Black & Veatch : Water Supply
and Treatment Project
 Sacramento,
CA -- Black & Veatch Corporation announced today completion
of an extensive, multifaceted water supply program for the
South San Joaquin Irrigation District (SSJID) that will
allow for the continued provision of high-quality,
reasonably priced, safe drinking water in an area with
dwindling supplies and growing needs.
In 1995, a declining groundwater
table, fast-paced development and competing demands led the
cities of Manteca, Escalon, Lathrop and Tracy to enter an
agreement with SSJID for the delivery of treated surface
water. Since then, many entities and individuals have
participated in the $136.6 million South County Water Supply
Program, funded through bonds as well as developer and user
fees and completed within budget.
“The coalition has effectively
worked through numerous technical and political obstacles to
design, fund and build the necessary facilities,” said SSJID
General Manager Steve Stroud. “Successful implementation of
this program required tremendous cooperation, and we’re
pleased that we were able to begin delivery of treated
surface water to the participating cities this summer as
planned.”
Conservation measures applied by
the district and its agricultural customers nearly 20 years
ago, along with area urbanization, reduced the need for
irrigation water and left SSJID with water to devote to
other uses. The 1995 agreement between the district and
cities made this surplus water available for local urban use
through facilities to be owned and operated by SSJID. The
district took special steps to meet the needs of farmers and
protect the source water from livestock-related
contamination.
Black & Veatch provided study,
design, membrane procurement and construction management
services for the South County Water Supply Program, which
encompassed watershed protection, raw-water facilities, a
state-of-the-art membrane treatment plant, and nearly 40
miles of buried pipeline and associated pump stations to
convey water from the treatment plant to the cities. Water
Resources Consultants provided program management.
“The technology applied to the
new treatment plant will cost-effectively enable the cities
to meet foreseeable as well as current requirements,” said
Black & Veatch Project Manager Jay Hesby.
The South County Water Supply
Program Water Treatment Plant incorporates innovative
high-rate dissolved air flotation (DAF) and submerged
membrane filtration. The plant will have an initial capacity
of 36 million gallons per day (mgd) and an ultimate capacity
of 60 mgd.
Designed to comply with
anticipated as well as current regulatory requirements for
safe drinking water, the facility will provide high-quality
treated water from a small surface area. Small-footprint
technologies such as submerged membrane filtration and
high-rate DAF offered cost savings in California, where
labor costs associated with cast-in-place concrete and other
construction activities are especially high.
The new system began to deliver
as much as 36 million gallons of water per day to Manteca,
Tracy, and Lathrop early this summer. Construction of
additional facilities, which will increase the volume of
water in the pipeline and extend the line to Escalon when
that city joins the program, is expected to begin between
2010 and 2012.

Solar Bee : Blue-Green Algae
Bloom Control
 Dickinson,
ND -- Since first installed for lake restoration in 2000,
SolarBee solar-powered reservoir circulators have
consistently controlled and prevented blue-green algae
(cyanobacteria) blooms in more than 100 water bodies
throughout North America. By circulating epilimnetic waters,
blue-green algae lose their preferred habitat of stagnant
waters and are consequently out-competed by non-blue-green
algae.
Unlike
the toxic and inedible blue-green algae, zooplankton and
fish will consume diatoms and greens, moving these
beneficial algae up the food chain both materially and
energetically. Typically, water clarity improves as the lake
ecosystem becomes healthier.
The
scientific community has appreciated the ecological
importance of mixing for at least several decades. Previous
research has shown that artificially-induced mixing can
cause species shifts from buoyant cyanobacteria to algal
communities dominated by diatoms and green algae.
More
recently, an experimental study demonstrated that sufficient
water column mixing can shift the competitive balance
between buoyant and sinking phytoplankton in a predictable
manner. These peer-reviewed studies confirm what has been
observed with SolarBee-induced circulation in ponds, lakes
and reservoirs disrupting the blue-green algae habitat
prevents blooms and restores lake ecosystems without having
to control phosphorus or nitrogen inputs.
SolarBees accomplish this goal without destratifying the
whole lake, without bringing up oxygen-depleted bottom
waters, and without any land-based energy requirements.
Furthermore, SolarBees can be scaled to any size water body
- with the largest unit capable of preventing noxious blooms
in lakes up to 45 surface acres, and more units added
proportionally with larger lakes and reservoirs.
In
freshwater lakes and reservoirs, the SolarBee solves
problems of blue-green algae, taste and odor, and release of
iron, manganese, and hydrogen sulfide from bottom sediments.
In stormwater ponds and recreational lakes, the SolarBee can
provide algae control and improve the overall water quality,
enhancing the environmental, aesthetic, and recreational
value.

