2019 Autumn Conference – ‘AMP7 Future Modelling Challenges’

Wednesday 9th – 10th October 2019 – Conference, Evening Dinner & Workshop

This year the Clean Water Modelling team is heading towards their 8th Annual event and with it we see a return visit to the Best Western Nottingham City hotel.  This vibrant venue, close to all city transport links as well as discounted local parking for those heading straight from the M1 at J26, has undergone a major revamp this year and retains its popularity with delegates staying overnight.

Last years’ successful event was attended by delegates and supporters from across the industry, up and down the country, even Robin Hood returned for a spot of dinner.  Responding to feedback from delegates we have grown our opportunities to attend individual aspects of the event.   As ever we have a rather full 2 days of topical presentations, networking and workshops, not to mention a trip into town.

For those who cannot bear the morning traffic and choose to stay in the hotel on the night prior to the event, or those who have limited time for the whole event, there is the opportunity to join us for an informal pre-conference dinner on the Tuesday 8th October.

To book a place at the pre-conference dinner on Tuesday 8th October, please order your ticket using the link below:

Day 1 (9th October) is a full day of conferencing including delegate notes, tea/coffee and a networking lunch.  This year we will be considering AMP 7 and Future Modelling Challenges.  We are very pleased to have Ian Pemberton from OFWAT heading up our programme of various industry speakers covering all aspects of AMP 7 and the challenges that it presents to the industry as a whole. We continue to open the watery world of conferencing to our industry students and graduates with a limited number of free places and several short papers given by recent graduates, new to the world of conferencing.  The day also encompasses the opportunity to meet our event supporters who are more than willing to divulge information and updates on industry processes and their part in all of it.

The evening networking aspect of the event proves to be a major draw for the event, so this year we will be stepping up a gear and the conference dinner will be heading out onto the town, well okay just two doors along. The city’s Alea Casino will be hosting the conference dinner this year with a three course dinner and a half bottle of wine for those who partake.  We have also arranged for a complimentary private roulette lesson for members of the group who wish to learn how to play.

Day 2 (10th October) sees the popular half day workshop finished off with an excellent lunch for all involved.

The 2019 CwMAG workshop will be focusing on pumps in relation to water distribution networks, an introduction into how pumps are used in clean water distribution networks and how they are modelled in the various leading hydraulic modelling packages. The workshop will cover the more general day to day aspects of modelling pumps and will provide an overview to assist the modelling of pumps.

As part of this workshop Stuart Wallis of SPP Pumps will be giving us all an insight in to how pumps operate from a pump manufactures point of view, covering topics including how a centrifugal and multi stage pumps work, pump curves and how they relate to system curves.

Stuarts section will then be followed up with an overview of how to model typical pump set-ups (Fixed speed and Variable speed) in the main modelling software packages (infoWorks WS Pro, SynerGi and InfoWater). How to generate system curves for pump sizing and analysing system performance. There will be several examples looking at a range of pumping configurations which the presenters will run through. This workshop is designed to be an overview of how pumps operate and what to consider when they are modelled.
