Although it is clear that global warming is happening and largely driven by human emissions of greenhouse gases, there are uncertainties in projecting when:

  1. the extra water vapour in the atmosphere will contribute to significant rainfall
  2. the ice caps will melt
  3. drought will occur

As a result meaningful policy in the face of Anthropogenic Global Warming (AGW) needs to recognise the uncertainties that exist. Problems in successful climate prediction are created by the non-linear nature of climate response, uncertainties in the emissions trajectory that are followed, and the role of feedbacks in the climate system. As a result, we believe that integrated assessments should be made through the process of risk assessment and disaster prevention(1).

One significant issue is the timescale over which AGW occurs. There are problems with how time is imagined in the future, and the issue of delivering policy options to deal with a problem that might not have policy relevance until the 2080s. As a result, the inability to grasp the concept of time beyond our own lifetimes hinders responses to climate change and requires a closer look at the long-term concept of climate change(2).


Update: Good news 13th Jan. The Environmental Audit Committee’s Water Quality in Rivers Report makes fantastic recommendations, in this context: 54, 310, 311 & 314.

PLEASE HELP: Anyone who is interested in storm overflows, development and flooding to help with the crucial next steps, by writing to their MPs to urge Defra ministers (Eustice/Pow) to accept them.

To avoid flooding DEVELOPERS Need to do 3 things & Govt specifically 1:

1.Not auto connect to sewer to overload it

2.Make sure ALL rain falling on that development’s new drainage, STAYS on that development, not flood others

3. -Called Sustainable Urban Drainage Systems – which must be MAINTAINED

4. Within any 1km of sewer can pull out around 7-8 tonnes of fatberg, 90% of that is plastic based wet wipes. Now is a time to ban them.

for back ground listen to Climate Vision on

or watch BBC Spotlight



Your home sees incoming rain on your roof

And outgoing wastewater

being channelled frequently into a combined sewer

When it rains hard

What falls on one roof

Is the same as what 100 houses let go in wastewater

So, we need to do 2 things

  1. Ask your MP to back up the EAC and get the developer to not auto connect to that overworked sewer
  2. Plus, for every tonne of emissions we emit, we make ourselves more vulnerable. So cut your emissions here



Lord Zac Goldsmith promised a review of legislation Sept 2021, *hopefully* to finally commence Schedule 3 of the FWMA to ensure good quality SuDS in new development. Hopefully resulting in new ‘SuDS Approval Bodies’ (SABs) to (1) check SuDS proposals (2) approve the ‘automatic right to connect’ new drainage to sewers (3) adopt and maintain the SuDS.

*Crucially need to have foresight; councils will need new £ for all these extremely valuable roles*


Today (2/2/17) the Chartered Institution of Water and Environmental Management (CIWEM) launched their report: A Place for SuDS? is launched at the House of Lords. The report is supported by Susdrain, University of Exeter Centre for Water Systems, Landscape Institute, Royal Institute of British Architects (RIBA), The Institution of Environmental Sciences (IES), the Construction Industry Council Champion for Flood Mitigation and Resilience and Cornwall Community Flood Forum.

The report proposes that:

  1. Discharge of surface water to the sewer system should be conditional on the inclusion rst of high-quality SuDS in new developments.
  2. A clear decision must be taken with regard to the adoption and allocation of maintenance responsibilities for SuDS. This should have a clear and established mechanism for raising funds to ensure the continued effective maintenance and eventual replacement of all SuDS they adopt.
  3. New standards are developed aimed at optimising opportunity to achieve amenity, biodiversity and water quality bene ts as well as ood risk reduction. These should reflect the needs of the adopting authority so that they can set out an approval process and adopt with confidence.
  4. The Government should undertake a follow up review of the barriers to retro tting SuDS in existing developments and make proposals on how retro tting might be incentivised.

Also today, Cornwall Community Flood Forum wrote to the Secretary of State and Cornwall’s 6 MPs asking:

Should the Government not me minded at this stage to fully enact Schedule 3 of the F&WMA, we would be keen to learn if it would explore the economics of the well-known barrier (how such responsibilities would be resourced and funded)?

