There is only so much the Nairn sewage and drainage systems can take in heavy rain before some of it goes into the river. We hear from Cawdor that there has been 32.8mm of rain in just over 12 hours up to around lunchtime - we will have had the same if not more here. That should perhaps ensure a bit of a summer spate in the river which will hopefully flush out any build up of pollution today.
Above you can see the overflow going straight into the River at the Factor's Pool this morning. The grey streak gradually spread out further down to the the A96 bridge and then claimed the river as its own. Sometimes the rainfall is so heavy that this will inevitably happen. Incidently, Nairn's drainage infrastructure is referred to in the submission to the Nairn South Planning hearing (next week) by the Commuinty Councils and others. They state:
"6.5.1. Water and drainage. The issues have been outlined in the joint CC paper on the subject submitted to the Reporter in January 2014 [ref doc #18]. It is essential that development on the Nairn South site is subject to conditions and obligations which ensure water supply, no additional risk (of flooding or pollution) to the river or the areas of Nairn downstream (north) of the site, and satisfactory arrangements for wastewater treatment. [ see in particular Sections 8 and 9 of the joint CC paper]. Scottish Water has already identified capacity problems, and expects these to be addressed via developer contributions. Since these issues have already been identified, this points to a requirement in planning conditions to carry out a Stage 2 DIA before any development proceeds (not after problems of flooding and foul drainage appear). Similarly conditions should require SUDS arrangements to be agreed and in place by a fixed timetable ahead of other development construction, not left for later delivery."
