 Brief Wessex Water is to supply the new development of 2000 houses in Poundbury with drinking  water. It has been determined that a pumping station (PS) at Burton will supply water from  the regional main to a service reservoir (SR) at Lambert’s Hill, which in turn will allow water to  flow by gravity to the urban development. There are therefore two pipes that need to be  designed, the pumped trunk main from Burton PS to Lambert’s Hill SR, and the gravity  distribution main from Lambert’s Hill SR to Poundbury. You are tasked with coming up with  different solutions, and outlining the most cost effective solutions; your designs will  encompass the route, pipe material, pipe diameter and, for the trunk main, the outline pump  arrangement. You will also advise on the need for pressure surge protection. The pipeline’s route will be governed by several factors, amongst them system hydraulics  (ground elevation and slope), land use (landowners, road / rail and river crossings), sensitive  areas (AONB, CWS, SSSI, SAM) and access (construction and maintenance). The pipeline’s  diameter will be governed by system hydraulics (pressure, flow, friction, length) and the  material will be governed by ground conditions and costs. R
