IRRIGATION DISTRIBUTION & FLOW CONTROL
High-Volume Flow Control Built for Seasons of Outdoor Service

Irrigation districts, agricultural water authorities, and municipal irrigation programs distribute enormous volumes of water through networks of mainlines, lateral distribution headers, and zone control points that operate continuously during irrigation season and sit dormant through winter, repeatedly cycling between service and non-service conditions that stress valves, fittings, and support hardware that weren't designed for that pattern. The components in those systems need to hold up through decades of outdoor service, chemical treatment exposure, and the physical demands of large-volume water distribution without the corrosion that makes maintenance a seasonal ritual.

Metal Valves Corroding and Seizing in Outdoor Irrigation Distribution Systems

The pain: Metal butterfly and ball valves on irrigation mainlines and distribution headers corrode under sustained outdoor exposure, UV, moisture cycling, and the corrosive chemistry of treated irrigation water and disinfection residuals. Corroded valve stems seize over time, making the valve inoperable when flow isolation is needed for maintenance or zone switching. A valve that won't close in an active irrigation distribution system during a line repair is a significant operational problem at exactly the wrong time.
The Alsco Advantage: Asahi and Hayward thermoplastic butterfly and ball valves in PVC, CPVC, and polypropylene are completely immune to the corrosion that seizes metal valves in outdoor irrigation service, no metal stems to rust, no metal bodies to pit, no operators to freeze from corrosion buildup. UV-stable thermoplastic bodies maintain their integrity through years of direct outdoor exposure, and true-union designs allow in-line replacement without cutting distribution pipe when a valve eventually requires service.

No Flow Measurement on Irrigation Distribution Lines Creating Water Accountability Gaps

The pain: Irrigation districts and water authorities operating under conservation mandates, water rights allocations, and regulatory reporting requirements need verified, documented flow data at distribution points and delivery meters, not estimated volumes based on pump runtime or valve position. Without inline flow measurement, water accountability reports are based on assumptions rather than measurements, and districts can't demonstrate compliance with water use restrictions or identify the distribution losses that reduce delivery efficiency.
The Alsco Advantage: GF Signet paddlewheel flow sensors and Blue-White variable-area flow meters installed on irrigation mainlines and zone delivery points provide continuous, verified flow data at every monitored point, supporting the water accounting, regulatory reporting, and conservation program documentation that water districts and irrigation authorities are increasingly required to produce. Plastic sensor bodies fully compatible with PVC and CPVC distribution piping add flow measurement without introducing a corrosion failure mode into the infrastructure being measured.
Relevant Products: Flow Sensors • Flow Meters • Sensor Electronics • Installation Fittings

Manual Zone Valve Operation Making Large Irrigation Networks Labor-Intensive to Manage

The pain: Irrigation distribution networks covering large acreage or multiple delivery points require zone valve operation for scheduling, rotation, and maintenance isolation. Manual operation of zone valves across a large district means field crews driving to valve locations, operating valves by hand, and confirming position by visual inspection, labor that adds up to significant operational cost across a full irrigation season and limits how dynamically the district can respond to weather, demand, and system events.
The Alsco Advantage: Asahi electric and pneumatic actuated butterfly and ball valves, and Hayward automated valve packages, allow remote zone switching, scheduled flow sequencing, and emergency isolation from central control points, without field crews at every valve location. Combined with GF Signet flow sensors providing real-time confirmation that each zone is delivering its specified flow, automated irrigation distribution systems reduce labor cost, improve scheduling flexibility, and respond to demand changes faster than manually operated systems can.

STORMWATER MANAGEMENT SYSTEMS
Infrastructure That Handles Whatever the Weather Delivers

Stormwater management infrastructure operates in the most demanding outdoor conditions of any water system, full weather exposure, UV radiation, freeze-thaw cycling, biological growth, and the sediment-laden, chemically variable stormwater that flows through collection, detention, and treatment systems after every rain event. The piping, valves, and chemical treatment components in those systems need to be specified for the outdoor environment and the stormwater chemistry, not for controlled indoor service conditions.