We ask what mechanism evaluates the predicted costs of flooding £2.8bn a year (UK Climate Change Risk Assessment), against the opportunities to fully achieve the benefits of water quantity and quality management, amenity and biodiversity?


The Adaptation Sub-Committee (ASC) of the Committee on Climate Change has been asked by the Government to lead the next UK Climate Change Risk Assessment (CCRA). The summary comprehensively provides startling predictions for the 2080s. By the 2080s, with a 4° warming, with no population growth, it predicts annual costs for flood damages to be £2.8bn.

The UK Climate Change Risk Assessment predicts significant damages costs and stimulates the much needed focus on funding and mitigation (to avoid exacerbating climate change/flooding).


A clear problem is understanding the baseline variability in climate change and climate impacts. For example, it is not possible to assess the magnitude of a 1:300 year flood event when we only have around 50 years of river gauge data on average in the UK. As a result, our long term perspective on climate impacts is poor, and certainly not detailed enough to build a resilient climate policy. More research on climate variability is therefore needed to provide policymakers with the insight required to drive adaptation.

What is the difference between the cost of running a SAB and the local costs for failed SUDs/

And how does that compare with future annual damage costs of predicted at £2.8bn?6

November 3rd 2015 News Bulletin Radio Cornwall (55s)

In January this year, experts told the Environmental Audit Committee3 , that the government were going to be building “20,000 houses a year at risk of flooding, 4000 at significant risk”.

Under the Flood and Water Management Act4 the Sustainable Drainage Systems (SUDs) approval process was going to be closely linked to the planning process. Once commenced, the Act would have required that future construction which has drainage implications will not be able to take place until approval of the drainage system has been given by the SUDs Approving Body. It would have been the role of the newly established SUDs Approving Body (SAB), to approve, inspect, adopt and maintain sustainable drainage systems for new developments exceeding one property.


On the 18th December (2014) Mr Eric Pickles5 (formerly The Secretary of State for Communities and Local Government) from 6 April 2015, declared local planning authorities should consult the relevant lead local flood authority on the management of surface water; satisfy themselves that the proposed minimum standards of operation are appropriate and ensure through the use of planning conditions or planning obligations that there are clear arrangements in place for ongoing maintenance over the lifetime of the development. The sustainable drainage system should be designed to ensure that the maintenance and operation requirements are economically proportionate.

The question is how does the local authority/government expect to pay if the SUDs management company ceases to exist?

Funding of a SUDs Approving Body (SAB) is one of the many issues that might have contributed to the ‘Pickles U-Turn’.


*Read here to find out about today’s activity and responses in the House of Lords. The letter Luci Isaacson MSc has written as Chair of Cornwall Community Flood Forum to the Secretary of State and notes on the debate there today (in the comments).

House of Commons, Environment, Food and Rural Affairs Committee. Post-legislative scrutiny: Flood and Water Management Act 2010. Sixth Report of Session 2016–17

Luci Isaacson was in the House of Lords at this event sharing how Cornwall is affected, especially with its topography, Martyn Alvey from CCFF explained the report, Suds and how they effect Truro to BBC Radio Cornwall. Paul Thomas Fowey Harbour Master also described the need to be resilient on standby to use the Fowey Flood Barrier. “Irene” from Wadebridge enjoys telling Laurence about the flood work there to create a dam and utilise wetland sustainable drainage already in place.

Listen to Luci Isaacson as she responds from the House of Lords event with the next steps, Laura Grant CIWEM talks about the report and developers, Richard Benwell WWT talks about the history of suds and most importantly the rich biodiversity opportunity.


Peter Aldous MP, asked people to write to their MPs to get government onside over key points. Please write and say: “I’m concerned about development and flooding. I think to make development drainage sustainable is not expensive and will not slow down development, all of which this new report addresses. Please could you also ask government to enact the 4 policy proposals on page 32 Thank you”
