If reservoirs alone or tackling leakage won't save us from water scarcity & with flood risk on the rise, we need an overarching National Rainwater Strategy to inform water management in developments.
Rainwater reuse & SuDS.
The benefits would be big. More: www.ewsc.org.uk/project-repo...
Great piece by @itvnews.bsky.social on why the UK still won't have enough water despite building new reservoirs, and some of the other approaches that could unlock water resilient housing and wider economic growth in water scarce areas. @ciwem.bsky.social

On every level allowing special dispensation for Thames would be a disaster + set a horrendous precedent.
- Other companies- why bother to comply?
- Govt elected on a mandate to clean up rivers/ seas seen as utter frauds
- Regulators a total laughing stock

That hosepipe bans are one of the first drought measures implemented shows how effective water efficiency is. Home visits are an important part of longer-term programmes. In the SE, 1/2 of new water needs are to leave more in the environment @adamvaughan.bsky.social. www.thetimes.com/uk/environme...

2) Govt yet again blames inheritance of a "crumbling water system" from the Tories.
That may be, but it needs to stop blaming and get acting. Water efficiency is highly effective in drought yet govt's done nothing to progress measures set up by last gov.

1) The National Drought Group meet on Wednesday. Water companies likely to activate drought plans. Early action is important to mitigate the impacts seen on nature and agriculture and preserve public water supplies in case of a hot dry summer. www.theguardian.com/environment/...

It's certainly dry so far this year compared to many previous drought years.
We'll likely need 2012-esque wet early summer to pull back from the brink.

Itβs utter lunacy.
Nature & green access aside, how can on one hand govt confirm raised ambition for heat pumps & solar then on the other light a fire under the urban heat island effect?
The same week its statutory climate advisers warn its progress on climate adaptation is beyond uselessβ¦
Wales has had 30% less rainfall than this point in 2022. In extreme dry conditions, areas with surface water reservoir storage feel the pinch most quickly.
Welsh water starting to encourage people to use less. Expect this kind of messaging to spread.

Govt has some oven-ready wins to address failings identified in yesterday's @thecccuk.bsky.social climate progress report.
In fact the last Labour government set them up.
Whilst Labour loves to point to past Tory water failures, it also needs to get on and act.
www.ciwem.org/news/governm...
3) New reservoirs won't come on stream for many years.
Government really needs to urgently bring forward water efficiency measures like product labelling and building regulations alongside new infrastructure and leakage reduction.
These things are pretty much oven-ready.
2) In 2022 it was only really July that saw rainfall anomalies approaching as outrageously extreme as this March's. The heat then led to big spikes in demand which exacerbated things. This April's is likely to be pretty dry too.

1) This spring feels not dissimilar to 2022 when we last had drought and heatwaves. Except it's arguably drier. Whether we see drought measures later in the year depends on the next couple of months.
inews.co.uk/news/summer-...
4) It must be hoped that the Water Commission has the wisdom to recognise these climate-water sector nexus issues & that Govt is waiting for this endorsement to move. @richardbenwell.bsky.social.
Measures like Managing Rainwater Where it Falls could be a great start.

3) The Code for Sustainable Homes was a Labour initiative. This govt is seemingly indifferent to its impressive water efficiency drivers.
Whatever the Tory inheritance this Govt should now be moving forward these common sense measures. But seemingly short term growth trumps all.
2) The Climate Change Act 2008 was a Labour Act orchestrated by Ed Miliband. Yet govt is seemingly indifferent to its adaptation side. The Flood & Water Management Act 2010 was Labour Act. Govt is seemingly indifferent to its Schedule 3 on drainage.

@seabrookclimate.bsky.social. Govt is keen to blame state of flood defences, water infrastructure etc on Tories. But it is feet-dragging/ backsliding on key flood/ drought resilience policies Tories were planning. news.sky.com/story/govern...
2) Sustainable drainage is one part of that resilience jigsaw. Recognised back in 2007 & beyond, legislated by
@teamlabouruk.bsky.social in 2010 but never implemented. Why @tobyperkinsmp.bsky.social is govt seemingly backsliding on #SuDS? Your committee might wish to probe.

Ministers know what needs to be done but housebuilding seemingly trumps all else - & communities suffer.

It's hard to get your head around the scale of the environmental vandalism the Labour government is hoping to unleash. The Planning and Infrastructure Bill is up there with Trump's executive orders. And the reason is the same: corporate power.

(8/8) Finally, @emmahardymp.bsky.social, A National Rainwater Management Strategy π¦οΈβοΈποΈπ£οΈπβ°οΈ
That sets out how we manage rain where it falls, harvesting it as a precious resource. In homes, on farms
AND stops it mobilising sewage, farm waste and toxic highway runoff into our rivers, lakes and seas.
(7/8) Enhance local/ regional democracy around water priorities, giving mayors a role in overseeing/ enabling regional priority programmes with wider stakeholders & greater ability to direct funding. Beef up catchment partnerships as on-the-ground enablers.
www.gov.uk/government/p...
(6/8) AND...
- Review βwholesome waterβ regulations to enable harvested rainwater to be used for non-potable purposes such as toilet flushing (Section 68 of the Water Industry Act 1991 and Regulation 4 of the Water Supply (Water Quality) Regulations 2016).
(5/8) That'll deliver only about 1/3 of what we need. The rest will need to come from leakage + water efficiency. Govt must step up on policy:
- Mandatory water efficiency labelling on goods/ fittings
- Building regulations targeting 80 litres/ person/ day equivalent
www.gov.uk/government/n...
(4/8) Major water infrastructure needed:
- 9 new reservoirs (+1 expansion)
- 9 desalination plants
- 8 major water recycling schemes
- 5 major water transfer schemes
(3/8) Alongside cleaner water we need enough water.
Facing a near-5 billion litre/day shortage by 2050, in some parts of the country half of this is to restore sustainable river flows (environmental destination).
Low flows exacerbate the impacts of pollution.
(2/8) Then, other sources of pollution:
- Agricultural runoff through regulation + well-targeted support,
- Toxic highway runoff tackled through far more treatment wetlands and other devices - see www.ciwem.org/policy-repor...
