Cross Connected Sewer tracing

Estimates of the number of cross connections from foul water outflows into the storm water sewer system vary widely from a few hundred thousand up towards 3/4 of a million miss connections. The financial burden on the water companies to resolve this is huge- so how can they attempt to reduce their costs and speed up remediation of these problems?

Cross Connected Sewer tracing

The problems in identifying and tracing miss connections are not solely down to being in the right place at the right time.  Visual inspection regimes can easily overlook issues which may not be manifesting themselves as grey water, ragging or odour problems.  A smarter approach is therefore required to not only help identify and trace these connections but also to reduce man hours, labour costs, vehicle leasing & maintenance costs and ultimately reduce & prevent penalties imposed by the regulators for pollution of water courses.

Of course it must be accepted that this is an uphill battle, constant development from whole estates to private extensions and down to DIY plumbing all add to the ever growing burden on the water companies resources.  But using smart technology such as the SMF4 from STS Instruments can help to start gaining the upper hand in the battle.  Using the SMF4 gives teams a portable, rapid on site means of testing the water in the storm drains for any signs of organic pollution derived from households and being wrongly directed to the storm drain. 

The instrument gives a virtually instant readout enabling the user to assess the quality of the water in the drain, a poor result can then be traced back up the network to the source.  The rapid results mean a more efficient work practice can be put in place and the number of return visits due to on going issues can be reduced.  By also keeping a record of readings in monitoring points around the network a picture can be built up of where efforts should be focused and then historical data can be used to check for new issues which arise.

A further benefit of the system is that samples can be dipped from deep and difficult access points therefore reducing the burden of health and safety compliance and of course the risk to individuals.
