The Developer Services Team at Dŵr Cymru Welsh Water (DCWW) engaged Burroughs in the completed design of a foul sewer requisition to serve a multi-phased housing development at Genwen Farm in Bynea, Llanelli. Burroughs provided Drainage Design, Principal Designer, NEC Supervisor and Project and Contract Administration services for the scheme.

Burroughs undertook all drainage design including additional development phasing comprising a further 190m high-level sewer to connect the existing public sewer to the new Persimmon housing development. During the construction phase Burroughs acted a project manager under NEC3 Option A form of contract working with client Dŵr Cymru Welsh Water and Contractor Alun Griffiths.

The project involved significant physical and ecological constraints including working along a narrow public footpath with dense overgrown trees and hedges as well as the presence of Japanese Knotweed within the site. To deal with these constraints the project team engaged environmental specialist Spencer ECA to undertake vegetation clearance prior to commencement to allow adequate working space and access for plant. Burroughs engagement managed the specialist suppliers such as Spencer ECA who provided the Management Strategy for the treatment of Japanese Knotweed located at the site area prior to commencement, undertook regular supervision of Knotweed treatment during the works and contracted to provide Japanese Knotweed management for 5 years following project completion.

A number of measures to prevent the spread of Knotweed were put in place by Alun Griffiths and monitored by Burroughs in accordance with the agreed Management Strategy. Preventative measures included a clearly segregated contaminated / non contaminated boundary with enforced boot wash and plant washdown facilities along with the careful management and disposal of contaminated surplus arisings.
