Control of infiltration to sewers (R175)

Sewerage undertakers, asset managers and capital works engineers, cut your costs with the help of this guide. Infiltration of groundwater into sewers can mean increased operational and capital costs in the sewer network and at the treatment plant. Most sewerage systems in the UK suffer from infiltration to some extent, but despite the problems it causes, it is not always possible or cost-effective to reduce or eliminate it.

This guide will give you the necessary tools to assess the need for, and prioritise, works to reduce the infiltration of groundwater into sewerage systems. It reviews the scale and causes of infiltration, and describes the techniques available for locating the source of the problem and renovation techniques and costs.

Keywords: pollution prevention, sewerage, urban hydrogeology.
