Who does water and sewer engineering for new commercial developments in Arizona?
Arizona water and sewer engineering for commercial developments runs through city review, utility capacity and will serve letters, and here is who does it.
A civil engineering team does Arizona water and sewer engineering for a new commercial development by designing the utility connection and carrying it through the local development review. If your firm has the design but not the local review capacity, a partner can carry that part.
What does water and sewer engineering cover on an Arizona commercial site?
It covers the water service, the sewer service and any off-site main between the building and the utility's system. On the water side, the scope runs from the utility main to the building, including the service line and meter.
On the sewer side, it runs from the building lateral to the manhole or stub the utility names as the connection point.
Phoenix's description of its water and wastewater infrastructure (opens in a new tab) shows the range a commercial connection can meet: distribution mains down to 8 inches, service lines from as small as 5/8 inch up to 6 inches, and lift stations that use force mains to move sewage where gravity will not.
Who reviews the water and sewer plans in an Arizona city?
The city or county development engineering group reviews them as part of the development process. Gilbert's development engineering page (opens in a new tab) describes a development engineer who represents engineering through pre-application meetings, general plan amendments, zoning, design review, use permits, preliminary plats and annexations.
That review covers the utilities, not just the pavement: drainage, water, sewer, transportation and other public services. Gilbert splits plan review into pre-application, preliminary plats, improvement plans and final plats, and its inspections include sewer line flow, water line leakage and pressure, and soil density.
When should a project ask for a will serve letter?
Ask at pre-application, before the site plan is fixed. Gilbert lists water and sewer will serve letters among its development engineer's duties, and the same office handles pre-application meetings and preliminary plats. Ask the city which submittal it wants first.
A sewer determination letter is required before a septic system permit in Gilbert, and the same office issues water and sewer buy-in determinations. Those are local process items, so confirm them with the city before you scope the utility work.
How does a firm outside Arizona handle the utility scope?
A firm outside Arizona can design the work, but the local review still has to be carried by a team that knows the city or county process. MES's Arizona water and wastewater engineering page describes its Arizona work as site civil work for small commercial sites, with site plan and utility plan sheets taken through local review.
MES is licensed in Arizona and eight other states. That matters when a Texas or Colorado firm has the client and the design but needs Arizona production or review support.
Is your project ready to scope water and sewer engineering?
Ready means yes to every item below, with the document behind it. Each is a fact an engineer needs before a scope or a schedule means anything.
- Do you have the legal description, the site plan and the proposed building use, including the water-using fixtures and processes?
- Do you know which utility supplies water and which collects sewer at the address, and have you asked each about capacity?
- Is there an existing stub, manhole or meter at the property line, and at what elevation?
- Will sewage leave the site by gravity, or does the grade point to a lift station and force main?
- Has the city or county said which submittal it wants first, such as a will serve letter or an improvement plan set?
- Have you confirmed who will seal and carry the utility sheets through Arizona review?
You are ready to scope when every answer is yes. If two or more are unknown, the first meeting is about finding them, not about design.
Take this agenda to your engineer or project team: which utility owns the main at the property line, who applies for the will serve letter, and what the city's first submittal has to contain.
Scope and limits. This article is general education about how Arizona cities review water and sewer work on commercial sites, drawn from public city sources and MES's own Arizona page. Requirements differ by city, county and parcel, and nothing here promises a review outcome, an approval date or a design for your site. Those answers come from the agency reviewing the project and the engineer sealing the sheets.
Frequently asked questions
Who reviews the utility plans in Gilbert?
Gilbert's development engineering group reviews the engineering improvements for water, sewer and streets as part of the development process. The town's page lists plan review for pre-application, preliminary plats, improvement plans and final plats.
When does a will serve letter come up?
Gilbert lists water and sewer will serve letters among its development engineer's duties. Ask the city which submittal it wants first, and have the engineer supply the connection data the reviewing office asks for.
When should utility review start?
Start at pre-application. Gilbert's development engineer represents engineering through pre-application meetings, zoning, design review and preliminary plats, so the utility question can be raised while the layout can still change.
I run a small civil firm in Texas and a client just handed me a commercial site in Arizona. What should I check before I take the scope?
Check which city or county reviews the utility plans, what submittals it wants first, and whether your team has the Arizona capacity to carry the review. MES is licensed in Arizona and eight other states if you need a partner for that part.
I am a project manager for a developer building a retail center in an Arizona city, and the city wants a will serve letter before it will take our site plan. What do I give our engineer to get that moving?
Give the engineer the legal description, the site plan, the building use and the point where the site can connect. The city's process controls the letter, so ask the reviewing office what it needs, and have the engineer supply the connection data it asks for.
