Controlling (limiting) flow rate of irrigation water system

Case Study – Irrigation System for Vineyards

Background

In the vineyards surrounding Adelaide, South Australia, irrigation is a standard agricultural practice. To reduce costs and improve sustainability, reclaimed water is commonly used instead of bore water.

A key challenge in this setup is ensuring that all winegrowers receive an equal and fair share of reclaimed water—regardless of their distance from the water source. Additionally, there are strict regulations regarding daily water allowances, and exceeding these limits can result in substantial fines for the user.

Solution

To ensure compliance and fairness, BT-Maric Flow Control Valves were installed at each pipeline connection (see blue arrow in accompanying diagram). These valves deliver a pre-set, constant flow rate, independent of pressure variations or user location.

This simple, mechanical solution ensures that:

• Each grower receives their allocated share of water
• Overuse is prevented, avoiding regulatory penalties
• System integrity is maintained across varying terrain and distances

BT-Maric valves thus play a critical role in supporting equitable water distribution, regulatory compliance, and efficient resource use in agricultural irrigation systems.

Benefits of Installing BT-Maric Flow Control Valves

1. Fair and accurate water allocation

BT-Maric Flow Control Valves ensure that each user receives their agreed daily water allowance, regardless of distance from the water source or the number of other users connected to the same pipeline.

2. Tamper-proof design for equal access

The valves cannot be adjusted or manipulated, ensuring that all users have equal and secure access to irrigation water.

3. Pressure-independent performance

Each valve delivers a pre-set, constant flow rate, regardless of pressure drop or pipeline length—preventing overuse and reducing the risk of regulatory penalties.

4. Cost-efficient and maintenance-free

With no moving parts or need for servicing, BT-Maric valves offer a low total cost of ownership.

5. Long service life

Built to last, each valve has a life expectancy of up to 20 years, even in demanding outdoor environments.

6. Supports water conservation

By regulating and limiting water use, the valves help preserve the world’s most valuable resource – water.

A simple, economical, and effective way to limit water flow and reduce consumption is to install BT-Maric Constant Flow Valves.

Looking to Improve Water Efficiency in Irrigation?

• Are you searching for a reliable solution to save water in your irrigation systems?

• Do you need to control water distribution evenly across multiple outlet points, regardless of their distance from the water source?

If so, BT-Maric Flow Control Valves may be the solution you’ve been looking for – delivering constant, tamper-proof flow to every point in your system.
