Alderwood’s Discount Programs

The Alderwood Water & Wastewater District offers two low-income discount programs for residential customers. 

Both programs offer a discount of 34 percent, and require that you have a total annual income including that of a spouse or any co-tenant(s) not exceeding $40,572, in addition to meeting other criteria.

Alderwood Water & Wastewater District offers a Toilet Replacement Program that enables District retail customers (you must pay your water bill to Alderwood) to replace their old toilets with efficient water-conserving toilets in order to save water and money.

Participants will receive up to $75 rebate for a qualifying toilet installed (1 toilet per customer). Toilets must be WaterSense Labeled and be on EPA’s list of High Efficiency Toilet (HET) models which is linked to this page.

Applications will be processed on a first-come-first-serve basis until allocated funds are exhausted.