Stormwater Collection Piping and Fittings Degrading Under Outdoor Exposure

The pain: Stormwater collection piping and fittings in outdoor installations face the combination of UV radiation, temperature cycling from seasonal extremes, biological growth exposure, and the sediment and chemical load of stormwater runoff that accelerates corrosion and surface degradation in materials not rated for sustained outdoor exposure. Components that fail in a buried or partially buried stormwater installation are significantly more expensive to repair than components specified correctly at installation.
The Alsco Advantage: PVC Schedule 40 and 80 pipe and fittings from Spears are UV-stabilized, pressure-rated, and chemically resistant to the full range of stormwater chemistry, from standard surface runoff to mildly acidic or alkaline water in areas with industrial or urban runoff contributions. Properly solvent-welded joints with Weld-On cement and primer create permanent, fusion-bonded connections that hold through years of outdoor temperature cycling without the joint degradation that improperly specified materials develop over time.
Relevant Products: PVC Schedule 40 & 80 Pipe • PVC Schedule 40 Fittings • PVC Schedule 80 Fittings • PVC Flexible Couplings • PVC Cements & Primer

No pH Monitoring on Stormwater Discharge Creating Compliance Risk

The pain: Stormwater discharge from industrial sites, transportation infrastructure, and developed urban areas is subject to NPDES stormwater permit requirements that include numeric limits on pH and other water quality parameters. Without continuous or event-based pH monitoring at discharge points, permit holders are managing compliance blind, reporting based on grab samples that may not capture the pH excursions that occur during storm events, first flush discharge, or runoff from specific site areas.
The Alsco Advantage: GF Signet pH electrodes installed at stormwater discharge monitoring points provide inline pH measurement that integrates with site control systems for automated data logging and alarm generation when pH approaches permit limits. Sensor bodies in Ryton and PVDF configurations handle the variable chemistry and suspended solids load of stormwater better than sensors designed for clean process water, maintaining reliable measurement in the conditions that characterize real stormwater rather than laboratory samples.
Relevant Products: pH/ORP Electrodes • Conductivity/Resistivity Sensors • Transmitters • Sensor Installation Fittings • Sensor Electronics

Stormwater Chemical Treatment and pH Adjustment Infrastructure Corroding in Outdoor Service

The pain: Stormwater pH adjustment and chemical treatment systems, neutralization of acidic highway runoff, coagulant addition at detention basin inlets, and chemical treatment at industrial stormwater management facilities, operate in full outdoor exposure with the same corrosive chemistry that attacks indoor treatment systems, plus the additional environmental stressors of outdoor temperature swings and UV exposure. Metal chemical feed infrastructure in outdoor stormwater treatment service corrodes from both the chemistry inside and the environment outside simultaneously.
The Alsco Advantage: CPVC thermoplastic valves, fittings, and piping on stormwater chemical treatment systems handle both the chemical service conditions of pH adjustment and coagulant feed chemistry and the outdoor environmental exposure of stormwater infrastructure, with no internal corrosion from chemical contact and no external surface oxidation from outdoor exposure. Blue-White peristaltic metering pumps on chemical feed lines deliver precise, repeatable treatment chemical dosing in materials rated for the corrosive chemistry of stormwater treatment programs.

RECLAIMED WATER & WATER REUSE SYSTEMS
Reuse Programs Demand Materials Rated for What's Actually in the Water

Reclaimed water, treated wastewater returned to beneficial use for irrigation, industrial cooling, groundwater recharge, and environmental flows, is not clean water. It contains treatment chemical residuals, elevated dissolved solids, trace contaminants, and in many cases disinfection chemistry that makes material compatibility a genuine specification requirement. Piping and valve systems in reclaimed water distribution must be correctly specified for the actual chemistry of the reclaimed water stream, not specified to potable water standards that don't reflect what's flowing through the system.

Reclaimed Water Chemistry Attacking Piping and Valve Materials Specified for Potable Service

The pain: Reclaimed water systems that reuse piping and valve specifications from potable water distribution, standard metal valves, galvanized fittings, and materials selected for clean water service, discover that reclaimed water chemistry produces accelerated corrosion, seal degradation, and component failure timelines far shorter than potable water equivalents. The elevated chlorides, total dissolved solids, and disinfection chemistry in reclaimed water are hard on metals and on elastomers not selected for the actual service conditions.
The Alsco Advantage: PVC, CPVC, and polypropylene thermoplastic valves and fittings are chemically inert to the reclaimed water chemistry that attacks metals and degrades inappropriately specified elastomers, providing corrosion-immune distribution infrastructure that holds up to the actual chemistry of reclaimed water rather than the idealized chemistry of potable water specifications. Asahi ball and butterfly valves with EPDM seats rated for reclaimed water chemistry provide the corrosion immunity and operational reliability that reclaimed water distribution systems require over a service life measured in decades.
Relevant Products: Ball Valves • Butterfly Valves • PVC Schedule 80 Fittings • CPVC Schedule 80 Fittings

Flow Measurement on Reclaimed Water Distribution Lines Required for Permit and Reuse Accounting

The pain: Reclaimed water reuse programs operate under water reuse permits that require documented measurement of reclaimed water delivered to each permitted end use, landscape irrigation, industrial cooling, agricultural application. Without metered flow data at delivery points, reclaimed water programs can't demonstrate permit compliance, can't track water savings against conservation program targets, and can't generate the billing records that support the economics of reclaimed water programs.
The Alsco Advantage: GF Signet flow sensors on reclaimed water delivery headers and end-use metering points provide continuous, verifiable flow data at every monitored point, generating the documented delivery records that reclaimed water reuse permits require, supporting conservation program accounting, and providing the data foundation for equitable reclaimed water billing. With sensor bodies rated for the chemistry of treated wastewater effluent, they maintain measurement accuracy in the actual service conditions of reclaimed water rather than drifting in the chemistry that clean water sensors weren't designed for.

