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, we DO NOT permit any build 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.
Do I need permission to connect to the public water supply system and how can I find out if the water mains have sufficient capacity to service my development?
Capacity checks are undertaken upon application – further details are available on our web site. Connections to existing water supply mains can only be undertaken by Anglian Water.
Can I lay my water main in the same trench as other utilities such as gas and electric?
Provided adequate clearance is provided between the water main and other pipelines, it is acceptable for the water supply to be laid in a trench common with other utilities.
Why do you make a sewerage infrastructure charge when I apply for and connect to a public water supply?
Infrastructure charges relevant to water supply will be raised when any premises are connected to our water mains for the first time. For the majority of new developments (including conversions) and existing properties which become connected, the standard amounts will be payable in respect of each individual unit. The water infrastructure charge is payable when the premises are connected to the public water supply.
Please note: The sewerage infrastructure charge is payable if the premises drain to the public sewer (either directly or indirectly).
Once I have accepted an offer of term for a new water main connection, paid all relevant monies and completed any necessary agreements, whom should I contact to programme the work in?
Depending on which county your development site is located within, you should contact the appropriate office:
Lincoln: 01522 341718
Milton Keynes: 01908 453118
Norwich: 01603 247117
What is a local offsite main?
A local offsite mains refers to mains reinforcement required to accommodate additional demand in the local infrastructure as a result of a development being carried out. Unlike a strategic contribution this category of main will normally be associated to a particular development and its affect on the local network as opposed to a regional growth requirement.
These mains will be charged as part of the scheme costs, put through the Relevant Deficit/Discounted Aggregate Deficit calculations and form part of any reconciliation processes
What is Relevant Deficit (RD)?
The relevant deficit is the amount by which the revenue received from new customers, connected to the new infrastructure, is exceeded by the annual borrowing costs of financing that infrastructure, in any specific year across a 12 year period.
In this option an initial estimate of scheme costs is provided and on an annual basis the deficit is calculated by comparing the actual income from newly occupied customers against the capital financing cost (adjusted as necessary in line with actual scheme costs).
The Developer may pay the projected relevant deficit upfront whereby an annual statement will be provided showing actual deficit deductions or provide a bond to cover the 12-year period whereby invoices will be issued for the actual deficit annually.
What is Discounted Aggregate Deficit (DADS)?
The discounted aggregate deficit (DAD) is the sum of the projected relevant deficits for each of the twelve years discounted back to net present value.
In this option an initial estimate of the cost of the scheme is provided and income from new occupations is calculated from the proposed build rate.
The expected DAD contribution can be paid in advance as a commuted sum or a bond can be provided to guarantee payment of the DAD after the requisition has been completed. The final amount paid under DAD will be adjusted in line with actual scheme costs.
What happens in the reconciliation process in respect to my DADS deposit?
Within twelve months of completion of the mainlaying covered by your requisition, Anglian Water will undertake a reconciliation of the costs incurred in laying the mains.
In practice this means that Anglian Water will re-run the DADS calculation using actual costs, as opposed to projected costs, and actual build rates, as far as is practical with the remainder utilising the supplied build rate, to re-calculate the DADS contribution due. We will then settle the balance with the Developer.
What is a strategic contribution?
Anglian Water carries out improvement works involving large strategic water mains in order to accommodate growth with our region. Part of the cost incurred is to be recovered from the developments within the affected area which will benefit from the additional water being made available.
This cost is calculated on a litre-per-second rate and apportioned to developments based on their litre-per-second demand. For example if the rate is £14,000 per-litre-per-second and the development needed 0.1 litres-per-second then the contribution by the Developer would be £1,400.00.
What is Self Lay?
Self lay is an option under which the onsite mains and qualifying offsite mains can be laid by an accredited Self Lay Organisation (SLO) on behalf of the customer under the terms of a Self Lay Agreement (SLA). In exchange Anglian Water will adopt the mains laid under the agreement for a calculated asset payment equal to the estimated projected future revenue, over twelve years, of the mains covered by the Agreement.
It is important to note that this scheme is independent of the Approved Plumber’s scheme and only companies accredited under the Self lay scheme are eligible.
