The Process

How a Dosing System Works

A chemical dosing system automatically injects the right amount of chemical into your water supply at the right time — no manual measuring, no guesswork.

1

Chemical Storage Tank

The chemical — chlorine, lime, fluoride or other — is stored in a dedicated dosing tank, ready to be pumped.

2

Dosing Pump Injects

A small electric dosing pump draws chemical from the tank and injects a precise amount into your water pipe or tank.

3

Mixes with Water Flow

The chemical blends into the water flow through an injection point or mixing chamber, treating every litre evenly.

4

Clean Safe Water Out

Treated water flows out to your home, borehole header tank, pool or irrigation system — consistent quality, every day.

Client Feedback

What Our Clients Say

★★★★★
"Hydroseal installed the chlorination kit on our school borehole in one day. It's been running for 18 months without any problems. Our water is now safe and we don't have to manually add chemicals anymore."

Jane Njoki
Head Teacher, Thika Primary School
★★★★★
"The solar dosing pump at our Turkana borehole has been running non-stop for over a year. Exactly what we needed — simple, reliable and no electricity required. Hydroseal explained everything clearly to our local operator."
PO
Peter Owino
WASH Engineer, UNICEF Kenya
★★★★★
"We had a problem with scale blocking our drip irrigation emitters every season. Since Hydroseal installed the anti-scalant dosing pump, we haven't had a single blocked emitter. Worth every shilling."
