Fine Options for the Essential Blocked Drains Now
An underground drainage network represents a large financial investment. There is no better way to protect this investment than to periodically and thoroughly inspect and maintain the network. Even a well-designed network that has been built to last a lifetime needs careful maintenance. This technical sheet provides useful information for the initial inspection and follow-up inspections as well as for the maintenance of an underground drainage system. The Blocked Drain Essex happens to be perfect.
The five keys to an effective underground drainage network are:
- The quality of the materials of which are made, in particular, the pipes, the casing and the filters if necessary, the fittings, the risers, etc.
- The quality of the design, which must be entrusted to a drainage contractor with the necessary permits or to an engineer.
- The quality of the installation, which must be entrusted to a drainage contractor holding the necessary permits.
- Compatible land management practices.
- Periodic inspections and maintenance operations.
After the first few years after installation, well designed and constructed drainage systems require minimal maintenance and repair. However, it is important that a new underground drainage system is carefully inspected and maintained for the first two to three years. It is possible to correct any problems affecting the side drains and main collectors and to backfill any areas that have subsided. You can expect maintenance work to be done every year, but it is minimal in most systems.
Importance of the network plan
A plan indicates the location and arrangement of side drains and main collectors, outlets, surface water inlets and works in the field. This document is valuable for future consultation. Keep it with the deed of land purchase, so that the data on the drainage network follows the official documents if the land changes hands. Some municipalities require or allow the retention of drainage system plans in their offices. They thus constitute a permanent register useful for locating drains during any work aimed at repairing drainage pipes or improving the network.
A good drainage plan includes the following:
- Construction date.
- Name of installer (i.e., contractor or owner).
- Changes from the original plan.
- Lateral drain data (spacing, diameter, depth, slope, area and material).
- Collector data (location, material, dimensions, depth, slope and capacity).
- Details of any difficulty encountered during installation.
- Location of outlets, surface water inlets and structures.
- Location of utilities, sandy areas, streams, etc. that can potentially affect the maintenance of the network.
The contractor must give a copy of the plan to the owner upon completion of the installation. If the contractor failed to provide a proper plan or if the owner did the installation himself, a simple pencil sketch that provides the same information is acceptable. In the absence of a good plan, order an aerial photo of the worked area, to get an overview of the drainage network.

In this country, contractors are increasingly using GPS tracking systems to obtain surveys and install drainage networks. A GPS system generates a detailed map of the drainage network which shows the exact location of it as well as the peculiarities of the field (boundaries, contour lines, etc.). At the end of the work, the contractor is able to provide the owner with a printed plan or a digital version of the plan.
