The sewerage industry needs to understand and reduce embodied carbon dioxide emissions associated with its assets in order to contribute to the national carbon dioxide reduction agenda. There are at least six recognised methodologies for calculating so-called 'carbon footprints' of construction products and tens of standard-based or adhoc calculators. With the increase in information from different sources, the use of different methodologies and the absence of representative data and data collection methods, there is a risk that inappropriate data, results or methods are used to justify crucial decisions in the sewerage sector.
This new paper presents an assessment of the problem and its impact on the reliability of embodied carbon dioxide emissions data for large diameter (>225mm) sewer pipes.
Spring 2015 heralds major changes in the UK for the delivery of Sustainable Drainage Systems (SuDS). Recognising this, CIRIA’s Susdrain project has launched a new infographic on SuDS that provides a simple overview of the drivers and benefits. The ‘Going with the flow’ infographic details some of the key objectives and outcomes from a sustainable drainage approach. This includes improvements to local flood risk management, water quality, landscape amenity, and biodiversity.
The infographic is based on four case studies from both new build and retrofit examples, which demonstrate what can be achieved with early engagement and appropriate design. The case studies highlight how SuDS can manage local flood risk, enable savings in construction costs and deliver great places and spaces.
CPSA is a Supporter of the Susdrain project, which provides a valuable range of resources for those involved in delivering SuDS. The website, www.susdrain.org, together with face-to-face seminars provides a community for sharing information, guidance and experience supporting SuDS delivery.
Storm Water Attenuation Tank Factsheet
A new attenuation tank Fact Sheet has been published identifying the benefits of below ground storage of surface water within sustainable drainage systems and important factors to consider when selecting a proprietary underground tank system.
The attenuation tank Fact sheet highlights the challenges of design and installation complexity, accessibility for inspection and maintenance, capital & whole life cost, longevity and sustainability. It also explains the importance of good structural design.

SuDS solution combining Concrete Proprietary Drainage Products with Soft Landscaped Drainage Features.
Susdrain.org has published an excellent case study demonstrating the intelligent combination of vegetated components with proprietary precast concrete SuDS systems to achieve a technically valid sustainable drainage system and commercially viable housing development for Jelson Homes at London Road, Markfield, Leicestershire LE67 9UR.
CPSA will attend six Construction CPD RoadSeminar events throughout 2015 presenting the well-received seminar "Surface Water Management using proprietary precast concrete SuDS systems". The free CPSA seminar provides background to SuDS legislation and outlines appropriate solutions using a range of alternative SuDS components and systems.
RoadSeminars attended by CPSA: Manchester 15th April; Leeds 16th April; Edinburgh 14th May; London 2nd July; Nottingham 7th October; London 12th November. Please refer to Construction CPD certification services web site for details of the full RoadSeminar programme.
