Default Gray water for irrigation

I have installed a complete irrigation system in my garden, but would like
to use grey water if possible. (Water would be from the bath, shower and
hand basin)

Am I allowed to use it in my own garden?

If so, do I need to do anything to the water to make it suitable for use?

The current system takes water from the roof and stores it in 2 1450 Litre
containers (above ground)
The filtration I have on this is a simple mesh bucket (Used for planting
plants in ponds) followed by a bucket of gravel (The exit holes at the
bottom of the bucket are covered with smaller pond plant pots, so the graven
doesn't escape!)
This then drains into a small water butt, a pump then pumps the water into
one of the 1400 litre containers, this is then connected to a second one at
the bottom, and a high pressure pump then delivers the water to the
irrigation system.

I was thinking of installing a small tank with another pump (with a float
switch) that would also feed into the 1400L containers, but was unsure if
the water needed some kind of treatment to remove soap etc.?

Thanks for any advise, or pointers!

Yes, unless you become subject to a drought order (in which
case the fact that you have used it once already still doesn't
give you the right to use it to water the garden).

If so, do I need to do anything to the water to make it suitable for use?


I don't think so. Make sure you don't wash anything more than
regular soap/shampoo/washing up liquid into it though.

No, but I would avoid storing gray water -- use it ASAP.
Tanks which get lined with soap and fat scum are going
to start smelling.

There may be some plants which don't like it (soap tends to
be alkali). I have used it on my lawn without any problems
in the past. I might hesitate to use it on plants grown for
eating.

So if there was a "hosepipe ban" I couldn't use this water?
Seems a bit daft to me!!

Would using rain water, collected from the roof also be prohibited?

It's just the bathroom, so normal bathroom usage would apply, not things
like Kitchen sink, washing machine or dishwasher

The water containers are made of black plastic, and have lids, so this
shouldn't pose a problem really, I suppose I will only turn on the grey
water pump on when there is limited rainfall (and maybe only when the
storage containers are a certain % full/empty

There may be some plants which don't like it (soap tends to
be alkali).


But would the concentration of soap really pose a problem?
would the average bath/shower/wash contain enough soap to cause any
problems?

I have used it on my lawn without any problems
in the past. I might hesitate to use it on plants grown for

Not a problem now, we don't grow anything for eating (well, apart from some
herbs)

That's very true. Well, not quite true enough. It stinks.

I have no such qualms and I grow vegetables with no man-made fertilisers or
pesticides.

You're also right about not being legally allowed to use it when there's a
hosepipe ban. I use everything I can in such a situation (except tap water
which I rarely use neat anyway). It's up to your own conscience but I prefer
to use waste water of many kinds to grow my food than to put it in the
sewer. I don't use a hosepipe for it. And I don't water flowers or lawn
(don't have grass, the hens ate it all). If we can't eat it it can die as
far as I'm concerned.

I used a hose pipe to siphon bath water during a hose pipe ban a few years
ago. Technically this breached the ban, but Southern Water were content for
me to do this provided they had the right to inspect it. Friend were amused
that I had a visit from one of their officials to see what I did with my
bath water!

All our grey water goes on the garden including the kitchen waste.
Plants thrive on a bit of extra phosphtes from the detergents. That's
the problem with detergents running into watercourses - they produce
algal blooms. Can't use it if there's a hose pipe ban? If that's the
law the law is an ass. We havn't got mains drainage anyway so the
water company can't have it back! Our black water irrigates the land
as well but after its been through a septic tank and a reed bed.

Okay, if they are going be like that, I am not actually using a hosepipe,
all the irrigation system is made up of...

25mm MDPE water pipe "Ring Main" under the ground, around the garden (Like
they use to deliver mains water)
13mm "Delivery pipe"
4.6mm "Supply Pipe"

The lawn is watered with the pop up sprinklers, the beds are watered with
little sprinklers and the pots are watered with drippers

Would this be prohibited in a "hosepipe" ban?
In which case, should I fill my water containers with mains water, as long
as it does not go through a hosepipe?

I can see that they might have a case if you deliberately left your
bath tap running and then watered your garden with the 'grey water'
during a drought, but come on, there has got to be some common sense
left in the world.

