Singapore NEWater Program

From Toilet To Tap

Paul Rozin argues that we need to overcome our disgust with recycled water. He offers Singapore's NEWater as an example of effective marketing: 

Four treatment plants throughout the country take sewage, filter it through several membranes, and expose it to ultraviolet light to make it safe to drink. Now 30 percent of the country’s total water demand is met using reclaimed (i.e., recycled) sewage. The program’s success was due in part to a dedicated communications team that conducted a massive public education campaign, which included a TV documentary. But Singapore also made the decision to release the cleaned-up wastewater into reservoirs, where it got re-treated along with regular tap water. This extra step was hygienically redundant but psychologically vital in helping Singaporeans accept NEWater as a fact of life.

The above animation was created by primary school students in Singapore.

Horace Dediu's presentation on the history of Amsterdam features the amazing land reclamation map above. Utrecht, which is now inland, used to be a port. And Amsterdam is where the ocean used to be. Haarlem is part of the mainland but looks to be located on what was once a barrier island.

It's a commonplace of economics that they're not making any more land, but this is a powerful reminder that once upon a time it was actually pretty common for technologically advanced societies to build more land. Leaving that era behind us is probably a good idea (imagine the environmental impact review!), but that only makes it all the more important to try to use the land we do have wisely.

Robert Gordon has a working paper out making some not-particularly-persuasive, super-pessimistic, speculative claims about the future of American economic growth that does include, as an aside, this very persuasive observation about consumer surplus:

A thought experiment helps to illustrate the fundamental importance of the inventions of [Industrial Revolution] #2 compared to the subset of [Industrial Revolution] #3 inventions that have occurred since 2002. You are required to make a choice between option A and option B. With option A you are allowed to keep 2002 electronic technology, including your Windows 98 laptop accessing Amazon, and you can keep running water and indoor toilets; but you can’t use anything invented since 2002.

Option B is that you get everything invented in the past decade right up to Facebook, Twitter, and the iPad, but you have to give up running water and indoor toilets. You have to haul the water into your dwelling and carry out the waste. Even at 3am on a rainy night, your only toilet option is a wet and perhaps muddy walk to the outhouse. Which option do you choose?

The answer, obviously, is that indoor plumbing is more important than the combination of everything that's been invented in the past 10 years. Indoor plumbing is a really amazing invention.

But I think it's actually quite important to not mix and match arguments about subjective utility with arguments about GDP and economic growth. I'd gladly give up small kitchen appliances (toasters, microwaves, coffee machines, food processors, and even my beloved immersion blender) rather than Wikipedia. Giving all that stuff up would be annoying, but I could make coffee with a French press, and I'd really hate to lose Wikipedia. But the high subjective value I place on Wikipedia doesn't change the fact that the manufacture, sale, distribution, and marketing of small kitchen appliances is a substantial industry creating tons of jobs and economic activity in a way that Wikipedia doesn't. These are just different things.

Still—take a moment to sit back and try to appreciate the stupendous difference in your quality of life that comes to you courtesy of indoor plumbing.

How Does Horton Infiltration Work in SWMM 5?

How Does Horton Infiltration Work in SWMM 5? by dickinsonre This sketch summarizes what happens in a SWMM 5 Subcatchment for Horton Infiltration during a storm event: 1.       The event starts out with the potential infiltration rate at the maximum infiltration rate but 2.      Decay starts happening right away and the potential infiltration rate starts decreasing until it reaches the minimum infiltration rate (assuming the storm last long enough), 3.      The actual infiltration rate is the minimum of the rainfall rate or the potential infiltration rate, 4.      Using the Huff distributions for rainfall the runoff does not start happening until the rainfall rate exceeds the potential infiltration rate in these models 5.      The runoff ceases after the rainfall rate becomes less than the current potential infiltration rate later in the storm, 6.      The maximum infiltration volume for Horton caps the storm event infiltration at 10 mm in this example, the infiltration will cease when the cumulative infiltration reaches 10 mm. 7.      Horton Iniltration is a five parameter method a.      Maximum infiltration rate in mm/hour b.      Minimum infiltration rate in mm/hour c.       Decay rate for the change from maximum to minimum infiltration rate d.      Regeneration rate for the change from minimum to maximum infiltration rate after the storm event ends and e.      A maximum infiltration volume per storm event in millimeters via Blogger http://www.swmm5.net/2013/08/how-does-horton-infiltration-work-in.html

