Horseshoe Bay Sewer Scope & Utility Locating

The problem

A high-volume kitchen was days from a health inspection with a floor drain that would not clear. The operator had already replaced fixtures inside the building on the assumption the problem was upstream of the slab.

Our approach

1. 1Responded same day given the pending health inspection and scoped before selling any work
2. 2Jetted the kitchen line back to bare cast iron and cleared the submerged interceptor outlet tee
3. 3Confirmed on camera that the cast iron was sound, ending the fixture replacement theory
4. 4Set the pump-out and jetting interval from measured grease loading and left the video on file for the inspector

The problem

The GC was three weeks from turnover on a retail shell and the building sewer kept surcharging into the loading dock trench drain after every rain. Two prior contractors had rodded the line and called it clear. Nobody had put a camera on it, so nobody could tell the owner whether the problem was inside the building, in the private lateral, or in the City main.

Our approach

1. 1Set up on the downstream cleanout and ran a self-leveling CCTV crawler upstream through the full building sewer, logging footage marks at every defect
2. 2Coded each observation to NASSCO PACP so the structural calls could be defended to the owner and the City
3. 3Sonde-located the offset joint and paint-marked the dig window on the dock slab
4. 4Verified the City tap and downstream main so responsibility was settled before anyone priced a repair

The problem

Six kitchen tenants shared one 6-inch cast iron main under the slab. Backups were hitting the two tenants furthest downstream about every ten days, and the property manager was absorbing after-hours emergency calls with no evidence of who or what was causing it.

Our approach

1. 1Scoped the 6-inch main first to separate a maintenance problem from a structural one before any jetting was quoted
2. 2Ran warthog and chain-free nozzles overnight from downstream to upstream so grease was carried out, not packed forward
3. 3Cleared the interceptor discharge line in the same window so the main would not reload
4. 4Re-scoped the full run on camera before opening and issued footage-marked video tied to each tenant tie-in
