Although <br /> <br />an acceSS road must be pioneered for the <br /> <br />new pipeline and improvements made as monies <br /> <br />permit, the steeper grades will not be <br /> <br />accessible in periods of bad weather. The <br /> <br />steeper gradients also require additional <br /> <br />access manholes to dissipate the velocity. <br /> <br />Re-routing will be required in several places. <br /> <br />This will require easements-. or direct land.~- <br /> <br />purchase. <br /> <br />In all previously described Alternates, proper <br /> <br />appurtenances will be installed to adequately prevent air <br /> <br />pockets, excessive pressure and water-hammer. At high <br /> <br />points where air may collect, air vacuum and relief valves <br /> <br />will be installed. Low places where water pressure can <br /> <br />build up, will require pressure relief valves. Pressure <br /> <br />on the line will be controlled by use of pressure reduction <br /> <br />valves. All altitute valves, solenoid valves and pump <br /> <br />control valves will be slow open-close type. No fast <br /> <br />29 <br />
