Water Engineering For California Developers

From planning to permits to construction, we handle all water engineering for your California development. Supply evaluation, treatment design, distribution systems, and hydraulic modeling. Projects that move fast and stay on budget.

Water Treatment Planning

Before you commit to expensive treatment equipment, you need to know what contaminants are in your water and what California requires you to remove. Your raw water quality determines everything. If you’ve got iron and manganese, you need oxidation. High hardness means softening. Arsenic or chromium-6 require specialized removal systems. Pick the wrong treatment approach and you’ll pay for it every month in chemicals and maintenance.

We review your water quality test results and recommend treatment technologies that actually match your situation. We compare options like membrane systems, ion exchange, oxidation processes, and conventional filtration, looking at upfront equipment costs, ongoing chemical expenses, operator staffing, and what happens to the waste you generate.

For new developments, we right-size treatment so you’re not paying for extra capacity you’ll never use. For existing systems with compliance problems, we figure out what equipment you can keep versus what needs replacing. You get a treatment approach based on your actual water chemistry and realistic operating budgets, not a one-size-fits-all package some vendor wants to sell you.

Water Treatment Permitting

California’s Division of Drinking Water doesn’t let you build or modify a public water system without their approval. Whether you’re drilling new wells, adding treatment equipment, or expanding capacity for more homes, DDW reviews your engineering plans to verify you’ll deliver safe drinking water that meets state standards.

We prepare the permit applications DDW requires, including engineering reports explaining your design decisions, detailed construction plans showing exactly what you’re building, and technical responses to their review comments. We coordinate the whole process from initial submittal through final approval, handling the back-and-forth with DDW staff until they sign off.

California’s permitting involves more than most states. Title 22 compliance for materials and construction methods, CEQA environmental review for larger projects, coordination with county health departments, and detailed monitoring plans proving your water quality. We’ve worked through DDW’s process enough times to know what documentation they need upfront versus what triggers delays. Your permit moves through review on a timeline that doesn’t stall your development schedule.

Construction Drawings

Once DDW approves your water system design, you need construction drawings contractors can actually use to bid and build your project. We produce complete plan sets in AutoCAD Civil 3D, including treatment buildings, pump stations, storage tanks, and distribution piping. Everything needed to go from engineered design to functioning infrastructure.

Every drawing includes detailed plans showing equipment layouts, profile views for underground piping, cross-sections through structures, and specifications that meet California construction standards. We coordinate with structural engineers on foundations and buildings, mechanical engineers on pumps and treatment equipment, and electrical engineers on power and controls. A California-licensed PE reviews every sheet before it goes out the door.

Contractors get drawings with enough detail to accurately price your project and build it correctly the first time. Clear drawings mean fewer questions during construction, fewer change orders when something’s ambiguous, and projects that finish on budget. You get bid-ready documents the same week DDW issues final approval.

Distribution Design

Your water distribution system has one job: deliver adequate pressure and fire flow to every property in your development. Size the pipes too small and customers complain about low pressure. Size them too large and you’re wasting money burying oversized infrastructure, which hits especially hard in California where construction costs run higher than most of the country.

We design water mains, service connections, isolation valves, and fire hydrants based on hydraulic calculations of your actual demands. We size each pipe segment to handle peak flows, configure loops so water circulates properly, space valves so you can isolate sections for repairs, and locate hydrants to satisfy fire marshal requirements for spacing and flow capacity.

Our designs account for California’s terrain. Hills create pressure zones that need careful management, and we coordinate with existing utilities you’re tying into. We phase the system to match your development buildout, so you’re not overbuilding infrastructure for lots that won’t sell for years. You get a distribution system properly sized for your site conditions without paying for capacity you don’t need or creating future pressure problems.

Hydraulic Modeling

You can’t afford to discover your water system doesn’t work after contractors finish installing thousands of feet of pipe. Hydraulic modeling tests your entire system on a computer before construction starts, checking pressures under peak demand, verifying fire flows at every hydrant, and simulating what happens when equipment fails or pipes break.

We build detailed computer models using EPANET and other industry-standard software that simulates real-world conditions. Normal daily demands, peak summer irrigation, multiple fire hydrants flowing simultaneously, pump stations going offline. We run every scenario that could stress your system. The model verifies your pipe sizes deliver adequate pressure, storage tanks provide enough capacity, and pressure zones are set up correctly.