WATER DISTRIBUTION INFRASTRUCTURE
The Valves, Piping, and Support Systems Behind Every Distribution Network

Municipal water distribution systems, rural water district distribution networks, and water authority transmission infrastructure handle treated potable water under continuous pressure through piping systems that must remain leak-free, corrosion-free, and operationally reliable for decades. The valves, fittings, chemical treatment components, and support hardware in those systems determine how much of the water authority's maintenance budget goes to distribution system repairs, and how much goes to delivering water to customers.

Corrosion Inhibitor and pH Adjustment Chemical Feed Lines Requiring Continuous Maintenance

The pain: Water distribution corrosion control programs, lime addition, caustic soda injection, ortho-phosphate feed, deliver treatment chemistry through piping and valve systems in direct contact with the treatment chemicals themselves. Metal valves and fittings in corrosion inhibitor feed lines corrode from the same chemistry they're delivering, creating a maintenance burden on the infrastructure that's supposed to reduce corrosion in the distribution system being protected.
The Alsco Advantage: CPVC and PVC thermoplastic valves and fittings on corrosion inhibitor and pH adjustment chemical feed lines handle the full range of water treatment chemistry, lime slurry, caustic soda, orthophosphate solutions, and fluoride, without the corrosion that degrades metal components in those services. Blue-White peristaltic and diaphragm metering pumps on chemical feed lines deliver precise, repeatable treatment chemical dosing in pump configurations rated for the specific chemical, eliminating the dosing variability of manual addition and the corrosion failure mode of incorrectly specified metal dosing components.
Relevant Products: Ball Valves • CPVC Schedule 80 Pipe • CPVC Schedule 80 Fittings • Diaphragm Pumps • Chemical Tubing • Check Valves

Outdoor Pipe Support Hardware Corroding on Water Distribution Infrastructure

The pain: Aboveground water distribution piping, pump station discharge headers, treatment facility yard piping, and exposed transmission main supports rely on steel strut and pipe clamp hardware that corrodes under outdoor exposure, UV, moisture, and the humid, chemically active environments of water treatment and pumping facilities. Corroded support hardware generates safety findings, loses the structural integrity the piping system depends on, and creates replacement work in outdoor locations where access may require equipment.
The Alsco Advantage: Fiberglass reinforced plastic strut channel and fiberglass pipe clamps provide structural pipe support that is completely immune to the outdoor corrosion conditions of water distribution infrastructure, no rust, no coating failure, no structural degradation from moisture and chemical atmosphere exposure over the operating life of the facility. For water pumping stations, treatment facility yard piping, and aboveground distribution infrastructure in outdoor environments, fiberglass strut eliminates the corrosion maintenance cycle on the support system for the life of the installation. Steel strut in appropriate finish is available for indoor, dry utility areas where outdoor corrosion conditions don't apply.

Remote Pump Station and Distribution Valve Operation Requiring Field Crew Dispatch

The pain: Water district pump stations, pressure reducing valve stations, and zone isolation points in distribution networks that require manual valve operation demand field crew dispatch for every routine switching, scheduled maintenance isolation, and emergency response event. In a large distribution network, the labor cost of manual valve operation accumulates across every operational event throughout the year, and in an emergency isolation scenario, manual response times are measured against consequences that automated systems prevent.
The Alsco Advantage: Bonomi electric and pneumatic actuated valve packages, and Asahi Smart Pack actuated thermoplastic packages, allow remote operation of pump station isolation valves, distribution zone valves, and pressure management valves from SCADA and control center systems, eliminating field crew dispatch for routine and emergency valve operations. Spring-return pneumatic actuators provide fail-safe closure during power outages, ensuring that distribution system isolation defaults to a safe state when utility power fails.