Benefits of Urban Trees

Via   http://switchboard.nrdc.org/blogs/kbenfield/what_trees_mean_to_communities.html

If you’re interested in the subject of the community benefits of trees, you can get additional information from the websites of the National Arbor Day Foundation and theUS Forest Service.  Among the tidbits I learned on one or the other of those two sites are these:

• The net cooling effect of a young, healthy tree is equivalent to ten room-size air conditioners operating 20 hours a day.
• If you plant a tree today on the west side of your home, in 5 years your energy bills should be 3 percent less. In 15 years the savings will be nearly 12 percent.
• One acre of forest absorbs six tons of carbon dioxide and puts out four tons of oxygen. 
• A number of studies have shown that real estate agents and home buyers assign between 10 and 23 percent of the value of a residence to the trees on the property.
• Surgery patients who could see a grove of deciduous trees recuperated faster and required less pain-killing medicine than matched patients who viewed only brick walls.
• In one study, stands of trees reduced particulates by 9 to 13 percent, and the amount of dust reaching the ground was 27 to 42 percent less under a stand of trees than in an open area.

  

Several years ago, walkability guru Dan Burden wrote a detailed monograph titled 22 Benefits of Urban Street Trees.  Among other things, he calculated that “for a planting cost of $250-600 (includes first 3 years of maintenance) a single street tree returns over $90,000 of direct benefits (not including aesthetic, social and natural) in the lifetime of the tree.”  Burden cites data finding that street trees create slower and more appropriate urban traffic speeds, increase customer traffic to businesses, and obviate increments of costly drainage infrastructure.  In at least one recent study (reported after Burden’s analysis), trees were even found to be associated with reduced crime.

InfoSWMM v11.1 Changes to Date

InfoSWMM v11.1:

Support ArcGIS 10.1.

InfoSWMM or H2OMAP SWMM import: corrected the typos in error messages. (HsHxfSvr.dll, N/A, 6/22/2012)

Improvement: for better hours/minutes listing in Report Manager Report Table for Continuous Simulation with Odd Report Time Step Intervals.  For example, this fix improved the output time display for irregular (in

60 minute sense) output time steps.  Now it displays 00:50, 01:40, etc. more correctly than before (00:49, 01:39, etc). (HsOutPkg.dll, N/A, 6/21/2012)

Improvement or Bug Fix:

Added an IF statement to the RDII Unit Hydrograph Convolution for the  rare instances in which the user sets the time base of the UH to zero by setting either T or K to zero.  The Time Base is T*K in the

convolution integral and zero values are not allowed.  This bug was also forwarded to the EPA for a future SWMM 5.  The convolution uses the value of R and the Time Base to estimate the amount of Infiltration and

Inflow in the Sewer Network.  The short, medium and long term UH’s are estimated at each Wet Hydrology time step to make a smooth hydrograph out of the R, T and  K parameters of the Rainfall Dependent Infiltration

and Infiltration Method. (HsEngPkg64.dll and HsEngPkg.dll, N/A, 6/21/2012)

Improvement: More information for the user when one of nine SWMM 5 warning messages are listed in the HTML Output File. (HsEngPkg64.dll and HsEngPkg.dll, N/A, 6/21/2012)

                These are the nine SWMM 5 Warning Messages

                "WARNING 01: wet weather time step reduced to recording interval for Rain Gage"

                "WARNING 02: maximum depth increased for Node"

                "WARNING 03: negative offset ignored for Link"

                "WARNING 04: minimum elevation drop used for Conduit"

                "WARNING 05: minimum slope used for Conduit"

                "WARNING 06: dry weather time step increased to the wet weather time step"

                "WARNING 07: routing time step reduced to the wet weather time step"

                "WARNING 08: elevation drop exceeds length for Conduit"        

                "WARNING 09: time series interval greater than recording interval for Rain Gage"

                And Here is the Extra Information Now Saved to the HTML Output File in case the user wants to know what is used internally in the engine.  This is especially handy information when moving a SWMM 5 model to

                IWCS or ICM.

