A Guide to Drainage Systems in Auckland: Everything You Need to Know

If you are a homeowner or a business owner in Auckland, you know that drainage systems are essential to keep your property safe from water damage. Drainage systems are responsible for carrying rainwater and wastewater away from your property, ensuring that the water drainage system is safe to use. However, finding the right drainage system can be tricky, especially when it comes to Auckland’s diverse weather conditions. Here is a comprehensive guide to drainage systems in Auckland to help you make the right choice.

drainage Auckland experiences weather conditions that range from heavy rainfall to dry spells, depending on the season. Therefore, drainage systems must be suitable for its conditions. Two of the most commonly used drainage systems in Auckland are surface water drainage and sub-soil drainage.

Surface water drainage refers to the network of pipes used to carry surface water away from a property and into Auckland’s waterways. A surface water drainage system might include gutters, downpipes, and drains. Sub-soil drainage, on the other hand, involves the installation of perforated plastic pipes that absorb and disperse water from the earth’s natural drainage system. This system is more complicated than surface water drainage, but it is better suited for properties with a high water table.

Another type of drainage system is the soakpit, which is used to accumulate and soak away the rainwater running off the property, preventing flooding or water damage. Soakpits are shallow concrete pits filled with stones and rubble to allow rainwater to percolate slowly into the surrounding soil. They are ideal for properties where there is no natural drainage system or the water table is very high.

It is worth noting that building consent is necessary for most drainage plans, and you must ensure that the drainage system meets council standards. You must also work with a professional service provider who specializes in drainage systems in Auckland and understands the city’s unique weather conditions, such as Typhoon Plumbing.

When hiring a professional service provider, they will guide you on the best drainage system to use, depending on the property’s size, location, and ground type. They will also help you design the drainage system as stipulated in the council standards.

It is also important to note that regular maintenance should be carried out on drainage systems. Blocked drains, damaged pipes, and clogged culverts are some of the common issues that may arise in drainage systems. Therefore, it is prudent to have a professional service provider assess and maintain your drainage system annually. Regular maintenance saves you from costly repairs and inconvenience brought about by water damage.
