Mission clay is closing plant in Pittsburg KS. 2,500 LF of 42-inch diameter pipe available for cost of freight. Conference Recap: Amanda Cauble, WEFTEC, September 2019, Chicago
Presentation: The Importance of Design Criteria Standards For The Construction Of Centralized Wastewater Collection System In The Florida Keys
Background
o Islamorada, Florida Keys, has 6 wastewater systems with seasonal flow
variations and elevated nutrients in marine environment
o Legislation passed in Florida in 2005 that required advanced treatment within 10
years.
o First centralized system (Roevac system) was installed between 2006 and 2010
Minutes by: Nancy McWilliams, Solano Irrigation District Page 3 of 4 Secretary, Nor Cal PUG ***The information disseminated on behalf of industry individuals/organizations via PUG is not necessarily the opinion of PUG, nor
has PUG verified comprehensiveness or validity of the information.***
o Multiple failures due to no design standards, undersized vacuum mains, leaking
connections, and faulty Roevac controllers.
Request for Vendor Proposals
o Village of Islamorada and Program Manager prepared
o Selection Criteria: Cost, quality, responsiveness of support
o AIRVAC was selected as sole supplier in 2009
Interlocal Agreement
o Developed limits for wastewater acceptance at Key largo
o Max strength 375 mg/L; Salinity limit 3 ppt rolling average, I/I max 125% of AADF
o Prohibited certain discharges and/or required pretreatment
Village Wide Minimum Standards
o Developed guidelines, practices, and methods of collection system infrastructure
o Required testing and reporting
o To be updated by Village Utility director as technology changes.
Two-part upgrades
o Improve existing system by replacing valve pits, perform additional testing,
monitor locations with moderate salinity. Prior to upgrades no discharge met 3
ppt limits, following upgrades about 30% of discharge met limit.
o Connect remaining service areas with commercial permits, construction permits,
and place into operation permits. After January 2016, all discharge met salinity
limits.
Update
o As of May 2019, more than 97% of properties have connected to the centralized
system.
o Islamorada has not triggered a salinity surcharge since November 2016, even in
the weeks following Hurricane Irma.
Presentation: “The Sewer Whisperer”: Listen Closely, Your Sewer is Talking to You,” Brogan Quist, Smart Covers. Highlights from the presentation include: The presentation included an overview of the design, installation, and use of Smart Covers.
Company Information o Founded in Escondido 14 years ago by Greg Quist, PhD and David Drake, EE,
two elected water agency officials o 400 customers, morth than 4,000 units in US and Canada, 50% in California .
Product Description o Remote sensor system o Real-time data with communications o Cloud access with analytics o Battery powered o Ultrasonic sensor measures water below sensor, o Pressure sensor measures water depth above sensor o Standard cables: 15 ft and 25 ft. o Reflector on cover is the antenna o IP-68 rated, waterproof, fully potted o Install on any metal or composite lid including pump station hatch.

o Materials: anodized aluminum mounts with stainless steel nuts and bolts
Communications o Measures every 5 minutes, with alarm capability o Data point collected every 10 minutes o Data transmitted every hour o Battery lasts ~2 years o Iridium satellite System, global redundant coverage o Originally used cellular system, but not enough coverage.
Dedicated User Website o Cloud based data o Data Owned by User o Unlimited number of users, amount of storage or time of storage o 2048 bit encryption
Uses o Alarming at important sites or areas that are difficult to reach such as siphons, lift
stations, high frequency cleaning sites, easement, high grease locations, environmentally sensitive areas, or areas subject to flooding.
o At high frequency cleaning locations, using SmartTrend tool can reduce costs by cleaning only when necessary as evidenced by real water level data.
o Provides a n independent and redundant system to back up SCADA o Determine relative I/I in various basins by strategically locating SmartCovers o Notify owner of combined system of overflow allowing decision to store or outfall o Monitor manholes during bypass operations to manage surcharge
Tools Available o SmartTrend: for high cleaning areas, watched flow over time, as flow rises
triggers need for cleaning. Can help reduce unnecessary cleaning. o SmartFLOE: Estimating tool using manning equation for I/I studies, capacity
stdies, and development of SSMP o Rain data is available from NOAA and local gauges and can be overlaid with flow
data o Tide, river and stream data can be overlaid with flow data
Benefits o No confined space entry o Intrusion alarm, help monitor illegal dumping o Multiple source data integration o Can move to various locations as needed o Satellite communications is also a unique more reliable way to communicate vs.
cellular Costs
o Purchase ~$5,000 per cover including purchase, installation and communications o Also rental and lease options. Around $1,000 a month or for a 3 year lease about
$2,500 a year per unit. o Annual fee: $360/year per site
Thank you, Brogan for a great presentation and your contributions to PUG! Next Meeting: The next general meeting is scheduled for Tuesday, March 10, 2020. The topic is PICA Condition Assessment, Kristopher Embry, PICA USA
