Palmerston North is a virtually dead flat city located on a virtually dead flat plain with a large and dirty river flowing nearby. This poses a particular challenge for the city’s drainlayers, as there are very significant engineering challenges but making sure that the sewer and stormwater systems I working properly in all situations.
Drains by definition are there to drain water and wastewater away from the city to another location, and for this to happen efficiently the drains must have a constant slope. In a dead flat environment this is quite tricky, as the drains will need to be laid at certain depths at various points in the city to make sure that there is a constant slope and flow. One edge of the city will be upstream and the opposite edge will be downstream, and at the downstream point the drains may need to be many metres below the surface. This makes for an engineering challenge or any drainlaying.
Another problem for drainlayers is that the city is prone to surface flooding after heavy rainfall, and after particularly heavy rainfall across the region the local river is also prone to heavy flooding. While this is protected by very large stop Banks it’s still means that during a flood all the storm water drains can not drain into the river and must be closed off, otherwise the river will drain into the stormwater system and flood the city.
This makes for complicated work for any drainlayer who needs to understand exactly what the situation is at all points in the city with regard to the depths of the drains. Drainlayers in Palmerston North are generally pretty busy, because the housing stock is old and the sewer and stormwater drains from the houses and in the streets there’s also old.
A particular problem is that the sewers for the houses are generally made out of earthenware pipes, and these are very prone to penetration by tree roots and such like which can block the flow and caused a lot of grief for the highlighter or householder. In these situations a drain layer is an essential partner, and the simplest way for the distressed homeowner to solve their problem is just to do a Google search for drainlayers Palmerston North.
The modern drainlayer has all sorts of Handy Tools at their disposal to clear blocked drains in particularly where there are roots and such like growing through invisible pipes. The point of these tools is to try and avoid having to dig up the drains to repair them, business is almost always and costly and unpleasant business for everybody involved.
The good news is that drainlaying has from the early days been a pretty exact science in terms of the level and slope of the drains, and the modern drainlayer can be confident in almost every case that the actual drain alignment is correct, and all I need to do is to clear a blockage to remove a problem.
