a <br />PI <br />After reviewing them a ps to determine the start location, the opeiatorwilI fill the Vector tank 1 <br />with water utilizing the water meter obtained and secured by Houston & Harris as prescribed" <br />in the specifications for hydro - flushing purposes. This procedure will occur throughout the <br />day. The operator then assesses manhole locations ensuring the safest position of the <br />vehicle prior to setting up to begin the washing process. Included in this set -up procedure <br />3 are assurances of traffic cones around work area and equipment as well as the use of gas <br />detector meter readings indicating safe removal of manhole lids. Traffic control will be <br />provided per Work Area Traffic Control Handbook when necessary. <br />p <br />Once the location is deemed safe, the manhole lid is removed. The appropriate cleaning 1 <br />nozzle for the task is chosen and attached to the Vector hose. The operator starts on the <br />downstream manhole and runs [tie nozzle to the upstream manhole to hydra -flush the line <br />k as the hose is pulled back. When heavy debris is encountered, a vacuum process is also <br />applied to the line. Houston and Harris operators have utilized the vacuum process, along <br />with the hydro - flushing to provide the most effective combination of resources for success <br />in heavy debris. <br />After the hydro-flushing y g process is complete, the operator replaces the manhole cover back <br />an the manhole and safely moves to the next location. Documentation is validated by the <br />operator recording- all the required information on the tablet PC withtnfraMAP software' <br />supplied by the City. <br />Houston and Harris personnel possess experience and have demonstrated proficiency in <br />the infraMAP software. This experience and expertise will provide the maximum capacity <br />for smooth systems and coordination with the city's infrastructure. <br />61hf of 9an(a An., 0id 413 020 <br />Cloyed Cimvll Te(evl9lan (CCTV) Inspamlan of "nitir, seW '. <br />. ...... ...... <br />- -- 219918ulon Road <br />Orend l'nrmeq CA 92713 <br />p y+, ggg+�n xx.+ 904 t2E ll99PP 905.4n,0141P <br />CA U991167 <br />a <br />25E -28 <br />