Problems that show up in the model get fixed during design when they cost nothing to correct. Undersized pipes, inadequate storage, low-pressure dead ends. We catch these issues before bidding. By the time contractors start work, you know the system performs exactly as planned. No surprises, no emergency redesigns, no change orders to upsize infrastructure after it’s already in the ground.

Water Losses Analysis

If you’re buying property with existing water infrastructure in California, you need to know how much water actually reaches customers versus how much you’re losing to leaks, inaccurate meters, or unauthorized connections. Unaccounted water drives up your pumping costs, wastes treatment capacity, and creates compliance issues with state regulators. This is particularly problematic in California where water conservation is mandatory.

We perform water loss audits following AWWA standards that separate real losses (actual leaks) from apparent losses (meter errors and theft). We analyze production records from your wells or treatment plant, compare them against customer billing data, and evaluate system operations to pinpoint where water is disappearing and what it costs you.

For developers acquiring existing systems, this audit tells you the actual condition of what you’re buying and what repairs you’ll need to budget. California regulators expect water systems to control losses. High unaccounted water triggers enforcement actions. You get clear data on current system performance and realistic cost estimates for improvements needed to meet acceptable loss levels.

Booster Station Design

When your California development includes hillside lots or properties at the end of long water mains, gravity alone can’t maintain adequate pressure. Booster pump stations push water uphill and maintain pressure at distant points. When a booster station fails, customers lose water pressure, you risk contamination from backflow, and you’re paying emergency rates for after-hours repairs.

We design booster stations with pumps properly sized for your flow requirements, backup pumps that automatically activate when the primary unit fails, variable frequency drives that adjust pump speed to save energy, and control systems that respond to pressure changes without operator intervention. Each station includes proper inlet piping to prevent cavitation, surge protection for your distribution system, provisions for backup power during California’s wildfire season, and maintenance access that doesn’t require confined space entry.

The result is a booster station that operates reliably for decades. Pumps that handle varying demands smoothly, controls that don’t need constant adjustment, and equipment that runs without weekly service calls. You get infrastructure designed to California’s seismic requirements that performs correctly from day one and keeps performing

Pressure Reducing Vault Design

California developments built on hillsides often span several hundred feet of elevation change. Without pressure control, lower properties experience dangerously high water pressure that breaks pipes, damages fixtures, and generates constant customer complaints. Pressure reducing valves control these high pressures down to safe, usable levels, but only when properly engineered and installed.

We design pressure reducing vaults with valves sized to handle your flow ranges, bypass piping that maintains service during valve maintenance, pressure gauges for monitoring and troubleshooting, and vault access that allows adjustments and repairs. Our designs factor in your specific elevation differences, anticipated demand variations as development phases complete, and target downstream pressures that protect infrastructure while meeting customer needs.

You get pressure reducing installations that protect your distribution system from excessive pressure, maintain customer service within acceptable ranges, and operate reliably without constant maintenance. Valves that hold their pressure settings, systems that don’t require weekly adjustments, and infrastructure that manages pressure zones effectively without creating operational headaches.

Construction drawings ready when contractors need them.

We Give You Real Numbers Early

You need accurate infrastructure cost estimates before closing on California land or finalizing your development pro forma. We provide realistic budget numbers during feasibility. Actual construction costs based on current California market rates, not vague ranges that force you to guess. You’ll know what your water system will cost before you’re financially committed to the project.

We’ve Done This Before

We’ve designed and permitted water systems across multiple states including California. Small private well systems serving a few dozen homes to larger community water supplies. Basic distribution system extensions to complex treatment plant installations. We know what works in California’s regulatory environment, what DDW approves without extensive back-and-forth, and where you can control costs without compromising performance.

We’re Responsive

When you have a question, you get an answer, not voicemail. When DDW issues review comments, we respond immediately with the technical information they need. When contractors need clarification on drawings, we don’t slow them down. Your California project operates on tight timelines, and we match that urgency.

We Think Like Developers

We understand your business constraints. You need water infrastructure that works reliably, satisfies DDW’s requirements, and doesn’t consume your budget with gold-plated features or oversized capacity. We design systems that balance performance, regulatory compliance, and cost. Because water infrastructure that breaks your development budget doesn’t help anyone succeed.