Wastewater : First Septic Tank
Certified by NSF
 ANN
ARBOR, MI -- If improperly designed or maintained, septic
systems can potentially become a public health hazard by
spreading viruses and pathogenic bacteria that cause
illnesses such as diarrhea, hepatitis A, dysentery and even
typhoid fever.
When
septic systems fail – from lack of maintenance, bad
installation, incorrect sizing or poor soil – drinking water
can become polluted. Untreated wastewater can leak to the
surface where rain washes it into waterways, and it can also
seep into groundwater and pollute wells.
An
independent certification program developed by NSF
International helps protect consumers from faulty septic
tanks. Through this independent program, manufacturers of
septic tanks can make sure that they meet the standards that
help prevent such failure. These program requirements
include standards IAPMO PS-1 and CSA B-66, which contain
design, material and manufacturing requirements for
prefabricated septic tanks as well as US Plumbing Codes and
Canadian requirements.
Ace
Roto-Mold, a division of Den Hartog Industries, well known
for its quality plastic tanks and accessories, recently
became the first manufacturer certified by NSF to meet the
stringent requirements developed for septic tanks.
“Becoming certified by NSF to both IAPMO PS-1 and CSA B-66
standards gives distributors and consumers across the U.S.
and Canada confidence in the design and manufacture of our
tanks,” explained John G. Den Hartog, Den Hartog Industries,
Inc. president. “We appreciate the complete services offered
by NSF as well as the professionalism of their staff. We are
proud to offer Ace Roto-Mold septic tanks that have been
independently certified to meet all NSF, Canadian and
Uniform Plumbing Code requirements.”
For
achieving certification, Ace Roto Mold will be able to bear
the NSF Certification Mark on their tanks. The NSF
Certification Mark is an internationally recognized mark
that inspectors, health officials, manufacturers,
distributors, retailers and consumers look to for an
independent, trusted confirmation that all public health
requirements have been met. To maintain its certification,
Ace Roto-Mold will undergo 5-year testing and annual audits
conducted by NSF.
If
you would like more information about NSF’s mechanical
plumbing certification program, please contact Nasrin
Kashefi at 1-800-NSF-MARK ext. 5743, 734-913-5743 or

Mr. Nelson has a problem with
septic sludge:
We have septic sludge coming
into our plant (we know the source but can't stop it). The
sludge in our primary clarifier is turning even more septic
and is starting to gasify and thin out and it's hard to pump
it out of the primary.
Due to sludge handling
problems, we can't pump an never ending supply out of the
primary to clear it up. We are looking into Alum addition to
try and get it to settle out. Anyone have any other ideas?
P.S. Thanks to all that
responded when I queried about Nitrification earlier this
year, we are successfully doing so this year!!!

Mr. Phillips needs help with sodium hypochlorite
injection:
I have a wastewater plant
converting to sodium hypochlorite disinfection from free
chlorine. The problem is that we have hard water and the
high-pH hypochlorite is causing severe scaling (CaCO3
deposition) immediately at the injector, quickly clogging
it. It's an O&M headache.
Does anyone know of a
particular injector design that solves this problem? I know
that there are specific injectors that solve this problem in
anhydrous ammonia service. I look forward to your
responses.
