plumbers Haringey History of water supply and sanitation
Water supply and sanitation has been a primary logistical challenge since the dawn of civilization. Where water resources or infrastructure or sanitation systems are insufficient for the population, people fall prey to disease, dehydration, and in extreme cases, death.
Major human settlements could initially develop only where fresh surface water was plentiful, such as near major rivers. Over the millennia, technology has dramatically increased the distances across which water can be relocated, but the availability of clean and fresh water remains a limiting factor on the size and density of population centers, and is expected to remain so into the foreseeable future.

Drum augers
A drum auger is a motorized auger with modular blades designed for various gauges of pipe. A drum auger is powerful enough to cut through tree roots. Used unskillfully, they can also damage plastic pipework and even copper tubing.
Roto-Rooter
Main article: Roto-Rooter
The Roto-Rooter is an electric auger invented in 1933 by Samuel Blanc, an American. His wife called the invention a Roto-Rooter, because the cable and blades rotated as they cut through tree roots inside sewer pipe. Competing companies made imitations after the Blanc's patent expired in 1953, but the machine is manufactured by and for a United States company called the Roto-Rooter Plumbing & Drain Service.

Plastic pipework
Plastic pipework is used for the conveyance of drinking water, waste water, chemicals, heating fluid and cooling fluids, foodstuffs, ultra-pure liquids, slurries, gases, compressed air and vacuum system applications.
Plastic pipe systems fulfil a wide variety of service requirements. Product standards for plastics pipe systems are prepared within the standards committee known as CEN/TC155. These requirements are precisely described in a complete set of European Product Standards for each application alongside their specific characteristics.
For example:
Conveyance of drinking water: Hygienic requirements
Conveyance of gas: Highest Safety requirements
Plastic pipes for radiant heating and floor heating: Temperature resistance over decades
Sewer applications: High chemical resistance.
Plastic pipes are perfectly capable of fulfilling the specific requirement for each application. They do so with a high level of performance over a long lifetime and with reliability and safety.
The key factor for success is achieved by maintaining consistently high quality levels. For plastic pipe products, these levels are closely defined by the different standards.
