Water Tower Supply

Water tower summary

Millions investment on the land, construction

Water treatment cost

•High risk of water pollution: snake, mouse,

bug and small animal

•Keep the temperature in winter to prevent

freezing

Lon-Term maintenance

Insufficient pressure, unstable water supply

Clean water tower and scale regularly

No friendly environment and landscape

Customer amount and types limited

Water tower construction：

Waste time, big investment, and risk

contamination

Water tower maintenance:

Waste money, waste time

Why towerless water supply summary better

•Low investment and friendly environment and

landscape.

•Direct water supply, stable water pressure,

regardless of water consumption.

•Power saving and low noise.

•Fully automation control and monitoring, remote

control, low operating costs, and low maintenance,

reliable operation.

•Automatic switching of backup power in case of

power failure and emergency, without interruption

of water.

•Bypass design, low-cost backup power supply,

reduce the risk of water outage.

•All metal closed-loop design, isolates drinking water

from pollution, small animals, and bugs.

Continued

•PID negative feedback closed-loop control system

can arbitrarily set the water supply pressure and

expand the number and variety of users in a wide

range.

•Preset sleep state at night, automatically shut

down and enter sleep state when not using water,

saving energy consumption. Automatically wake

up and enter the working state when the water

pressure drops.

•Comprehensive water pump protection: water

shortage, short circuit, overloads, heat, jams,

phase loss or unbalance.

•Integrated structure, highly intelligent integrated

design. The size of control panel is very small and

occupies a small area, which can be flexibly placed.

Closed-Loop Design Water Supply System:

Isolates drinking water from pollution, small animals, and bugs.

Water tower mixing supply

Upgraded existing water tower

1. Existing water tower as backup

2. Upgrade to towerless water supply

•Reduce maintenance cost

•Reduce water pollution

•Stable pressure and water supply

•Realize automatic control, monitoring and

remote control

•Extending the number and variety of users

•24/7 service

Towerless water supply Summary

Continued***

•A normal operating pressure of 35 pounds per square inch (psi) throughout the system. A minimum pressure of 20 psi

during fire fighting, line flushing, other unusual conditions.

•In the United States the average is approximately 568 liters (125 gallons) per person per day.

•The world average is estimated to be approximately 60 liters (16 gallons) per person per day

•There will be times during the day when water consumption is much greater than a pumping station averages of water per

minute, such as peak time, morning, and evening

•Average daily flow (ADF), Peak hourly flow (PHF) and peak daily flow (PDF)

a) 2.4 for peaking from average daily flow (ADF) to PDF

b) 1.25 for peaking from PDF to PHF