Application Framework: introduce the new “Inherited” Facility Set option.  Scenario can now inherit facility selection from its ancestor which possesses a non-inherited facility definition. (HsCadPkgPkg.dll,

HsUI2Pkg.dll, and HsDBBPkg.dll, N/A, 6/21/2012)

                                       New Option in DB Tables for Scenarios

Correction:

The export to the hydqua.inp file when you solve a H2OMAP SWMM model now includes the infiltration data even if the Subcatchment DB Infiltration column is blank after the import of a SWMM 5 file.  The blank row

defaults to the global Infiltration option in Base Simulation Options. (HsDataPkg.dll, N/A, 6/14/2012)

Correction:

Eliminated a duplicate graph of storage infiltration in the Low Impact Development. (HsOutPkg.dll, N/A, 6/14/2012)

Correction:

Implemented a future EPA fix for infiltration loss on a pervious surface if snowmelt is being simulated.   This fix will be part of SWMM 5.0.023. (HsEngPkg64.dll and HsEngPkg.dll, N/A, 6/13/2012)

The error was the double counting the accumulation of snow cover as infiltration in the mass balance table – here is the mass balance without the fix in SWMM 5.0.022

Fixed the problem of Edit Domain Attribute.  It was caused by a table relate issue in DB engine. (HsMapSrv10.dll, N/A, 5/29/2012)

Recompiled to fix a compatibility issue of the validation tool. (HnUtl.dll and HsUtlSrv.dll, N/A, 5/29/2012)

InfoSWMM v11 Update 10:

Changes & Improvements

Fix subcatchment vertex export issue for EPS-SWMM. (H2OSWMM.exe, N/A, 4/18/2012)

Scenario Comparison: Now, the “Hide Unchanged Column(s)” right-click command works correctly. (HsUI2Pkg.dll, N/A, 4/17/2012)

Netview Storage/Wet-Well Output: Fixed an invalid output data field problem. (HsOutPkg.dll, N/A, 4/12/2012)

Scenario Comparison: Fixed Duplicated ID Alias problem. (HsUtilPkg.dll and HsDBBPkg.dll, N/A, 4/11/2012)

Crashed Project Restoration: Now, active scenario ID could be reliably restored

RDII

-----

Check negative GA Hydrograph solution value during export back to InfoSWMM or H2OMAP SWMM. (HsRDIIPkg.dll, N/A, 5/3/2012)

InfoSWMM v11 Update 9:

Changes & Improvements

Simulation Run Report : Added a Scenario data source reference to the title notes section of the RPT file. (HsEngPkg.dll, HsEngPkt64.dll, and HsDataPkg.dll, N/A, 3/15/2012)

Simulation Run Output Data Access: Improved 64-bit access reliability for simulation run output data. (HsEngPkg.dll, HsEngPkg64.dll, and HsOutPkg.dll, N/A, 3/19/2012)

Small Time Base fix for RDII flow to match an upcoming SWMM 5 version (HsEngPkg.dll, HsEngPkt64.dll, and HsDataPkg.dll, N/A, 3/16/2012) :

Description: SWMM 5 makes the time interval used for convoluting the unit hydrographs within a group the smaller of the wet runoff step and the smallest time to peak for the

hydrographs in the group. This works OK when all the hydrographs have rising limb durations no longer than that of the falling limb (i.e., K >= 1.0). For example, the short term

UH has a K value of 0.3, with rising limb time of 42 minutes and falling limb time of  12.6 minutes. As a result, the time interval selection rule stated above was producing too

large a time step for a wet runoff step of 30 minutes causing the convolution to ignore a good portion of the UH.  The rule was modified to compare the wet step to the SMALLER of

the time to peak and time to recede.

