Site Servicing

A site-servicing package can include water, fire, sanitary, storm, foundation drainage, service chambers, maintenance holes, catchbasins, hydrants, valves, laterals, utility ducts, tie-ins, testing, backfill, and restoration. Harrowgate defines which public and private limits, permits, fees, bypasses, meters, and building penetrations are included before mobilization.

The deepest gravity service often leads because it has the least vertical flexibility, but the correct order comes from the coordinated profile and construction access. Harrowgate reviews every crossing, building entry, chamber, and connection before setting the sequence. In congested corridors, short sections of several systems may advance together rather than one complete network.

Existing crossings are daylighted where necessary and surveyed for horizontal position, crown, and invert. Proposed services are compared in profile for pipe outside diameter, bedding, joint location, insulation or protection, and required separation. Harrowgate raises a conflict before ordering a field deflection that could violate slope, cover, restraint, or municipal acceptance.

Requirements vary by system and authority. Water work can require pressure, leakage, flushing, disinfection, and bacteriological results. Gravity sewers can require visual inspection, CCTV, deflection checks, infiltration or exfiltration testing, and maintenance-hole review. Harrowgate schedules each test before restoration removes access to joints, valves, or corrections.

Yes, through the municipality's permit, inspection, isolation, and connection procedure. Harrowgate verifies main material, diameter, condition, pressure or flow, fittings, restraint, shutdown window, traffic control, and contingency materials. The receiving system is not opened until testing and authority release conditions are satisfied, and service restoration follows the approved sequence.

The structure base must be stable, bedding must extend correctly, and backfill must be placed in compactable lifts around the entire circumference. Confined equipment is used without moving the structure. Harrowgate pays particular attention to pipe entries, frame adjustment zones, and trench transitions, then verifies density before granular and pavement are rebuilt.

Provide approved civil plans and profiles, municipal comments, standard-detail references, utility composite, geotechnical and environmental reports, connection permits, shutdown limits, flow-control requirements, building entry drawings, testing criteria, restoration sections, and current survey. A responsibility matrix for meters, chambers, authority work, and private-property connections prevents scope gaps.
