CIV6746 Design and Management of Sewer Systems

Introduction - CIV6746 Re-assessment

This?module?has?one?component?for?there-assessment:

(i) a written?report containing two?parts?(each?2?parts described?below?in?detail) -?a?single?report worth?100% of the?module?re-assessment grade.

Part?1?reports on?knowledge gained?in the?module?(50% of?module?re-assessment grade),?Part?2?reports on the completion of a?storm?sewer?overflow?design?(50%?of?module?re- assessment?grade).

The?module?re-assessment?is an?individual student?assessment.

Written Report: Part 1 - Knowledge

One of the?Learning Outcomes of this module is to gain knowledge on?methods used to design?and operate sewer networks. This ?Learning Outcome to demonstrate your knowledge is?assessed?using a structured written?report.

In this?report, you should describe you?understanding?of:

1. ??Key components of?sewer networks,?how?they?are?linked?into?networks?and?how?their?performance can?be simulated.

2. ??Describe the software tools used by engineers?to design sewer networks, explain?the?underlying simulation approaches, and explain the uncertainties inherent in these models.

3. ??Describe the expected?performance?standards?for?sewer?networks?and?explain?how?these?standards?are?ensured?in the?UK.?Explain the?role of?economic,?environmental?and?health?regulations?in determining expected standards of?performance.

4. ??Describe?the major challenges?facing?sewer networks?over?the?next?three?decades?and?describe approaches that are?being developed to?meet these?challenges.

Assessment Requirements: Part 1

This?learning?outcome?will?be?assessed?based?on?the?first?part?of?an?individual?report?(the?overall written report is?100% of the module re-assessment grade,?Part?1?is 50%?of the?module?re-assessment?grade).?The?first part of this individual report should address the ?4 ?items?outlined above. This part of the written?report should be no?longer than 5000 words?in?length.?The?quality?of?referencing?is?important,?and?you?should?clearly?describe?the?sources?used?to?support your descriptions and explanations. The quality and?relevance of any figures or tables?is?important?and will also?be assessed.

The assessment guidelines?Part?1 of the?report?are:

1. ?Quality of the technical?information,?its detail and?coverage ?????????????????????????????????50%

2. ?Quality of any?argument?and?explanation ??????????????????????????????????????????????????????????????????30%

3. ?Structure of the?report and clarity?of?executive?summary?and?conclusions ????????10%

4. ?Quality of?presentation of?report?(English?language, figures,?references) ???????????10%

Written Report Part 2 - Sewer Overflow Design

You?are?to?examine?a?combined?sewer?system?that?contains?a?storm?sewer?overflow?(SSO).?The?existing?overflow?is?potentially?deficient?and?is?the?subject?of?an?investigation?by?the?Environment Agency.

The storm sewer overflow (SSO) is located at manhole SK35393201?(as?shown?on the?provided?layout?plans)?and?has?been?identified?as a “serious?concern”?by the?Environment?Agency?as?it?is?believed to?be failing to?meet?the?new?frequency?targets?in?Defra’s?Storm?Sewer?Overflow?Discharge?Reduction?plan.

There?is?also?significant?concern?locally?about the?discharges from this?SSO?into the?receiving?watercourse causing?“environmental?harm”?. The water company?has?already?instigated?a?12-?month?water ?quality ?monitoring ?campaign ?to ?ascertain ?whether?this ?overflow ?meets ?the?Fundamental?Intermittent?Standards for?intermittent?discharges.?River water?quality,?rainfall?and event duration?monitoring data associated with?this?overflow?is?therefore?available.

You?are?invited?to?design?a?SSO?replacement?scheme?that?is?to?be?undertaken?as?part?of the?water company’s?business?planning?in?response to these concerns.?It?is?proposed to?abandon?the?current?problematic SSO?and?build?a?new?SSO?and?storage tank to?address the frequency?and ecological?harm concerns on the?receiving?water.

It?is?up to you as the designer to?investigate the feasibility of providing?a?storage tank?solution?to?mitigate?the?detriment?on?the?receiving?water?from?intermittent?discharges.?A?previously?build?hydraulic?model?has?been?initially?reviewed?by?a?modelling?consultant?and?an?export?of?this?model?local?to?the?SSO?site?have?been?provided?in?addition?to?the?results?of?the?water?quality monitoring, rainfall and event duration monitoring.?Initial?assessment?of?the spill flows?predicted?in the?currently?available?model?suggest that?a?reasonably?sized?storage volume to?reduce the?number of spills and?mitigate impacts in the?receiving water to?an?acceptable?level?can?be?achieved.?However, this?model was?constructed,?calibrated?and?verified?several years?ago?and?may?be?out?of?date?given?population?growth?and?land?use?change?in?the?upstream?catchment. This uncertainty should?be considered in your design. Any solution should also?not?increase flood?risk about current?levels in the contributing catchment. As the design?engineer,?you?have?been?commissioned?to?complete?the?initial?feasibility?investigation?and?outline?a?storage-based?design and?provide a?report to the client?detailing the following?objectives.

1. ???Describe your?understanding of the?project?brief and the?requirements of?the?project.

2. ???Provide?clear?guidance?to?the?client?(the?water?company)?on?their?obligations?under?the current and emerging?legislative frameworks that govern the?UK water?industry?in?terms of SSO pollution and flood management, and any other associated design?standards.

3. ???Provide a detailed description?of your?design?to?deliver?a?solution?that?would?ensure?that?intermittent discharges from the?improved overflow would?be compliant?with?current and emerging?legislation.?Key considerations for your?design:

a. ???Detail?how?you?consider?any?storage?volume?would ?be?best?configured?to?be?compliant.

b. ???Your storage tank should?not?retain sewage for?longer than 8?hours duration?in?order to reduce the risk of septicity. Specify how you would recommend?controlling this outlet flow from your tank.

c. ???Provide?details?on?how?you?would?propose?to?convey?flows?from?the?current?system?into?your?tank.?This?will?require?careful?consideration?of?how?you?will?connect?into?the?live?existing?sewer?and?provide?information?on?how?you?will?manage sewer flows during the?construction?phase.

4.???This?is a feasibility study and there are?limitations on available?data.?Provide?details?on?what?additional?data?may?need?to?be?collected?and?any?other?investigations?required?to?both?reduce?risk?associated?with?the?construction?of?your?proposed?storage?tank?and data requirements for improving the hydraulic model and associated?prediction?of?the design inflows (model risks). Clearly explain any uncertainties in the design method?and your?resulting solution.

5. ???Describe the long-term risks associated with the proposed solution and how they could?be?mitigated. This?should?include?an?assessment?of?the?potential?impact?of?emerging?regulations,?climate?change,?urban?creep?and?operational?issues?(such?as?energy?use,?sedimentation, the build-up of fats, oils and greases). Describe what should be?undertaken in order to mitigate the risk of such occurrences, including proposed?maintenance?regimes,?and?if?you?believe?necessary,?details?of?how?the?system?could?be adapted?in the future to cope with?long-term?change?if?required.

Assessment Requirements: Part 2

This?element?of?the?overall?module?will?be?assessed?based?on?Part?2?of?an?individual?written?report?(Part?2?is worth?50%?of the?module?re-assessment grade).?Part?2?of the written?report?should contain?information?on the 5 objectives outlined?above.
