We also let- ter-dropped every road two weeks ahead of actually going into that road. If we had any enquiries come back – for example, we had a customer say they were moving on a cer- tain date – we would make our working arrangements around them." Further efforts were made to reduce the burden of work for both the project team, which had 15 months to complete the work, and the public. Surveying work Prior to getting underway, Southern undertook an exten- sive survey programme, involving 82 trial pits and 37 coupon extractions, to deter- mine which pipes along the 37km network it could afford to leave in place. Around 2km of water mains were identified as polyethylene, which therefore did not need to be replaced, while Flowserve provided life expectancy advice on the pipes using radar imaging. "We also managed to descope areas or pipes that had self-cleansing velocities because we proved that they were not the cause of the higher iron content," Newman says. The remaining replacement work still involved Medway Maritime Hospital – the largest and busiest hospital in Kent – but the project team was able to remove the need to lay a main ONSITE PIPES AND PIPELINES 12 WET NEWS MAY 2018 | wwtonline.co.uk a'er reviewing the design drawings. "There's an access road towards the hospital called Montgomery Road and our engi- neers worked with Southern's engineers, ETS, to negate hav- ing to lay that section of main," Bird says. "There's only one route into the hospital for ambu- lances and buses, so obviously we were keen to avoid undertak- ing works with traffic lights that could have stopped an ambu- lance getting in." Even so, there was no getting around the need to replace the main in the primary entrance to the hospital. "We had to remove some redundant ironwork which actu- ally meant closing the entrance to the hospital," Newman says.
