4: Proposed development
Please let us know the type of development you are planning, we need this information to ensure we use the correct
sized supply pipe. Please also let us know the indicative date you need your water supply connecting so your project
runs to plan.
The VAT you will pay on the cost of your water and wastewater services will be dependent on the type or use of the
buildings in your development.
Water reclaim or re-use
Please indicate if a water reclaim or re-use (eg rainwater harvesting) system is to be installed. This is where non-
drinking water or rainwater is to be stored and used for ushing toilets and other uses. Water reclaim systems must
be inspected and signed o as compliant before a connection to the water main can be made, failure to advise us of
installation may result in delays to your connection being made. To ensure that your water reclaim system complies
with the Water Supply (Water Fittings) Regulations 1999, an inspection must be carried out by a Water Regulations
Ocer from United Utilities’ Water Regulations team.
5: Water usage and connection requirements
Please conrm the size of the supply you require and the number of commercial premises being built, and any
landlord supplies required. These are any water connections needed for taps in communal or service areas
ie bin stores.
We also need a complete list of water ttings which you propose to install in the development, this includes any
landlord supply ttings.
If the supply required is for process use we will also need conrmation of your operational hours and peak usage
time. This information is essential as a large demand of water for process use would need to be modelled onto our
water network to check we can supply the water required. It could delay your work if you don’t provide accurate
information with your application.
Please also conrm where you would like your meter located. We need this information so we can send you the
correct specication drawing for the pipework you need to lay within your development, and the meter setup for
each property. This will be sent to you with your quote. Depending on the type of development there are several
options available. For multi-occupancy buildings eg oces, your meters can be installed in a communal area or
within each oce. For single occupancy buildings eg schools, your meter can be installed either in the plant room or
externally at the boundary in a meter chamber. You can also request an energy management system (pulse unit) to
be installed which enables you to read your meter remotely.
We also need full schematic drawings along with internal layout plans of each oor, this is so we can make sure the
water system is designed correctly and won’t cause issues for your development.
5b) Water storage facilities are recommended for multi-occupancy premises or any buildings with more than two
oors. We recommend a minimum of half a day’s storage to allow for any issues that could happen on the water
network ie burst pipes.
If you’re installing water storage and booster tanks, please also advise the size of the tank being installed, the
size of the inlet valve, and the ow rate required into the tank. This will help us to establish if the size of the
water connection you have asked for is suitable for your requirements, this means the ow will be sucient and
there will be no impact on water quality for the building.
5c) Please note, we do not guarantee water supplies for reghting. We advise that you consider water storage for
this purpose. For commercial properties a separate supply for reghting purposes will be required in addition
to your drinking water supply. We also don’t upsize our network for supplies for reghting.
6: Water eciency and sustainable drainage
We oer discounts against the water and wastewater infrastructure charges that are payable when properties
are connected to our networks. These discounts apply to buildings that are built to meet certain criteria for water
eciency and/or drain wastewater away from our existing sewerage networks.
If the buildings in your development are water ecient, you may be able to get a discount on the total cost of the
new water supply for your property. If you t water ecient ttings and appliances which mean the water use in
the house will be 110 litres or less per person, per day, you will be eligible for the discount. To get the discount you
will need to complete the water ttings calculator www.thewatercalculator.org.uk/calculator.asp and include the
report and completion certicate with your application. A copy needs to be provided for each type of building.
Sustainable drainage, such as soakaways and ponds, means surface water isn’t channelled directly into sewers and
watercourses which can help to avoid ooding. Properties built so surface water drainage does not enter the United
Utilities’ public sewer system may be eligible for a discount on the total cost of their wastewater connection.
Further information on infrastructure charges and how our discounts are applied is available at unitedutilities.com/
