Unless you have a natural spring or are planning on having a borehole on your land, the most common way to get a water supply is to connect a service pipe from the water main to your property. In most built up areas there's a water main in the road or footpath nearby which we can connect your property to. In more rural areas this may be further away and require a longer service pipe to be laid. For a new property to have its own water account it must have its own supply, this is usually needed when the property is sold. A domestic property would most commonly be connected by a standard 25mm connection onto our water main. This would provide a flow rate of up to 1 litre per second and a minimum of 15 metres (1.5 bars) pressure at the boundary stop tap.
If you want to replace your esisting supply because you need a larger supply or you want to change the entry of the water pipe into your site from the existing highway you should apply to us for a new connection or if you are converting the property into additional properties that will require their own water accounts they will need their own supply.
If you want to replace your existing supply because you need a larger supply or you want to change the entry of the water pipe into your site from the existing highway you should apply to us for a new connection.
If you're creating a commercial property you are most likely going to need a new water connection to our water main and a connection to the public sewer to take the sewage away. If the property needs a large amount of water, especially water used in industrial processing, you may need a large water connection and if you are disposing of this water into the sewer you might need special permission.
If you are building a new block of flats/apartments or converting an existing building into flats, you are most likely going to need a new water connection to our water main and a connection to the public sewer to take the sewage away.
If you need a new water supply for a trough in a field for agricultural purposes you need to apply for a standard water connection. You are responsible for laying a service pipe in private land down to the nearest existing water main for us to connect to. Once you have applied we may arrange a site visit and we’ll confirm where you should lay the service pipe to. We’ll send you the connection costs for the work within the public highway. A water meter will be installed at the point of connection in an external boundary box and you’ll receive an individual bill/account for this trough supply. This follows the same process as applying for a connection to a new house. No sewer connection is required.
If you're building multiple domestic or commercial properties on a site that will have a new road/access you'll probably need a new water main. You can choose either Affinity Water or a WIRS accredited Self Lay Organisation (SLO) to lay the new main and/or service connections.
If you are developing a site and require water for building purposes then you may want to consider applying for a temporary water supply to the site.
We offer a free replacement water connection if you live in an existing domestic property which has a water service pipe that is lead. The replacement connection we make will be 25 mm diameter and will be connected to the same water main as the existing supply. You will need to lay a new 25 mm service pipe out to the highway boundary. It is only available if the following is true: The property is occupied and has an existing active water account. The building is not undergoing a change of use or renovation by a developer who is selling the property. If you meet the above criteria you and would like to apply please go to our Lead pipe replacement page for further information.
If you don't meet the above criteria and you would like your existing water connection replacing or upsizing, you'll need to apply for a new connection.
