Water services, main renewals and replacement
Water main problems can generally be defined under four categories:
Faulty or deteriorated joints are also a common problem. The pipe material typically holds up better over time than the materials used to seal the joints. Pinholes, caused by internal or external corrosion will, in time, cause the main to leak and subsequently fail.
Lack of sufficient hydraulic capacity is another problem impacting water mains. With the extensive growth experienced in many parts of the country, older mains, in some cases, do not have sufficient hydraulic capacity to service the new customers and need to be replaced with a larger pipe.