Importance of this  for past and future InfoSWMM and H2OMAP SWMM models:

1.            Again, it is a significant and BETTER reason to use the current SWMM 5 engine over v13 of the SWMM 5 engine,

2.            It makes the convolution more robust for a small time base in the RTK method or the Time Base= T*K

3.            It may cause RDII flow differences in this engine if T*K is small over past engines

Add Vertical Roughness to preferences dialog. (HsMapSrv.dll, N/A, 4/4/2012)

InfoSWMM v11 Update 8:

Changes & Improvements

Retain the compatible size for dialog boxes with fixed frame when user changes the screen resolution (DPI) in Windows 7. (HnUtilPkg.dll, N/A, 2/15/2012)

Support upcoming Innovyze application data folder and new product configuration file location. (HxLoader.dll, N/A, 2/15/2012)

Fix:  Improved the Change ID beep interval  for a change to the element ID using the Change ID Command. (HsUtilPkg.dll and HsCadPkg.dll , N/A, 2/4/2012)

Import of a SWMM 5 File with a Duplicate ID now tells you the name and class of object that is duplicated so it can be edited in SWMM 5.(HsDataPkg.dll, N/A, 1/31/2012):

New Feature (HEC_HMS_HYETOGRAPHS.inp, N/A, 2/2/2012): 

How to import the 44 possible SCS Storms from HEC-HMS.  The file HEC_HMS_HYETOGRAPHS.inp is imported into  InfoSWMM using the command Import EPASWMM 5 Data to import just the Raingage and Timeseries data from SWMM5.  The Timeseries data is a copy of the HEC-HMS data for each of the possible SCS Storms for SCS Type1, Type1A,  Type2 and Type3 for 1 minute, 2 minute, 3 minute, 4 minute, 5 minute, 6 minute, 10 minute, 15 minute, 20 minute, 30 minute and 1 hour intervals, respectively.   This is done so that the user of InfoSWMM has the option of using the exact HEC-HMS dimensionless precipitation for every interval and every SCS Storm Type.

New Feature (huff.inp, N/A, 2/2/2012):

InfoSWMM v11 Update 5:

Changes & Improvements

SWMM 5 Export of Dry Weather Flow (HsDataPkg.dll , N/A, 10/25/2011) :

                1.            Many of our users use our DWF Allocator to assign dry weather flow to nodes based on meter data or loading areas

                2.            If they do this improperly then they may get many rows of DWF with zero flows in H2OMAP SWMM

                3.            This does not matter to H2OMAP SWMM as unlimited loads can be assigned to a node but

                4.            This is a problem in the export to SWMM 5 as SWMM 5 has a limitation of one DWF load per node

                5.            Zero DWF loads at a node are now NOT exported to SWMM 5 which makes this more compatible with the internal rules of SWMM 5

                6.            Only Non Zero DWF’s are now Exported

Fixed Dialog Display Issues for Annotation Dialog – moved label frames for overlapping frames.  Annotation is the 3rd Tab in the InfoSWMM Attribute Browser. (HsMapSrv10.dll, N/A, 10/24/2011)

Output Report Manager: A Change to the Output Report Manager to better handle 1 second time steps in the Report Table Section.  This was added to better see the output for Pumps and Force Mains when the Pumps turn on for only a few seconds.  It also allows the user to see the output data and graph a subset of a  long simulation run.  For example, if the user saves at a one second time step for a week this will allow him or her to see all 604800 data points and graph or perform statistics on 5 second  intervals if needed.  It was needed for those simulations in which the Maximum and Report Time Steps are the Same and the time step is small.  If you do save a million or more data points it would behoove you to use the Domain only as the Output Scope in the Run Manager to cut down on graphing time and the Out Folder Size. (HsOutPkg.dll, HsEngPkg.dll, N/A, 7/15/2011)  M

Browser Simulation Report: Added the Outfall Loading Summary to the Browser Simulation Report to be compatible with the SWMM 5.0.022 Status Report; this information has been and is also available as a Tabular Report in the Output Report Manager
