Land at Highover Farm, Hitchin
The surface water drainage strategy has been designed to allow water to drain naturally into an attenuation basin and an infiltration basin, which allow for slower discharge into the ground.
The drainage strategy will enable surface water runo to drain towards the north-east of the site, which is the natural low point within the site.
Use of an existing pond, provision of a swale and use of soakaways throughout the site will complement the basins and provide significant temporary storage at ground level for storm water, which will reduce peak surface water flows and help to filter pollutants.
The provision of on-site drainage will ensure that there is no increase in surface water run-off created by the development, whilst the drainage strategy will help to direct the flow of water into the storage network, helping to improve overall protection from flooding.
Foul drainage will be connected to a new pumping station which then be pumped to the Anglian Water network on Stotfold Road for connection into the system on Cambridge Road.
The image on this page identifies the key features of the proposed Drainage Strategy, which will be submitted shortly to the Council to discharge Condition 15 of the outline consent. Click each image to enlarge.
