Things to check before you order
Foul or surface water?
Foul (sewage) and surface water often need to go to different places. Check where your drains connect before you order.
Building over or near a sewer
Building near a public sewer may need permission from the water company. Check before you dig.
In Northern Ireland building work follows the Building Regulations (Northern Ireland), with guidance in the Technical Booklets, and applications go to the council's building control team.
Getting drainage onto your Holywood site
Pipe travels in 3 m and 6 m lengths; fittings and chambers come boxed or loose with the load. Deliveries to Northern Ireland include a sea crossing, so we quote each order individually.
- Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
- In summer Holywood gets around 17h 17m of daylight, but early deliveries still beat the traffic and give the longest working day.
- Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
Your questions answered
Can I connect to the public sewer?
New connections to a public sewer usually need approval from the local water company.
Can I add other materials to my Holywood delivery?
Yes. Put everything on one list, from drainage to fixings and PPE, and we will price it as one delivery where the products can travel together.
Is there a minimum order for delivery to Holywood?
There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.
What do I bed drainage pipe in?
Usually pea gravel or a similar granular material around the pipe. We can add it to the order as bulk bags.
