Specifications include, but are not limited to: 2.2.1 Design of Temporary Waterline Design thermal insulated HDPE pipes for water distribution such that there is both pressure and steady flow at all service connections. The water line shall have a minimum service life up to three years at time of acceptance by DLNR. All bend fittings shall be restrained at the joints. Provide isolation valves with anchors (e.g. blocks and straps) at branch fittings. All local high points such as top at vertical bends shall include a manually operated valve to release trapped air. At minimum, all iron and steel hardware shall have a protective weather and corrosion-resistant coating. Walkway and AC roadway waterline crossings shall be buried with a 12” diameter ductile-iron pipe conduit for the 3” or 4” pipe to pass through and shall have a minimum of 30” cover. 2.2.2 Installation of Temporary Waterline and Appurtenances Install temporary waterline and appurtenances. Provide aboveground pipe support that is anchored into ground surfaces. The existing pressure reducing valve (PRV) manhole is set for a 100 PSI output. Due to the difference in elevation to the lower service connections, ensure that the system isn’t over pressurized by adjusting the PRV output pressure. Parallel bypass gate valve should not be opened. New piping must be disinfected, and pressure tested according to the technical specifications. Submit test results to DLNR for approval. 2.2.3 Reconnect to Existing Service Connections Locate existing service connection valve boxes and assess condition of laterals and valves. Connect to existing service laterals.
