Water & Wastewater Engineering Services

Delta Precision Group provides managed engineering teams for municipal water and wastewater projects, from hydraulic modeling and pipe sizing to lift station design and permit compliance documentation, giving utilities and firms real capacity without a matching increase in permanent headcount.

Water System Design Wastewater & Lift Stations Compliance Documentation

01 / WHEN SYSTEM PERFORMANCE MATTERS

Built for the utilities and firms whose systems have to perform under load.

Municipal utilities running an expansion or rehab

Bigger than in-house engineering can carry — often the utility engineer trying to get a WaterCAD or SewerGEMS model built and calibrated before a capital budget cycle closes.

Consulting firms with a water or wastewater deliverable

That needs real hydraulic modeling experience, not just drafting support — often the PM whose NPDES permit renewal is stuck behind a documentation backlog.

If either of those is your situation, tell us where things stand — we’ll tell you honestly what it would take to help.

02 / THE CAPACITY CHALLENGE

Why utilities and firms bring in outside engineering capacity for water and wastewater projects.

A water distribution model that doesn’t correctly reflect pipe sizing and Hazen-Williams friction losses will underperform the moment real demand hits it, and a wastewater collection system with an undersized lift station shows up as a sanitary sewer overflow, not a line item. This is a discipline where the consequence of a design error is public health and regulatory exposure, not just a resubmittal.

Hiring to cover a project surge is slow, and a generalist drafting shop can produce a set of plans without necessarily understanding how a treatment process or a hydraulic model is actually supposed to behave under load. Water and wastewater engineering takes real technical judgment about system performance, not just software operation.

We build our teams around people who understand hydraulic modeling and treatment process design as engineering disciplines, not a drafting task with a specialized vocabulary attached.

03 / THE ENGINEERING WORK

Water and wastewater engineering support across planning, design, and project delivery.

Deliverable 01

Water system design support

Distribution and treatment system design, including pipe sizing and hydraulic modeling in tools like WaterCAD or EPANET, built to your utility’s design standards.

Deliverable 02

Wastewater system design support

Collection system and lift station design, and treatment process support, modeled in tools like SewerGEMS and checked against Ten States Standards or your governing agency’s equivalent.

Deliverable 03

Compliance documentation

Documentation support for NPDES permitting and other regulatory review tied to a water or wastewater project.

Who this is for: municipalities and utilities with system design work beyond internal engineering capacity, and consulting firms managing water/wastewater deliverables with a limited in-house hydraulics team.

04 / FROM SYSTEM TO SOLUTION

How we build engineering support around your utility’s requirements and project needs.

  1. We establish the governing standard and platform. We start by understanding the design standard your utility answers to, whether that’s Ten States Standards, a state-specific equivalent, or your agency’s own criteria, along with the specific modeling platform your system data already lives in.
  2. We model against your real system data. From there we build or update the hydraulic model directly against your existing system data, not a generic template.
  3. Assumptions are agreed before anything is final. We coordinate with your engineer of record on design assumptions before finalizing anything.
  4. Permit documentation runs to your deadline. We turn permit documentation around against your actual regulatory deadline, not a generic production schedule.
  5. You see the assumptions, not just the report. You get visibility into modeling assumptions and results as the work progresses, not just a finished report.

05 / WATER SYSTEMS EXPERTISE

The engineering, modeling, and documentation capabilities behind our utility work.

Capabilities our team is equipped to deliver

  • Water distribution and treatment system design, including hydraulic modeling in WaterCAD or EPANET
  • Wastewater collection system and lift station design, modeled in tools like SewerGEMS
  • Compliance documentation for NPDES and related regulatory review

Scope, the governing design standard, and modeling platform are confirmed with you before work begins.

06 / THE DELTA Precision GROUP DIFFERENCE

Engineering capacity built around system requirements, project standards, and delivery needs.

We treat hydraulic modeling and treatment design as engineering work that has to perform under real conditions.

Not a documentation exercise — which is why we coordinate directly with your engineer of record on modeling assumptions before anything gets finalized. That is the difference between a model that matches your system and one that just runs without errors.

We’re built for utilities and firms with recurring water and wastewater engineering needs.

Though a single system update or permit package is a reasonable way to start.

07 / FIND THE RIGHT FIT

Choose the engineering support model that fits your utility project.

Dedicated production capacity

An ongoing engineering team sized to your utility’s system planning and permitting cycle.

Project capacity

A single system design, model update, or compliance package with a defined scope and deadline.

Surge and overflow support

Additional engineering capacity ahead of a permit renewal or a capital budget deadline, released once the surge clears.

Not sure which fits? Tell us where things stand and we’ll recommend the right approach.

08 / FAQ

Frequently asked questions about water and wastewater engineering services.

Will the hydraulic model actually reflect how our system performs, or just run without errors?

We build and calibrate models against your actual system data and coordinate assumptions with your engineer of record, rather than delivering a model that runs clean but doesn’t match reality.

Do you have real water/wastewater engineering experience, or is this drafting with the right vocabulary attached?

Our teams are built around hydraulic modeling and treatment process design specifically, using tools like WaterCAD, EPANET, and SewerGEMS, not a generalist CAD pool.

Will this slow down our permit renewal timeline?

We confirm your regulatory deadline and governing standard upfront and turn documentation around against that schedule, not a generic production timeline.

How do you handle sensitive utility system data?

Data handling is confirmed with you at the start of every engagement, matched to your utility’s and any regulatory requirements.

Can we start with one system update before anything ongoing?

Yes, a single model update or compliance package is a common and reasonable starting point.
