Yes, it appears to be a white-flowered water lily, but I'm not sure enough info has been presented to really be sure it's the species Nymphaea alba (as opposed to a number of other white-flowered species/cultivars), although perhaps you have other info that confirms it. Nymphaea alba is said to have leaf margins tinged red, orbicular leaves (these don't look exactly orbicular but it's hard to judge with them standing out of the water) with V-shaped sinuses (could be but also much easier to see when leaves are floating).
It does look like a hardy water lily (and Nymphaea alba is a hardy water lily).
Odd how all the leaves are standing out of the water, as though it was confined in a very small pond, though clearly it's not.
Good heavens, I would hope no one would be offended by anything said here! :-)
Since it's supposed to be a plant ID forum, I'm just providing some of the characteristics of Nymphaea alba for comparison.

The two common wild water lilies are easily identified when in flower: Nymphaea alba bears white flowers in July and August and has rounded leaves, while Nuphar lutea, from June to August, bears yellow flowers which are much smaller, and has oval leaves. Both have massive underground stems or rhizomes by which they are anchored to the bottom of the lakes, ponds or slow-moving rivers in which they grow. Leaves and flowers grow up from the bottom and float on the surface, because their stems are spongy and full of air spaces. Although the leaves are large, they do not shut out enough sunlight to harm other pond life. At night the petals collapse and the flower may sink below the surface of the water to emerge again next morning. The rooting stems are sometimes eaten in northern Europe, and in the past were used as a cure for baldness.http://www.geograph.org.uk/reuse.php?id=1408002
hi vngarden, I've enjoyed your participation, I like to play 'guess and check' and learn on this forum, I try not to guess unless I feel pretty confident, since I am "uneducated" as well. I can't imagine anyone has been annoyed at your contributions .
The single photo above of the white water lily which is with the article Woodfry's Farm is a copyright to Miss Steel and not to myself RosinaBloom.
My computer skills are perhaps not as good as my photography! Hope this has not caused a problem.
You have been a treasure in helping me ID so many of my plants in the last couple of days. For this I am truly grateful.
By the sounds of it, like you I am more of a hobby photographer - but we're all willing to learn.
I am using a Finepix HS20EXR at the moment - the macro lens is part of the camera, so I don't have to get too clever! The latest version out is a little lighter, and does not have AA batteries to recharge up. (A friend has just returned from the States with the next version up).

Yes, they'd be very easily distinguished if the plants were in the wild and observed in a place where they are native; given that is not the case (the plant appears to be in cultivation where those two species are not native), it opens up the possibility that it is some other white-flowered, probably hardy water lily. (Actually, Nuphar lutea would be very easily distinguished in any case.)
It may be Nymphaea alba. Could you get close-up photos of the flowers and undersides of the leaves with a small ruler in the photo for scale?
Without being able to make out some details, it could also be Nymphaea odorata, or various hybrids, e.g. 'Marliaceae Albida', 'White Sultan', etc..
