February 2026 - Water Consumption

Written By philip tamba

Our monthly reports show the latest trends in water consumption data and placing these in the context of the DMDO’s business model, which is to share in the revenue generated from the sale of water to cover its operating expenses and repay investment.

The report shows data from district to household.

Any questions or feedback, please contact me, Victor William, at victor80.vw@gmail.com.

1. Lindi District Water Operator (CBWSO) Data

Lindi District Rural Water Consumption: **Awaiting data from CBWSOs**

Notes on Water Operator Revenue vs. Operating Expenditure

  • Revenue not ‘actual’ - calculated by litres consumed x TZS5 / litre.

  • TZS5 / litre is not current price but the affordable price that DMDO business model relies on.

  • DMDO business model assumes suplus used for:

    • Water Operator service improvement;

    • DMDO (a.k.a. Rural Water Intermediary) Operating Costs; and

    • Return-Seeking Investor in Water Supply Infrastructure.

  • Current Problem is Low Price and Revenue Loss

Digitisation of Water Supply (through Prepaid Metres) addresses Revenue Loss problem.

2. DMDO Footprint Data

  • Chiuta & Mikongi Water System - [what to say?]n.

  • Mnazimoja & Malungo Water System: [what to say?].

  • Mindu Water System: [what to say?].

3. Household Connection Data

The DMDO has installed prepaid meters at 8 households in 4 villages within 3 Water Systems. These are pilots to show that consumption is much higher in household connections and that this supports a financial product in which the household connection can be financed and that debt serviced out of revenue from increased consumption.
