Notes for CSO & STW Design in UK
(OP)
I am about to start designing CSO's and STW's within the UK. Does anyone have any guidance sheets or notes for this, as i have no experience in the work, and would like to get a bit of knowledge before i dive into the work?
Thanks in advance
Thanks in advance

What are you referring to as CSO's and STW's?

CSO's = Combined Sewer Overflows
STW's = Sewage Treatment Works
Thanks
RE: Notes for CSO & STW Design in UK
I think you mean 'combined sewers' as CSO's are, if I recall correctly, unplanned (undesired) overflows from combined serwers.
I cannot imagine that north american and UK practice are so different in this area - except that maybe the UK possibly has older works still in service.
Back in my undergrad, we used the Metcalf & Eddy 2-volume set for my sewer design class and unit processes class.

The authority may or may not use British standards.
There are also a number research bodies that put out excellent treatise on matters related to STWs. The Water Research Centre is the body I have in mind. They also have Codes and practices. http://www.wrcplc.co.uk/. Look at their bookshop.
RE: Notes for CSO & STW Design in UK
The Environment Agency will require all CSO's to be screened to 6mm in two directions, and depending on flows they may want a powered self cleansing screen. In an ideal world they would prefer an on or offline storm water storage system which will hold the flows and return them to the network when the storm subsides.
As for design guides there are a few about. There is an older publication published by the Foundation for Water Research (FWR) which I think merged with the Water Research Council "Storm overflow structures - a selection and design guide".
Another good, clear and straight forward book is "Urban Drainage" by David Butler and John W Davies.
As for WWTP design, Metcalf and Eddy is good, but is very heavily process orientated. From a civil perspective the best book I came across was "Wastewater Treatment Plant Design" by Syed Qasim, but it is American.

i have come across Urban Drainage in the past and has proved to be a very useful book... Im not an civil-engineer by degree, more a geological-engineer and it did explain things from 1st principles.
I will look into getting a copy!
