be replaced with Filter Ball Blue Sanz media. This type of media increases the filtration from 25 microns to 5 microns.
a. This is a special type of media used in food grade filtration and would be the first run to remove debris to the finest level possible for a Sand style filter. This will capture smaller particles and since the body of the Filter Ball Blue Sanz media consists of a woven polyester, it will greatly increase the ability to retain the sharp glass shards and they will not be able to separate themselves in the backwash scenario.
b. Once this media is installed, we can lower the pump RPM with the use of the external drive by approximately 50% and still attain the flow rate of the system at this time(1900 gpm). By slowing down the pump, we reduce the velocity of the water and allow the media to filter the water at a preferred slower rate. The filters need to be filled to an 80% capacity with the Sanz Media.
3. The third step would be to introduce a flocking agent into the water. By following the flocking procedure, this will allow the smaller particles in the water to coagulate and drop to the floor. These particles can then be vacuumed out with a portable deck based D.E. system. D.E. system filters have the ability to remove down to two-microns in size. This should also be done to the Keiki pool as well.
a. Two times for one week should be sufficient for the Keiki pool.
b. To ensure maximum effectiveness for the main pool, the procedure should be applied at least three times a week for a period of two weeks.
4. After the sand media has been changed and the flocking procedure has been followed, the Filter Ball Blue media should then be removed and replaced with brand new Filter Ball media to ensure all glass that has been vacuumed up and glass that has been captured by normal circulation can be completely removed from the pool environment.
5. Once the new media is in place in all filters, a water sample will then need to be sent to the appropriate lab for analysis to make sure all glass has been removed from the water. Depending on the outcome of the analysis the pool can then be reopened if found to be safe for the public and staff.
Approximate cost: $76,000"
