Stormwater is rainfall runoff; sanitary sewer carries wastewater; supply plumbing carries water to fixtures and equipment. Keep those systems separate when describing a wet area. Timing and safe observations help identify the next investigation, but appearance alone does not establish the source. Private rainwater drainage does not include sanitary sewer repair or an assumed sewer connection.
Quay’s drainage inspection service concerns the private runoff route. This distinction matters before selecting a contractor or product. A lawn drain cannot repair every kind of underground leak, and an unexplained wet patch should not automatically be connected to whichever buried pipe is easiest to reach.
Identify rainfall-related behavior
Record whether water appears during rain, after roof discharge begins or as runoff crosses paving. Show where it collects and whether it recedes when surrounding surfaces dry. Roof outlets, surface falls and receiving-water backup can all influence rain-related behavior. The standing-water guide helps organize a sequence without entering unsafe conditions.
A rainfall connection is useful evidence but not a complete diagnosis. Several systems can be affected at once, and concealed routes may remain unknown. A private assessment should state what is observed and which source questions remain unresolved. Avoid treating a single photograph, color or odor as proof that the water is ordinary runoff or safe to approach.
Keep wastewater concerns in the appropriate scope
Sanitary wastewater and a suspected sewer problem require the appropriate provider and precautions. Do not route rainwater into a sanitary connection on the assumption that all drains serve the same destination. Likewise, a rainwater collector is not a substitute for investigating a wastewater concern. Quay’s offered scope excludes sanitary sewer repair.
If a request includes fixture-related symptoms or suspected contaminated water, describe that clearly rather than selecting a yard-drain service to fit the form. Do not enter or handle unknown water to gather a sample for an estimate. The contact page provides the site’s scope and operating information, while urgent hazardous conditions need the appropriate authority or emergency response.
Consider dry-weather water separately
A wet area persisting without rainfall can involve irrigation, supply plumbing or another source. Timing, nearby equipment and recent changes may help direct an investigation, but they do not certify which line is responsible. Avoid digging around suspected services or shutting unfamiliar equipment to test a theory before the appropriate professional is involved.
The inspection page explains the limits of private drainage observations. Known irrigation or private-line records can be useful context. A proposal should not assume that a new French drain is the right way to manage an unresolved leak, because collection may conceal or redirect a symptom while leaving its cause in place.
Understand the private stormwater route
For ordinary runoff, the route can include surface collection, subsurface collection where appropriate, solid conveyance and an authorized receiving point. Yard drainage explains the complete path, while downspout drainage covers concentrated roof water beyond the gutter system. Different sources may join only where the arrangement and receiver support them.
A nearby public inlet does not automatically authorize a private connection. The permit and outlet guide distinguishes permanent runoff routing from construction groundwater discharge. Groundwater encountered during excavation introduces a separate question; it should not be assumed acceptable for disposal simply because a stormwater inlet is visible nearby.
Avoid mixing collection and conveyance functions
Perforated pipe receives water from surrounding ground; solid pipe carries already-collected water along a defined route. Connecting a roof outlet or surface basin into an unspecified perforated line can release concentrated water near the problem area. The pipe-function guide explains why the route should be described by purpose.
Existing pipes may not have reliable labels or records. A visible cover or open end is insufficient to establish destination, condition or ownership. Before reuse, identify what can be checked and what remains unknown. A drawing should distinguish confirmed connections from proposed or assumed ones so later work does not rely on a mistaken system identification.
Choose the next step from evidence
For rain-related yard or hardscape runoff, request a drainage assessment with timing, sources and receiving observations. For sanitary or supply-water concerns, use the appropriate trade or public authority. For public street flooding, keep the reporting route separate from an estimate for private collection. A clear description can prevent an unsuitable service scope from being developed around the wrong water system.
The estimate checklist helps record what is known before construction is priced. The cost guide covers supported drainage budgeting context only; it does not provide sewer or supply-plumbing rates. Keep unresolved source questions explicit rather than converting uncertainty into a confident product recommendation or a promised repair outcome.
