Dunedin is a large city, and like all large cities has a significant drainage network and a high degree of focus on quality drainage from the houses and commercial buildings in the city. There are quite a lot of drain laying companies in Dunedin, and the smart way for a homeowner or commercial building owner to locate a good drainlayer is to type in drainlayers Dunedin into Google search.
The drainlaying industry is reasonably heavily legislated, because safety and public health is extremely important in the community, and the drainlayers job is to make sure that the public health is protected and any work they do is done safely. When the homeowner is looking for a drain layer they should simply make sure that the drainlayer is fully qualified and if they are any doubt they should ask for references from prior customers.
The Dunedin terrain there’s two main features that add a degree of complexity for drainlaying work. Firstly a lot of the city is on steep hills, and this can create interesting problems around exposed sewer pipes down the side of banks, broken sewer pipes during land slippage after a large storm for example, and a pressurised sewerage system at the bottom of the hill. The same problems also exist for stormwater systems, and sometimes specialist knowledge as required by the drainlayer to work on these systems.
Another feature for Dunedin drainlayers that can complicate things is the very low level of land in the south Dunedin area. This not only causes flooding during rain storms, but the water table is also very shallow and rises and falls with the daily tides. All good Dunedin drainlayers will understand how this works in south Dunedin and will know how to work around it. For example they may need to work very quickly during the low tide to get a section of drain completely excavated and then to lay the new chain and backfill it. They will also understand that the backfilling has to allow for the fact that the drain will become buoyant at high tide.
One other problem in South Dunedin during and after rain storms is that the storm water system can overflow into the sewerage system simply because of the way these systems were constructed many decades ago. The stormwater system unfortunately empties into the harbour, and after every rainstorms sometimes sewerage can also find it’s way into the hardware as well. This can also cause a problem for other operators who may have underground plant and manholes for example that use the stormwater system for drainage, as sewerage can make it’s way into these manholes during and after a heavy rain storm. Such is the challenge of being a drainlayer in Dunedin.
