NAWASSCO — the Nakuru Water and Sanitation Services Company — supplies treated water and sewerage to roughly 350,000 residents and businesses across Nakuru City, Naivasha, and Nakuru County peri-urban areas. The company has been one of Kenya's better-rated water utilities by WASREB in recent years, with relatively reliable service and a working M-PESA billing system. This guide explains exactly how to pay, what your bill components mean, and the small things that matter for new residents.

How to pay step-by-step

  1. Find your monthly NAWASSCO bill (paper or SMS).
  2. Note the account number (6-8 digits, top of bill) and the amount due.
  3. Open M-PESA → Lipa na M-PESA → Pay Bill.
  4. Enter business number: 111444.
  5. Enter your NAWASSCO account number as the account.
  6. Enter the bill amount in KES.
  7. Confirm with PIN.
  8. Save the M-PESA SMS — your transaction code is your proof of payment.

Where to find your NAWASSCO account number

Printed on every NAWASSCO bill. Lost the bill?

  • SMS your meter number to NAWASSCO customer service for an account lookup
  • Visit the NAWASSCO office on Kenyatta Avenue, Nakuru
  • Call NAWASSCO customer care: 0719 050 100 / 0700 770 770
  • Use the NAWASSCO self-service portal at nawassco.co.ke if available

What's on a NAWASSCO bill

Your monthly bill typically shows:

  • Account number — 6-8 digits, top of bill
  • Customer name and address
  • Meter number — for technical identification only
  • Previous reading and current reading in cubic metres
  • Consumption = current minus previous
  • Water charge based on consumption × applicable tariff
  • Sewerage charge typically 60-75% of water charge if connected to sewer
  • Meter rent KES 100-200 fixed per month
  • VAT at applicable rate
  • Outstanding balance from prior months if unpaid
  • Total amount due
  • Due date — typically 21-25 days from bill issue

NAWASSCO tariff structure (2026)

NAWASSCO uses WASREB-approved tariff bands. For domestic users (subject to confirmation):

  • 0-6 m³ (lifeline) — ~KES 50-65/m³
  • 7-20 m³ — ~KES 80-100/m³
  • 21-60 m³ — ~KES 110-130/m³
  • Over 60 m³ — ~KES 140-170/m³

Commercial and institutional bands are higher. Schools and hospitals have specific institutional tariffs. Check the official tariff schedule on nawassco.co.ke for current rates.

NAWASSCO prepaid water

NAWASSCO has been progressively rolling out prepaid water meters across Nakuru, especially in tenant-heavy areas like Section 58, Pipeline, and Bondeni. Benefits of prepaid:

  • No monthly bill — buy credit via paybill 111444 in advance
  • Meter cuts off automatically when credit runs out — no late fees, no disconnection charges
  • You see real-time consumption on the meter display
  • Tenants and landlords can split easily (each tenant has own meter)
  • Often slightly cheaper per cubic metre due to administrative savings

Apply at the NAWASSCO office to switch from postpaid to prepaid. Install fee currently runs ~KES 4,500-7,000.

When your bill suddenly spikes

A sudden 2x or 3x increase in your water bill is almost always one of three things:

  1. A leak. Check meter with all taps closed. If it spins, you have a leak. Toilet running silently is the most common culprit, followed by an underground pipe leak between the meter and your house.
  2. Estimated bill. If the meter reader couldn't access your meter, NAWASSCO estimates based on your historical average plus a buffer. Submit a current reading via SMS or photo to request re-billing.
  3. Tampered meter or wrong reading. Rare but happens. Photograph your meter monthly. If readings on the bill don't match your photos, dispute with evidence at the NAWASSCO office.

If you fall behind

NAWASSCO disconnects accounts after roughly 60 days of unpaid bills. Reconnection costs:

  • Reconnection fee: KES 1,500 - 3,000
  • Full outstanding balance must be cleared
  • Field visit to physically reconnect (24-72 hours after payment)

Engaging early is always better. If you can't pay in full, walk into the NAWASSCO office and propose a payment plan. They generally accommodate genuine hardship cases with a partial payment up front and a written plan for the balance.

Common NAWASSCO payment mistakes

  1. Confusing 111444 with 111000 / 144111. NAWASSCO is exactly 111444. Triple-check before sending.
  2. Paying ELDOWAS by mistake. ELDOWAS is Eldoret (paybill 511000), NAWASSCO is Nakuru (paybill 111444). They're not interchangeable.
  3. Missing the prepaid SMS. If you have a prepaid meter, the credit token arrives by SMS shortly after payment. If you don't see it within 30 minutes, contact NAWASSCO with your M-PESA transaction code.
  4. Paying with the wrong account when on multi-property. If you own multiple Nakuru properties, each has its own NAWASSCO account. Pay the correct account for each property — payments to the wrong account require manual reallocation.
