  • Leading The (Re)Charge How The SFPUC Is Protecting San Francisco Bay Area Groundwater
    naturally recharge groundwater in the San Francisco Bay Area the SFPUC s Regional Groundwater Storage and Recovery Project Project is the first of its kind by the SFPUC to form a partnership for storing water underground during dry years The Project accomplished this by using an In Lieu Conjunctive Use Agreement developed as a regional partnership between the SFPUC and three of its wholesale customers the City of Daly City the City of San Bruno and the California Water Service Company These agencies operate their own groundwater wells in addition to distributing SFPUC surface water to their customers This is the first new water storage that the SFPUC has developed since 1965 and it is one of more than 80 projects that are a part of the SFPUC s 4 8 billion Water System Improvement Program to repair replace and seismically upgrade the Hetch Hetchy Regional Water System The SFPUC began the planning environmental review and design for this Project over 10 years ago Now in construction the Project will provide the SFPUC with dry year storage in San Mateo County and a backup water supply after an emergency The Project s new regional dry year water supply will be able to provide approximately 7 2 MGD from the South Westside Groundwater Basin San Mateo County CA This Project balances the use of groundwater and surface water to increase dry year water supplies In dry years groundwater is pumped from storage the water savings account During years of normal or above average rainfall the SFPUC will provide up to 5 5 MGD of additional surface water to the Project s partner agencies in lieu of their groundwater pumping Over time the reduced pumping will result in the storage of up to 60 500 acre feet or 20 billion gallons of water The SFPUC will only pump groundwater that has been previously stored thus ensuring the sustainability of the project In wet years municipal pumping is decreased and groundwater fills the available aquifer storage space The Project is currently installing up to 16 new groundwater wells and well stations including chemical treatment equipment tanks pumping systems and associated pipelines to extract treat and distribute stored groundwater in dry years It is designed to help meet water demands during a 7 5 year long drought i e recovery of 8 050 acre feet per year thereby stretching the SFPUC s regional water resources This dry year supply will benefit all 2 6 million customers who depend on the SFPUC for all or part of their water supply The construction team is now on the second phase of work which includes the well facility development Each well facility will have various rooms to monitor test and pump water if needed The SFPUC will only pump groundwater that has been previously stored thus ensuring the sustainability of the project Two types of well stations are being built wells housed inside buildings with separate rooms for the well and chemical treatment and wells housed in

  • 3 Game Changers For Water And Wastewater
    reuse we also introduce strategies and technologies for sustainability regulatory compliance funding and labor Bright spots abound in the solutions you ll find throughout the publication very practical and actionable guidance available here but I d like to acknowledge some other bright spots of a different type These are moments of change but unrelated to equipment or processes The following events foreshadow a new normal on the horizon for the water and wastewater industry the arrival date is indeterminate but inevitable And when it comes we may look back and see these moments as turning points When Congress Wised Up On WIFIA The Water Infrastructure Finance and Innovation Act WIFIA was years in the making seeming at times that it would never come to satisfactory fruition Introduced in 2011 the funding initiative for water wastewater capital improvement projects passed through the legislative process in a series of fits and starts In its 2014 incarnation the bill authorized financing of 49 percent of the cost of large plant improvements but the other 51 percent could not be achieved through tax exempt bonds a non starter for many projects However through the tireless efforts of lobbyists including the American Water Works Association AWWA the Water Environment Federation WEF and many others Congress passed a version of the bill in late 2015 that removed the tax exempt bond restrictions on WIFIA thus freeing financing options for sorely needed infrastructure renewal Will it herald an age of new treatment plant construction and pipeline renewal It certainly should When The World Coalesced On Climate Change Action While skepticism name calling and the cherry picking and misrepresentation of data persist the COP21 climate change conference in Paris proved at least one thing World leaders and business magnates responsible for the long term prosperity of nations and multibillion dollar industries believe the threat is real To protect their citizens their businesses and the Earth itself in no specific priority order these leaders are willing to undertake unprecedented investment and accountability For municipalities and their constituents the fear is primarily too much water floods or not enough scarcity while businesses are chiefly concerned with the latter To avoid or mitigate such impacts energy efficiency emissions control and reuse are destined to become the norm across the board by choice or by mandate and many businesses will choose to operate closed loop water management systems COP21 by unifying leaders and introducing reform and pledges on a grand scale may have provided the momentum necessary to truly finally kick start a new era of sustainability When Bill Gates Drank Poop Water You may have seen it on The Tonight Show Starring Jimmy Fallon or learned about it from Forbes CNN Wired NPR or Popular Mechanics When Bill Gates drank water purified from sewage promoting a new technology funded by the Gates Foundation it blew people s minds Of course we in the water industry are familiar with potable water reuse and fully confident in the technologies that make it safe

  • The Age Of Peracetic Acid — A Solution To Increasingly Challenging Regulations
    Peroxyacetic acid or peracetic acid PAA is a chemical gaining a great deal of interest due to its ability to provide bacterial inactivation performance at costs competitive with other mature disinfection technologies PAA is a chemical oxidant that has been applied to the food beverage medical and pharmaceutical industries as a disinfectant for many years and because of its oxidizing power it can address at least some constituents of emerging concern PAA has the chemical formula CH 3 CO 3 H and is produced as an equilibrium solution as shown in Figure 1 Commercial preparation includes reacting acetic acid with hydrogen peroxide in the presence of a catalyst specific grades of PAA are formulated by controlling the concentration and amounts of reagents during the manufacturing process Figure 1 PAA is commercially available in an equilibrium solution The oxidation potential of PAA is higher than other chemicals used in water and wastewater treatment nearly as high as ozone Figure 2 which accounts for its ability to both disinfect and oxidize organic chemicals Because of its reactivity PAA does not persist in the environment and breaks down into acetic acid vinegar and hydrogen peroxide which subsequently decomposes to oxygen and water This is an important consideration in selection of a PAA product for wastewater applications because each formulation introduces a slightly different amount of acetic acid Table 1 which has an associated biological oxygen demand BOD for each mg L of PAA dosed Peracetic acid hydrogen peroxide and acetic acid have low octanol water partition coefficients KOW 0 3 0 4 and 0 68 respectively and low sediment adsorption coefficients so bioaccumulation in aquatic organisms or in sediments is highly unlikely In addition to the facts that PAA does not produce halogenated DBPs and has low aquatic toxicity relative to chlorine its use on site does not require special risk management plans RMPs as required by the EPA when handling certain toxic chemicals Figure 2 Electrochemical oxidation potential EOP for several disinfectants According to the Code of Federal Regulations if the partial pressure of the regulated substance in the mixture solution under handling or storage conditions in any portion of the process is less than 10 millimeters of mercury mm Hg the amount of the substance in the mixture in that portion of the process need not be considered when determining whether more than a threshold quantity is present at a stationary source The commercial products used for wastewater disinfection have low vapor pressures of PAA in the mixture and PAA may be excluded from the RMP facilities are required only to adhere to the general duty clause This is similar to the requirements for the E2 regulations in Canada PAA Applications In Municipal Wastewater PAA has been demonstrated to be an effective wastewater disinfectant over a wide range of effluent qualities requiring low doses of chemical to achieve bacterial inactivation PAA has fast kinetics requiring short contact times for disinfection Capital costs for retrofit of existing chlorine facilities are very low
