Service Overview

Gatundu Water & Sanitation Company provides sewerage and sanitation services to safeguard public health and protect the environment. We manage wastewater collection, conveyance and treatment in line with applicable standards, and we work with customers to keep the sewer network operating reliably.

Whether you need a new sewer connection, clarity on your account, or urgent help with a blockage or overflow, our teams coordinate response and advise on the right next steps within the licensed service area.

What we focus on

Effective sanitation depends on well-maintained sewers, responsible use of the system, and quick reporting when something goes wrong. We prioritise safe disposal of wastewater, network integrity, and clear communication with households and institutions.

Clean water and safe sanitation go together: protecting communities means keeping both supply and sewer services dependable.

Frequently Asked Questions

Quick answers about sewer and sanitation services. For account-specific information, contact customer care with your account number.

  • How do I report a sewer blockage or overflow?
    Report it as soon as possible through our fault-reporting channel (How To — Report Fault) or call customer care. Share the location, a short description, and photos if it is safe to do so.
  • Can I connect my property to the sewer network?
    New connections are subject to technical assessment, availability of sewer infrastructure, and completion of the official application process. Start from Apply for Water Connection or contact the office for sewer-specific guidance.
  • What should not be put into the sewer system?
    Avoid fats, oils, wet wipes, sanitary products, chemicals and solid waste that can block pipes or harm treatment processes. Blockages can cause backups and environmental risk for neighbours and the wider community.
  • How are sanitation charges reflected on my bill?
    Billing rules depend on your tariff category and whether water and sewer are billed together. For payment options, see Pay Bill or ask billing support for a statement explanation.
