Why are there watermarks over the top of the map area I am trying to view?

If you are trying to view an OS Map, the watermarks will appear over the map (this is so we conform with the terms of our Ordnance Survey licence). The watermarks are transparent enough to allow you to locate and select the area you require. Once you have ordered the OS Map, you will receive your selected area without the watermarks.

If you are trying to view a utility’s Asset Plans, the watermarks will show in the following instances:

- If you are not authorised to get free (statutory) access to Asset Plans, the watermarks will be visible until your order has been processed, at which point you will receive your selected plan without the watermarks.

- If you have requested statutory access but your access has not yet been authorised by the relevant utility. However, you are still able to purchase Asset Plans and OS Maps via digdat Utilities until you receive confirmation your access has been authorised.

- When the relevant utility has no assets within the area selected.

- When the selected area falls outside of the statutory viewing boundary that your account has been authorised to access.

Back to top

When I try to print a specific area why does it display the message ‘There are no assets within this map area’?

This means there are no asset records for the utility datasets you have chosen within the area you are printing. You should zoom out to the maximum extent allowed to confirm there are no assets in the surrounding area. If assets come into view, a map will be displayed.

Do you have a user guide?

How are the Ordnance Survey map prices calculated?

Pricing for Ordnance Survey maps are based on the amount of information provided within the selected area and therefore the price will vary according to the size and density. All costs are confirmed when you proceed to the checkout.

How do I know if assets are present prior to purchasing an Asset Plan?

If the area searched does not enclose any utility asset records, the service will not charge you for this request. You will still be able to print off a watermarked plan for your records providing evidence that in that search location, on that search date, there were no asset records present for that specific utility.

Anglian Water Clean Water Data

Am I allowed to build over or close to public water mains?

Unlike sewers, where permission to build over or close to mains may be given, Anglian Water DO NOT permit any building over of water mains. Water mains operate at pressure, hence they have the potential to cause considerable damage for which Anglian Water could not be held liable.

Back to top

I am installing a new water service and need to know how deep the trench should be for water service pipes?

There is a minimum and maximum depth at which service pipes should be laid. Minimum depth is 750mm and the maximum depth is 1350mm. If you wish to install a service pipe either deeper or shallower than these depths they must notify Anglian Water for permission. Important note: The water service pipe must be a minimum of 350mm away from any gas supply.

Back to top

Can I build a new extension over an existing mains water supply pipe?

No. The existing mains water supply pipe will have to be either re-routed around the new extension or it will have to be installed in a duct so that it can be removed for maintenance or repair.

Anglian Water Recycled Water Data

I am planning to carry out building works and there is a sewer crossing my land. What should I do?

When you apply for Building Regulations approval, Building Control should consult Anglian Water regarding any proposals to carry out work within 3 metres of the public sewer. We do, however, strongly recommend that you contact Anglian Water before this time, so that we can discuss and agree what works are acceptable within the vicinity of the public sewer. Please be aware that planning consent does not mean you have been granted approval to build over or within 3 metres of a public sewer.

If I have a query regarding sewer adoptions, buildovers and other sewer related matters in the Anglian Water region, who do I contact?

Please visit http://www.anglianwater.co.uk/developers/ for further details regarding these matters.

What is the difference between 'Wastewater' and 'Recycled Water'?

'Wastewater' and 'Recycled Water' are two different terms to describe the same thing. Anglian Water has recently made a small but important change to the use of the term 'wastewater'. This will now be referred to as ‘used water’ or 'recycled water' – the change is intended to lead the way in changing perceptions about water and how it is used. No water is ‘waste’ water, it’s a precious resource that we borrow, use, clean and carefully recycle to use again and again.

For the purposes of digdat we have kept the wording consistent because other water companies around the country are still using the term 'wastewater' so you will still see reference to it. If you visit the Anglian Water website the term 'Recycled Water' will be used instead.
