Hen and Duckhurst Pump Away  - Clancy

Hen and Duckhurst Pump Away Scheme

As the UK population grows, existing infrastructure can struggle to keep up with increased demand. At Hen and Duckhurst farm, there was a risk that the new mixed-use development of 250 homes and associated public open spaces would overwhelm the already stressed local pumping station. Therefore, Clancy were tasked to build a new attenuation tank – and any necessary pipework and manholes to connect the development to the existing sewer network – to provide the full foul-drainage capacity needed to reduce the risk of overloading the existing infrastructure.

The site posed numerous challenges, including a protected hedgerow and the need for a structural culvert design to account for highways loading as part of potential future developments in the area. The site additionally was on a floodplain, therefore flood protection had to be considered in all of Clancy’s designs. Clancy’s solution involved installing a precast concrete box culvert  attenuation tank complete with a 150mm dry weather flow channel laid on 150mm thick concrete slab, designed to bear load and alleviate any hydraulic effects on the culvert and reduce increased flood risks

Due to the environmental challenges of the site, Clancy ensured to undertake considerable public liaison, allaying local fears the new development would exacerbate the existing historical flood problems. The liaisons included virtual meetings with Parish Councillors and 1-2-1’s with concerned residents together with regular meetings with the developer.  Clancy also eliminated any impact to a locally significant and protected hedgerow, securing an alternative access point, and tunnelling deep under the hedgerow at the point where the pipes had to cross it. Clancy’s innovative design solution and construction methods resulted in a reduced programme duration and rewarding final update to local residents and the developer, with little or no complaints once the work commenced.

Providing for 250 new homes

Redesigned to protect local hedgerow

Extensive focus applied to local concerns

Regular and constant updates issued to keep the interested parties well informed

The area has had historical flooding issues and the development created major concerns, initially, that the solution would add to the problem. Clancy’s communications focused on the solution preventing any increase in historical flooding issues and direct positive contacts proved to me that Clancy did what we said we would do.

A local couple thanked our Customer Service Manager Steve Anthony by saying “your simple but detailed explanation of the scheme and it’s benefits to the area have been excellent. Please call in for a cuppa when next in Staplehurst”
