Asset Criticality Assessment System

Hi all. Does anybody know what ECM#988741 - Water, Wastewater and Stormwater Mains Criticality and Renewals Prioritisation Process  is?  I can't find this document on the internet. 

Taxonomy

• Condition Assessment

1. TRY GOING TO THE AMERICAN WATER WORKS ASSOCIATION (AWWA)   THEY HAVE A VAST NUMBER OF DOCUMENTS.  FOR SALE, OR AT A DISCOUNTED PRICE FOR MEMBERS.  THAT IS WHERE THE REAL DOCUMENTS ARE.  FORGET THE NET, GO TO THE PROFESSIONAL ORGANIZATIONS. 

2. Bruce;

   I believe it is a document of New Plymouth Council ,New Zealand that offers a guide to evaluate the condition of the network for renewals.

   6.1 Critical assetsWe assess the criticality scores for water supply reticulation mains using the process and scoring system detailed in ECM#988741 - Water, Wastewater and Stormwater Mains Criticality and Renewals Prioritisation Process. These scores are converted into criticality ratings and recorded in the T1 asset inventory to assist us with asset maintenance and renewal planning.We recently commenced a programme to assess and record criticality ratings for plant and equipment assets in the T1 asset inventory. This process is only partially complete and is recorded as an improvement action in the corresponding asset category

3. Had you already searched water documents on EPA.gov website?  I’d start there.

4. Hi Bruce. I suspect ECM means Electronic Content Management and so the reference number is unique to the host system. It is unlikely to be found by the Internet. You will need to find the source system first in order to progress your search unless you are very lucky and someone recognises the reference.

    

   In the UK we have the Sewerage Rehabilitation Manual and now Sewer Risk Management. See the Water Research Centre publications. These are well developed documents used for decades. Water network criticality is also developed and most companies have their own rule sets. Please note criticality is different from 'trunk main'. You can check the Ofwat website for any sewer and water pipeline criticality definitions they apply to the UK water industry for asset management and funding assessment.

   Good luck but expect to have to produce criticality rules that suit given local needs. As a rule for critical sewers these would not normally exceed 25% of the total sewer asset base.

   1. Yes, agree  with Tim that this is the internal reference number for a document maintained in-house. It looks like the document is referenced by the New Plymouth District Council in New Zealand in their most recent Stormwater and Flood Protection Asset Management Plan (see Risk Management section starting on page 23 of PDF):

      https://www.newplymouthnz.com/-/media/NPDC/Documents/Council/Council%20Documents/Plans%20and%20Strategies/Asset%20Management%20Plan/Storm%20and%20Flood%20Protection%20Asset%20Management/Stormwater%20and%20Flood%20Protection%20AMP%20-%20General%20Volume%20pdf.ashx?la=en&hash=D6F0E9A2C92264A9A17AF5EFDEB438D5B3573815

      And ECM refers to their Enterprise Content Management system used to manage documents:  https://www.technologyonecorp.com/about-us/media/news/articles/new-plymouth-district-council-completes-successful-technologyone-ecm-implementation

      You could try contacting New Plymouth directly to see if they can provide you a copy of the document.