Drum and Tote Chemical Transfer in Water District Chemical Handling Areas

The pain: Water districts and irrigation authorities that handle bulk treatment chemicals, liquid chlorine alternatives, pH adjustment reagents, corrosion inhibitors, and coagulants, in drums and totes face the same chemical transfer spill risk and operator exposure concerns as any industrial chemical handling operation. In a water district facility, a chemical spill near a drinking water treatment system carries both safety and public health implications beyond the immediate incident.
The Alsco Advantage: Polypropylene drum pumps with chemical-compatible tubing and cam and groove couplings provide controlled, contained chemical transfer from bulk containers to day tanks and dosing system inlets, in materials verified for compatibility with the treatment chemicals used in water distribution programs. Polypropylene and PVDF cam and groove couplings at tank connections provide secure, spill-controlled chemical transfer connections that eliminate the spill risk of manual container handling in water district chemical storage areas.

Water Management Infrastructure FAQs

Q: What thermoplastic materials are recommended for reclaimed water distribution piping and valves?
A: Reclaimed water chemistry varies by source and treatment level, but typically includes elevated dissolved solids, chloride content, disinfection chemistry residuals, and trace organic compounds compared to potable water. PVC Schedule 40 and 80 pipe and fittings are appropriate for reclaimed water distribution piping within PVC's service temperature range, they are chemically resistant to the reclaimed water chemistry that accelerates corrosion in metal distribution pipe. For valves, PVC and CPVC thermoplastic ball and butterfly valves with EPDM seats are generally appropriate for reclaimed water service. For reclaimed water with elevated chloride content or disinfection chemistry concentrations that push the limits of PVC's service range, CPVC provides improved chemical resistance. Our team can verify material recommendations for your specific reclaimed water chemistry before you specify distribution system components.

Q: What GF Signet flow measurement configurations are appropriate for irrigation district delivery metering?
A: For irrigation district delivery metering, GF Signet paddlewheel flow sensors in tee or saddle fitting installations are the standard configuration for distribution header and zone delivery metering, providing continuous, verifiable flow data in a thermoplastic sensor body compatible with PVC and CPVC distribution piping. For mainline transmission metering where non-invasive measurement is preferred or the line can't be taken offline for sensor installation, GF Signet ultrasonic clamp-on flow meters provide accurate flow measurement without pipe penetration. All configurations output industry-standard 4-20mA and pulse signals compatible with SCADA, telemetry, and data logging systems used in water district operations.

Q: Why use fiberglass strut and pipe clamps on outdoor water management infrastructure instead of galvanized steel?
A: Outdoor water management infrastructure, pump stations, treatment facility yard piping, aboveground distribution headers, and stormwater management structures, subjects structural support hardware to the combination of UV radiation, rainfall and humidity cycling, and in many cases chemically active environmental conditions from treatment chemical off-gassing or stormwater chemistry. Galvanized steel strut corrodes under sustained outdoor exposure in those conditions, losing coating integrity, developing rust, and losing structural load capacity over time. Fiberglass reinforced plastic strut and pipe clamps are completely immune to outdoor corrosion, no rust, no coating failure, no loss of structural integrity from weather and chemical exposure, providing the full service life of the infrastructure they support without a corrosion maintenance program of their own. For water management facilities with long operating lives and limited maintenance resources, the lifecycle cost advantage is meaningful.

Q: What Blue-White metering pump configurations are available for water district chemical feed applications?
A: Blue-White peristaltic metering pumps are available in flow ranges appropriate for water district chemical feed applications from small rural water systems to large municipal distribution programs. For corrosion inhibitor and pH adjustment chemistry, lime slurry, caustic soda, orthophosphate solutions, peristaltic designs handle the viscosity variability of slurry chemistry and the off-gassing characteristic of caustic solutions better than diaphragm designs. For fluoride and coagulant dosing, both peristaltic and diaphragm configurations are available depending on the specific chemical and flow rate requirements. Our team can identify the correct pump type and flow range for your specific water district treatment chemistry and system capacity.

Q: Can actuated valves be integrated with SCADA systems used in water district operations?
A: Yes. Bonomi electric actuated valve packages and Asahi Smart Pack actuated thermoplastic valves are available with standard control wiring configurations, open/close, modulating, and position feedback, compatible with the SCADA and telemetry systems commonly used in water district and utility operations. Electric actuators with 4-20mA position feedback allow valve position to be monitored and logged by SCADA alongside flow and pressure data from other field instruments. For remote pump stations and distribution valve locations, spring-return pneumatic actuators provide fail-safe closure during communication or power failures, ensuring that loss of SCADA control doesn't leave a critical distribution valve in an unsafe position.

Q: Do you stock components for Banjo liquid handling systems used in agricultural water management applications?
A: Yes. As a Platinum Banjo Distributor, we maintain the complete Banjo product line in stock, ball valves, manifold systems, manifold fittings, cam and groove couplings, centrifugal pumps, and tube fittings used in agricultural water management applications including irrigation water supply systems, fertigation equipment, chemical injection for irrigation water treatment, and nurse tank transfer systems.