Yes, but due to a *severe* shortage, a ban on 'common sense delivery
by hosepipe' has been in effect for central and local government in
the UK for most of the last couple of hundred years g

And Sparks, sadly the ban also applies to lawn sprinklers I believe.


Bugger, how about small flower bed sprayers (Not sprinlkers :-) and drippers
like these
http://www.grovelands.com/acatalog/G..._watering.html


would be dubious of using grey water in a sprinkler system anyway,
depending on the hardness of your water, soap scum can build up and
clog the heads (although your filtering system may well take care of
that).


We live in a reasonably hard water area, however we do have a water
softener, so the water that is used in the bathroom is very soft.

Contacting the water company anonymously might be an option,
see what they say with regards to the issue.


I have just written an email to someone at the environment agency, as their
website has information about harvesting rainwater, hopefully they can help!

I think they're likely your best bet, the only information on exactly
what a hosepipe and sprinkler ban actually applies to that I can find,
is very very vague in the best tradition of UK legislation and
regulations:-)

Hum, I wonder if this might cause a problem with gradual

(assuming your softener is an ion exchange type)?

Yes it is (I think! - I put salt in it!)

that salt ends up in your grey water, and sodium chloride has the same
effect as sodium chlorate. Vey dilute so it takes years to have an
efect, but yes it does.

Thats one of the probs with grey water, you have to be fussy about what
you let get in the water.

There are many plants that will still grow ok, but not all. If you
wanted a mint pond or reed bed I believe you could use it for those.
And many other things.

The rules can be silly.

My parents used to have a swimming pool in the back garden. This was
during the 1977(?) drought.

Under the rules we were allowed to use hundreds of gallons of water in
order to keep the pool topped up, but the neighbours couldn't use a
garden sprinkler.

The water system failed on several occasions. We used to leave the
back gate open and neighbours would come around with a bucket and take
water from the swimming pool.

Siphoning the bath meant it was more convenient to leave the hose pipe
outside on display for extended periods of time. I contacted them to avoid
any subsequent misunderstandings.

That's a good idea.

I don't know anything about SW but Yorkshire Water is very supportive of the
environment and I'm willing to be guided by them. I certainly don't feel the
need to use any kind of water on decorative parts of the garden (such as
they are) but I do carry much waste water to the vegetables. We pay for it,
we make the most of it.

Hosepipe ban is simply a convenient handle for the media. All forms of
automatic watering systems are also included. Usually you can still use grey
water, but only by using it to fill a watering can etc.

Including stored rainwater supplied through a trickle irrigation system
on a timer? I wouldn't be surprised - this is sufficiently stupid to
make it onto the statute books - but do you have a reference for the
official text.

Doesn't apply to rainwater. Does apply to water supplied
to you and water you extract from a well/borehole/stream,
even if you already used it once for some other purpose
(and hence it's now regarded as gray).

Can't point you to a statute, but this is what a note from
Three Valleys Water said in the late 1980's when we had a
hosepipe ban for a few years in a row (and they had to keep
refunding my hosepipe license fee).

Plugging the bathroom outflow into the garden's inflow.

All you need to do it take a section out of the downspout before it
joins the main drain. If this happens on the outside wall it is a simple
job that won't cost more than a few quid in plastic pipe. (Water butts
are a lot more of course.)

It might be worth thinking about if we are in for a few of these
summers. If we are at the start of a bad dought cycle and it doesn't hit
the peak of the other end of spectrum for another 15 years, that
indicates about 7 years or so of dry summers. It would be an investment
if there is a re-run of the late 1970's. (IIRC.)

From two full containers you'd get:

2900 liter =

637.9108201 gallon [UK] =

0.0282128 acre-inch (or if the garden is about 1/10th of an acre you
will have enough to give it all 1/4 inch.)

That is actually plenty for a week or so.

In my lifetime (from 1950) we have had dry summers, wet summers and
summers that were a bit of both.

I can';t say that I have seen any discernible pattern, although the
winters seem warmer than they were - far less frost about.

And as I write, the lightning is flashing over teh horizon. End of THAT
dry spell for a day or so I suspect.
