On Thursday, January 12th, an Innovyze User Group meeting was held in Santee, CA hosted by Padre Dam Municipal Water District. Over 30 delegates attended from water and sewer utilities and their engineering consultants from across Southern California attended the meeting.
The goals of the meeting were to learn new tools to enhance their asset management and SCADA approaches, network with other local users, participate in group discussions and knowledge sharing, and submit ideas for potential new software enhancements.
Innovyze wishes to thank all those who were involved in the conference and look forward to future user group sessions.

In InfoWorks ICM 6.5, new subcatchment SUDS/LID structures were added to the software. These are based on the LID controls that are available within SWMM (Storm Water Management Model) 5.1. This allows InfoWorks ICM to model Sustainable Urban Drainage Systems (SUDS) such as permeable pavements, swales and infiltration trenches. The design of these structures can be specified and then the number and type of each SUDS/LID control structure can be specified on a subcatchment by subcatchment basis. The following document explains the implementation within InfoWorks ICM as well as the various SUDS/LID structures that are available within the software.

I’ll use the following example to demonstrate how, with a couple of simple SQL Queries, it is possible to select objects from another table based on their proximity to a current selection of objects.
In the following distribution network there are manholes that are not quite aligned to a fitting. The idea is to find all those that are say a distance of 0.1 meters from fittings. We can see from the image below that a couple of manholes (circled) are much further than 0.1m.
Example Distance Of Manholes.
We begin by selecting the fittings. A way to achieve this is to use an SQL. Continue reading
On Thursday 24th of November, Innovyze’s Collection Systems Modelling User Group was held in Melbourne, Australia. About 50 delegates from around Australia mostly from VIC attended to share knowledge through various case studies, new features and tips and tricks in the software.
On Friday, December 9th, an InfoMaster User Group meeting was held in Oakland, CA hosted by East Bay Municipal Utilities District. Over 50 delegates attended from water and sewer utilities and their engineering consultants from across Northern California.
In this BLOG post I’ll outline a method of converting a value in a text field into a number. So whilst I have what appears to be a number such as 43 or 43.0 or 43.67 in a text field, that is not the case. It is a string.
Numbers in Text Fields Are Strings
Whilst these apparent numbers are strings they cannot be used meaningfully in a mathematical SQL. An example of below, so what we find is that instead of adding the values, the strings concatenate.
Strings Don’t Add They Concatenate
A simple trick is to multiply the numbers by 1, this converts the strings and elevates the data type to a float.
Multiply By ONE
When you right click on your GeoPlan, you may notice that your GIS Layer Control option is grayed out and unavailable.
To fix this problem, first, make sure that your Map Control is not set to ‘None’ (Tools>Options>GeoPlan). You can check this from Tools>Options under the GeoPlan tab.
If it is set to ‘None,’ set it to ArcObjects (if you have a GIS license) or MapXtreme and restart ICM.
If the Map Control was already set to ArcObjects, then you may have opened InfoWorks ICM (64-bit) rather than InfoWorks ICM. Try opening InfoWorks ICM (instead of ICM 64-bit) and see if you can access the GIS Layer Control.
If this still does not resolve the issue, please have a look at the following blog post for some more ideas to troubleshoot this issue: Continue reading
In view of existing and future challenges, such as the results of climate change and the changing manner of water usage, the overriding target of the joint research project KURAS (Concept for urban stormwater management and wastewater systems), sponsored by the German Federal Ministry for Education and Research, was to formulate recommendations for the operation, expansion and adjustment of urban wastewater and stormwater infrastructures to the future. To this end planning methods have been developed in KURAS, in which a consequent evaluation of measures interlink with local requirements and challenges. The basic methods were elaborated within the project for the topics wastewater systems and management of stormwater and applied for Berlin case studies at quarter and catchment area level.
For both topic areas it shows that an integrated, scale overlapping planning of measures for stormwater management and wastewater management can achieve an increased level of usage. The methods developed in KURAS are suitable for supporting such a planning. A standard employment necessitates additional solutions of a technical as well as regulatory nature.

A spatial SQL allows users to make selections or carry out other SQL functionality based on how objects are spatially related to each other. Such as where object as lines ‘cross’ each other. If an object is ‘inside’ another such as a node in a zone, or ‘contains’, where the zone contains incidents say. Finally if an object is at a ‘distance’ from other.
Search Type Criteria
The spatial SQL when executed works on all the ‘Object Type’ specified. However it is possible to run two queries to make a spatial selection query on a selection if you can spare a user number field on the table with the selection.
The two queries in a group should be as follows: Continue reading
In InfoWorks ICM version 7.5 there will be a few changes to the way that the Revitalised Flood Estimation Handbook (ReFH, http://evidence.environment-agency.gov.uk/FCERM/Libraries/FCERM_Project_Documents/FD1913_3259_TRP_pdf.sflb.ashx), initial baseflow (BF0) is calculated. This blog is released prior to the release of 7.5 so that users are aware of the shortcomings of the current approach in which InfoWorks ICM calculates the ReFH initial baseflow.
Currently where ReFH rainfall is applied to multiple subcatchments, all subcatchments will have an initial baseflow calculated based on the area of the catchment used to generate the rainfall (ie, the profile catchment area added in the rainfall generator) unless a value was specified directly on the ‘ReFH Subcatchment tab’. Therefore for subcatchments using the ReFH runoff volume model, the same initial baseflow will be provided regardless of the subcatchment area. Clearly, this can have a significant impact upon the initial baseflow in the subcatchments and is incorrect bahaviour. The correct behaviour would be for the initial baseflow to be scaled by the subcatchment area. This only affects the use of the global initial baseflow and does not affect the values specified in the ‘ReFH Subcatchments’ tab of the rainfall event which should be used in preference to the values on the ‘Globals’ tab.
In 7.5, the ReFH rainfall generator has undergone some changes related to the calculation of initial baseflow for those subcatchments which use the ReFH/ReFH2 runoff model and the ReFH rainfall. These changes are summarised in the following sections. Continue reading
