To agree appointment of Willow
Pumps Ltd to undertake role of Principal Contractor to complete
detailed design and construction of the proposed replacement works
in the sum of £140,714.90.
 
The Council-owned, managed and
operated Sewage Treatment Works at Fen Road, Guyhirn is due for
replacement. This asset is over 30 years old and requires a
significant capital investment to offer effective service function
for the next 25 years for its connected customers; whilst
maintaining compliance with the Council’s legal requirements
in relation to the Environment Agency Final Effluent Discharge
Consent criteria set for this site.
 
The project delivery has been
undertaken in compliance with Council’s Code of
Procurement.
 
Decision Taken:
The Portfolio Holder for
Assets, Business Premises – Health & Safety & Food
Safety, Environmental Services & Heritage to approve the
appointment of Willow Pumps Limited as Principal Contractor to
undertake detailed Design and Construction (Option 2) for the Fen
Road Sewage Treatment Works Replacement Scheme for a sum of
£140,714.90. 

Reasons for the decision

In 2007, as part of the Housing
Stock Transfer process, Members agreed that the Council should
retain the STW and PS assets and not lose the considerable sum of
money from the Capital receipt of the Stock if the assets and
responsibility were to be transferred to Roddons Housing Association.
 
Members agreed that there was a
requirement to continually undertake investment to maintain service
function and EA compliance. To date approximately £1.5M has
been invested in replacing the ageing assets with modern, fit for
purpose, energy efficient small package sewage treatment
works.
 

Alternative options considered

Options to remove liability and
transfer incoming flows to an Anglian Water Services (AWS) system
were considered during project feasibility stage.
 
However, in this instance it
was not viable as AWS do not have assets located in the vicinity of
this site and the anticipated cost to pump the effluent to the
closest location was not deemed good value for money.
 
This existing WPL HIPAF plant
has come to the end of its useful operational life and requires
removal from operational service.
