Request for Quotes # PW-1904-{0967, are by this reference made a
part hereof.
SPECIFICATIONS / SCOPE OF WORK
All construction work shall be done in accordance with the Technical
Specificafions to the ISPWC (and any Addendums).
a No work may proceed without written Notice to Proceed from the City. Work is
contingent upon the successfultesting at the City's Wastewater Facility. Once
the facility receives confirmation of testing acceptance, there is a four (4) week
waiting period for the City's Operations Department to prepare the Digester for
the cleaning process.
1.01 SUIIMARY
A. Section lncludes: Draining, cleaning, and dewatering provisions for an anaerobic
digester. ln general, the contractor will be responsible for pumping out and cleaning the
digester, dewatering the digester solids so they are suitable for disposal at the landfill,
and directing the resulting dewatering liquid into the treatment facility drain or holding
tank system.
1.02 SYSTEM DESCRIPTION
A. DesignRequirements:
1 . The City of Meridian intends to have a contractor drain, clean, and dewater solids
from an existing anaerobic digester at the municipal WRRF. Digester criteria
include:1) Diameter - 70 feet2) Side Water Depth - 26 feet
3) Volume - approximately 800,000 gallons
4) Estimated Solids Concentration - 3olo
5) Estimated Solids Content - 200,150 pounds
DIGESTER 5 CLEANING Page 11 of 16
Project 10967
Meridian City Council Meeting Agenda May 7, 2019 – Page 394 of 537
6) Fixed Cover Digester2. There are two available drain connections on the digester. One drain is located on
the rectangular access hatch approximately 12 feet above the bottom of the
digester cone floor. The access hatch connection consists of a 6-inch flanged
isolation valve. The 6-inch drain connection could be used to drain the liquid level
down to the access hatch so that the hatch could be removed and the remainder
of the digester could be drained through an existing &inch line constructed within
the digester, by a suction pump, vactor truck, or other appropriate means.3. The second potentialdrain connection is located on the &inch digesterdischarge
piping which runs from the bottom of each digester cone into the digester building.
A portion of the piping would need to be removed inside the building by the
contractor and a new connection made to allow draining of the digester contents.
The 8-inch drain connection could potentially be used to drain the majority of the
liquid contained wtthin the digester.4. The two drain locations are included within the attached Figures.5. The goal is to drain as much liquid sludge out of the digester as possible using
one or both of the drain connections. The major concern is the potential for grit,
rags, hair and other solid waste plugging these lines during digester dewatering
efforts. There is a crust approximately 2-3 feet thick located towards the top of the
digester that may be difficult to break up and remove. Additionally, there is a
substantial amount of sand, grit, rags and other solid waste accumulated along
the bottom of the digester that could impact the ability to pump liquid solids out of
the digester. lf the liquid level can be drawn down far enough to remove the
access hatch, atthat point mechanical or manual methods can be used to remove
the remaining material. Manual removal of hair, rags, grit and other solid waste
accumulated within the digester is likely. Non-potable water is available for use by
the contractor to assist with fluidizing material within the digester for removal.6. As the digester is being drained, the digester contents will be pumped to a
dewatering system. The contractorwill be responsibleforfumishing and operating
the pumping system, including electrical power if necessary. The City may supply
welded 6-inch HDPE pipe which can be used by the contractor for conveying
contents from the digester to the dewatering system. The contractor will fumish
and operate the polymer system necessary for dewatering and supplying the
polymer chemical. The contraclor is responsible for furnishing and operating the
dewatering equipment, including electrical power if necessary.7. Liquid resulting from the contractor's dewatering process must be diverted back
into the treatment facility drain system or into a storage tank. The contractor is
responsible for diverting the liquid into the drain or storage tank. The location of
discharge must be approved by City staff.
B. PerformanceRequirements:1. To allow disposal at the landfill, liquid and all materials pumped or removed from
the digester must be dewatered to pass a paint filter test. The dewatering method
will be up to the contractor. lt is the contracto/s responsibility to dewater the
digester contents without aid of other bulky materials so they are suitable for
landfill disposal and capture solids to not cause operational issues at the WRRF.
The contractor will be responsible for conducting polymer jar testing prior to
dewatering activities to determine the type and amount of polymer necessary to
adequately dewater the solids using their proposed dewatering method.
The dewatering approach involves setting up dewatering equipment within or
around the northeast sludge drying bed. This is the only drying bed available. As

the solids are being dewatered, liquid resulting ftom dewatering will be sent into
the plant drain or into one of the centrate holding tanks.4. The contractor will be responsible for operating the dewatering equipment and
adhering to the performance criteria (i.e. maximum allowable centrate TSS).5. Dewatered solids produced by the contractor will be transported by the contractor
to a designated pile, separate from the standard plant operations pile, for paint
filter testing. Upon passing the required test, the City will combine the separated
pile with the existing biosolids storage pad. The City will be responsible for loading
the dewatered solids from the storage pad into transport trucks for removal and
disposal.6. The maximum allowable total suspended solids ffSS) in the liquid return is 500
mg/L.The Citywillconduct random sampling and laboratorytesting to ensurethe
TSS limit is met. lf the TSS limit is exceeded, the contractor must shut down and
make the necessary adjustments to adhere to the TSS limit.7. The dewatered solids must pass a paint filter test. The City will conduct random
sampling and laboratory testing to ensure the dewatered solids pass the paint
filter test. lf the solids do not pass the paint filter test, the contractor must shut
down and make the necessary adjustments to adhere to the dewatering
requirements.8. The contractorwill maintain a clean working environment. Any sludge, biosolids,
polymer, dewatering liquid or other materialthat is spilled during the contracto/s
maintenance activities will be promptly cleaned. ln the case of a larger spill of
sewer sludge or dewatering liquid caused by contractor negligence, the contractor
may be held liable for all costs associated with the cleanup, regulatory reporting,
and fines imposed by any regulatory agency. The contractor must immediately
notify proper City staff if a spill or overflow (SSO) occurs.
