SUMMARY & RECOMMENDATION
The Little Cedar Bayou Wastewater Treatment Plant Solids Handling Improvement Project is
substantially complete. Change Order # I previously adjusted the contract approved by an
additional $4,788 for replacement of electrical conduit previously specified to be reused, and the
addition of an eye wash and safety shower in the dewatering building. During final start-up of
major equipment, it was discovered that the Engineer had specified the wrong pumps and motors
for the polymer system for the new belt filter presses. The COITect equipment was identified and
ordered, and has recently been installed and tested.
The Engineer has prepared Change Order #2 in the amount of$33,053.00 to replace two (2)
previously installed polymer feed pumps, piping and associated controls and electrical
modifications. These changes are necessary to allow the two (2) new belt filter presses to
properly function. The City is contractually bound to pay the Contractor for the new installation.
However, we will be meeting with the Engineer to establish the value of the original installation,
looking to the Engineer to reimburse the City for these costs, as design eITor is at fault. These
costs will be withheld from the Engineer's final payment.
Action Reauired bv Council: Approve ordinance authorizing the City Manager to execute
Change Order No.2 in the amount of $33,053.00.

~I"_''''____~
".-....- ....._-----.
I ~;poke with Rodney (COM) regarding' proposing the following WT Jumps and agreed to
submit the following proposal.
The primary difference in what we are proposing is that each pump wll have 2 heads verses
1. This will require aome fiefd piping modifications.

Desired capacity: 12 gpm /720 gph
Qu :lte capacity: -&:3-sI*R--~~FfI.~&\1+(Qi-~~.-@-4i~
US FiJter Wallace Tiernan has confirmed that printed riterature is
conservative. They will provide documentation ami quote these pumps
with folJowing pump capacitates.
B.38 gpm (12.1 gpm total)' 763.2 gph total @45 pt;1
Chemical: dilute polymer
Dis(:harge psi: 45 pai (pumps win exceed gph @ lower discharge pressures)

No change to electrical I control funotion, The exist. ng drive is a Baldor
115VAC SCR. Our pump can use the same drive @ the existing
115VAC.

....-.....- ........-------
I !lpoke with Rodney (COM) regarding' proposIng the following wr Jumps and agreed to
submit the following proposal.
The primary difference in what we are proposing is that each pump wll have 2 heads verses
1. This will require some field piping mCldifications.
wr Encore Duplex 700
Sp ecs pump per:
Desired capacity; 12 gpm J 720 gph
Qu ~te capacity: ~~l*fl--f~'WFFl.~&f.H.(Qe-~.,.-@Ki~
US Filter Wallace Tieman has confIrmed that prInted literature is
conservative. They will provide documentation anel quote these pumps
with following pump capacifates.
6.38 gpm (12.7 gpm total) 1763.2 gph total @45 p=:i
Cha.mlcal: dilute polymer
Ois(:harge psi: 45 psi (pumps win exceed gph @ lower discharge pressures)
Drive I Electrical: 3/4 Hp DC Motor I SCR control panel (existing)
No Change to electrical J control funotion. The exist. ng drive is a Baldor
115VAC SCR. Our pump can use the same drive @ the existing
115VAC,

Features and Benefits (WT Encore 700 duplex pump)
1. More redundancy; 2 pumps each with 2 heads to acl1ieve maximum federates. Each
head would be driven via a single motor I driVe, Each head would have an
independent manual stroke adjustment
2, Better turn down capability (better control at lower feed rates).

.._,...____--:-
...-.I.._......_----.._~I
I ~lpoke with Rodney (COM) regarding' proposing the following wr Jumps and agreed to
submit the faflowing proposal.
The primary difference in what we are proposing is that each pump wll have 2 heads verses
1. This will require some field piping modifications.
wr Encore Duplex 700
Sp ecs pump per:
Desired capacity: 12 gpm 1720 gph
Qu ~te capacity: -&:3-gl*1'+-f~I~Ff1.Wt&l7+(Qi-p...tetaf.-@-4&"f*;j
US Filter Wallace Tieman has confirmed that printed literature Is
conservative. They will provide documentation ami quote these pumps
with following pump capacitates.
8.38 gpm (12.7 gpm total) 1763.2 gph total @ 45 p~:i
Chl.mlcal: dilute polymer
Dis(:harge psi: 45 psi (pumps win exceed gph @ lower disCharge pressures)
Drive I Electrical: 3/4 Hp DC Motor / SCR control panel (existing)
No change to electrical I control funotion. The exist. ng drive is a Baldor
115VAC SCR. Our pump can Use the same drive a the existing
115VAC,

.-..------:-

I !lpoke with Rodney (COM) regarding' proposing the following wr Jumps and agreed to
submit the for/owing proposar.
The primary difference in what we are proposing is that each pump wll have 2 heads verses
1. This will require some fierd piping modifications.

Desired capacity: 12 gpm /720 gph
Qu :)te capacity: -&:~f*l'+-f~'~Ff-1.tmal) I (QS-~l.@-4e~
US Filter Wallace Tiernan has confirmed that printed literature is
conservative. They will provide documentation anel quote these pumps
wIth following pump capacifates.

6.36 gpm (12.1 gpm total) /783.2 gph total @ 45 pui
ChElmlcal: dilute polymer
Dis(:harge psi: 45 psi (pumps win exceed gph @ lower discharge pressures)

F:'eatures and Benefits CJVT Encore 700 duplex pump)
1. More redundancy: 2 pumps each with 2 heads to achieve maximum federates. Each
head would be driven via a single motor I drive. Each head would have an
independent manual stroke adjustment.
2. Better turn down capability (better control at lower feed rates).

b. 4-1 with pulley drive
c. 10-1 on each pump head via anua! stroke adjustment
3. BOdy:

4. Non-lost motion pumping action (I ss shearing for polyme r and more uniform
discharge.
5. Pump head: PVC

1. More redundancy; 2 pumps each with 2 heads to achieve maximum federates. Each
head would be driven via a slngre motor I drive. Each head wourd have an
independent manual stroke adjustment
2. Better turn down capability (better control at lower feed rates).
